Rain Mixed With Wet Snow Expected Late Tonight Through Tuesday Morning Across Western & Central Mass

For This Afternoon: An area of low pressure is expected to track well to the southeast of Nantucket later this afternoon. This storm’s track is a bit further east than what was thought at this time yesterday. Because of this, it looks likely that steady rain will have a tough time pushing westward into Central and especially Western Mass this afternoon.

So, for this afternoon, I think that we will see some scattered rain shower activity with high temperatures between 35 and 40 Degrees. North winds will gust up to 25 mph at times this afternoon.

Tonight: That low pressure system is expected to track towards Atlantic Canada tonight. At the same time this is happening, a robust piece of atmospheric energy will move into southern New England late tonight. This piece of energy will bring with it steady precipitation that will move into Western Mass after about 2-3 am tonight.

The precipitation type late tonight looks to be rain across Western Mass, however, some areas of freezing rain is a possibility across the Berkshires.

This area of steady rain will push into Central Mass by about 5-6 am Tuesday morning.

Low temperatures tonight will be in the low to mid 30s.

Tuesday: That strong piece of energy will continue to push through southern New England during Tuesday.

The part of the weather forecast that is most certain is that steady precipitation will occur on Tuesday morning across a large part of Western and Central Mass. This precipitation will end by midday Tuesday.

The much more uncertain part of the weather forecast is whether the rain will mix with or change to snow across parts of Western and Central Mass on Tuesday morning. Colder air will be trying to push into southern New England during Tuesday, however, the forcing for the cold air to push into our area isn’t all that strong. In addition, temperatures on Tuesday morning will likely be in the 33 to 37 Degree range across Western and Central Mass.

I think that we will probably see rain mix with wet snow across Western Mass into northern Worcester County throughout Tuesday morning. Mostly all rain is expected on Tuesday morning across southern Worcester County. Given that the push of colder air is not very strong & will be slow to occur, snow amounts of up to one inch is possible in the higher elevations of Western Mass and northern Worcester County and a slushy coating on non-pavement surfaces is expected in the lower elevations.

All-in-all, roads and highways likely will remain wet on Tuesday morning as any wet snow will melt on pavement surfaces.

High temperatures Tuesday afternoon will be between 40 and 45 Degrees.

Wednesday: An area of low pressure is expected to develop well to the south of Long Island and pass well east of Nantucket during Wednesday.

Even though most of Western and Central Mass will be dry, but cloudy on Wednesday, some isolated rain showers are possible on Wednesday.

High temperatures Wednesday will be between 40 and 45 Degrees.

Thursday: Thursday is expected to be a partly sunny day with high temperatures between 45 and 50 Degrees.

Friday: A cold front is expected to push across southern New England during Friday afternoon bringing with it some scattered rain shower activity.

Friday looks to be the warmest day of this week with high temperatures between 50 and 55 Degrees.

Once that cold front moves through, temperatures are likely to fall into the 20s during Friday night. In addition, northwest winds gusting up to 35 mph will lead to Wind Chill temperatures in the teens during Friday night.

Saturday Through Sunday: An area of high pressure will give the region a sunny day on Saturday with high temperatures between 40 and 45 Degrees.

I am keeping an eye on the forecast evolution and track of a low pressure system that will be moving off of the Mid-Atlantic coastline on Saturday night. The weather forecast guidance that I look at have differing “opinions” on how far north this storm may track.

Some guidance forecasts a track well to the southeast of Nantucket which would mean a dry, but cloudy skies on Saturday night and Sunday. Other forecast guidance shows a storm track that takes this low pressure system right across southern New England which would lead to rain across Western and Central Mass on Saturday night and Sunday morning.

At this point, I’m thinking that we may see this low pressure system track near Nantucket late Saturday night and Sunday morning. This would be close enough for some rain to occur on Saturday night and Sunday morning in the Pioneer Valley of Western Mass and the Blackstone Valley of Central Mass & for the possibility of either a rain-snow mix or all snow to occur in the Hilltowns of Western Mass and across the Worcester Hills.

It’s a system that I will be keeping an eye on and I will keep you all updated.
