Cold and Snowy Week Ahead

Posted Saturday, February 1st, 2020 by Eric McNamee

TL;DR: A potent winter storm moves into the state tomorrow night, bringing widespread and COLD temperatures. Looking around 1-2 feet of snow for most mountain locations, possibly more in some locations.

Today was an absolutely stellar day to get out there with mild temperatures and bluebird skies. Felt a lot more like March than the first day of February. However, this all changes tomorrow night as a potent winter storm moves into the state.

Short-Term: A deep upper-level trough will dig into the western US during the day tomorrow, with a strong cold front associated with it moving through the northern part of the state tomorrow night. Timing of the frontal passage is looking around tomorrow evening along the Wasatch front, with snow filling in later in the night. The airmass accompanied with this trough will be VERY COLD. The addition of lots of moisture and unstable northwesterly flow will allow for a prolonged period of moderate-to-heavy snow Monday.

Most mountain locations will fair pretty well and should see anywhere from 1-2 feet of snow by Tuesday morning, with some spots possibly seeing more. Conditions should be prime!

We should start to clear out Tuesday as the trough exits the region and a ‘dirty ridge’ parks itself over the west coast.

Long-Term: The ‘dirty ridge’ that sets up over the west coast will allow for shortwave troughs to move into the state in the latter half of next week. None of them look overly impressive at this time but should bring chances of more snow accumulations.

Looking pretty good over the next week so make sure to tune for the latest forecast!
