DISCUSSION...A couple of strong storms have developed across southeast PA early this afternoon, within a warm, moist, and generally uncapped environment. The 12Z IAD/WAL soundings and recent forecast soundings depict a warm layer around 600 mb that will limit instability to some extent, but continued strong heating should allow for MLCAPE to increase into the 1500-2500 J/kg this afternoon. Low/midlevel flow is generally weak, but somewhat stronger upper-level flow could allow for some occasional modest storm organization, and the strongest storms will be capable of producing isolated damaging wind and small to near-severe hail. Storm coverage is somewhat more uncertain with southward extent, but at least isolated development is expected into parts of MD and eastern VA, where temperatures rising well into the 90s F and steepening low-level lapse rates will support an isolated damaging-wind threat with any robust updrafts later this afternoon. ..Dean/Hart.. 07/14/2024 ...Please see www.spc.noaa.gov for graphic product...
