AREAS AFFECTED...NERN MS AND NRN AL

CONCERNING...TORNADO WATCH 789...

VALID 222315Z - 230015Z

TORNADO WATCH 789 EXPIRES AT 00Z...BUT MAY BE LOCALLY EXTENDED FOR A
LINGERING TORNADO THREAT FOR A COUPLE OF HOURS BY THE LOCAL WEATHER
FORECAST OFFICES.

CLUSTER OF STRONG-SEVERE TSTMS HAS BEEN WEAKENING ACROSS NRN AL
SINCE 2230Z WITH OTHER ISOLD SUPERCELLS MOVING NWD ALONG THE TN/AL
BORDER.  THESE STORMS APPEAR TO BE THRIVING ALONG ERN EDGE OF THE
LLJ CORE THAT SHOULD BEGIN TO SHIFT WWD AS THE NEXT IMPULSE DIGS
SEWD INTO THE SRN PLAINS.  UNTIL THEN...TSTMS CONTINUING ALONG THE
RETURNING MARINE/WARM FRONT ACROSS NCNTRL/NERN AL MAY PRODUCE
TORNADOES ALONG WITH DAMAGING WINDS.  

GIVEN THE ANTICIPATED SHORT TIME FRAME OF THE LINGERING THREAT...A
NEW WW DOES NOT SEEM NECESSARY.  BUT...A COUPLE OF HOURS EXTENSION
OF THE CURRENT WATCH WOULD BE A VIABLE OPTION.
