Another day with intriguing severe wx potential in Eastern PA/NJ on Thursday. Sfc boundary and impressive instability axis. Some enhanced low level shear near/along this boundary - perhaps a wind/isolated tornado threat. Bad mid level lapse rates a mitigating factor. #njwx #pawx pic.twitter.com/tV3poC5GYR
