The same Western storm system which brought cold rain and mountain snow to Southern California and Arizona this past week will continue to bring additional snow and rain to the Midwest through tonight.

The storm's wintry mess across Minnesota and northern Wisconsin will gradually taper off for the balance of the weekend. Holiday shoppers and travelers in the region will notice improved conditions by Sunday.

The storm will prove more of a nuisance for the region with no major flight delays anticipated. Delays close to one hour in Chicago Saturday afternoon were blamed on low clouds.

The lack of cold air associated with this system will limit the extent of the wintry weather through tonight.

Snow from this storm will fall on some areas which were inundated from last weekend's potent storm system, but snowfall amounts will be significantly less.

As is the case with most winter storms, the heaviest snowfall will blanket areas northwest of the storm track. A swath of 1-3 inches across northern Minnesota will be the focus of some of the higher snowfall totals with a small swath of 3-6 inches.

Farther south, a periods of rain will wet areas from Chicago to Detroit and the Ohio Valley.

Cold and dry air will sweep in to most of the region on Sunday while a bit of rain and a few snow showers linger for a time as the system departs.

The storm system will begin to weaken as it crosses the Great Lakes and heads toward the Northeast Sunday and Monday.

Snow will spread into portions of southern Ontario, the St. Lawrence Valley and New England on Sunday.
