Summary

An extremely moist and abnormally warm weather pattern is in store for the Northern Rockies over the next 7 days. West of the Divide a series of spring disturbances, one Monday night, another on Wednesday, and yet another this weekend will bring tropical moisture streaming out of a westerly zonal flow delivering copious amounts of moisture along the Idaho border and to the resorts of NW Montana. Snow levels will start out tonight around 5500 and rise progressively through the week to around 8000’ by Wednesday night and Thursday. Look for Whitefish to add to their 17-day consecutive new snow streak with 4-8” of wet snow by tomorrow morning. East of the Divide the prognosis is the same, high snow levels but the moisture will be in much less amounts. Big Sky may see an inch or two each night but the skiing surface will mostly be of the spring variety all week.
