...S THROUGH S CNTRL TX...

BOUNDARY LAYER DEWPOINTS ARE IN THE LOW TO MID 60S OVER THE WRN
GULF...AND THIS PARTIALLY MODIFIED GULF AIR WILL CONTINUE ADVECTING
NWWD THROUGH S TX OVERNIGHT. THE ADVECTION OF MODEST LOW LEVEL
MOISTURE UNDERNEATH PLUME OF STEEPER LAPSE RATES SPREADING NEWD OUT
OF MEXICO WILL CONTRIBUTE TO MUCAPE AROUND 1000 J/KG. FORCING FOR
ASCENT ASSOCIATED WITH A SHORTWAVE TROUGH OVER NRN MEXICO WILL
SPREAD NEWD THROUGH S TX OVERNIGHT. THE LOW LEVEL RESPONSE IS
FORECAST TO REMAIN RELATIVELY WEAK WITH ONLY A MODEST LOW LEVEL JET
AND SURFACE TROUGH EXPECTED ACROSS S TX LATER TONIGHT. FORCING FOR
ASCENT SPREADING NEWD OUT OF MEXICO SHOULD CONDITION THE ATMOSPHERE
FOR STORMS TO DEVELOP LATER THIS EVENING. VERTICAL SHEAR IN THE
LOWEST 2 KM IS NOT EXPECTED TO BE PARTICULARLY STRONG DUE TO
ANTICIPATED MODEST LOW LEVEL JET. HOWEVER...DEEP LAYER SHEAR OF 40
TO 45 KT COULD SUPPORT SOME ORGANIZED STORM STRUCTURES INCLUDING
SUPERCELLS. ACTIVITY MAY EVOLVE INTO AN MCS WITH TIME AS IT
CONTINUES EWD THROUGH S TX TONIGHT. PRIMARY THREATS WILL BE LARGE
HAIL AND ISOLATED DAMAGING WIND.
