TLDR: Off/On light northern UT mountain snow showers through Fri. Expect 3-6” per day. Another possible northern UT storm Sun-Mon. Southern UT will get a significant storm with 18-30” for Brian Head/Eagle Point from Wed morning – Fri morning and 14-20” for the La Sal area Wed night-Fri morning.
Skiing conditions in the Wasatch are amazing right now with cold temperatures, clouds keeping the sun from impacting the recent snowfall, and a few passing mountain snow showers to give a refresh. Any caveats? You want to be above last Thu’s rain crust, or roughly 7.5K to 8.0K feet. Anonymous sources confirmed the above report in the Davis County backcountry today…or did they since they also reported not seeing another soul and did not take any photos?
The aforementioned “few passing snow showers” are the result of relatively moist northwest flow amid passing short wave troughs. Some of these appear to be enhanced by the Great Salt Lake as they pass overhead (see below image and note precipitation upstream of the lake but stronger precipitation over and downstream). It was showers like these that dropped ~2” at Alta from 3-4pm today and ~1-2” at Snowbasin from 10-11am. In both cases that appears to match the amount that fell during the remainder of the day.
Rest of the Week: Northern Utah can expect these showers to continue and roughly 3-6” per 24-hour period to fall through Sat. Thursday during the day should do a little better than that. The big news for across the state is Southern Utah will get hit with a strong low-pressure system. Precipitation will begin Wed morning for the southwest mountains and later in the day for the south-central and south-eastern mountains. Totals for Brian Head look very impressive, with 20-28” expected by that time (maybe more if everything comes together). Central and eastern areas should see 1-2”.
Extended Period: Some weather prediction models have a storm skirting to our north late Sat through Mon with decent snowfall for northern UT. However, there is a decent amount of uncertainty right now with this system so check back soon to see how strong we think it will be and if it is still on track to skirt or hit northern UT. See below for some of the possibilities.
