AREAS AFFECTED...WCNTRL AND CNTRL TX

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 251859Z - 252030Z

...SEVERE THUNDERSTORM WATCH MAY BE REQUIRED BY 21Z...

COMPLEX SFC PATTERN HAS EVOLVED ACROSS NORTH TX EARLY THIS
AFTERNOON.  ONGOING MCS CONTINUES ITS SEWD MOVEMENT INTO NERN TX
WITH STRONG PRESSURE RISES IN ITS WAKE ACROSS SWRN OK/ERN TX
PANHANDLE.  RESULTANT SFC BOUNDARY/CONVERGENCE SHOULD SHARPEN NEAR
I-20 CORRIDOR WEST OF FTW...WWD TOWARD ABI OVER THE NEXT FEW HOURS. 
IT APPEARS BOUNDARY LAYER AIRMASS WILL FURTHER DESTABILIZE AND
BECOME WEAKLY CAPPED ALLOWING CONVECTIVE DEVELOPMENT ALONG THIS ZONE
NEAR OR SHORTLY AFTER 21Z.  IN ADDITION...DEEP LAYER SHEAR IS
BECOMING INCREASINGLY SUPPORTIVE OF ROTATING STORMS GIVEN THE MODEST
NWLY FLOW ALOFT THAT HAS DEVELOPED BEHIND THE MCS.  ISOLATED
SUPERCELLS ARE POSSIBLE EARLY...HOWEVER STORM EVOLUTION WILL LIKELY
BECOME AN MCS AS IT PROPAGATES SWD ACROSS THE EDWARDS PLATEAU/HILL
COUNTRY AFTER 26/00Z.  LARGE HAIL CAN BE EXPECTED BEFORE DAMAGING
WIND THREAT INCREASES WITH MORE ORGANIZED CLUSTER.
