Weekend Weather Spotlight: 11-19-21

We will be watching two systems affecting the country through the weekend. 

First, a system moves from the Northwest towards the Plains today and tonight producing rain and snow in the Pacific Northwest and the northern Rockies with several inches of snow possible in the Cascades, Bitterroots, Lewis Range, and the higher elevations in northwestern WY including Yellowstone. This system will pretty much fizzle out as it gets into a dry airmass in the Plains. 

The other system will be a trough that will move into the Great Lakes over the weekend. Initially, just some scattered rain and snow in the Dakotas and Upper Midwest as the airmass in this region will be fairly dry, but things begin to pick up Saturday evening and overnight into the Great Lakes as this system pulls up some richer type moisture from the south. This activity begins to increase in coverage in northern and central IL, southeast WI and IN and then will build east through the Northeast and Mid-Atlantic on Sunday. More scattered-type activity is expected further south into the Southeast and possibly as far west as the TX Gulf Coast. Much of the precipitation should be on the light side until Sunday evening and overnight from north-central FL to New England.
