Areas affected...Mid-Atlantic States

Concerning...Severe potential...Watch unlikely 

Valid 281932Z - 282130Z

Probability of Watch Issuance...20 percent

SUMMARY...To the south of WW 505, an additional WW is not
anticipated although locally damaging winds will be possible into
early evening.

DISCUSSION...Isolated showers have recently deepened into a few
thunderstorms from central to southeast PA, south of WW 505. The
environment within/ahead of this activity is broadly characterized
by MLCAPE around 1000 J/kg. With poor mid-level lapse rates and
weaker large-scale ascent relative to NY and western New England,
confidence is low in a more organized severe threat developing
across the DE Valley and Piedmont vicinity. Nevertheless, with
surface temperatures having warmed into the upper 80s and low 90s,
potential will exist for microbursts capable of localized tree
damage with the strongest cells as they spread towards the coastal
plain.
