CONCERNING...TORNADO WATCH 129...

VALID 042046Z - 042145Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 129 CONTINUES.

SUMMARY...SEVERE THREAT CONTINUES ACROSS WW 129...WITH THE GREATEST
SHORT-TERM THREAT ACROSS THE WRN PORTION OF THE WATCH.

DISCUSSION...AN INTENSE SUPERCELL NEAR THE JEFF DAVIS/REEVES COUNTY
BORDER WILL LIKELY BE THE GREATEST SHORT-TERM THREAT ACROSS WW 129.
MODERATE INSTABILITY AND A FAVORABLY VEERING WIND PROFILE WILL
CONTINUE TO SUPPORT A DISCRETE SUPERCELL MODE...AND A WEAK
CONFLUENCE ZONE EVIDENT ON VIS IMAGERY IN THE VICINITY OF THIS CELL
MAY LOCALLY ENHANCE A BRIEF TORNADO THREAT.

ADDITIONAL STORM INITIATION IS POSSIBLE ACROSS THE WATCH AREA LATER
THIS AFTERNOON AS LARGE-SCALE ASCENT SLOWLY SPREADS EWD AHEAD OF A
STRONG UPPER TROUGH OVER THE SOUTHWEST. LOW-LEVEL SHEAR WILL LIKELY
INCREASE SOMEWHAT LATE THIS AFTERNOON INTO EARLY EVENING...WHICH
WILL ENHANCE THE TORNADO POTENTIAL WITH ANY DISCRETE SUPERCELLS THAT
CAN BE MAINTAINED.
