Summary:

Snow showers will spread into northern Utah from the south today with relatively high snow levels.  The flow switches to the west then northwest on Monday night into Tuesday as a reinforcing and much colder wave moves in bringing more snow.  Dry weather for late this week into the weekend.

Details:

Closed low off the California coast has been nearly stationary and has but funneling moisture into southwestern Utah all night.  Brian Head reporting an additional 14" of heavy, wet snow. That brings their storm total to 37"!!!  They should see another 6-12" today as the moisture shows no signs of abating.  This moisture is just making its way into the Wasatch.  Eagle Point which is in Central Utah has received another 8" of snow.  Around Salt Lake and PC, resorts just getting 1-2".  Showers should continue through today with a few more inches possible by evening.

Tonight, the low should finally start moving east while at the same time a cold wave moves in from the northwest.  This should switch the flow from southerly to westerly and eventually northwesterly by early Tuesday morning.  Generally expect snow to increase tonight in Northern Utah. Tomorrow could be very good for places like the Cottonwoods with a favorable northwest flow.  6-12" by Tuesday evening with perhaps more (up to 18") in the Cottonwoods.  Tuesday could feature very good storm day skiing/riding!

By Wednesday we clear out and start to warm up as high pressure moves back into the area.

Long range:

Not much good news I'm afraid.  We had our pattern change and it brought us 10 days of very active weather. It looks like we are about to enter a 10-day cycle of mostly dry and warm weather.  Unfortunately, while the Wasatch saw several storms recently, we didn't get any BIG storms during this pattern change.  Southern Utah seemed to be favored each time.  Brian Head will likely have seen close to 70" of snow in 10 days once this storm wraps up.

Looking ahead we have slight chance for a few showers on Saturday the 7th.... Long range models keep pushing back the return of storms.  A few days ago it was the 10th, now it looks more like the 14th... Needless to say, not much confidence in the long range.  March will start off right with some snow today and tomorrow, so go enjoy it while it's here!

P.S.  Because the low has been so stationary, the forecast for insane snow in the San Juans isn't really verifying.  They'll be getting their snow later today and tonight, but I doubt anybody will come close to the 8" of QPF that models were forecasting a few days ago.  Still, I'm in Telluride and we've received 27" since Friday on the upper mountain, can't complain too much.
