Scattered severe thunderstorms should continue this evening across parts of the Ohio Valley into the Mid-Atlantic. Large to very large hail should be the main threat, although an isolated strong wind gust remains possible. ... 01Z Update ... Showers and thunderstorms continue across the Ohio Valley into the northern Mid-Atlantic. These storms are being aided by increasing large-scale ascent associated with a gradually amplifying midlevel trough and vertical circulations associated with a south-southeastward moving cold front. The anafrontal nature of the cold front is supporting thunderstorm development/intensification on the cold side of the boundary, where surface temperatures quickly fall into the 40Fs. Most unstable CAPE between 500-1500 J/kg, steep midlevel lapse rates ranging from 6 C/km across Pennsylvania to 8.5 C/km across southern Indiana, and strong cloud-layer shear will support a continued hail threat into the evening hours. The overall wind potential has diminished across most of the area as low-levels stabilize. However, given increasing storm coverage an isolated strong-to-severe wind report may still be possible. The most likely area for this is across far southeast Illinois into southwest Indiana where better midlevel lapse rates and greatest storm coverage coincide.
