CONCERNING...TORNADO WATCH 103...
VALID 062005Z - 062130Z
CORRECTED FOR WATCH TYPE
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 103 CONTINUES.
AN ISOLATED TORNADO THREAT AND HAIL POTENTIAL WILL CONTINUE ACROSS
WW 103 OVER THE NEXT FEW HOURS. NEW WW ISSUANCE IS NOT ANTICIPATED
ATTM.
LATEST SFC ANALYSIS SHOWS A SHALLOW COLD FRONT ADVANCING SLOWLY SWD
ACROSS THE TX COASTAL PLAIN. INSTABILITY HAS CONTINUED TO INCREASE
EARLY THIS AFTERNOON ALONG THE SOUTHEASTERN EDGE OF THE BOUNDARY AND
SBCAPE VALUES NOW RANGE FROM 1000 TO 1500 J/KG FROM THE HOUSTON AREA
SWWD ACROSS MOST OF THE TX COASTAL PLAIN. A LINE OF STRONG
THUNDERSTORMS LOCATED ALONG THE COLD FRONT NEAR VICTORIA WILL
CONTINUE TO MOVE EWD AND SHOULD POSE A SEVERE THREAT INTO THE
IMMEDIATE COASTAL AREAS LATE THIS AFTERNOON. STEEP MID-LEVEL LAPSE
RATES AND COLD AIR ALOFT WILL SUPPORT HAIL WITH THE STRONGER CORES.
LOW-LEVEL SHEAR ON WSR-88D VWPS SHOULD ALSO BE STRONG ENOUGH FOR AN
ISOLATED TORNADO THREAT WITH ROTATING STORMS. THE GREATEST TORNADO
THREAT APPEARS TO BE NEAR CORPUS CHRISTI WHERE MOISTURE EXISTS
THROUGH A DEEPER LAYER AND STORMS ARE MORE DISCRETE IN NATURE.
