STRONG SYNOPTIC SUPPORT FOR HEAVY RAINFALL GIVEN ABUNDANT TROPICAL AIR IN THE LOW LEVELS...BAROCLINIC INSTABILITY ALOFT AND RIGHT REAR QUADRANT JET DYNAMICS. LOW PRESSURE SYSTEM MOVING ACROSS LOWER RIO GRANDE VALLEY WILL ALSO SERVE TO INCREASE UPPER LEVEL DIVERGENCE OVER TIME. MEANWHILE...ON THE FRINGES AND EAST OF THE RAIN SHIELD...GREATER SURFACE BASED INSTABILITY WILL ALLOW FOR MARGINALLY SEVERE THUNDERSTORM DEVELOPMENT. WILL BE INCREASING THE THREAT SLIGHTLY FROM EARLIER HWO TO INDICATE A BRIDGE OVER MINIMAL CRITERIA ON WIND AND HAIL THREAT ALONG WITH LOCALLY HEAVY CONVECTIVE RAINFALL. OTHERWISE...THE POP FORECAST LOOKS GOOD BUT THE TEMPERATURES MAY NEED TO BE ADJUSTED DOWNWARD IN THE RAIN COOLED AREAS. && .LOCAL APPLICATIONS...
