BOSTON -- A tornado watch has been issued for Monday afternoon for western parts of Massachusetts.
A tornado watch is in effect for Berkshire County until 6 p.m. Monday.Severe weather will move across western Massachusetts, Connecticut and possibly southern New Hampshire late Monday afternoon and evening.
A line of severe thunderstorms were moving through New York state and Pennsylvania early Monday afternoon. This activity is expected to continue to move eastward reaching western Massachusetts and Connecticut after 4 p.m. Monday. The main threat with these storms will be strong damaging straight line wind gusts to 60 mph. However, a weak brief tornado cannot be ruled out across extreme western Massachusetts and western Connecticut.A marine layer is in place across southern New Hampshire and central Massachusetts. Therefore, as the line of severe thunderstorms progresses east, they will begin to weaken. However, a severe thunderstorm or two is possible in this region as well.By the time the activity reaches eastern Massachusetts and Rhode Island later Monday evening, the loss of daytime heating and the strong marine influence should have weakened the storms below severe limits. However, dangerous cloud to ground lightning will still be possible.
