NWS STORM PREDICTION CENTER NORMAN OK
1029 AM CST WED MAR 09 2016

AREAS AFFECTED...CNTRL TX COASTAL AREA

CONCERNING...SEVERE THUNDERSTORM WATCH 40...

VALID 091629Z - 091800Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 40
CONTINUES.

SUMMARY...AT LEAST A MODEST THREAT FOR A FEW STRONG TO DAMAGING WIND
GUSTS WILL PERSIST OVER THE CNTRL TX COASTAL AREA THROUGH ABOUT
18Z...BEYOND WHICH TIME THE THREAT SHOULD DECREASE.

DISCUSSION...NUMEROUS THUNDERSTORMS PERSIST GENERALLY ALONG AND EAST
OF A FRONT THAT EXTENDS FROM SRN TX JUST WEST OF BROWNSVILLE NEWD
THROUGH SERN TX. THE WARM SECTOR REMAINS VERY MOIST AND IS
MODERATELY UNSTABLE...BUT THE BOUNDARY LAYER HAS BEEN SLOW TO
DESTABILIZE DUE TO THE ONGOING CLOUDS AND PRECIPITATION...AND THIS
HAS SERVED TO LIMIT OVERALL SEVERE THREAT THUS FAR. ACTIVITY WILL
REMAIN EMBEDDED WITHIN DEEP SLY UNIDIRECTIONAL WIND PROFILES WITH
35-40 KT EFFECTIVE SHEAR...BUT WITH RELATIVELY SMALL LOW-LEVEL
HODOGRAPHS. THIS ENVIRONMENT WILL CONTINUE TO SUPPORT POTENTIAL FOR
A FEW ORGANIZED CELLS WITH A MODEST THREAT FOR DAMAGING WIND AS
ACTIVITY DEVELOPS NWD NEXT COUPLE HOURS.
