July 29th Daily Weather Discussion

High temperature July 28th @ KABE was 86 degrees. This was about two degrees above normal and fell in a positive departure range.

There is a cold front approaching the region. As of 03 Z this cold front was already approaching Western NY and NW PA. Showers and thunderstorms are out ahead of this front. The question becomes as to whether we see any severe weather today. Current thinking is that the front should be crossing the region between 12 Z and 18 Z. The timing of this front is in such that it would not be occurring during the time of the best day time heating. Also out ahead of this front currently … are showers and thunderstorms and a large area of cloudiness.

Position of the front as of 3 Z and cloudiness associated with it.

So it pretty much appears as if the bulk of the moisture is going to be moving thru between 12 z and 18 Z today. So because of this today pretty much looks like an isolated day for severe weather across SE PA, Southern NJ and points south. Showers and thunderstorms though can pretty much occur anywhere across the NE today along and ahead of the cold front but for the most part they will be non severe.

Highs today generally look to be in the 70s north to 80s to near 90 south.
