Wind event tips: A thread— Utah Division of Emergency Management (Utah DEM) (@UtahEmergency) September 8, 2020
If winds materialize like @NWSSaltLakeCity and other meteorologists are saying, Weber, Davis and Salt Lake residents could be in for a mess tonight.
Here’s what we leaned from a similar wind event in 2011.
The storm will bring a cold front and temperatures are expected to drop by around 26 degrees across Utah, with near-blizzard conditions across the Uintah Mountains and snow expected for the Wasatch Plateau and southwest Wyoming.
The National Weather Service confirmed that record-low temperatures are expected Tuesday through Wednesday with the wind and a hard freeze is expected for vegetation. Monday night through Wednesday, mountain rain and valley snow are forecast with strong probability, though some uncertainty remains on the precipitation type, amount, and duration. Rain is likely in all locations to start, including lower areas of western Colorado and possibly eastern Utah, the NWS’s Situation Report states. Snow is probable in areas above 9,000 feet, and may mix in at elevations of 7,000 feet.
Downslope windstorms occur when cold, dense air is pushed against a slope, creating an accelerating, and sometimes dangerous, wind at the bottom, opposite side of the slope. In Utah, the cold, dense air is on the east side of the Wasatch mountains, according to the NWS.
