2,274 first-hand accounts of flood events in Pennsylvania, ranked by impact. Each is a NOAA-written narrative of the moment.
Low pressure tracked northeastward across Michigan and eastern Canada, pushing a warm front across western Pennsylvania in the morning, with some showers and thunderstorms ahead of it.
Read the full account →Showers and thunderstorms formed along a nearly stationary boundary that crept southeastward from the Great Lakes. Precipitable water values of around 1.6 inches and weak steering flow along the boundary led to a few areas of training thunderstorms.

Read the full account →Heavy rain with little, if any, lightning moved along a stationary front in a tropical environment. Moisture was plentiful, with precipitable water values of over 2 inches.
Read the full account →A wavy and nearly stationary frontal boundary was in place near the Mason-Dixon Line. Morning clouds hindered destabilization somewhat, but afternoon clearing and the arrival of a mesoscale low allowed storms to blossom during the afternoon and evening.
Read the full account →Warm and humid conditions were in place across western Pennsylvania on June 13th behind a warm front. After morning showers departed, instability was able to build during the afternoon hours.
