NOAA has placed a winter weather advisory early this morning for the Northern Wasatch region in Utah. Snow has increased to a steady rate, and is expected to become heavy this afternoon in the mountains of Northern Utah. The region is expected to get up to a foot of fresh snow in the next 24 hours.
Precipitation will slowly spread south late today and tonight through the entire state with snow above 6,000 feet. Mountain accumulations should be in the 6-12″ range, with up to 15″ possible in favored locations like the upper Cottonwoods.
A reporter at Wasatch Snow Forecast calls this a “bowling ball” system. “This QPF map shows the relatively narrow corridor that this bowling ball is taking from Northern Oregon and Washington state, heading southeast directly through Utah on it’s way to New Mexico. The San Juans of southwestern Colorado should get nailed as well! Strike!”
The winter weather advisory is in effect until 11am MST on Tuesday.
