1. SVRL TORNADIC SUPERCELLS CONTINUE ENE FROM ECNTRL MS AND CNTRL AL
INTO ERN TN AT MID-EVENING. FAVORED ZONE OF ADDITIONAL SUPERCELL
DEVELOPMENT MAY OCCUR ALONG LOW-LEVEL CONFLUENCE ACROSS SWRN-CNTRL
AL THROUGH LATE EVENING. THIS WILL BE AMID THE MOST VOLATILE
COMBINATION OF EFFECTIVE SRH AND INSTABILITY AND THERE WILL BE A
DANGEROUS STRONG-VIOLENT TORNADO RISK SPREADING ENE THROUGH
CNTRL/NERN AL INTO NWRN AL AND SERN TN THROUGH THE EVENING HOURS.
AS A RESULT...THE HIGH RISK HAS BEEN EXPANDED EWD TO INCLUDE METRO

3. ALTHOUGH THERE WILL STILL BE A THREAT FOR ISOLD TORNADOES...DMGG
WINDS AND HAIL FROM THE OH RVR NWD TOWARD THE LOWER GREAT LAKES INTO
LATE EVENING...HIGHEST PROBABILITIES OF SUSTAINED SVR WEATHER WILL
REMAIN FROM KY COALFIELDS SWD. CONSIDERABLE CLOUDS AND RAIN HAVE
MITIGATED STRONG DESTABILIZATION TODAY PER 00Z ILN SOUNDING.

Alabama EM Director said that he fears many more deaths as large numbers of people are reported missing with search and rescue ongoing. Greg Forbes from TWC said tornadoes currently in eastern AL could approach the suburbs of Atlanta within about 2 hours.

Tornado passing south of Rome, Georgia is the same one that hit Tuscaloosa according to The Weather Channel. It has been on the ground for more than three hours now. If it started in eastern Mississippi like I thought I heard, that would make it another Tri-State Tornado...
