What can you say? It's that time of year! All week we have been watching the cold and snow affect others across the nation. Now it is our turn! Luckily, this snowfall does not look like a big deal, but the timing is not good as the Friday morning commute will be impacted.
As cold air from the west begins to shift east, a deep trough is shifting east. This is driving energy down into the Great Lakes which will link with moisture from the south, and allow a burst of accumulating snow to form over New England during the late evening and early morning hours of Friday. A low will track south of New England overnight and quickly pull away Friday morning directing much colder air into New England.
Precipitation will start off as a wet mix before quickly changing to snow across the interior. Meanwhile, along the coast and southeast MA. Showers may hold on longer, before changing over to snow in the early predawn hours. Here is a general overview of what the radar will look like this evening through early Friday morning for your planning purposes.
The heaviest burst of snow will form right over Metrowest, Merrimack Valley, Greater Boston between 5-7 AM, so please allow extra time for your commute tomorrow as travel will be slow with some roads becoming snow covered or slippery for a brief window of the day. Expect a widespread 1-2" snowfall during the early morning on Friday. There will be a few pockets of heavier snow inland which have the potential for seeing up to 3 inches, especially across parts of Worcester county in the hillier elevations. Another jackpot of snow is likely across the midcoast of Maine and up through Downeast Maine where there is a potential for up to 2-4+" of snow to fall before the snow ends around lunchtime for our northern neighbors.
A departing low will pull away Friday and wrap in cold dry air on the backside with clearing skies and cold temperatures. Highs on Friday in the Lwr 40's with breezy and brisk NW winds. Saturday will be even colder with highs in the 30's even with the sunshine. Stay warm!
