Read the full account →An upper level impulse moving along a wavy frontal boundary produced scattered thunderstorms with very heavy rainfall the morning of the 3rd. Some roads were closed due to flash flooding in Beaver county, while radar estimated nearly 4 inches of rain fell in 2 hours northeast of…

A tremendous amount of runoff and snowmelt, combined with the fact that the Monongahela and the Allegheny Rivers crested in phase, resulted in the maximum possible crest possible at the…

Read the full account →A stationary front poised in the vicinity of central New York and northeast Pennsylvania was the focus for very warm and moist atmospheric conditions across the region.
Read the full account →A warm front helped to focus the remnants of tropical cyclone Beryl which brought steady rainfall and embedded thunderstorms to the region. A cold front then brought a second round of thunderstorms in the evening.
Read the full account →Slow-moving low pressure over Northeast Pennsylvania was the focus for a constant stream of heavy rain-producing thunderstorms during the overnight hours. A quick rainfall of 2.5 to 3.5 inches caused swollen streams and areas of flooding.

Read the full account →The stalled boundary began to lift north during the day on the 17th but remained the focus of diurnal convection. While the front did eventually shift off to the east on the 18th, additional storms were able to fire with the lingering moist airmass as an upper level disturbance…
