Friday's Pinpoint Forecast: WINTER STORM WARNING for most of Utah on Saturday. Tonight will not be as cold, cloud cover will keep most locations in the 0s and 10s, but the Uinta Basin will drop to around -10. Saturday, snow will develop through the morning hours across the state. Because of the recently cold temperatures, snow will quickly accumulate on all road surfaces, even down to St. George. Accumulation will generally be between 2-6" in most of the lower elevations, but the southwest mountains could see around 12". Temperatures will be cold, mainly in the 10s and 20s for highs. Saturday night, as the low pressure moves away, it will pull some renewed frigid air across the Great Salt Lake. Lake Effect snow will likely develop, and could push snow totals up to 18" around Davis and Salt Lake Counties, and the surrounding Wasatch mountains. The lake effect could wind down by Sunday afternoon. Sunday will be partly cloudy and cold across the state, with most highs in the 10s, 0s and -0s in the mountains, and 20s to near 30 for the lower elevations of southern UT. Sunday night will be bitterly cold again, with arctic high pressure reestablishing itself over Utah. Most locations will drop below zero, and some places will fall to -15 to -30 again! Next week, temperatures will slowly moderate, but a developing inversion will mean pollution getting trapped along the Wasatch Front, so by midweek, the air quality will deteriorate.
Be safe this weekend, and enjoy the snow!
