This storm is a perfect example of how differently KOKX and the Philadelphia NWSFO's see severe thunderstorm warnings. Philadelphia still has a severe thunderstorm warning out for the cell even though the cell is north of the warning polygon.

Yeah the disparity has been pretty interesting this season especially. Oddly Upton still has flash flood watches out which seems a little overdone. If storms pop up I could see FF warnings but not sure a watch is needed except in spots that have had excessive rainfall yesterday. It's also odd that some of the strongest storms all season have occurred this week without any watches out. Is there a certain overall area coverage that needs to be met in order for a watch to be issued?

The way these storms are training I doubt we see much sun today when they pass to fire some more storms this afternoon/evening...any thoughts on how this may affect the storm potential for later today?

Yell at me if im wrong, but im pretty sure that the storms now, we kill any chances of them later, unless we clear out in a hurry.

once the line thats currently in western Jersey passes through we could see some breaks in the clouds but this won't be a day with high SBCAPE. Its mostly elevated CAPE thats getting it done.
