Another Cutoff Low

Posted Tuesday, March 16th, 2021 by CJ Sawyer

TL;DR: Warming and drying as we head through the week. A quick shot of precipitation is likely Friday night into Saturday.

Nowcast: Currently we have another cutoff low moving through Arizona with moisture being spun up on the north side of it.

This has primarily favored Southern Utah but showers have certainly moved through Northern Utah as well. Park City mountain resort managed to pick up around 11 inches last night in what was likely one of those shower bands.

Aside from that anomaly, most areas in the Wasatch picked up at most 4 inches.

Short term: As todays cutoff low moves off to the east, high pressure will gradually build in through the week. This will lead to a warming and drying trend with valley temperatures warming into the mid 60s by Thursday. Unfortunately for the mountain snow surface, that sun mean degradation on any aspect not heavily shaded.

Long term: Warm conditions through Friday with a strong cold front likely knocking on the door at that point. This could bring a quick shot of snow to the Wasatch for Saturday and Sunday. Beyond that, it is looking increasingly likely that we will be just downstream of ridging with no major storms as we head toward the end of March.
