THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
111...113...114...115...CONTINUES.

ELONGATED SEVERE MCS THAT EXTENDS FROM NRN KY...SWWD INTO NRN AR
CONTINUES MOVING SEWD AS PRECIPITATION/COLD POOL EXPANDS ALONG THE
LOWER OH VALLEY REGION.  RADAR TRENDS INDICATE SEVERAL LONG-LIVED
SUPERCELL STRUCTURES ALONG THIS LINE...ESPECIALLY ACROSS SERN MO
OVER MISSISSIPPI COUNTY AND NERN AR NEAR CLAY/GREENE COUNTIES.
ADDITIONALLY...ISOLATED SUPERCELLS HAVE DEVELOPED OVER ERN KY FROM
HART TO LARUE COUNTIES.  LARGE HAIL SHOULD ACCOMPANY MOST OF THIS
ACTIVITY...WITH GREATEST POTENTIAL FOR ISOLATED TORNADOES WITH THE
LONG LIVED SUPERCELLS/SUSTAINED ROTATIONAL COUPLETS.  GIVEN THE
STEEP LAPSE RATE ENVIRONMENT IN PLACE ACROSS THE TN VALLEY...SFC-3
KM VALUES IN EXCESS OF 8 C/KM...ROBUST UPDRAFTS WILL UNDOUBTEDLY
PERSIST WELL INTO THE EVENING HOURS.
