FAR NORTHEAST MS
CONCERNING...SEVERE THUNDERSTORM WATCH 517...
VALID 270406Z - 270530Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 517
CONTINUES.
SUMMARY...ISOLATED DAMAGING WIND WILL REMAIN POSSIBLE INTO THE EARLY
MORNING HOURS.
DISCUSSION...A LONG-LIVED STORM CLUSTER CONTINUES TO MOVE SOUTHWARD
ACROSS PARTS OF WESTERN/MIDDLE TN LATE THIS EVENING. SOME WEAKENING
HAS BEEN NOTED OVER THE LAST 1-2 HOURS, AND A GRADUAL WEAKENING
TREND IS EXPECTED TO CONTINUE, DUE TO WEAK LOW-LEVEL FLOW AND WEAKER
DEEP-LAYER FLOW/SHEAR WITH SOUTHWARD EXTENT. HOWEVER, VERY RICH
LOW-LEVEL MOISTURE CONTINUES TO SUPPORT STRONG TO EXTREME BUOYANCY,
WITH DOWNSTREAM MLCAPE IN THE 3000-4000 J/KG RANGE. THIS BUOYANCY
MAY AID IN OCCASIONAL UPDRAFT INTENSIFICATION ALONG THE GUST FRONT,
AND A CONTINUATION OF AT LEAST AN ISOLATED DAMAGING-WIND THREAT INTO
THE EARLY OVERNIGHT HOURS ACROSS NORTHERN AL AND FAR NORTHEAST MS.
