Snow for the Northern Rockies and Plains Friday through Early Sunday
An upper level disturbance moving into the Pacific Northwest will allow a surface low to intensify over portions of Idaho and Wyoming. The upper level trough will enhance lift and moisture near a stalled front along the Idaho/Montana border with precipitation increasing early Friday into Saturday. Snow accumulations of 3-6 inches are expected in the lower elevations with locally higher amounts in excess of 8 inches. Above 5,000 feet, 8-12 inches with locally higher amounts in excess of 14 inches are forecast. Precipitation will come to an end by Saturday evening as an area of low pressure moves eastward. Across Northern and Central Montana into portions of the Northern Plains, snow accumulations of 2-4 inches with locally higher amounts in excess of 5 inches are forecast through early Sunday.

A Look Ahead
There will be a threat for strong to severe thunderstorms on Sunday across the Great Lakes region. With a surface low and its associated fronts tracking eastward from the Central Plains and Midwest into the Great Lakes on Sunday, instability will build out ahead of the area of low pressure's associated cold front across portions of the Midwest and Great Lakes. With this instability in place, in addition to ample low level moisture and strong wind shear, scattered showers and thunderstorms will develop during the afternoon and evening. Some of these thunderstorms could become strong to severe in nature. At this time, large hail, damaging winds, and tornadoes will all be potential hazards. The threat will transition to a primarily damaging wind threat by the evening hours on Sunday.
