CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 271916Z - 272115Z

...INCREASING THREAT FOR STRONG/SEVERE WINDS NEXT 1-2 HOURS...

SQUALL LINE EXTENDING FROM GLH/TVR/HEZ IS MOVING E/NEWD AROUND 35 KT
INTO MODERATELY UNSTABLE AIRMASS ACROSS SRN/CNTRL MS...WITH MLCAPE
VALUES AROUND 1500 J/KG. RECENT GUST TO 46 KT AT TVR HAS BEEN THE
STRONGEST GUST SO FAR ON THE LEADING EDGE OF THE LINE...AND THESE
STORMS WILL CONTINUE TO POSE A THREAT FOR DAMAGING WINDS. EARLIER
JACKSON SOUNDING AND CURRENT VAD WIND DATA SUGGESTS ABOUT 30-35 KT
OF MAINLY UNIDIRECTIONAL WLY FLOW THROUGH A DEEP LAYER. SYSTEM HAS A
WELL DEVELOPED COLD POOL...AND THE COMBINATION OF FORWARD
PROPAGATION AND ENVIRONMENTAL FLOW WILL SUSTAIN THE MCS FOR THE NEXT
SEVERAL HOURS. 

A WW MAY BE REQUIRED SHORTLY.
