WBZ-TV meteorologist Pamela Gardner said there were potential rainfall rates of 1"-2" per hour from any storm moving through.

Once today's cold front passes through southern New England, a much cooler and less humid airmass moves into the region. Check out the overnight lows for tonight. 👍 pic.twitter.com/IswtY2f66s— NWS Boston (@NWSBoston) July 6, 2018
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.
