On the backside of a surface low moving along the Northeast, cold air will stream into the Lower Great Lakes region, creating light to moderate lake effect snow on Saturday and Saturday night. Another surface low pressure system will move eastward through the Northern Plains on Saturday and into the Upper Great Lakes on Sunday. This will lead to snow of 1 to 4 inches in the Northern Rockies and parts of the Northern Plains on Saturday, and lake enhancement will help create snow downwind of the Upper Great Lakes this weekend as well. An upper-level trough is forecast to strengthen in the Four Corners region, and a cold front will pass through the Southern High Plains on Sunday. These features will help create a snow event for the Central and Southern Rockies and Plains on Sunday and Sunday night.
