Drought Status Worsens in Colorado as Dry Conditions Continue

Colorado Weather Radar | Snow | Rain | Live Radar | January 10, 2018

4PM Radar on January 10, 2018

Despite a quick hitting storm that brought beneficial rain to the plains and a bit of snow and ice to some areas along the Palmer Divide, it simply wasn’t enough to make a dent in our longer term dry conditions. We will need several more storms with much more moisture and longer durations if we hope to start catching back up to where we should be.

Drought Worsens Across Colorado

Colorado Weather | Drought Status January 2018 | US Drought Status

Current drought status across Colorado

Expanding from last week, abnormally dry conditions cover most of the central and northern mountains as many of those areas are well below their average snowpack numbers for this time of year. Moderate drought expands to cover most of the front range and Southeastern Colorado. Finally, severe drought was expanded to encompass larger portions of Southwestern Colorado.

Colorado Weather | Drought Status January 2018 | Palmer Divide Colorado | Drought Status

Drought status along the Palmer Divide region as of January 11, 2018

If we zoom in closer to home, you can see nearly every community across the Palmer Divide is now included in the Moderate Drought status designation.

What Does Moderate Drought Mean?

According to the Climate Prediction Center:

This level of drought involves “some damage to crops, pastures; streams, reservoirs, or wells low, some water shortages developing or imminent; and voluntary water-use restrictions requested,” according to the monitor.

For us in Colorado it means expect very dry vegetation and higher fire danger. Expect Fire Weather Warnings to be more common, especially on warm and windy days.

We will continue to keep an eye on conditions but sadly many models are pointing to continued dry conditions, especially East of the Continental Divide for the near and medium term.

Everybody is Asking; Where’s The Snow?

Nobody Expected It To Be This Warm and Dry This Year

I’ve heard this comment a lot from a few folks and in the nicest way possible I say, “that’s absolutely wrong.” There is nothing surprising about Castle Rock, the Palmer Divide, the mountains or even most of the state of Colorado being in drought status in early January during a La Nina year.

Colorado Weather | Drought Status January 2018 | US Drought Status

Current Colorado Drought Status as of January 4, 2017

If you’ve followed along with us for some time, you noticed how much we talked about La Nina through the late summer and fall months. We even expressed concerns about windy, dry and warm days as early as October. If you follow other meteorologists, you’ve heard them say the same things. The fact is while no two La Ninas are exactly the same, there are some larger scale patterns and trends that take place during these types of years.

Fall and Winter So Far

The National Weather Service in Boulder put together some great graphics that explain what type of patterns we typically see with La Ninas in the Western United States. If you look closely, you’ll notice that we have seen these patterns largely verify for Colorado’s weather so far this year!

La Nina Fall | Colorado Weather | La Nina weather pattern | Castle Rock Weather | Palmer Divide Weather

Click on the image to see it at full size

In fall Colorado tends to see much warmer than average temperatures and very little moisture as the jet stream stays North of the state and tends to steer storms systems away. High pressure aloft keeps the air very dry and warm with windy conditions. This is nearly exact to what we saw this fall. Check out our November climate summary to find out just how warm and dry we were! You’ll notice September and October were both warmer and drier than average as well.

Below is the pattern we expect to see right about now.

La Nina Fall | Colorado Weather | La Nina weather pattern | Castle Rock Weather | Palmer Divide Weather

By early winter the pattern shifts a bit, but dry conditions remain

By the time we reached late December we began to see more swings between warm sunny days with occasional cold fronts moving through to drop the temperatures. Pretty spot on to what we’d expect except the mountains remained relatively dry along with the Eastern plains of Colorado. Extremely cold air affects the Northeastern United States as we’ve seen has been the case so far this year.

 

What we expect to see later in January into February (late winter)

As we transition into the late winter months the jet stream continues to shift with the arctic jet moving Northward and the Polar jet having a pronounced high pressure ridge over the Southwestern United States. This pattern can be similar to fall so it’s worth keeping an eye on, we should probably expect more dry and windy days ahead for areas East of the Continental Divide.

While the mountains have been quite dry so far, there is no reason to think they will continue to be for right now. As the jet starts to shift, unsettled weather will become more common for the mountains, but it’s a matter of how much shifting goes on and does it set up well for the mountains to benefit?

Where’s the Snow?

Eastern Colorado

Sadly, I expect areas East of the Continental Divide to finish below average on snowfall. Not to say there’s no chance of a big storm, but our snowfall numbers are dwindling to the point where we’d have to get multiple large storms to break even. A large storm or two is possible during a La Nina year, but more than one is pretty unlikely.

