It seems as though we are getting a snowstorm after all tomorrow. It won’t be a big one, or a long-duration one, but it will impact your Sunday.
At the end of our Weekend Outlook, we mentioned the chance for snow on Sunday, but closed with this:
“Overall, not a big deal for most of us. Parts of the South Coast could see a few inches of snow depending on how far north the ocean storm actually gets, but otherwise, we’re not anticipating much accumulation across the region, unless things change in the next day or two.”
Well, things have changed. Low pressure will move off the Mid-Atlantic coastline tonight, and pass south and east of Nantucket on Sunday, farther north than we were thinking on Thursday. This will result in accumulating snow for most of the region, with this ending up as a moderate snowstorm far parts of southeastern Massachusetts.
Snow will develop from southwest to northeast during the morning, and from late morning into mid-afternoon, snow may be moderate to heavy at times, with snowfall rates of 1 inch per hour or more. The snow will start to wind down by late afternoon or early evening, just in time for the Super Bowl to begin. For most of us, this will be just a snow storm. However, for parts of Cape Cod and the Islands, there is a chance that some sleet or rain could mix in, which would keep accumulations down slightly.
So, how much are we expecting?
Central NH (Manchester/Concord): 2-4″
Southern NH/North-Central MA: 3-5″
NH Seacoast/Merrimack Valley: 4-7″
The Rest of Eastern MA/RI: 5-9″, except 3-6″ across the Outer Cape and Islands and the immediate east coast of MA
As was pointed out to us by a colleague for parts of Southeastern Massachusetts, this will be one of the biggest storms this area has seen in a few years. Using Middleboro as an example. they have only received 6 or more inches from a single storm twice in the last 3 years – 6.5″ December 2-3, 2019, and 8.5″ on March 4, 2019.
Beyond this, our next chance for some snow will be with another weak system on Tuesday. That storm will produce a little light snow, possibly rain south of Boston. However, given the performance of the models more than a day or two out, would you really be surprised if it becomes something bigger? We’ll have more on that in our Weekly Outlook Monday morning.
