Weekend Weather Spotlight: 12-3-21

The jet stream will be draped across the northern part of the country through the weekend where we will find a few systems tracking producing rain and snow. 

First, a system will continue to exit eastern Canada today, so just a few lingering light snow showers in parts of New England early today.

Next, a system will move from central Manitoba, Canada eastward through southeastern Canada producing mainly light precipitation in the Great lakes today/tonight and New England Saturday/Saturday night.

Finally, the much more significant system over the weekend will get going in the Pacific Northwest late tonight and early Saturday and will have the potential of producing some heavy rain and snow. Several inches of snow over 4 inches will be possible in the northern Cascades, northern Rockies, and areas mainly north of I-94 from eastern MT to southeast WI with the best chances coming in northeast ND, northern MN, northern WI, and the UP of MI. As this system gets further east on Sunday mainly rain will be expected from the Mid and southern MS River Valley northeast to New England. Low-level flow in these regions increases and will result in some of the rain becoming heavy at times. Rainfall amounts over an inch are possible from southeast OK to western OH, and a few areas from northern AR to western KY could get over 2 inches.
