AREAS AFFECTED...NORTHERN AL AND SOUTHERN MIDDLE TN
CONCERNING...SEVERE THUNDERSTORM WATCH 374...
VALID 222020Z - 222145Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 374
CONTINUES.
SUMMARY...STRONG/DAMAGING WIND GUST POTENTIAL MAY BE INCREASING
ACROSS NORTHERN ALABAMA INTO SOUTHERN MIDDLE TENNESSEE OVER THE NEXT
1-2 HOURS.
DISCUSSION...A DENSE CLUSTER OF CONVECTION OVER NORTHERN AL/SOUTHERN
MIDDLE TN HAS SHOWN SOME SIGNS OF INTENSIFICATION RECENTLY. IF THIS
AREA OF CONVECTION CAN CONSOLIDATE FURTHER, DAMAGING WIND POTENTIAL
WILL INCREASE IN THE SHORT TERM. THIS ACTIVITY IS OCCURRING WITHIN A
FAVORABLY SHEAR ENVIRONMENT, CHARACTERIZED BY 35 KT 0-6 KM EFFECTIVE
SHEAR AND AROUND 200 M2/S2 0-1 KM SRH. RADAR VELOCITY SIGNATURES
HAVE ALSO INCREASED BOTH IN INTENSITY AND WITH SOME MIDDLE ROTATION
NOTED. GREATER FORWARD PROPAGATION OF THIS CLUSTER MAY BE UNDERWAY
AND AN ENSUING RISK OF SEVERE WIND GUSTS MAY OCCUR SOON. IF THIS
EVOLUTION UNFOLDS, A DOWNSTREAM WATCH MAY BE NEEDED.
