BOSTON (WBZ-AM) -- The National Weather Service said strong winds and heavy rain were due to hit the Boston area Thursday.
A flash flood watch was posted for eastern Massachusetts and Rhode Island through this afternoon.
WBZ-TV meteorologist Pamela Gardner said there were potential rainfall rates of 1"-2" per hour from any storm moving through.
"Some of those storms could be strong, with damaging wind gusts and also dangerous cloud-to-ground lightning," she said. "Maybe an isolated severe thunderstorm with gusty wind that could become damaging."
The storms provide a break in the heat wave. Cooler temperatures and lower humidity are on the way, with an overnight low of 59 degrees expected in Boston.
"Overnight tonight you'll notice a big change, with the wind coming from the north, dryer air lowering humidity, temperatures overnight in the 50s," Gardner said.