Watch For: If we get any consistent snowfall along the front range, it will most likely be after mid/late February.

Colorado Mountains

I am getting a tad concerned about overall snowpack in the mountains but am not ready to panic yet. With this type of weather pattern, all it takes is a tiny shift to line up several storm with heavy snow that can bounce back the snowpack. The problem is, these snowstorms will favor Northern mountain areas the most (think Steamboat, Winter Park and the such) while the Southern mountains have a harder time getting snowfall.

Watch For: Northern mountains have a better chance for a rebound in the next month or two, keep an eye out for a jet stream shift and weather disturbances moving in from the Northwest. Southern mountains may have a tough time reaching the same snowpack numbers due to the Northwesterly component of storms.

Summary

It has indeed been dry and it looks like areas East of the Divide will remain warm, dry and windy through most of January with only small storms coming through to drop the temperature and maybe sprinkle a few snow flurries. We will keep an eye out for a pattern shift as we move into Spring, that will be the best chance to see larger snowfall for us along the Palmer Divide, but there is no guarantee we will see a large snowstorm this year.

For the mountains; don’t count them out yet. There are indications their weather pattern will get more active in the next few weeks, the key here will be how long that pattern stays active. If we don’t see a series of larger storms moving through by mid-March it will be time to get worried.

Drought Impacting Colorado to Start the New Year

Colorado Weather | Drought Status January 2018 | US Drought Status

Latest drought status for Colorado as of January 4, 2017

Large portions of Colorado have returned to drought status thanks in large part to our very dry winter we’ve had so far this year. Most areas of the state are now in at least the “abnormally dry” classification but some areas in Southwestern Colorado have been upgraded to “Moderate Drought” and “Severe Drought” levels.

For the Castle Rock area and all of the Palmer Divide, the “Abnormally Dry” classification is not surprising. The snowfall numbers for this year’s snow season are very telling…

 

Castle Rock CO Snowfall 2017=2018 | Castle Rock Snow Stats | Castle Rock Snow

For the snow year beginning September, the Castle Rock area is over 12 inches below average on snowfall. This lack of moisture and several days of above average temperatures and strong winds have done a great job of drying things out.

Things To Remember During Drought

  • Droughts can be short or long term, while we have some concerns about this particular spell… there no indication as of yet that this drought will last longer term (more than a month or two). It is something we will keep an eye on though…
  • Fire danger will remain very high. Especially on days with warm temperatures and/or high winds. Keep this in mind if you are engaging in activities that cause sparks or open flames.
  • Water those trees! When it’s this dry, the conditions can put considerable stress and strain on trees.
  • While the mountains are very dry right now, it is still quite early in the snow season up there. So as of right now, we don’t have serious concerns about reservoir levels. This is another thing we will need to keep an eye on as we move into spring.

Quick Look Ahead

Total snowfall expected through Sunday 9AM

There’s really only one good chance of snow in the next several days and the mountains will get the large majority of it. That’s not to say this will significantly up the snowpack, most areas will see between 2-6 inches… and those 6 inch areas will be a bit few and far between.

There is a small chance areas just Southeast of Denver see a bit of snow on Saturday, but we expect little to no accumulation. Models have mainly been painting a bit of snowfall in and around Elbert County with little to no snow for most other areas along the front range.

We will keep an eye on the weather over the next few days, again we don’t see any large snow storms on the horizon, but we will be watching a stronger storm system slated for the middle of next week to see if that materializes. Stay tuned!

Unsettled Weather Pattern – Weds PM Storm Update

There was a lot to be excited about last week, models were predicting a major weather pattern shift and with it the chances of the first big snows of the season. Phone apps promised 4-8 to 6-12 inches of snow on Thursday and another healthy dose of the white stuff on Saturday. We were a little bit more skeptical here at Mountain Wave Weather (as we tend to be most times.) The problem with models is that the further out they are, the more difficult it is for them to pick up on subtle details and as we know in Colorado a shift in a storm system 50 miles North or South can be the difference between several feet of snow or nothing at all. Additionally, phone apps are not consistent, they are forecasts put together by computers with no human interaction to throw out the outliers, this often results in a lot of “bouncing” forecasts.

The overall weather pattern for the Western United States and Colorado has been a large ridge of high pressure centered over our area. This feature has brought us a ton of warm and dry weather and very few solid snow storms, most leaving only a dusting to maybe an inch or two of snow on the ground. The problem is when these types of things settle in, they can be very difficult to break.

