Good morning! Quick update on tomorrow’s snow system.
Timing
Snow begins around midday Sunday. Heavy snow is possible at times throughout the afternoon and evening. Snow begins to wind down during the early stages of the Super Bowl, completely ending by (or just after) the end of the game.
Amounts
Expect a widespread 2-5″ of snow for northern Massachusetts and southern New Hampshire. If the current track of the system holds, this will be a fairly fluffy snow. Going further south, amounts increase to 5-8″ for much of the far southern tier of New England, but the weight of the snow also increases significantly the further south you go.
Uncertainty
The northern edge of the higher snow totals is in a little bit of flux. If we can get additional heavy banding to form locally, we could see several inches more than the current forecast due to the more favorable, colder air in this area (though the weight of the snow would probably be heavier locally than currently forecast if that does end up happening). However, it looks like the best dynamics will be confined to our south. There’s also a chance we could underperform the snow forecast if we end up closer to the northern edge of the overall snow shield than expected. This isn’t a super difficult forecast, however.
Impacts
While a significant (6″+) snow is not forecasted locally, this will still cause travel impacts with poor road conditions Sunday afternoon and evening. An in-person Super Bowl party with people outside your household is a really bad idea given the pandemic, but if you are traveling to watch the big game somewhere, take it slow as pregame will have the worst of the conditions. Maybe get your snacks and food today or tomorrow morning if possible. By the time Brady and Mahomes begin to square off, the snow should be starting to wind down.
Have a great day!
