AREAS AFFECTED...FL PENINSULA

CONCERNING...TORNADO WATCH 750...

VALID 132006Z - 132130Z

POTENTIAL FOR ISOLATED TORNADOES CONTINUES ACROSS WW AREA...WITH
GREATEST THREAT OVER THE CNTRL PENINSULA THROUGH 21-22Z.

AS OF 1946Z...TAMPA RADAR IMAGERY SHOWED THE CENTER OF CHARLEY
APPROXIMATELY 25W OF FMY. WHILE INITIAL RAINBAND /COMPOSED AT TIMES
OF SEVERAL SUPERCELLS/ HAS LIFTED N OF A ORL TO MLB
LINE...SUBSEQUENT SUPERCELLS HAVE DEVELOPED IN SMALLER...MORE
TRANSIENT BANDS SW OF TAMPA /NAMELY MANATEE...HARDY...DESOTO AND
HIGHLANDS COUNTIES/. HERE...INFLUX OF MODERATELY UNSTABLE AIRMASS
ALONG THE ERN PENINSULA /I.E. SBCAPES OF 2000-3000 J/KG/ IS
ENCOUNTERING INCREASINGLY SHEARED ENVIRONMENT IN RIGHT FORWARD
QUADRANT OF CHARLEY.

ISOLATED TORNADOES WILL REMAIN POSSIBLE WITH ANY CONVECTIVE ELEMENTS
ACROSS THE WW AREA THROUGH THE REMAINDER OF THE AFTERNOON.
HOWEVER...IT APPEARS THAT THE GREATEST POTENTIAL THROUGH 21 OR 22Z
WILL BE OVER THE CNTRL PENINSULA WHERE STRONGEST LOW-LEVEL SHEAR
WILL BE CO-LOCATED WITH WRN EDGE OF GREATER INSTABILITY.
