WHILE THE AIR MASS REMAINS OVER THE REGION REMAINS FAIRLY UNSTABLE...LACK OF FORCING AT THE SURFACE COUPLED WITH THE BRUNT OF THE UPPER TROUGH LAGGING BACK ACROSS SE TEXAS SHOULD KEEP MOST OF THE TSTM ACTIVITY IN CHECK THROUGH TONIGHT ALTHOUGH A FEW OF THE STRONGER COULD BRING SOME LOCALLY HEAVY RAIN. AT THIS TIME...BECAUSE THE UPPER TROUGH IS NOT PROGRESSING EASTWARD AS PREVIOUS MODEL RUNS SUGGESTED...THE ASSOCIATED SURFACE BOUNDARY LOOKS TO HAVE STALLED JUST WEST OF THE CWA/PWA.
