Weekend Weather Spotlight: 11-13-20

The Pacific Northwest will be active through the weekend with heavy rain and snow, and a system develops in the central US producing rain and snow.

First, in the Pacific Northwest, a series of systems affect this region through the weekend with heavy rain accumulating in the 3 to 6-inch range in western WA, western OR, and northwest CA. Heavy snow is expected in the Cascades of WA and OR with over 3 feet possible, and several inches of snow will fall further east in the mountainous regions of ID, eastern OR, northern NV, and central and northern Rockies. 

Further east a low-pressure system is expected to develop beginning as early as late tonight in the central Plains but then intensifies in IA on Saturday as it continues to head northeast through the GHreat Lakes Saturday night and into Canada overnight Saturday into Sunday. Scattered showers and storms initially develop this evening and overnight from central TX to central MO, then increase in coverage over the weekend as this activity heads east ahead of a cold front affecting the Mid Mississippi River Valley and Ozarks Saturday afternoon/evening, Ohio river valley Saturday evening through midday Sunday, and then into the Mid-Atlantic and Northeast Sunday evening and overnight. Closer to the low center precipitation will begin as rain or a rain/snow mix, then a gradual changeover to snow will occur Saturday evening and overnight beginning in MN and continues east into northern and central WI, the UP of MI, and northern lower MI. An inch or two of snow is possible in these areas with the potential for more in the favorable lake effect snow belts off Lake Superior and Lake Michigan.
