For The Rest Of Today: Lots of sunshine is expected throughout the rest of today. High temperatures this afternoon will be between 43 and 46 Degrees.
Tonight: Gradually increasing high clouds and light winds this evening will allow temperatures to drop quickly into the upper 20s to low 30s. These temperatures will rise a little after midnight tonight as clouds lower and thicken ahead of an area of low pressure moving northeastward from the Mid-Atlantic states.
Rain will overspread Western Mass between 1 am and 3 am and then overspread Central Mass between 2 am and 4 am. Temperatures across a large part of Western and Central Mass should be just above freezing after midnight tonight, so this should be a cold rain for most.
The exception to this may be the higher terrain of the Worcester Hills and the Berkshires where some freezing rain may occur briefly late tonight.
Sunday: A soaking cold rain is expected throughout the day on Sunday as a strengthening low pressure system tracks to near Nantucket.
Any leftover freezing rain over the higher terrain of the Worcester Hills and Berkshires will change to rain by mid to late morning Sunday with all rain Sunday across the rest of Western and Central Mass.
Given that this storm system will be strengthening at a pretty decent rate, it looks likely that the rain will fall heavily at times during the day on Sunday. Rainfall totals of one inch (1.00”) to one and one half inches (1.50”) are expected on Sunday.
I am keeping a very close eye on the possibility of the rain changing to a period of wet snow Sunday afternoon across the Berkshires and the Worcester Hills as that low pressure system moves away and draws in some slightly colder air. One reason this may not happen is that there is no cold high pressure system over southeastern Canada or northern New England. So, we are going to be depending on how hard the rain falls & cools the atmosphere.
At this point, this flip from rain to wet snow could happen first over the Berkshires during the early and mid-afternoon hours of Sunday and then across the Worcester Hills by late Sunday afternoon. Any snow accumulation Sunday afternoon will be light and should be in the range of a dusting to around one inch. The highest terrain along the east slopes of the Berkshires could see up to 2 inches of snow accumulation Sunday afternoon.
All-in-all, this looks to be a cold rain for Sunday for most and any snow accumulation Sunday afternoon will be minor and confined to the higher terrain of Western and Central Mass.
Sunday Night: That low pressure system will continue to move away on Sunday night. Rain and higher elevation wet snow will end between 7 and 9 pm with clearing expected after midnight. In addition, winds are expected to shift into a northwesterly direction and become quite gusty with wind gusts of 25 to 35 mph expected during Sunday night.
Low temperatures Sunday night will be near 30 Degrees.
Monday Through Tuesday: Sunny skies are expected on both Monday and Tuesday. High temperatures Monday will be near 45 Degrees. High temperatures Tuesday will be between 50 and 55 Degrees.
Wednesday: A cold front will move across the region on Wednesday bringing with it cloudy skies and some scattered rain shower activity. High temperatures Wednesday will be between 50 and 55 Degrees.
The bigger concern with this frontal passage will be the potential for strong gusty winds, especially on Wednesday night and Thanksgiving Day. Southwest winds are expected to gust up to 30 to 35 mph during Wednesday. These winds will shift into a northwesterly direction on Wednesday night and could be quite gusty with wind gusts of up to 40 to 50 mph possible.
Thanksgiving Day: Sunny skies and quite windy conditions are expected on Thanksgiving Day. High temperatures will be between 35 and 40 Degrees. West to northwest winds may gust up to 40 to 50 mph at times.
Friday Through Next Saturday: Plenty of sunshine is expected on both Friday and next Saturday. High temperatures both days will be between 35 and 40 Degrees.
