Showers and winds bringing cool air from the northwest helped keep temperatures in the 60s and 70s Wednesday, according to the National Weather Service.
Hagerstown weather watcher Greg Keefer recorded .17 inches of rain by 8:30 p.m. and a high of 73 degrees, in sharp contrast to a recent heat wave.
Nine out of 10 days through Monday had been 90 degrees or above.
The National Weather Service issued a flash flood watch for the Hagerstown area Wednesday night because of a tropical air mass expected to move into the area overnight, meteorologist Andy Stern said.
The watch expires at 11 a.m.
Stern said rain should continue into the morning with a possible thunderstorm before tapering off in the afternoon. The rain will help keep the high temperature for Thursday in the mid-70s.
