Saturday PM Palmer Divide Storm Update

Not many major changes to what we are seeing tonight based on new data coming in. A lot of the mid and shorter range models are coming in and have dropped snow totals just ever so slightly across the area.

Snow banding is possible so some areas may over perform while others under perform.

As we’ve been saying all along, the way this storm system is moving in (the direction and moisture content) is not conducive to a major snow storm along the front range. The biggest impacts will be the cold temperatures the areas sees on Sunday and into Monday morning.

Still, we can’t discount a few quick bursts of moderate snow overnight tonight and combined with the much colder temperatures could make some areas a bit tricky for travel. The jet stream is overhead and as we’ve seen that can do crazy things to our snow totals for certain areas. Expect some areas to see slick roads overnight into Sunday especially South and West of Denver. The foothills should still see decent amounts of snow so I’d expect the travel conditions to be a bit trickier up that way.

Updated Timing, Impacts and Snowfall Amounts

Timing

  • The front is moving through Denver and Southward towards the Palmer Divide as of about 7:30PM
  • Expect precipitation to start as rain but may quickly change over to snow this evening
