Utah forecast: Wintry, windy weather in north, sunny in the south
A Winter Weather Advisory was in place Wednesday for the northern Wasatch and western Uinta mountains, where up to a foot of wind-driven new snowfall was expected overnight.
The advisory area stretched from Logan south through the mountains of Ogden, Salt Lake City and Provo to Nephi, as well as the area of the Mirror Lake Highway into Wyoming. By early Wednesday afternoon, heavy snowfall was blanketing the valleys of northern Utah.
The advisory was to expire at 10 p.m. Wednesday.
Heavy snow, in places whipped by winds of 65 mph and more, especially targeted Interstate 80 through Parleys Canyon, and Highway 89 through the state's northern mountains.
The Utah Avalanche Center rated the risk for potentially deadly backcountry snowslides as "high" in the Uintas, while the Logan Ogden, Salt Lake, Provo and Moab districts had "considerable" avalanche danger grades going into Thursday.
The National Weather Service also issued a High Wind Warning for the northwest quarter of the state through 7 p.m. Wednesday. Winds of 35-40 mph, with gusts above 60 mph, were expected during the period.
In the Salt Lake and Tooele valleys, stiff breezes in the 20-30 mph range also were expected Wednesday, giving way to calmer conditions on Thursday. High temperatures on Thursday were to climb only into the upper-30s, a few degrees warmer than on Wednesday.
Southern Utahns expected milder breezes, but mostly clear skies and highs in the mid-60s.
The Utah Division of Air Quality rated breathability statewide in the "green," or healthy category.
