A quick blast of winter weather overnight tonight and lingering through early afternoon for the eastern highlands and western Wyoming will be the first storm to give us some travel concerns for the holiday weekend. Snow begins for the valley around 7am tomorrow morning along the I-15 corridor, and tracks quickly east, ending after a dusting to possible 1″+ for mountain ridges, and western Wyoming. Freezing conditions overnight from 18 in Jackson to 20’s in the valley will create visibility hazards and slick roads early. We take a break from snow during the afternoon tomorrow and then have some cloudy, dreary conditions on Sunday – with the exception of snow/slush continuing for upper highland areas into Sunday morning, especially areas north of Rexburg and around Island Park, adding to any previous snow totals.
Snow chances are 60% into late Sunday and Monday morning for Idaho Falls, and will make for a sloppy morning return to school and work. After which, a major blast of arctic air takes over and it will feel like the north pole sent a message to gather up any available reindeer for backup during this winter.
Tomorrow: AM snow 1-2″ and more along mountain passes to Wyoming/Montana
26° in the morning/33° in the afternoon
Saturday night: Mostly cloudy, cold and frozen 22°
Sunday: Mostly cloudy 35°, with winds picking up SW 10-25+
Sunday night: Mostly cloudy – 50% chance of snow late – 26°
Monday: Snowy/cloudy – get an early start – 31°
