A weak boundary will move into far northern Utah tonight into tomorrow with light mountain snowfall (1-5″). A break on Monday and Tuesday. Next system moves into Utah early Wednesday with high mountain snowfall likely.
Another dirty ridge day today will keep us dry but cloudy at times with breezy conditions. A cold front boundary is already starting to sag south and that will move into far northern Utah tonight and reach SLC area by tomorrow morning. This weak boundary does not have a great amount of moisture and dynamics associated with it, but it should at least spark some valley rain and mountain snow showers. Here is a QPF map for tomorrow from the NAM model:
You can see that precip only extends as far south as the Cottonwoods and is pretty meager. The best event should be up near Beaver Mountain and the Idaho border where 6-12″ is possible. But in the Central Wasatch, I’d say 1-3″ is more likely with up to 5″ if one lucky place gets under a persistent band of snow tomorrow. Nothing even close to significant, but could freshen up your turns a bit.
We see a break on Monday and Tuesday with temperatures warming again well above normal.
Next trough moves across the Great Basin Tuesday night and arrives in our area by Wednesday morning. This system has a southwest to northeast trajectory which isn’t our most favorable. It also has warmer-than-normal air so snow levels should be above 7,000 feet for much of the event. At this point I’d say accumulations Wednesday and Thursday will likely only be in the 4-8″ range, but there’s plenty of time for these details to change.
It looks like a few showers might linger in the area into next weekend, but no significant storms are in the long range. Generally, models have favored ridging for the second week of December, and until I see otherwise, that’s the going forecast.
