Not So Thundery Tonight


Our evening snapshot of weather is rather tranquil locally outside of a severe thunderstorm a couple of hours ago in South and Central Jersey.  We've been "blessed" with unfavorable low level winds and a modestly dry lower atmosphere thanks to those westerly winds drying us out at the surface.   This is despite favorable upper level dynamics and the trigger in the form of a weak cold front.      You can see that boundary slipping south on radar across Pennsylvania -- generally along I-80 across the state at this hour.   Unfortunately for storm chasers, the best support for thunderstorms is farther west and by the time those storms work towards our region, well after sunset, they may very well weaken enough to be a non factor locally.   The storms farther south, across West Virginia and south of Pittsburgh, might clip parts of the Delmarva later on this evening as they work east-southeast.

We alluded to the downer in today's severe weather potential being the westerly winds and that ended up being the bane in today's severe weather prospects...not that anyone is complaining.

Temperatures today were quite warm around Philadelphia, topping out at 86 degrees in what is our warmest temperature so far this month.  Today's high actually missed a record by just four degrees (record last set in 2004 and originally set in 1964).   This evening...and the next several days...will be quite warm as a ridge of high pressure builds aloft and we make a run at 90 later on this week.
