AREAS AFFECTED...PORTIONS OF THE CENTRAL GULF COAST AND SOUTHEAST
CONCERNING...TORNADO WATCH 351...354...
VALID 182048Z - 182215Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 351, 354 CONTINUES.
SUMMARY...THE THREAT FOR DAMAGING WIND GUSTS AND A FEW TORNADOES
CONTINUES ACROSS TORNADO WATCHES 351 AND 354.
DISCUSSION...A MODESTLY WELL-ORGANIZED CONVECTIVE LINE REMAINS
ONGOING FROM THE CENTRAL GULF COAST INTO EASTERN ALABAMA AS OF 2035
UTC. WHILE NO SEVERE GUSTS HAVE BEEN OBSERVED OVER THE PAST SEVERAL
HOURS, MODERATE BUOYANCY AND MODESTLY ENHANCED EFFECTIVE SHEAR
PRECEDING THIS CONVECTION WILL CONTINUE TO SUPPORT THE MAINTENANCE
OF THIS CONVECTIVE LINE AND ADDITIONAL CLUSTERS, WITH A THREAT FOR
DAMAGING WIND GUSTS. THIS ACTIVITY WILL SPREAD EAST/NORTHEASTWARD
THROUGH THIS EVENING IN TANDEM WITH A MID-LEVEL DISTURBANCE AND
ATTENDANT SOUTHERLY, LOW-LEVEL JET. THE MXX/EVX/EOX VAD PROFILES ARE
ALSO SAMPLING 125-150 M2/S2 0-500 M SRH AHEAD OF THIS CONVECTION,
WHICH WILL CONTINUE TO PROMOTE THE POTENTIAL FOR A FEW TORNADOES. A
RELATIVELY GREATER TORNADO RISK MAY DEVELOP FROM EASTERN ALABAMA
INTO WESTERN GEORGIA WHERE THE CONVECTIVE LINE IS GRADUALLY
DEVELOPING A MORE FAVORABLE NORTH-SOUTH ORIENTATION (MORE
PERPENDICULAR TO DEEP-LAYER SHEAR VECTORS) AND WHERE SURFACE WINDS
ARE LOCALLY MORE BACKED.
