Winter Weather in Great Salt Lake Desert and Mountains, Utah

Snow Squall. Multiple mesonet stations recorded periods of strong wind gusts (multiple periods in excess of 30 mph) and significant reductions to visibility as a well defined band of snow moved into the area, and gradually began to fall apart as the evening progressed. Some examples include the I-80 @ Grassey mesonet site (peak wind gust of 43 mph, visibility below 1/2 of a mile), the I-80 at MP 68 West Delle mesonet site (peak wind gust of 43 mph, visibility below 1/2 of a mile), and the I-80 @ mp 1 mesonet site (peak wind gust of 43 mph, visibility of 1/2 of a mile). Many of these mesonet sites also reported temperatures rapidly falling below freezing as this snow squall passed.

Snow squalls developed and moved southward through northern Utah during the evening hours on both January 9 and January 10, bringing impacts to the evening commutes. Utah Highway Patrol reportedly responded to 101 vehicle accidents on 1/9, and 143 vehicle accidents on 1/10. A portion of these will be included in rough event damage estimates. Surprisingly, no injuries were reported with these accidents.
