Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0751 PM CDT Thu Mar 14 2024 Valid 150100Z - 151200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM NORTHEAST TEXAS TO NORTHEAST ARKANSAS... ...SUMMARY... Large damaging hail, wind gusts, and a few tornadoes remain a threat from far northeast Texas to the Ohio Valley. ...01z Update... An elongated corridor of strong/severe convection continues this evening from northeast TX/AR into the OH Valley. Negligible height changes are expected along this corridor the rest of the period; although, several weak transient short-wave troughs will affect this region through 12z. One noteworthy short wave has encouraged a significant MCS over southeast MO/southern IL. An MCV may be evolving near STL which will track across southern IL into the OH Valley later tonight. Radar trends exhibit a narrow swath of scattered supercells extending downstream ahead of the larger MCS across central IN into central OH. This activity has longevity and will likely spread a bit farther east than earlier indicated. Given these trends, will extend severe probs across eastern OH into western PA to account for these supercells maintaining intensity into an otherwise weaker instability regime. Much stronger instability resides across central TX into central AR early this evening. Numerous supercells have evolved from the north central TX, across southeast OK into central AR. Most of these storms are producing large hail, some in excess of 2" in diameter. 00z sounding from LZK exhibits SBCAPE around 2500 J/kg with substantial deep-layer shear and adequate 0-3km SRH. In addition to large hail, tornadoes remain a risk with these organized supercells. ..Darrow.. 03/15/2024 Read more

MD 0242 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF SOUTHERN AND EASTERN OHIO INTO NORTHWESTERN WEST VIRGINIA
Mesoscale Discussion 0242 NWS Storm Prediction Center Norman OK 0625 PM CDT Thu Mar 14 2024 Areas affected...Portions of southern and eastern Ohio into northwestern West Virginia Concerning...Severe potential...Watch unlikely Valid 142325Z - 150100Z Probability of Watch Issuance...20 percent SUMMARY...Discrete storms have tried to initiate in southwestern Ohio into northern Kentucky. Additional organized storms will eventually reach the upper Ohio Valley later this evening. The need for a watch is quite uncertain in the short term, but convective trends will be monitored. DISCUSSION...Storms have attempted to initiate in southwestern Ohio into northern Kentucky. While it is not clear whether this activity will mature, regional VAD profiles suggest that these storms would be capable of large hail and tornadoes. Later in the evening, storms currently in southern Illinois into central Indiana will likely reach the upper Ohio Valley. An airmass supportive of severe storms continues to try and work eastward. There is at least some possibility that an organized line will reach these areas and require a downstream watch. However, uncertainty remains too high to issue one at this time. Convective trends will continue to be monitored. ..Wendt/Hart.. 03/14/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...PBZ...RLX...CLE...ILN...
