Snow or rain/snow mix should be tapering off in the afternoon. Afternoon temps in the mid-30s may make for a slushy mess on grass surfaces. By evening, clouds should start clearing, but temperatures will be falling. Looking for a kickoff temperature of 31 F falling into the mid-20s by the 4th Q. Wind NW at 10 mph, decreasing gradually during the evening. Wind chills around 20.
Valley temps (along I-15) should remain above freezing so don’t see a big travel problem. Rain/snow mix and wet roads, mainly north of Cedar City, may slow traffic however. Have a safe trip.
