CONCERNING...TORNADO WATCH 516

VALID 060535Z - 060730Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 516 CONTINUES.

SUMMARY...THE THREAT FOR DAMAGING WINDS AND A COUPLE TORNADOES
CONTINUES...AND IS EXPECTED TO INCREASE SOMEWHAT IN THE 06Z-10Z TIME
FRAME AS AN UPTICK IN THUNDERSTORM COVERAGE IS ANTICIPATED.

DISCUSSION...LATEST MESOANALYSIS SHOWED A COLD FRONT EXTENDING SOUTH
FROM A SURFACE LOW OVER SOUTHWEST MS INTO THE CENTRAL GULF OF
MEXICO.  A QUASI-STATIONARY FRONTAL BOUNDARY EXTENDED FROM NEAR
BOOTHVILLE...LA EAST-NORTHEAST ACROSS THE FL PANHANDLE AND INTO FAR
SOUTHERN GA.  LITTLE DISCERNIBLE NORTHWARD MOTION HAS OCCURRED WITH
THIS FRONT OVER THE PAST FEW HOURS...AND ANY NORTHWARD SHIFT OVER THE
NEXT FEW HOURS WILL LIKELY BE MODEST AND PRIMARILY OVER SOUTHERN GA.

DATA FROM A SUPPLEMENTAL 04Z UPPER-AIR SOUNDING AT TALLAHASSEE
REVEALED 0-1 KM AND DEEP-LAYER SHEAR OF 31 KTS AND 44 KTS...
RESPECTIVELY...AND WEAK SURFACE-BASED INSTABILITY.
IN ADDITION VWP DATA FROM THE KVAX WSR-88D SAMPLED SUBSTANTIAL
LOW-LEVEL HODOGRAPH CURVATURE AND 35-40 KTS OF 0-1 KM SHEAR.

THUNDERSTORMS OVER THE NORTHEAST GULF SOUTH OF TALLAHASSEE WILL
CONTINUE TO MOVE INLAND OVER THE NEXT FEW HOURS WHILE ADDITIONAL
STORMS FORM OVER THE DISCUSSION AREA AS FORCING FOR ASCENT
ASSOCIATED WITH AN UPPER-LEVEL LOW NEAR THE TX-LA BORDER INCREASES.
STORMS ALONG THE COLD FRONT MAY ALSO INTENSIFY AS THE FRONT MOVES
STEADILY EAST INTO WESTERN PORTIONS OF THE WW.  BOWING LINE SEGMENTS
WITH EMBEDDED CIRCULATIONS WILL POSE A RISK FOR DAMAGING WINDS AND
ALSO A TORNADO THROUGH THE EARLY MORNING HOURS.
