|Western Atlantic surface map, 7:00 EST March 7|
In the west an upper level system will come ashore in southern California early Friday heading toward the southern Rockies. Rain and snow will accompany this system as it makes its way across the Southwest, and winter weather advisories, watches, and warnings are in effect for a number of western states. This southern system will merge with another disturbance in the Northern Plains, and by Saturday morning will be bringing snow to a large portion of the central and southern Rockies and the Northern Plains. Ahead of this system, strong southerly winds will feed moisture to fuel showers and thunderstorms eastward through the Midwest.
