Warm conditions today thru Friday before a major change takes place for the weekend with a cold trough bringing snowfall to Utah mountains (and perhaps valleys). This could be one of our last opportunities for powder.
Apologize for the late post today — been feeling a bit under the weather and decided to sleep in. Speaking of weather, today will be much warmer than yesterday as high pressure is taking control. Another big jump tomorrow in our temperatures up into the 70s in the valleys and 50s on the mountain. Winds will pick up on Friday ahead of the big change we’ve been watching.
The storm will push into the far north along the Idaho border on Friday night. The front could stall there and bring heavy precip to far northern Utah and southeast Idaho. Eventually, the system will dig into the region on Saturday with snow developing during the day in the Central Wasatch. Snow should continue into Saturday night with snow showers continuing through Sunday in a cold northwest flow. At this point, it looks like a last chair Saturday, first chair Sunday type of weekend.
Cold air will also move into the area with snow levels likely dropping down below 5000 feet. Probably down to most valley floors late on Saturday. Accumulations will likely be confined to cold surfaces (grass/dirt/etc).
As for snowfall totals in the mountains, we are starting to see a little bit move agreement in the models and their ensembles:
Totals generally ranging from 1-3″ of liquid. I would guess the high end of this is overdone, so let’s adjust this to 0.75-2″ of liquid. I think we are looking at 1-2 feet of snow for favored locations with 8-16″ elsewhere. The Cottonwoods could do well in the NW flow on Sunday. We will gradually clear out on Monday with a few weak disturbances passing through.
Generally, next week looks dry after the weekend storm. A dirty ridge will be in place which means weak systems may just pass to our north. It does look like we could see a return to more active weather around mid-month. We’ll have to keep an eye on that.
