The National Weather Service forecast offices in Norton and Albany have issued the attached forecast packages concerning the potential for strong to severe thunderstorms Tuesday afternoon and evening, especially across central and western Massachusetts. The risk for damaging storms is from 12 p.m. to 7 p.m. in western Massachusetts, and from 2 to 9 p.m. in central Massachusetts. The primary concerns are for damaging straight line winds, hail, dangerous lightning, and isolated tornadoes.

From the National Weather Service in Norton (for all of Massachusetts except Berkshire County): The threat for strong to severe storms remains across interior southern New England this afternoon and evening.

What — Scattered severe thunderstorms with the main threat being damaging straight line wind gusts.

When — Between 2 and 9 p.m. this afternoon and evening. There could be a few isolated thunderstorms between 2-4 p.m., but appears the main line of severe weather will move into the region around 4-5 p.m.

Where — Highest risk for severe thunderstorms is across western/central Massachusetts and northern Connecticut, but can not be ruled out across the rest of the region including the near shore waters.

Uncertainty:
• It is possible that we see a decent area of straight line wind damage in portions of western/central Massachusetts and into northern Connecticut.
• It is also possible that the bulk of the severe thunderstorms may shift a bit to our southwest, but northern Connecticut still looks like it could be impacted.
• Cannot rule out the potential for an isolated tornado across the interior.

From the National Weather Service in Albany (for Berkshire County):

• There is a slight to enhanced risk for severe thunderstorms this afternoon into the early evening hours mainly along & south of Interstate 90.
• Main threat is for damaging wind gusts with large hail also possible, mainly along and south of I-90.
• There also is a marginal risk for an isolated tornado, again mainly along & south of I-90.