A look at the predicted setup for last week, warmer and drier air along with the jet to our North kept most of the storms away from us.


Thursday Storm System

Analysis:

I just had to share this graphic that our friends over at Weather5280 put together and posted today. It shows an excellent example of how this storm system has evolved and why it’s not looking too impressive anymore…

Credit: Weather5280 | Click the image to see it animate.

You can see how the trough continues to shift Northeast of Colorado from the starting point last Sunday and into Monday and finally today. The problem is, this entire storm system depends on our high pressure braking down and moving far enough South or West for the trough to dig into Colorado. When you have such a stubborn high pressure ridge as we have, it gets difficult to break them down and move them out. So all in all, this the main reason we’ve remained pessimistic about a decent snow out of this storm system. The snowfall falling apart for this system was more likely than it becoming a monster storm for us, so this wasn’t exactly surprising.

What to Expect:

Timing

Snow looks to move into the area beginning early Thursday morning. The latest run of the HRRR shows snow beginning sometime between 4-6 AM, so expect that for the morning commute on Thursday.

Hazards

Again with this storm, we are not expecting huge snow totals. With the very cold temperatures, wind and snowfall we will see slick spots on the roads potentially Thursday morning. Be prepared for icy conditions especially along the foothills and Western areas of the Palmer Divide.

Impacts

We expect minor to moderate travel impacts, but not widespread issues. Roads that get stuck under snow the longest will have the best potential for becoming icy. Keep this in mind for your Thursday morning commute, leave a little bit of extra time if need be.

Snowfall Amounts

Our forecast generally agrees with what the NWS is expecting so we have posted that graphic along with some of our own details below:

  • Castle Rock
    • 1-3 inches total accumulation looks good as of right now. Models have been pretty consistent showing snowfall ending up right around 1 to 2 inches.
  • Areas South and West of Castle Rock (Palmer Divide, Sedalia, etc…)
    • 1-4 inch range for snowfall
  • South Denver Suburbs
    • 1-3 inch, should see similar amounts to Castle Rock but  this storm will have a Northern bias. Expect slightly higher snow totals in and around the Denver/Boulder area
  • Elbert Area (Southeast of Castle Rock)
    • 0-3 inches, don’t be surprised to see little to no snowfall as you begin to move East of the urban corridor.

A Quick Note about Saturday’s Storm

A lot of folks have reached out to me regarding travel conditions on Saturday/Sunday. The storm Saturday looks even less impressive than Thursday’s and models have been consistently phasing out snowfall in many locations. Does this mean it won’t snow or there will be no problems? Not necessarily, but with the data we are seeing right now along with the combination of the stubborn weather pattern we are in; I’m not terrible concerned about folks travelling around on Saturday or Sunday.

My suggestion would be, stay tuned to your favorite, reliable weather source for any forecast flips or changes (whether that is us or anyone else) and we will be sure to keep an eye on it. But we don’t anticipate any major flight problems or road issues at this time.


Reach out to us with any additional questions, we know weather and travel are quite the concern this time of year! We may even do a facebook live session this week and answer any questions related to the weather over the next 3-5 days. We’ll see where that goes, for now stay warm and stay safe!

Palmer Divide Snowfall Totals – Dec 14, 2017

Snowfall Totals | Snow Storm | Snow Amounts | Castle Rock CO | Elizabeth CO | Parker CO | Palmer Ridge Weather | Palmer Divide Weather

Here’s a quick look at snow totals from our latest storm. As we had predicted, snowfall amounts were relatively light and travel impacts were minimal. We experienced the worst road conditions South and East of Castle Rock this morning over higher elevations of the Palmer Ridge.

  • Castle Rock
    • 1.0 – 1.3 inches of snow accumulation

 

  • Areas South and West of Castle Rock (Palmer Divide, Sedalia, etc…)
    • 1.5 – 3.0 inches of snow accumulation

 

  • South Denver Suburbs
    • 0.5 – 1.1 inches of snow accumulation

 

  • Elbert Area (Southeast of Castle Rock)
    • 0.8 – 1.0 inches of snow accumulation

 

  • Falcon ( NE Colorado Springs Area *by request*)
    • T – 0.2 inches of snow accumulation — downslope off the Palmer Divide squashed a lot of moisture down that way!

