The National Weather Service has issued a flash flood watch throughout southwestern Pennsylvania from 6 p.m. through 11 a.m. Thursday.
Rain will develop this evening and continue overnight, but is not expected to mimic the severe weather that crossed the region last night, Lee Hendricks of the National Weather Service in Pittsburgh said.
Parts of northern West Virginia, including the panhandle, and eastern Ohio as far west as Zanesville, also are under the flood watch.
Temperatures will reach the lower 80s today, then fall to the upper 60s tonight and stay humid.
Widespread thunderstorms packing heavy rain moved across southwestern Pennsylvania and nearby areas overnight, and caused water ponding and runoffs on roads and, in some locations, flooding.
Some locations received more than 2 inches of rain in six hours, including Cheswick and Donegal in Westmoreland County, Mr. Hendricks said.
Duquesne Light said, as of noon, 2,950 customers were still without power, but that they expected all to be restored by 2 p.m. The Sewickley Public Library also was closed this morning because of a power outage.
PennDOT had said it planned to close the right southbound lane of Route 28 this afternoon for repairs resulting from the storms, but later decided not to do the work.
The weather service flood warning expired at 6:45 a.m. today for parts of eastern Ohio, the northern West Virginia panhandle and into Western Pennsylvania, encompassing southern Beaver, northern Washington and most of Allegheny counties. No further watches or warnings have been posted.
Street flooding was reported to the weather service along Saw Mill Run Boulevard, Freeport Road at Powers Run Road and Allegheny Boulevard in Allegheny County.
Additionally, there were cases of road closures because of fallen trees, downed wires and dysfunctional traffic lights this morning.
Around 3 a.m., radar estimated showed 1 to 3 inches of rain had fallen with more precipitation continuing.
