MESOSCALE DISCUSSION 0448
NWS STORM PREDICTION CENTER NORMAN OK
0412 AM CDT SAT APR 25 2015

AREAS AFFECTED...FAR EAST-CENTRAL MS AND SOUTHERN AL/WESTERN FL
PANHANDLE

CONCERNING...TORNADO WATCH 106...

VALID 250912Z - 251015Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 106 CONTINUES.

SUMMARY...DAMAGING WIND/ISOLATED TORNADO POTENTIAL WILL CONTINUE
MAINLY FROM FAR EAST-CENTRAL MS INTO PORTIONS OF
SOUTHWEST/SOUTH-CENTRAL AL EARLY THIS MORNING...WHILE STORMS COULD
ALSO INCREASE/POSE A SEVERE RISK ACROSS FAR SOUTHEAST MS/FAR
SOUTHERN AL/WESTERN FL PANHANDLE. TORNADO WATCH 106 CONTINUES UNTIL
13Z...AND DOWNSTREAM TRENDS WILL CONTINUE TO BE MONITORED FOR A
POSSIBLE ADDITIONAL WATCH.

DISCUSSION...A FAST-MOVING SQUALL LINE CONTINUES TO STEADILY
PROGRESS EASTWARD ACROSS CENTRAL AL AND FAR
EAST-CENTRAL/SOUTH-CENTRAL MS AS OF 09Z/400AM CDT. THE INTEGRITY OF
THE CONVECTIVE LINE/EMBEDDED BOWING STRUCTURES APPEARS TO BE
WEAKENING WHILE INFRARED SATELLITE SATELLITE IMAGERY SHOWS A
DISTINCT CLOUD-TOP WARMING TREND OVER THE PAST FEW HOURS. WHILE THE
SEVERE POTENTIAL IS LIKELY WELL PAST ITS PEAK IN TORNADO WATCH
106...ISOLATED DAMAGING WINDS/TORNADO RISK WILL REMAIN A CONCERN
WITH THE SQUALL LINE OVER THE NEXT HOUR OR TWO. THIS IS PARTICULARLY
GIVEN THAT THE BOUNDARY LAYER CONTINUES TO WARM/MOISTEN EARLY THIS
MORNING ACROSS SOUTHERN AL VIA THE WARM FRONT WHILE ENVIRONMENTAL
VERTICAL SHEAR IS VERY STRONG. IT IS ALSO POSSIBLE THAT
ADDITIONAL/MORE RECENT THUNDERSTORM DEVELOPMENT ACROSS FAR SOUTHEAST
MS COULD INTENSIFY AND POTENTIALLY POSE A SEVERE/POSSIBLE TORNADO
RISK INTO SOUTHWEST AL/WESTERN FL PANHANDLE EARLY THIS MORNING.
