Last night 3-4 inches of snow fell in the Bridger Range, northern Gallatin Range and around Cooke City, while two inches are reported around Big Sky and a trace to an inch everywhere else. Winds are averaging 25 mph of the N-NW with gusts of 40-50 mph. Under cloudy skies mountain temperatures are in the mid to upper teens. Today, winds will become moderate under mostly cloudy skies.

This morning mountain temperatures are 20F with W-NW winds blowing 15-20 mph under clear skies. Today will be mostly sunny and winds will increase with daytime highs reaching the low 30s. A cold front and moist northwest flow are teaming up late tonight bringing snow through tomorrow. By morning, I expect 2-4 inches with much more falling Wednesday. My fingers are crossed that the northwest flow will wring even more snow onto the Bridger Range.

Winds are currently blowing 10-20 mph out of the west to northwest except in Cooke City where they are much stronger and gusting to 35 mph. Today will warm into the upper 30s with moderate winds. High pressure will block any chance of precipitation and sunny spring-like weather is forecasted tomorrow. The big question is, do I keep my snow shovel on my porch or my skateboard?
