What To Expect With This Storm in and Around the Palmer Divide

This specifically means what to expect in Castle Rock, Larskspur, Franktown, Elizabeth, Kiowa, Monument and surrounding areas out towards Limon.


  • Expect windy conditions throughout the day Thursday beginning after 12PM. This will mean increased fire danger and strong winds that may affect high profile vehicles on the highways.
  • Precipitation begins as rain moving into the area late tonight (models generally show this starting after 9PM)
  • Transition to all snow sometime around midnight
  • Heavy snow and strong winds will create blizzard conditions along the Palmer Divide from midnight to Friday morning
  • The storm should begin to move out by late Friday morning into Friday afternoon.

Snow Accumulations

  • Castle Rock and Northern Palmer Divide can expect 6-12 inches total accumulation by Friday afternoon
    • Castle Rock, Pinery, Franktown, Elizabeth, Kiowa
  • Areas over and near Monument hill can expect 7-14 inches of accumulation
    • Larkspur, Palmer Lake, Monument, Black Forest
  • Localized amounts of 8-16 inches will be possible


  • Strong northerly and northwesterly winds will make for blowing and drifting snow
  • Visibility could drop below 1/4 mile in wind-prone areas


  • Heavy snow, especially after midnight into the early morning hours of Friday will make travel difficult. Road closures will be possible in some areas.
  • Roads are expected to become icy and snowpacked
  • Nonessential travel is not recommended after midnight in the Palmer Divide region.


At the end of the day folks, this storm is a quick hitter. It will be at its worst while most of us are sleeping and will make for a very nasty Friday morning commute. It doesn’t warrant a trip to the store as the roads should be in much better shape by Friday afternoon and evening. The snow will be very heavy at times from midnight to 9AM so keep that in mind.

If you are travelling back to the area from spring break, expect tricky travel conditions through the day Friday especially if you are coming back from the South or West. I-25 through Monument Hill will be treacherous during the day and I-70 near the divide (Eisenhower Tunnel) could be tricky as well.

As the storm moves out Friday I’d expect better road conditions later in the day and much improved travel conditions through the region on Saturday, so consider that if you are travelling and can flex your times a bit.
