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
