What happened

The episode as NWS CRP wrote it up.

An upper level trough remained situated out to the west in Northern Mexico and the Southwest U.S. A very unstable airmass developed during the afternoon hours across South Texas triggering thunderstorms. An upper level shortwave rotated out of Mexico during the afternoon providing increasing large-scale ascent, divergence aloft and steepening mid-level lapse rates. Thunderstorms initially began as supercells across the Rio Grande Plains and Duval and Jim Wells counties during the afternoon and early evening, producing large hail and heavy rain. The supercells organized into a squall-line during the evening and moved east across the Coastal Bend, producing heavy rainfall and flash flooding. A wake low formed over the Coastal Bend behind the squall line as it moved into the offshore waters during the late night and early morning hours. High sustained winds of 40 to 50 mph, with some gusts over 60 mph, developed over the Coastal Bend, Victoria Crossroads region and the bays and nearshore waters. Damage associated with these winds was mainly confined to tree limbs, however a tug boat in Port Oconnor was reportedly damaged. See High Wind event entry as well as wind entries under Gulf of Mexico for further information.

.PREVIOUS DISCUSSION...
.SHORT-TERM (TODAY THROUGH MONDAY)...UPPER LEVEL LOW CONTINUES TO
SPIN OVER AZ AND WILL BEGIN TO SLOWLY ADVANCE EAST ON MONDAY.
CURRENTLY AN ELONGATED SHEAR AXIS EXISTS JUST WEST OF THE RIO GRANDE
IN DIFLUENT FLOW ALOFT.  THIS NEXT SPOKE OF ENERGY WILL CONTINUE TO
ADVANCE EAST INTO THE CWA TODAY AND WILL GRADE POPS HIGHEST WEST AND
LOWEST NORTHEAST WHERE LOWER THETA-E AIR WILL RESIDE.  BELIEVE WE
WILL SEE SCATTERED CONVECTION FORMED DURING HEATING TODAY BUT NOT
TOO CONFIDENT ON HEAVY RAINFALL THREAT TODAY.  HOWEVER BY TONIGHT
THAT MAY CHANGE AND DAY SHIFT MAY CONTEMPLATE A FLOOD WATCH.
BELIEVE THAT 30KT LOW LEVEL JET IN CONJUNCTION WITH AXIS OF
INSTABILITY OVER THE CWA MAY PRODUCE TRAINING ECHOS OR ALLOW FOR
UPWIND PROPAGATION OF AN MCS MOVING SE FROM STORMS ORIGINATING
ACROSS THE RIO GRANDE.  WILL MENTION HEAVY RAINFALL IN THE
WEST/CENTRAL ZONES AND PAINT LIKELY POPS IN ALL AREAS.  WEAK
INSTABILITY WITH CAPES ONLY 1000-1500 J/KG WILL LIMIT SEVERE WEATHER
THREAT DESPITE SHEAR PROFILES FAVORABLE FOR SUPERCELLS.  IF WE DO
GET MORE HEATING THAN EXPECTED TODAY...SEVERE WEATHER MAY BE
POSSIBLE OVER THE RIO GRANDE PLAINS THIS EVENING.  WILL BROAD BRUSH
50 PPOS OVER THE AREA MONDAY AS REGION STILL REMAINS IN THE UPPER
DIFLUENT FLOW.  SHEAR WILL CONTINUE TO LOOK GOOD FOR ROTATING
THUNDERSTORMS OVER THE RIO GRANDE PLAINS WHERE INSTABILITY WILL BE
HIGHEST.  SPC HAS THIS AREA IN SLIGHT RISK AND LATER SHIFTS WILL
CONTINUE TO MONITOR.  SCEC EXPECTED TONIGHT AND MONDAY OFFSHORE.

.LONG-TERM (MONDAY NIGHT THROUGH SATURDAY)...LOOKS LIKE RAINFALL
CHANCES WILL CONTINUE THROUGH EARLY TUESDAY...BEFORE THE UPPER LOW
MOVES ACROSS THE AREA AND BRINGS DRIER AIR TO SOUTH TEXAS.  WILL
KEEP CHANCE TO LIKELY POPS MONDAY NIGHT/TUESDAY RESPECTIVELY...WITH
LIKELY POPS OVER THE RIO GRANDE PLAINS LATE MONDAY NIGHT.  THINGS
LOOK TO REMAIN DRY WEDNESDAY AND MOST OF THURSDAY.  GFS IS BRINGING
ANOTHER FRONT ACROSS THURSDAY EVENING...MUCH EARLIER THAN 24 HOURS
AGO.  SEEMS UKMET AND CANADIAN ARE FAIRLY SIMILAR WITH GFS SO WILL
GO WITH THIS SCENARIO (ALSO...MODELS HAVE BEEN SLOW/HAVING HARD TIME
