This trough aided in large-scale ascent ahead of a surface cold front that aided in supercell development across western and central Pennsylvania during the afternoon and evening with the tra...

Shear across western and central Pennsylvania remained relatively low, kee...

A line of convection formed ahead of an approaching frontal system on the afternoon of June 8th, 2015. Discrete rotating supercells formed ahead of the main line of storms, and one such cell produced an EF-0 tornado in Northumberland County.
Flash Flood — Jul 27, 2014
Training thunderstorms produced isolated flash flooding during the evening across the lower Susquehanna Valley.

Deep southerly flow transported a plume of seasonably high moisture into the region along a slow-moving, north-south oriented cold front. This favorable heavy rain pattern produced a stripe of 2.5-5.0 inches of rainfall from the northern Blue Ridge into the north-central mountains of Pennsylvania. Widespread small stream flooding and multiple road closures were reported with five river forecast...
