The episode as NWS BRO wrote it up.
A weak boundary over the northern Gulf of Mexico combined with the remnants of Odile over NW Texas. Daytime heating during the afternoon and the deep moisture (indicated by precipitable waters of 2 inches) allowed for scattered showers to develop over the lower and middle Valley. Periods of heavy rain fell across the region, with over an inch of rain falling in less than 30 minutes in McAllen.

ANOTHER AREA OF FOCUS THIS AFTERNOON IS THE CONVECTION OVER THE SIERRA MADRE EARLY THIS MORNING. THE CONVECTION HAS DIMINISH BUT A VERY VISIBLE MCV CAN BE NOTED ON VISIBLE SATELLITE. THE GFS/ECMWF ARE SHOWING AN INCREASE IN DEVELOPMENT OF SHOWERS ACROSS THE WESTERN COUNTIES AND AN INCREASE IN POPS...HOWEVER...THE LAST FEW DAYS THERE HAS NOT BEEN MUCH DEVELOPMENT DUE TO SUBSIDENCE FROM THE UPPER LEVEL HIGH OVER THE AREA. LEFT INHERITED 30 PERCENT POP ACROSS THE CWA FOR THE REST OF THIS AFTERNOON AS THERE IS SOME UNCERTAINTY EXACTLY IF THIS MCV COULD ENHANCE THAT MUCH CONVECTION OVER THE AREA.

MODEL GUIDANCE POPS REMAIN RATHER HIGH BUT WITH NO OTHER SUBSTANTIAL FOCUS FOR CONVECTION WILL CONTINUE TO FORECAST BELOW GUIDANCE WHICH OVERALL REMAINS IN THE 25-35 PERCENT RANGE. AS THE DRIER AIR MOVES IN SUNDAY AND MONDAY PWAT VALUES DROP CONSIDERABLY MEAN RH VALUES BETWEEN 800-500MB FALL TO AROUND 20 PERCENT. THIS SHOULD CUT OFF OUR RAIN CHANCES FOR AT LEAST 36-48 HOURS. WINDS BEGIN TO VEER SOUTHEAST TUES BUT IT WILL TAKE ABOUT ANOTHER 24 HOURS BEFORE SUFFICIENTLY DEEP MOISTURE RETURNS TO THE REGION. WED-FRI WE WILL SEE THE MOISTURE RETURN TO THE REGION AND RAIN CHANCES INCREASING BACK TO SEASONAL NORMALS.
