Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0649 PM CST Sun Dec 29 2019 Valid 300100Z - 301200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM FAR SOUTHERN MIDDLE TENNESSEE SOUTH-SOUTHWESTWARD TO EXTREME EAST-CENTRAL MISSISSIPPI... ...SUMMARY... A few severe thunderstorms will persist this evening across parts of the mid South, Tennessee Valley, southern Appalachians, and central Gulf Coast states. Locally damaging gusts and a tornado or two are remain possible. ...Discussion... A gradual decrease in storm intensity -- and thus severe risk -- continues at this time across the Tennessee Valley area south along the Mississippi/Alabama border vicinity. A continuous line of convection -- with embedded thunderstorms -- extends from southern Middle Tennessee to eastern Louisiana, and continues moving quickly eastward. The strongest storms are moving across the Slight Risk area -- mainly across west-central and northwestern Alabama, where around 500 J/kg mixed-layer CAPE is indicated, within a very favorable kinematic environment. As weak nocturnal cooling continues across the pre-frontal warm sector, a continued, gradual decrease in convective intensity will continue overall. Still, given the strength of flow aloft, some severe risk may linger into the overnight hours, as storms shift eastward toward, and eventually across, the southern Appalachians region through the end of the period. ..Goss.. 12/30/2019Read more
