SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1025 AM CST Tue Jan 26 2021 Valid 261630Z - 271200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM THE FLORIDA PANHANDLE INTO COASTAL GEORGIA AND SOUTH CAROLINA... ...SUMMARY... A few strong to marginally severe thunderstorm gusts are possible today through tonight over parts of the Southeast, and a tornado cannot be ruled out. ...FL/AL/GA/SC... Deep southwesterly tropospheric flow is present today over much of the eastern CONUS, with the primary mid level jet extending from TX into the upper OH Valley. A surface boundary extends from southern SC southwestward into parts of southern GA, southeast AL, and the FL panhandle. A moist and marginally unstable air mass remains along and south of the boundary, with a few breaks in the clouds possible this afternoon. This will provide sufficient CAPE and forcing for scattered afternoon thunderstorms across the MRGL risk area. Flow fields are strong but veered. This would suggest that locally gusty/damaging winds are the main concern, although an isolated tornado is possible. Mid level heights will rise slightly this evening in between systems, before the next upper trough begins to approach AL/FL panhandle late tonight. Low level winds will strengthen before dawn in this area, with the potential for redevelopment of a few thunderstorms - with some risk of gusty/damaging wind or an isolated tornado. ..Hart.. 01/26/2021
