Monday Morning Mess?

While you’re enjoying a sunny Sunday, we’ve got some snow on the way tonight into Monday. It won’t be a lot, but it’ll probably make your morning drive to work into a large headache, especially south of Boston.

Low pressure will move out of the Ohio and Tennessee Valleys today and head east-northeastward, passing south of New England Monday morning. For once this season, we have enough cold air in place and a favorable storm track that we’ll be talking about all snow with this system, except possibly across parts of Cape Cod and the Islands. Since this is a fairly weak storm, we’re not talking about a lot of snow to begin with, and with it passing well to the south, the amounts will taper off quickly, the farther north you go.

The high resolution NAM model has a pretty good handle on how this storm will go, on our opinion. Loop provided by Tropical Tidbits.

The snow will develop late this evening from west to east, roughly in the 10pm-midnight time frame. It will continue through the overnight hours, and may even be briefly moderate to heavy south of Boston. While the steadiest snow looks to end during the morning hours on Monday, occasional light snow and snow showers will continue off an on during the afternoon, especially along the coastline. Everything should be done by evening.

So, how much are we looking at?
Southern NH/Southern ME: 1″ or less
Merrimack Valley: 1-2″
North Shore/Metro West: 1-3″
I-95 Corridor (Boston/Providence): 2-4″
Southeastern Mass/Southern RI: 3-6″, possibly a little more across Cape Cod

We’ve stuck with the high-resolution NAM for much of the winter, and it’s done pretty good, so we see no reason to go against it now. Image provided by WeatherBell.

Another storm may bring in more snow towards Wednesday, but we’ll have more details on that in our Weekly Outlook early Monday.
