Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1245 AM CDT Sat Apr 22 2017 Valid 231200Z - 241200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF GEORGIA AND THE CAROLINAS... ...SUMMARY... Marginally severe thunderstorms with strong wind gusts and hail will be possible on Sunday across parts of Georgia and the Carolinas. ...Georgia/Carolinas... An upper-level low is forecast to move eastward across the Tennessee Valley on Sunday. At the surface, a low is forecast to track across Georgia as a cold front advances eastward from Alabama into western Georgia by afternoon. Thunderstorm development is expected to take place along the front during the day with convection moving from west to east across the region during the mid to late afternoon. Other thunderstorms may develop along a quasi-stationary front extending eastward across South Carolina. NAM forecast soundings just ahead of the cold front and surface low in central and eastern Georgia at 21Z on Sunday show SBCAPE in the 500 to 1000 J/kg range with 0-6 km shear of 40 to 45 kt. This may be enough for a marginal wind damage threat as low-level lapse rates steepen in the afternoon. Any severe threat should remain isolated and in a narrow window around peak heating. ..Broyles.. 04/22/2017Read more
