NWS STORM PREDICTION CENTER NORMAN OK
0348 PM CDT SUN MAY 29 2005

AREAS AFFECTED...CENTRAL TX

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 292048Z - 292215Z

...SEVERE THUNDERSTORM WATCH MAY BE REQUIRED FOR PORTIONS OF CENTRAL
TX...

THUNDERSTORMS ARE SLOWLY INTENSIFYING ALONG DEEP LAYER WIND SHIFT
FROM EAST OF SJT TO WEST OF SEP.  ALTHOUGH NOT PARTICULARLY
UNSTABLE...BOUNDARY LAYER IS MOISTENING ALONG I-35 CORRIDOR INTO
CNTRL TX WHERE SFC DEW POINTS HAVE RISEN INTO THE MID 60S.  OF MORE
CONCERN IS THE APPARENT OUTFLOW BOUNDARY THAT ARCS FROM MCLENNAN
COUNTY...SWWD TO LLANO COUNTY WHERE AN INTENSIFYING UPDRAFT IS
NOTED. AIRMASS IS MUCH MORE UNSTABLE ALONG THIS SRN WIND SHIFT AND
WILL LIKELY ENHANCE THUNDERSTORM DEVELOPMENT OVER THE NEXT FEW
HOURS. WEAKER DEEP LAYER SHEAR PROFILES FAVOR MULTI-CELL OR PERHAPS
SUPERCELL DEVELOPMENT IN SERN PORTIONS OF THE REGION.  LARGE HAIL
SHOULD BE THE PRIMARY SEVERE THREAT.
