Winter Weather in Eastern Box Elder County, Utah

Snow Squall. Multiple mesonet stations recorded a period of moderate wind gusts (generally 20 to 30 mph), and significant reductions to visibility (at times 1/4 of a mile or less) as a band of heavy snow moved through the area. Some selected mesonet sensors with supporting observations include the I-15 @ Tremonton mesonet site (peak wind gust of 27 mph, visibility to 1/4 of a mile, snowfall rates of 2 inches per hour), the I-15 at MP 369 North Brigham City mesonet site (peak wind gust of 23 mph, visibility to 1/4 of a mile), and the I-15 @ Willard POE mesonet site (peak wind gust of 31 mph, visibility to less than a quarter 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.
