AREAS AFFECTED...E CNTRL/SRN AL...W CNTRL/SW GA AND THE FL PNHDL
CONCERNING...SEVERE THUNDERSTORM WATCH 143...
VALID 051812Z - 051945Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 143
CONTINUES.
A NEW WW MAY BE NEEDED EAST OF WW 143...ACROSS PARTS OF GEORGIA AND
NORTHERN FLORIDA...WITHIN THE NEXT HOUR OR TWO.
THE LOWER/MID TROPOSPHERIC CYCLONIC CIRCULATION...ASSOCIATED WITH
THE MESOSCALE CONVECTIVE SYSTEM NOW SPREADING ACROSS/EAST OF
BIRMINGHAM/MONTGOMERY AND ADJACENT AREAS OF CENTRAL/SOUTHERN
ALABAMA...IS MIGRATING EASTWARD AROUND 35 KTS. THIS FEATURE APPEARS
LIKELY TO PROGRESS ACROSS EAST CENTRAL ALABAMA INTO WEST CENTRAL
GEORGIA...NORTH OF COLUMBUS...BETWEEN NOW AND 20-21Z... AND SHOULD
MAINTAIN VIGOROUS CONVECTIVE DEVELOPMENT IN THE PRESENCE OF WEAK TO
MODERATE CAPE AND STRONG DEEP LAYER SHEAR. WITH THE WEAK AND
WESTERLY COMPONENT TO THE LOW-LEVEL WIND FIELDS ...IN ADDITION TO
TEMPERED BOUNDARY LAYER WARMING...REMAINING A LIMITING FACTOR TO A
MORE SUBSTANTIVE SEVERE WEATHER THREAT...IT IS NOT CERTAIN THAT
THERE WILL BE MUCH INTENSIFICATION IN THE NEAR TERM.
HOWEVER...PERIODIC STRONGER UPDRAFT PULSES PROBABLY WILL REMAIN
CAPABLE OF PRODUCING SEVERE HAIL...AND THE RISK FOR AT LEAST
LOCALIZED CONVECTIVELY ENHANCED SURFACE WIND GUSTS WILL CONTINUE.
