AREAS AFFECTED...NERN AL/NW GA
CONCERNING...TORNADO WATCH 195...
VALID 270026Z - 270200Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 195 CONTINUES.
LIMITED THREAT CONTINUES ACROSS WW 195. A SEGMENT OF THE SYNOPTIC
FRONT/WIND SHIFT NOW EXTENDS JUST EAST BHM AND IT APPEARS FROM RADAR
THAT NEW CELLS ARE TRYING TO FORM AHEAD OF THIS BOUNDARY. THE LARGE
SCALE FORCING IS BECOMING LESS FAVORABLE FOR STORMS...AS THE UPPER
LOW PULLS AWAY FROM THE AREA AND 500MB TEMPS CONTINUE TO WARM.
HOWEVER...A NARROW AXIS OF INSTABILITY EXTENDS FROM NERN AL THROUGH
TN...WHERE MLCAPE VALUES EXCEED 500 J/KG. IN ADDITION...THE
KINEMATIC PROFILES ARE SUPPORTIVE OF LOW LEVEL MESOCYCLONES AS NOTED
BY LONG LIVED CELL THAT PRODUCED SOME WIND DAMAGE IN CHEROKEE CO
EARLIER THIS EVENING. THAT PARTICULAR CELL HAS WEAKENED...BUT VAD
WIND DATA FROM NEAR ATLANTA SUGGESTS LOW LEVEL ROTATION WILL REMAIN
POSSIBLE WITH ANY ADDITIONAL STORMS THAT ARE ABLE TO ROOT THEMSELVES
IN THE BOUNDARY LAYER.
