Showers and Thunderstorms from the Great Lakes into the Southern Plains

Frontal boundary and wave of low pressure will keep an active weather pattern from the Great Lakes region through the southern Plains the next couple of days. Isolated instances of severe thunderstorms and flash flooding are possible. Meanwhile, as summer comes to a close, above normal temperatures continue for central and eastern U.S. - especially for most of Puerto Rico with excessive heat. Read More >

Overview

For the second straight day, York County, PA, bore the brunt of the Thunderstorms that formed over Central PA. The afternoon and evening brought many thunderstorms to the state, but the repeated thunderstorms over York County produced a widespread flooding event that affected most of the southern two- thirds of the county. The rains were less concentrated than the day before, but the already-wet ground and torrential downpours produced many more flooding reports than Thursday (the 1st). Traffic on the southbound side of Interstate 83 to the south of the City of York (near the Glen Rock Exit) was slowed or stopped due to a foot or more of water on the roadway surface. In addition to the flooding, a rotating thunderstorm cell produced at least two incidents of wind damage south of the City of York.
