Welcome to the weekend! It will bring a lot of cloud cover and temperatures won’t move all that much staying mainly in the 30s. Dry today. Then tomorrow morning rain and snow arrives continuing into Monday.
A Winter Storm Watch has been expanded to include areas within I-495 and southern Worcester County. It currently encompasses Worcester and northern Middlesex, Essex counties and the eastern slopes of the Berkshires. This runs Sunday through Monday morning for the potential for heavy snow that could create difficult travel.
Here’s a look at the snowfall accumulations Sunday evening through Monday morning.
You can see the moisture for part of our storm across the South. That area of low pressure will track inland, forming another area of low pressure near the coast. It’s that one that will bring us rain and snow.
Here’s a closer look at the timing of the storm. This will be a snow event for areas north and west of I-495, a mix for MetroWest and rain turning to snow at the end for Southeast Mass. Snow and rain arrives tomorrow morning filling in from south to north. There will be a mix along the coast where there will be milder air initially with an onshore wind. Later in the day, snowfall amounts will still be on the lighter end anywhere from a coating to 2″ (the higher end of that the farther you are away from the coast). Late Sunday into Monday, the rain/snow line slips south, as the wind shifts and colder air above us starts to work in. This will end as snow showers for everyone Monday. Expect a slow Monday morning commute with scattered snow showers. The snow tapers but likely lingers later in the day for Plymouth County and Cape Cod.
Here’s a closer look at the snowfall amounts for your town by Monday morning.
The storm will also kick up the wind. It’ll be breezy Sunday, and the wind peaks Monday. Gusts will be strongest on Cape Cod, Cape Ann and Nantucket. The heavy snow and wind gusts along and north of I-495 into northern Worcester County and northern Middlesex County could lead to a low risk for power outages. There isn’t a concern for coastal flooding with this storm.
Temperatures stay cold Monday and Tuesday. We’ll get the sunshine back Tuesday! As of now, the rest of the 7-day forecast looks fairly quiet. There’s a chance for rain and snow to return to the area by the end of the week.
