kayman Posted January 12, 2023 Author Share Posted January 12, 2023 Mesoscale Discussion concerning Metro Atlanta Quote Mesoscale Discussion 52 < Previous MD Mesoscale Discussion 0052 NWS Storm Prediction Center Norman OK 1052 AM CST Thu Jan 12 2023 Areas affected...east central Alabama and western Georgia Concerning...Severe potential...Tornado Watch likely Valid 121652Z - 121745Z Probability of Watch Issuance...80 percent SUMMARY...Tornado threat continues along the eastern advancing line of storms which is expected to move into east central Alabama/Georgia later today. DISCUSSION...A line of thunderstorms continues to advance eastward through northern Alabama. Within this line, transient circulations have been noted on radar. Ahead of this line, the KMXX (Maxwell Air Force Base) VAD profile depicts 0-1 km storm relative helicity around 150-200 m2/s2. 15z RAOB from BMX indicates upstream 0-1km SRH around 300 m2/s2. The wind field over eastern Alabama/Georgia is expected to increase through the afternoon as flow aloft increases in the next few hours. RAP analysis shows 850 mb winds increasing to around 45-50 kts by 19-20z. Surface objective analysis indicates surface based CAPE around 1000-1500 j/kg across this region and the convective inhibition is reduced. This environment will continue to be conducive to tornado development within the line of storms, with the threat gradually spreading east through the afternoon. A Tornado Watch downstream of WW17 will likely be needed for portions of eastern Alabama and western Georgia this afternoon. ..Thornton/Guyer.. 01/12/2023 ...Please see www.spc.noaa.gov for graphic product...
