MESOSCALE DISCUSSION 1986
NWS STORM PREDICTION CENTER NORMAN OK
0649 AM CDT MON OCT 25 2010

AREAS AFFECTED...FAR ERN TN/WRN CAROLINAS/NRN AND WRN GA/PARTS OF
SRN AND ERN AL

CONCERNING...TORNADO WATCH 711...712...

VALID 251149Z - 251345Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 711...712...CONTINUES.

BROKEN LINE OF STORMS CONTINUES MOVING QUICKLY EWD ACROSS THE SRN
APPALACHIANS REGION. WHILE OVERALL THE CONVECTION IS SHIFTING INTO
AREAS OF WEAKER INSTABILITY...FAVORABLE LARGE-SCALE ASCENT IN
ADVANCE OF THE FAST-MOVING UPPER FEATURE NOW CROSSING WRN TN IS
HELPING TO SUSTAIN ACTIVE/ORGANIZED STORMS.

GIVEN FAVORABLE DEEP-LAYER WIND FIELD RESIDING ACROSS THE
SOUTHEAST...ISOLATED SEVERE/TORNADO THREAT IS FORECAST TO CONTINUE.
WHILE GREATER INSTABILITY -- AND THUS SEVERE POTENTIAL -- EXISTS
FROM GA SWWD...ISOLATED THREAT ASSOCIATED WITH STORMS NEARING THE
ERN FRINGE OF WW 712 ACROSS THE WRN CAROLINAS COULD REQUIRE
ADDITIONAL WW ISSUANCE.
