Snow Tuesday Evening Which Will Be Closely Followed By Heavy Rain & Strong Southerly Winds Late Tuesday Night & Early Wednesday Morning Is Expected Across Western & Central Mass

For Tonight: An area of high pressure will move right over the area during tonight leading to clear skies. Low temperatures will be between 15 and 20 Degrees. Winds will be West at 5 to 10 mph.

Tuesday: That high pressure system will be in place over the area during the morning before it moves to the east and a strong low pressure system begins to approach the region from the west.

Skies will start out partly sunny, but will quickly become cloudy by mid to late morning. Cloudy skies are then expected during the afternoon. In addition to this, precipitation in the form of snow looks to overspread the entire region around sunset Tuesday.

High temperatures will be between 35 and 40 Degrees. Winds will be Southeast at 10 to 20 mph.

Snow Tuesday Evening Which Will Be Closely Followed By Heavy Rain & Strong Southerly Winds Late Tuesday Night & Early Wednesday Morning: A strong low pressure system is expected to push across western and northern New England late Tuesday night into Wednesday morning bringing with it multiple hazards, including accumulating snow to start that changes to heavy rain, river and stream flooding & strong southerly winds.

It is likely to snow for a few hours during Tuesday evening, especially across the northern Worcester Hills and the Berkshires. This snow will flip to heavy rain by midnight Tuesday night. Snowfall amounts during Tuesday evening before the snow changes to rain will be a dusting to perhaps an inch across most areas. The exception to this looks to be across the northern Worcester Hills and the Berkshires where 1 to 2 inches of snow accumulation seems likely.

Heavy rain and perhaps even a thunderstorm or two is then expected throughout the after midnight hours of Tuesday night. Rain, which will be heavy at times, is then expected to continue through sunrise Wednesday morning before it comes to an end by mid-morning Wednesday.

Total rainfall amounts of between 2 and 3 inches can be expected in about a 6 hour time span. This is extremely concerning given the 8 to 16 inch snow pack that we’ve got out there as the heavy rain combined with quickly melting snow will lead to a substantial flood threat late Tuesday night into Wednesday. Flooding of rivers, creeks, streams and other low-lying and flood prone locations is very likely. In addition, flooding is also expected in poor drainage and urban areas.

In addition to the heavy rain, we are going to have to keep an eye on the potential for strong south winds during the after midnight hours of Tuesday night. At this point, it looks like south to southeast winds will be 15 to 25 mph with gusts to 30-35 mph during Tuesday evening and then south to southeast winds will be 20 to 30 mph with gusts to 40 to 50 mph after midnight Tuesday night.

These strong winds may lead to some downed tree limbs and even downed trees leading to isolated to scattered power outages during the after midnight hours of Tuesday night.

One thing that needs to be watched is if there is any thunderstorms, it could pull down some of the really strong winds (60-70 mph wind gusts) that will be present at about 1000 to 2000 feet above the ground. Something to watch out for, just in case.

Temperatures during Tuesday night will rise to 40 to 45 Degrees after midnight with temperatures on Wednesday morning reaching 44 to 49 Degrees.

And Yet Another Rain Storm Is Expected Friday Night: This very active weather pattern is expected to continue right through the end of this week and this coming weekend. Yet another strong storm system will move across western and northern New England leading to another round of heavy rain and strong southerly winds during Friday night.

Rainfall amounts of a possible 1 to 2 more inches could exacerbate the flood issues across the region and it’s something that will need to be watched extremely closely.
