This week started with a decent storm that dropped up to 5-7 inches of snow containing a lot of water. Another 2-5 inches of snow fell Tuesday night, and some places were dusted Wednesday night. At most upper elevation SNOTEL sites, the snowpack has reached its peak water content which should start quickly going down in coming weeks.
In the springtime battle between winter and summer, it seems like summer is starting to win more lately…but last year the final snowfall in Bozeman was on June 17th.
Temperatures - Air temperatures in the mountains dipped below freezing Tuesday and Wednesday nights. Last night (Thursday night), low temps were on either side of freezing, but clear skies should have helped refreeze the snowpack a little but.
This weekend and early next week - An upper level ridge of high pressure will bring warm, sunny weather today, Saturday, and Sunday morning. Clouds and rain arrive Sunday afternoon, but cold air doesn’t arrive until Monday morning with winds from the north that shift to northeast and east. Snow should fall Monday morning through Tuesday morning. Most places should only get an inch or two of snow, but there may be isolated spots (Tobacco Root Mtns maybe?) that could get 5-8 inches.
