A watch will likely be issued for parts of the area within an hour or two. DISCUSSION...Latest surface analysis shows a surface low over northern WV, with a quasi-warm front extending eastward across MD into southern NJ. Along/south of the front, diurnal heating within cloud breaks and lower/middle 60s dewpoints are contributing to around 1500 J/kg MLCAPE. As storms spread/develop eastward into the destabilizing air mass, 40-50 kt of effective shear should favor gradual intensification/organization into semi-discrete clusters and supercells. Enhanced clockwise hodograph curvature (around 150 m2/s2 effective SRH) ahead of the east-northeastward-moving surface low will support the potential for a few tornadoes (along with locally damaging wind gusts) with the more organized supercells that evolve. A watch is likely for parts of the area within an hour or two. ...Weinman/Smith.. 05/30/2025 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!_Tcxy19mj6Q9FKgtR9SYznrgM7nrvqzCjEV323cf4wdy8DVl54fIEC0SmEDDKu8f88j2Wn_0P= OfQ1RUZAdArZiNSRuY$ for graphic product...
