Virtually no rainfall over the last 15 days of July for the coastal sections of Willacy and Cameron County left a mark on the drought, with the temporary improvement to Moderate (D1) conditions produced by end of June rainfall and a few sea breeze showers into mid July erased by month's end.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS BRO wrote it up.

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Brownsville, TX wrote its last area forecast discussion before the first event at Jul 30, 11:22 PM CST, 38 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE BROWNSVILLE TX 1222 AM CDT TUE JUL 31 2012 .DISCUSSION...UPDATED FOR LATEST AVIATION DISCUSSION BELOW. && .AVIATION...NO AVIATION FORECAST THROUGH 24 HOURS.

AVIATION... FLIGHT CATEGORIES SHOULD REMAIN VFR ACROSS AREA TERMINALS THROUGH 01/0000 UTC. GUSTY SE-S WINDS SHOULD SUBSIDE AFTER SUNSET...WITH LIGHT/VARIABLE WINDS ANTICIPATED OVERNIGHT. DAYTIME HEATING OF A MOIST AIRMASS SHOULD ALLOW A FEW CU TO DEVELOP AGAIN TUESDAY...AS SE-S WINDS INCREASE TO 15 KTS OR SO. /BUTTS/ PREV DISCUSSION... /ISSUED 154 PM CDT MON JUL 30 2012/ SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT/...THE LATEST VSBL SATL IMAGERY AND SURFACE OBS INDICATES THAT THE SEA BREEZE BOUNDARY IS STARTING TO PUSH TOWARDS THE HIGHWAY 77 CORRIDOR. SO FAR THE KBRO RADAR SHOWS NO CELLS FIRING ALONG THIS BOUNDARY. THE BIG QUESTION WILL BE IF THERE WILL BE ENOUGH INSTABILITY NEAR AND TO THE WEST OF THE BOUNDARY FOR ANY CONV TO FIRE OVER THE NEXT SEVERAL HOURS. THE LATEST LAPS CAPE FIELDS SHOW SOME DECENT INSTABILITY POOLED ALONG AND EAST OF HIGHWAY 77 WITH VERY STABLE VALUES LOCATED TO THE WEST OF THE HIGHWAY. SO THE WINDOW OF OPPORTUNITY FOR ANY CONV WILL BE STEADILY CLOSING AS THIS SURFACE BOUNDARY MOVES TOWARDS THE LOWER CAPE NUMBERS. SO BELIEVE NO REAL CONV WILL FIRE ALONG THIS BOUNDARY AND ANY THAT DOES FORM WILL BE VERY ISOLD AND SHORT LIVED. 500 MB RIDGING WILL REMAIN ENTRENCHED OVER THE SOUTH CENTRAL PLAINS STATES AND DEEP SOUTH TX WHICH WILL MAINTAIN TEMPS ABOVE CLIMO AND POPS BELOW CLIMO THROUGHOUT THE SHORT TERM. THE SEA BREEZE TOMORROW WILL LIKELY STRUGGLE TO PRODUCE ANYTHING SIGNIFICANT DUE TO CONTINUED LACKING DEEP LAYER MOISTURE AND INSTABILITY. MAV AND MET TEMPS ARE IN PRETTY GOOD AGREEMENT THROUGHOUT THE SHORT TERM WITH THE MET HIGH TEMPS SHOWING THEIR USUAL WARM BIAS OVER THE MAV NUMBERS. WILL GO CLOSE TO THE MAV/MET CONSENSUS FOR MINS AND WILL GO A FEW DEGREES ABOVE THE MET HIGH TEMPS FOR TOMORROW AS THESE HAVE BEEN VERIFYING BETTER DURING THE SUMMERTIME HEAT. LONG TERM /WEDNESDAY THROUGH MONDAY/...MID LEVEL HIGH WILL STAY IN CONTROL OF THE WEATHER PATTERN THROUGH SATURDAY CHARACTERIZED BY HOT AFTERNOON HIGH TEMPERATURES AND DRY CONDITIONS. THE RIDGE WILL WEAKEN SLIGHTLY AS A MID LEVEL TROUGH RIDES OVER THE RIDGE FRI/SAT. THE RIDGE WILL STRENGTHEN ONCE AGAIN AND SHIFT SLIGHTLY WESTWARD BY THE END OF THE PERIOD. TO VARYING DEGREES THE GFS AND EC ADVERTISE AN INVERTED TROUGH SLOWLY RETROGRADING WESTWARD THROUGH THE GULF. ONE CHANGE OF NOTE IS IT SEEMS THE MODELS ARE SLOWER IN BRINGING THE FEATURE INTO OUR AREA. THEREFORE...HAVE DECREASED POPS IN THE SATURDAY PERIODS. MID LEVEL MOISTURE DOES INCREASE SUN/MON WITH PWATS NEAR 2 INCHES..AND WITH THE TROUGH IN THE AREA...HAVE SLIGHT CHANCE POPS DURING THIS TIMEFRAME. MARINE....TONIGHT THROUGH TUESDAY NIGHT...A FAIRLY LIGHT PG WILL PREVAIL ALONG THE LOWER TX COASTLINE THROUGHOUT THE SHORT TERM AS THE INTERACTION BETWEEN THE INLAND SURFACE TROFFING AND THE GULF RIDGING REMAINS FAIRLY BENIGN. THIS WILL KEEP BOTH THE BAY AND GULF CONDITIONS BELOW SCA LEVELS THROUGHOUT THE SHORT TERM. THE CONDITIONS OVER THE BAY WATERS WILL LIKELY BE THE CHOPPIEST BY TOMORROW AFTERNOON DURING THE USUAL DIURNAL EFFECTS. WEDNESDAY THROUGH SATURDAY...LIGHT TO MODERATE SOUTHEAST WINDS WILL PERSIST THROUGH THE PERIOD AS HIGH PRESSURE WILL REMAIN ANCHORED IN THE NORTHERN GULF OF MEXICO. SEAS WILL REMAIN LOW BUT LOOK TO INCREASE LATE IN THE PERIOD. && .BRO WATCHES/WARNINGS/ADVISORIES... TX...NONE.

2 drought. Local standard time, as filed.
Locally heavy rainfall at the end of June and again near mid month (just under 2 inches at Bayview between the 13th and 15th) was no match for hot, breezy, and rain-free conditions to close out July. The lack of precipitation in a normally wetter region deteriorated drought conditions to Severe (D2) along the Cameron County coast by July 31st.
Locally heavy rainfall at the end of June and again near mid month (just under 2 inches at Bayview, less than 15 miles south of the Cameron/Willacy border between the 13th and 15th) was no match for hot, breezy, and rain-free conditions to close out July. At Port Mansfield, less than 0.05 inches fell after the 15th. The lack of precipitation in a normally wetter region deteriorated drought conditions to Severe (D2) along the Willacy County coast by July 31st.
