Weekend Weather Spotlight: 12-18-20

A wavy upper pattern will be in place across the northern part of the country the next few days resulting in a series of weak low-pressure systems tracking mainly through Canada, and no major systems are anticipated. 

First, a system will move across the eastern half of the country with the main low moving through Canada, but a cold front will drape well south to the Gulf. On the northern part of this front will be mainly light snow potential with an inch of accumulation possible across northern MN, northern WI, and the UP of MI today and tonight and lower MI on Saturday. The front moves into a region of higher moisture on Saturday night when 1 to 4 inches of snow could occur from north-central IN to southeast lower MI and lighter amounts of around an inch are still possible into parts of New England on Sunday. Further south around the front precipitation will be fairly spotty and light until late tonight into early Saturday when showers increase in coverage with a few embedded storms possible from east TX to western AR. This area of showers and possible storms will move east through the weekend with heavy rain possible from east TX to southwest IN throughout Saturday, from central KY to the FL panhandle overnight Saturday, and into the Carolinas early on Sunday. Showers and possible storms are expected to become more isolated or scattered throughout Sunday.

The next low will have minimal effects mainly to northern Mn and northwest WI with a chance for up to an inch of snow Sunday evening through Monday morning. 

Finally, this upper-level pattern will favor an active stretch of rain and snow in the Pacific Northwest with several inches of snow accumulations for the Cascades and northern Rockies.
