Mesoscale Discussion 1566 NWS Storm Prediction Center Norman OK 0542 PM CDT Tue Jul 09 2024 Areas affected...northern Kentucky...southern Indiana...far southwestern Ohio Concerning...Tornado Watch 516... Valid 092242Z - 100015Z The severe weather threat for Tornado Watch 516 continues. SUMMARY...Tornado threat continues within WW516. DISCUSSION...Supercells have been ongoing along and near the warm front extending across northern Kentucky into southern Indiana. One ongoing supercell north of Evansville, IN near Johnson, IN has produced multiple tornadoes across northern Kentucky into southern Indiana. A more narrow favorable corridor of tornado threat should be maintained in the next few hours across the Indiana/Kentucky border along the Ohio River. Within this region, the 850 mb jet will increase and subsequently contribute to the most favorable region of effective SRH around 200-300 m2/s2. Any semi-discrete cells that can track northward/northwestward into this region will likely take advantage of more favorable low-level SRH, taking on supercell characteristics and potential for tornadoes as they track near the warm front. This corridor will shift northeastward through the evening across southern Indiana and eventually southwestern Ohio through time. ..Thornton/Gleason.. 07/09/2024 ...Please see www.spc.noaa.gov for graphic product...
