SPC Apr 14, 2022 0100 UTC Day 1 Convective Outlook

SPC 0100Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0800 PM CDT Wed Apr 13 2022 Valid 140100Z - 141200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM PARTS OF THE OH VALLEY INTO THE LOWER MS VALLEY... ...SUMMARY... Thunderstorms capable of damaging winds and a few tornadoes will continue into late tonight from parts of the Ohio and Tennessee Valleys into the lower Mississippi Valley. ...OH/TN Valleys into the lower MS Valley... An extensive QLCS, with multiple embedded bowing segments, will continue moving eastward into late tonight. The northern portion of the QLCS (roughly from northern AL into the OH Valley) will be moving into a less unstable environment with time, though the well-defined rear-inflow jets noted on recent NQA and PAH VWPs may allow the bowing segments to persist into late tonight before instability wanes completely. Damaging wind gusts will be the primary hazard with these bowing segments, though a brief tornado or two remain possible with stronger embedded circulations. Further south, from LA into MS and southwest AL, where there is a more substantial reservoir of low-level moisture and instability, some severe threat will likely persist into the overnight hours. The primarily linear mode will result in a continued threat of strong/damaging wind gusts and brief tornadoes associated with embedded circulations. Discrete cells have thus far struggled to intensify before becoming absorbed into the line, but low-level shear will remain sufficient to support a conditional tornado threat with any longer-lived supercell that can develop ahead of the main QLCS. ..Dean.. 04/14/2022 Read more CHECK UPDATE ZOOM GRAPHIC
