Quiet Workweek, More on The Horizon

Posted Monday, December 2nd, 2019 by Eric McNamee

TL;DR: Pretty quiet over the next few days with a weak system making its way through Utah Wednesday/Thursday, mostly affecting the southern part of the state. Another storm moves in this weekend.

Currently, high clouds are streaming into the state with some showers along the Idaho border. These are associated with a trough affecting the Sierra’s and will bring us some snow Wednesday/Thursday.

Short-Term: As mentioned above, the trough bringing snowfall to the Sierrra’s right now will move into the interior west mid-week. The majority of the precipitation will stay in southern Utah, with the northern part of the state seeing some snow showers. Most resorts in northern Utah will see a few inches by Thursday. Mountains in Southern Utah will fair better and should see somewhere from 3-6″.

Long-Term: Conditions will clear out Thursday afternoon with a ridge building in behind the exiting trough. Heading into the weekend, an upper-level trough will dig in from the Pacific and bring us our next chance for snowfall across the state.

Snowfall amounts vary from model-to-model right now but a good amount of snow is possible.

Once we get closer to the weekend we should have a better idea of how much snow will fall. Until then, make sure to stay tuned!
