A series of weaker systems out ahead of the main storm off the Northern California Coast will keep mostly valley rain, and mountain snow going through Thursday.
Snow elevations will bounce around from as low as around 5,000 feet to as high as 6,500 feet. Amounts will range from a few 0.10”s of rain in the valleys to a few inches in the mountains.
Look for amounts on the order of 1”-3” for Park City and Snowbasin tonight and 3”-6” for Alta, Snowbird, and Brighton. Double those going into Friday morning.
As the storm moves through Utah on Friday, colder air will pool into the region changing the rain to all snow for everyone in Northern Utah. Salt Lake City could find a few inches of snow on the ground by Friday evening and that could mean roads might be an issue on the afternoon/evening drive on Friday.
MUCH colder air continues to rush into the region over the weekend as high temperatures will only top out around freezing in Salt Lake City on Saturday and Sunday with a few lingering snow showers possible too. Morning Lows could drop to as cold as single digits and teens by Sunday and Monday morning!
Final storm totals for the mountains could reach up to around 3 feet for the Big and Little Cottonwood Canyon resorts and upwards of a foot to more in Park City and Snowbasin. Brian Head could find storm totals of 2 feet to possibly upwards of 3 feet.