Our forecast was pretty spot on with this storm. Despite the models trying to push snow totals in the 2-4 inch range or even 3-6 inch range for some of these areas… we just didn’t see a lot of support for it. We kept our snow forecast on the lower side based on the type of storms we’ve seen this year and this storm looking very similar to those storms.

See our original forecast for this storm

Our next chance of snow comes on Saturday and we will have an article up on Friday tracking that storm system. Stay tuned!

Weds/Thurs Storm: Big Snow-maker or More of the Same?

If you remember yesterday, there was quite the buzz about a storm swinging a bit further South and bringing more energy that anticipated. As soon as we mentioned the thought of snow falling the internet was off! We know that it has been super dry and snow has been very hard to come by this year, we’ve gotten to the point where the mere mention of the word “snow” sends people in a tizzy! That’s ok, it’s weather!

So far precipitation along the Palmer Divide is running 0-10% of average for December. Bone dry!

We need any moisture we can get very badly, but this storm will not be a “drought buster” by any means of the imagination. In fact, this storm looks meteorologically very similar to the past several storms we’ve had. Given that information, what we can expect with this storm is similar; lots of wind, a quick shot of accumulating snow and not large amounts of accumulating snow. Let’s dive into the details:


Wednesday Night/ Thursday Morning Storm

The thing to remember about this storm is that the main energy is coming out of the West/Northwest and if you’ve been following us for any amount of time; you know that we don’t get excited about storms like this. We simply do not get big accumulating snow from storms like this.

Winter Storm | Castle Rock CO Weather | Weather Castle Rock CO | Fall 2017 | Snow Storm

Latest Nam 3K model for snowfall through Thursday evening.

Most models are in agreement with snowfall being mainly a foothills/mountains event with some accumulation on the front range. The Palmer Divide is one area we are watching as our chance of accumulating snowfall will be notably better than most areas in and around Denver. Still, all models are in agreement that this is not a major snowfall event. We can’t ignore however; just like the last storm the accumulation will hit quickly and could cause travel difficulties late Wednesday night and into Thursday Morning.

Timing

Most models have snow beginning to accumulate after midnight so expect snow falling sometime around then give or take an hour or two. This storm shouldn’t affect the Wednesday evening commute in any capacity.

Area

Along the Palmer Divide, areas in and around Castle Rock should see snow accumulation by Thursday morning. Areas South and West of Castle Rock should see slightly higher snow accumulations.

Hazards

Slick roads will be possible, especially in areas South of Denver on Thursday morning. Areas between Castle Rock and Monument will have the highest chance of larger travel impacts with roads improving as you move further North.

Snowfall Accumulation

  • Castle Rock
    • 0-3 inches total accumulation looks good as of right now. Most models have snowfall right in the 1-1.5 inch range but any cooler trend in temperatures could bump those numbers up slightly.
  • Areas South and West of Castle Rock (Palmer Divide, Sedalia, etc…)
    • 1-4 inch range for snowfall
  • South Denver Suburbs
    • 0-3 inch, should see similar amounts to Castle Rock but slightly lower due to elevation
  • Elbert Area (Southeast of Castle Rock –have to throw this one in now as we have a few people in and around this area following us now!)
    • 0-3 inches, most models have similar amounts to the Castle Rock area

Summary

Be ready for the potential of a slick drive Thursday morning, this storm won’t snow enough to cause closures or major travel impacts but will cause enough moderate impacts for some headaches.

Temperatures won’t be super cold with this storm system but it will be quite a shock to the system after several days in the 60’s!

We’ll have updates on another potential storm around Saturday that may bring us another chance of snow later this week. Additionally, you can read our medium range weather outlook here if you missed it:

And here’s some more fun reading:

Dec 11

Medium Range Weather Outlook – Castle Rock CO

A Quick Recap

It’s no secret to many of us living along the Palmer Divide that this fall has been quite dry. In fact, most areas of Colorado are much drier than normal at this point in terms of snowfall and overall precipitation. We crunched some numbers on Castle Rock’s snowfall since October 1, 2017 and the results are pretty telling…

Castle Rock CO Snowfall 2017 | Castle Rock CO Weather | Snowfall Tracker 2017 | Snow

Castle Rock Snowfall Tracker: Shows 14.9 inches below average on snowfall for October 1 – December 11, 2017

While we’ve been lucky enough to have at least a few small storms, Denver is in even worse shape with no measurable snowfall in over 60 days!

Denver snowfall 2017 | Denver Weather | Local Denver Weather | Denver CO Weather | Denver Colorado Weather

Should Denver make it to December 19th with no measurable snowfall, it would set a new record as longest streak of continuous days without measurable snowfall.


