Overview

A few Supercell thunderstorms developed well to the north of a warm front draped over Southwestern PA, and dropped into Central Pennsylvania from the north during the evening of the 25th. The storms formed in a high shear environment (as indicated by the 00z 26th sounding from KBUF - right at the genesis of these cells).

Many of these storms exhibited very strong and deep rotation, and were very long-lived. See the image loop below and follow the track of a monster storm that began near Buffalo, NY and did not dissipate until it hit the Atlantic coast of NJ !! That storm produced severe weather all along it's path despite being well back in the cooler, more stable air.
