Mesoscale Discussion 0985 NWS Storm Prediction Center Norman OK 0400 PM CDT Sun May 26 2024 Areas affected...portions of eastern Ohio into extreme western Pennsylvania...central West Virginia...extreme western Virginia...extreme western North Carolina...extreme eastern Tennessee Concerning...Severe Thunderstorm Watch 316...317...318... Valid 262100Z - 262230Z The severe weather threat for Severe Thunderstorm Watch 316, 317, 318 continues. SUMMARY...The severe threat continues across Severe Thunderstorm Watches 316-318. Strong wind gusts are the main threat with a persistent QLCS. Large hail is also possible across far eastern TN and western NC, where supercells are ongoing. DISCUSSION...A long-lived QLCS with a history of wind damage continues to move eastward across the central Appalachians, where surface temperatures are above the 80 F mark. As such, enough buoyancy exists to support strong wind gust potential with the QLCS for at least a few more hours. Along the TN/VA border area, supercell development has recently occurred, where MLCAPE has also climbed to over 2000 J/kg, coincident with 50+ kts of effective bulk shear. Here, large hail is also a concern in addition to strong wind gusts. ..Squitieri.. 05/26/2024 ...Please see www.spc.noaa.gov for graphic product...
