Snow and rain showers spread across the Upper Midwest and Great Lakes on Friday, while heavy rain showers returned to the Pacific Northwest.

A low pressure system continued to move eastward over the Great Lakes and into eastern Canada. Counterclockwise flow around this system continued to push a cold front eastward, which moved over the Ohio River Valley and into the Northeast. This front produced scattered rain showers throughout the day as temperatures remained in the 50s.

However, the back side of the low pulled cold air in from Canada, which allowed for snow showers to develop from Minnesota, through Michigan, and into the Northeast behind the cold front. Lake effect snow showers developed along downwind shores, as flow over the lakes picked up additional moisture.

This allowed for some areas to see up to 6 inches of new snow, while most areas from Minnesota through western New York saw around 2 inches of snow. Strong and gusty winds also spread across the region with gusts from 40 to 50 mph.

Meanwhile in the West, a low pressure system spinning in the Gulf of Alaska pushed another trough of low pressure and associated cold front into the Pacific Northwest. This produced heavy rain showers across western Washington and Oregon, with midday rainfall totals surpassing 1 inch.

Heaviest rainfall was reported in Shelton, Wash., with a midday total of 1.36 inches. As moisture from this system reached inland, cooler temperatures in the mountains allowed for rain to turn to snow showers. Winter weather advisories have been issued for parts of the northern Washington Cascades as snowfall accumulation from 3 to 7 inches were anticipated.

In the Plains, while high pressure kept most of the Central and Southern Plains sunny and dry, showers and thunderstorms developed over southern Texas. Severe storms have not developed in the region.