Any Change in Site?

The blocking weather pattern responsible for our very warm, dry and windy days looks like this…
(In this model ensemble, reds and oranges denote high pressure *ridging* and generally means warm and dry weather while blues denote colder and wetter areas)

Notice the strong ridge to the West. This pattern keeps us dry and warm along with areas like California and the Pacific Northwest.

This pattern has been incredibly stubborn and has seen a majority of the cooler and wetter weather sliding along the jet stream East of Colorado. In fact, some parts as far South as Texas, Georgia and Florida saw decent accumulating snow this week. This pattern looks to linger over the next 5-7 days so expect us to continue warm, windy and dry for at least that period of time.

Let’s jump ahead 7 days to next Monday…

Next week shows a more “zonal” flow but Colorado still looks to have a similar weather setup.

By next week the ridge begins to break down and shift Westward a bit, but you’ll notice the reds and oranges stay over Colorado and the Western United States. In a pattern like this we’d expect to stay mainly dry but a bit cooler with the ridge breaking down. The lines close together generally mean we will see windy conditions continue, especially across Northeastern Colorado.

So we will jump to Christmas, because everyone likes the potential of a white Christmas right?

We see some blues over Colorado and the central U.S.

Notice we see evidence of a pattern change! The trough moves out of the Northwest and could push cooler air into Colorado. There are a few things to note here:

  • This image is towards the edge of this model’s range, so it must be taken with a huge grain of salt. This is a long ways out and has a lot of time to change between now and then.
  • This looks similar to the “backdoor cold front” type of storms we’ve been seeing all year. This generally means we see colder air, a lot of wind and only minimal chances for snow.

The Takeaway?

Expect warm, windy and dry conditions with temperatures above to well above average for at least the next week. As we transition into Monday next week we should see continued dry conditions but if the models verify temperatures may be slightly cooler (depends on the winds and if we continue to downslope with the zonal pattern.)

By the way, there is a Red Flag Warning in effect for Eastern Colorado and Eastern parts of the Palmer Divide for today (December 11, 2017 ) until 5pm.

Expect to see more Fire Weather Warnings in the next 2 weeks!

There is a slight glimmer of hope for snow lovers (or at least cooler weather lovers) right around Christmas time.

If a storm does form, we have serious concerns about available moisture and if the trough sets up far enough South to bring us any upslope. There are more questions than answers about this setup as of right now.

Please do keep in mind though, being that far out, the model accuracy is noticeably lower. We don’t have high confidence in a weather pattern change and/or chances of snow just yet.

We’ll keep looking out over the next couple of weeks for a hint of any change, but right now it looks like more of the same. Keep doing those snow dances!

 

Dec 07

Afternoon Front to Bring Snow for Some

Another front and associated disturbance is moving though the area this afternoon. This system will keep our cold temperatures in place and give some areas a chance of snow this afternoon. Just like the past few systems, this one is relatively moisture starved so there isn’t much to work with in terms of snowfall.

Castle Rock CO Weather | Weather Castle Rock CO | Fall 2017 | Snow Storm

Latest HRRR snow accumulation favors areas South of Denver… mainly higher areas of Douglas County and to the West.

Timing: Expect snow showers to begin after 2-3pm and continue for a couple of hours. Snowfall amounts will be very light across most of the front range so travel impacts are not anticipated. Some very select areas may see slick roads under heavier snowfall, mainly in the foothills.

Accumulation: Most areas will see little to no accumulation. Areas South of Denver into Douglas and Elbert county can expect a bit of snow accumulation, generally in the 0-2 inch range with heavier bias towards 0-1 inches.

Impacts: Little impact from this storm beyond gusty winds and cold temperatures. Models show winds gusting between 20-30mph into the evening hours.

Northerly winds will mean upslope along the Norther Palmer Divide, while areas South see downsloping conditions

The main reason (other than how little moisture is with this storm) to why Denver and Colorado Springs won’t see much is the wind profile. A strong Northerly wind will accompany this system which causes downslope across the Cheyenne Ridge (north and into Denver) and on the other side of the Palmer Divide. Those areas will see dryer air and conditions that are not condusive to snowfall. For those of us right against the Northern and Central part of the Palmer Divide, we will get enough upslope to see a few snow showers.

Again, snowfall amounts will be light overall though, this storm will not help our dry conditions out at all really. Warmer and windier conditions will return by the end of the week.

