Large hail and strong gusts would accompany any stronger storms that develop. DISCUSSION...An increase in cumulus has been noted in visible satellite imagery over the past hour, especially from eastern KY into West Virginia. Strong heating and surface dewpoints in the mid 50s to mid 60s F beneath very steep midlevel lapse rates are resulting in MLCAPE up to 1500 J/kg. While large-scale ascent is weak over the region, continued heating and erosion of weak inhibition amid 30-40 kt of midlevel northwesterly flow, should foster at least isolated thunderstorm development over the next few hours. Any storms that develop would have potential to become severe, with steep midlevel lapse rates and straight/elongated hodographs supporting severe hail. Additionally, steep low-level lapse rates also will foster some potential for strong/locally damaging gusts. Some uncertainty exists in timing and westward extent of severe potential. The MCD area will continued to be monitored for possible watch issuance over the next few hours. ..Leitman/Smith.. 04/15/2024 ...Please see www.spc.noaa.gov for graphic product...
