Heavy rainfall led to major flooding destruction across the East on June 27 and 28.
AccuWeather Expert Forensic Meteorologist Steve Wistar, who has been tracking rainfall amounts in Lemont, Pa., for the past 23 years, recorded 3.53 inches of rain Thursday evening, the most he has ever seen from a non-tropical system in that area.
Some of the heaviest rain on Thursday was focused along the I-80 corridor across Pennsylvania, dropping over 4 inches in just a few short hours in some locations.
Roads were closed across the mid-Atlantic, and a washed-out bridge in Sykesville, Pa., was reported by an emergency manager.
On Thursday afternoon, a tornado spawned from a series of thunderstorms in Boalsburg, Pa., near State College. The NWS classified this tornado as an EF-1, as it touched down on an area farm.
The incidents of flooding did not stop with the conclusion of Thursday with additional reports from North Carolina to the Northeast on Friday.
Flood waters washed out a bridge at Huntersville, N.C., while major flooding unfolded in Stockbridge, N.Y., after a levee was breached.