Dec 03

Next Storm System to Bring Wind, Cooler Temperatures

A new storm system has organized across the Western United States and its effects were beginning to establish across Colorado and the Palmer Divide on Sunday.

Winds measured at Mountain Wave WX on the Palmer Divide were strong today!

Winds were quite gusty across the area on Sunday with high clouds streaming in over the area. The next storm system is digging a trof of low pressure across the Western U.S. and many places will feel the effects of this powerful storm system beginning tonight.

Winter Weather Advisory | Notable Weather | Fall 2017 | Snow Storm

The Western U.S. and Central plains have several winter weather alerts up ranging from Winter Weather Advisories to Winter Storm Warnings and even Blizzard warnings for North and South Dakota.

Noticing the lack of highlights for Colorado with this storm? Only some of our mountain areas have any type of weather alert up and they are very few and far between.

Winter Weather Advisory | Notable Weather | Fall 2017 | Snow Storm

Winter Weather Advisories for Colorado’s mountains mainly exist for areas along the Northernmost portions of the continental divide and Northwestern Colorado

Will This Storm Be Different?

As you may have gathered from the information above, we will see more of the same out of this storm. Expect strong winds, much colder temperatures and little to no snowfall for areas East of the Continental Divide. This just simply hasn’t been our year for snowfall/moisture and all indications are that we will continue to experience dry conditions for some time.

HRRR Model predicted snowfall through Monday as the storm departs the area

You’ll notice with this storm just as the last, snow really has a difficult time making it across the divide. In all honesty, while the mountains will see snow their totals don’t look impressive either. Strong downsloping winds are agreed on across the models and so is a notable drying componente East of the divide. This storm is not pushing a ton of moisture into Colorado, but the mountains will catch and trap what little bit makes it into the state.

The big news will be the shock of much cooler temperatures after our prolonged period of above average and record breaking warmth.

We’ll keep an eye out for any interesting storms for the area, but as we see it now… the next 7-10 days show a cool but dry pattern. Sadly, the mountain ski areas are going to have a slow start as we are already into December and many areas are only at 50% of average on snowpack. We don’t see any large storms changing that anytime soon!

Castle Rock November 2017 Weather Summary

Castle Rock Weather | Castle Rock Co Weather | 80109 weather | 80108 Weather | November 2017 Weather Summary

Castle Rock Weather Summary

The highlights of this month were definitely the sunsets caused by strong westerly flow aloft along the front range and over Castle Rock. It seems nearly every night we were treated to amazing pinks, purples and reds in the mountain wave clouds that hung over the front range. These clouds are often a sign of warm conditions as we’ll usually see down-slope conditions form along the front range.

Looking back at November 2017, will most likely remember the sunsets, the extremely warm temperatures and dry conditions. Aside from the sunsets, the weather was relatively boring with few storm systems bringing moisture to the area and a lack of cold air form fronts that never seemed to get quite that deep into Colorado.

In one word with regards to temperatures for Castle Rock; November was what I like to call a scorcher! The average temperature finished 6.16 degrees above average which is quite significant. In fact, nearly the entire state saw well above average temperatures and below average precipitation.

Weather in Castle Rock Colorado | Castle Rock Co Weather | Palmer Divide Weather | Colorado Weather Statistics | November 2017 Temperature Departure from Average

The entire state of Colorado saw above average temperatures for November 2017. Most areas along the front range finished 5-10 degrees above average with some mountain locations pushing over 10 degrees above average!

 

Weather in Castle Rock Colorado | Castle Rock Co Weather | Palmer Divide Weather | Colorado Weather Statistics | November 2017 Precipitation Departure from Average

Nearly all of the state saw below average precipitation (with a few exceptions.) Denver and surrounding areas were hit especially hard finishing in the 10-30% of average while areas along the Palmer Divide finished in the 30-50% of average range.

November 2017 Highlights

Castle Rock Weather | Castle Rock Co Weather | Climate Summary | November 2017 Temperatures | November 2017 snowfall | November 2017 Weather Highlights

The main highlights for the month were the strong wind gusts, on many days we had winds gusting to 40MPH. Additionally, we had a very warm day on the 27th, reaching 76.9 degrees in Castle Rock, this may be a new record for the area… I’ll have to check into it. Finally, snowfall was an abysmal 2 inches, which is 5 inches below our average. Hopefully we can get a pattern change into December to bring us cooler air (this looks likely for early December) and some moisture (still not seeing a strong signal for big snow storms sadly.)
