Potential for Snow Across Portions of the Northern Plains on Wednesday
A mix of rain and snow is forecast on Wednesday as a weak disturbance moves across the region.

A Look Ahead
Snow is forecast over the higher elevations of the Northern Rockies Friday as an area of low pressure develops over the Pacific Northwest. This snow should move out of the Rockies and into the High Plains on Saturday. A cold front moving into Northern California on Saturday may bring some light rain to the region. By Sunday, a rain/snow mix may impact portions of the Upper Midwest.
