Weekend Weather Spotlight: 12-16-22

A storm system that has been tracking across the country throughout the past week will continue to affect parts of the country for the next couple of days with more widespread rain and snow.

First, a surface low will be located in the vicinity of NJ early today and will track northeast getting to around Boston by Saturday morning and then getting into the New Brunswick and Nova Scotia region of eastern Canada throughout Saturday. Widespread rain is expected for areas closer to the coast with a brief change over to snow before ending including places like NYC, Providence, and Boston. Further west and north through the rest of New England widespread accumulating snows are likely with 6-12 inches possible with locally heavier amounts, and higher amounts possibly approaching 2 feet in some of the higher elevations. 

Further west into the Eastern Great Lakes another lake-effect snow event is probable as west-southwest winds develop this evening and will result in several inches of snow for southeast NY including Buffalo once again. Snow showers are expected fourth down the lakeshore of Lake Erie to near Cleveland, OH with lesser amounts mainly around a couple of inches possible for northeast OH and northwest PA. 

Now to the western extent of this system, another low will continue to spin in MN, WI, and the UP of MI today and eventually gets into Canada early in the day on Saturday. This system will have the potential to produce additional accumulations of 1-4 inches from the eastern Dakotas to lower MI with locally higher amounts possible, especially in the western part of the UP of MI and western lower MI where winds off these lakes will enhance and prolong snow shower activity. 

Finally, another trough builds into the Northern Rockies over the weekend bringing snow showers from WA to ND a few inches possibly mostly affecting areas along and north of I-90 and I-94. Locally higher amounts will be possible in higher elevations.
