More snow on the way

Posted Sunday, January 3rd, 2021 by Brittany Whitlam

TL;DR: Another storm will bring more snow for the Wasatch tomorrow night into Tuesday morning. Beyond that, conditions are not looking great for any major storms to bring us the snow we desperately need. 

Nowcast: Flakes are flying in Wasatch this morning as a storm system associated with a shortwave trough located to our north passes through. Accumulations have been light, totaling around an inch so far for resorts in the Cottonwoods. Winds are gusting to 20-30 mph at the mountain crests with temperatures in the upper teens.

Short Term:  Light snow will continue in the upper elevations through this evening. Ridging will briefly fill in tonight, cutting off moisture this evening into tomorrow morning. A stronger, more potent shortwave will dig through northern Utah tomorrow night.

This system will kick off snow showers late Monday night and will continue through Tuesday morning. Around 3-8 inches are expected for most locations in the Wasatch with this storm.

Long Term: Ridging will build in again behind Tuesday’s storm, keeping conditions dry through midweek.  Another shortwave is expected to pass through northern Utah on Thursday, but chances for notable precipitation remain low at this time. Overall, conditions are not looking conducive for any major storms through mid-January. However, we’re still a long way out from there, so keep your hopes high. We’re in this together!
