For The Rest Of Today: A strong area of high pressure will bring lots of sunshine to Western and Central Mass throughout the rest of today. It will be unseasonably cold for this time of year, however, with high temperatures of between 34 and 38 Degrees. North winds will continue to gust up to 25 to 35 mph through midday and then gradually decrease this afternoon.
Tonight: Record cold temperatures are expected tonight due to a strong area of high pressure that will be located over our area.
Clear skies with a 5 to 10 mph north wind will lead to low temperatures of 10 to 15 Degrees across Western Mass and 15 to 20 Degrees across Central Mass. The record low temperature tonight in Springfield is 16 Degrees. The record low temperature tonight in Worcester is 15 Degrees. I do think Springfield’s record low temperature will be broken, however Worcester may just miss seeing a record low temp tonight.
Sunday: An area of low pressure will be strengthening as it moves northward from the North Carolina coast during Sunday.
There is expected to be plenty of dry air around, so no precipitation is expected on Sunday. There will be, however, an increase in cloudiness from east to west during Sunday afternoon.
High temperatures Sunday will be between 35 and 40 Degrees.
Sunday Night Through Monday Night: The weather forecast for Sunday night and Monday continues to be uncertain as an area of low pressure will be tracking off of the Mid-Atlantic and New England coastline. Some of weather forecast guidance points to a well offshore storm track while other forecast guidance is forecasting a storm track that takes this low pressure system right across Nantucket on Monday afternoon.
This difference in the data has large implications on the weather forecast for Sunday night and Monday. A further offshore storm track would lead to some periods of light rain and freezing rain very late Sunday night and Monday. On the other hand, a much closer storm track would lead to a much more steady rain on Sunday night that lasts through Monday.
At this point, I’m leaning much more towards the more offshore storm track as I don’t think there is enough amplification in the upper level trough of low pressure to cause the low pressure system to track further west.
So, on Sunday night, I think that we will see cloudy skies with precipitation moving in from southeast to northwest. Temperatures later Sunday night will be near or just below freezing across Western and Central Mass, especially in the higher elevations across the Hilltowns of Western Mass and across the Worcester Hills. This means that some light freezing rain is possible across the Hilltowns of Western Mass and across the Worcester Hills late Sunday night.
Across the Pioneer Valley, the Merrimack Valley and the Blackstone Valley, temperatures may not cool enough for freezing rain to occur and instead light rain looks possible late Sunday night. With that said, should we see temperatures cool a little more than forecast, then some icing could occur in the valleys as well.
In any event, this looks to be a minor icing event that will impact Monday morning’s commute.
Any light freezing rain will change to all rain by later Monday morning with periods of light rain expected to continue through Monday afternoon and Monday evening.
Towards the end of this storm, some colder air may wrap around late Monday night causing light rain to change to a brief period of light snow before ending around sunrise Tuesday morning.
Tuesday: A cloudy day is expected on Tuesday with high temperatures near 45 Degrees.
Wednesday Through Thursday: Partly sunny skies are expected on both Wednesday and Thursday. High temperatures Wednesday will be near 45 Degrees. High temperatures Thursday will be near 50 Degrees.
Friday: A frontal boundary is expected to cross the region on Friday bringing with it scattered rain showers. High temperatures Friday will be between 50 and 55 Degrees.
