An interesting environment across far eastern Pennsylvania for a bit in vicinity of a warm front. Backed low-level winds, mesoanalysis is showing pockets of 200 m2s-2 ESRH and there is modest instability. Could support a few brief tornadoes and this may cross into far western New Jersey.

So whats the verdict on the Lehigh County funnel?  Any pictures or current reports from the area?  My parents live in Fullerton

N&W burbs are in the sweet spot for severe. A few cells to the west look like they could produce.
