Impacts

Given the nature of these banded snowfall storms, we will expect some sort of travel impact Monday night and Tuesday morning. I suspect the Tuesday morning commute could be difficult if this storm comes together right.

Monday Night – Tuesday Morning

  • Possibility of slick roads
  • Quick bursts of intense snow will overcome road warming and cause snow and ice to accumulate
  • Quick bursts of snow will also mean snowplows may struggle to keep roads clear during the storm

 

By the way, it’s always a great idea to have these items in your car when you need to be out driving in snow. As we know in Colorado a minor storm can turn into a major one very quickly, so be prepared!

 

There’s still a lot of moving parts with this storm so a lot of these details are preliminary and may change. There is still a fair amount of model uncertainty, but the snowfall amounts we gave above encompass most of them and discount the outliers.

We will continue getting data in on Sunday that will change our forecast one way or another so keep an eye on our site and facebook page for changes!
