The radar

The Austin/San Antonio radar (KEWX), 25 km from the middle of the area, began a volume at 21:51 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Corpus Christi, TX (KCRP), launched 12:00Z, 9.9 hours before the alert went out and 228 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Apr 4, 11:58 AM CDT, 4 hours 53 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
1158 AM CDT SUN APR 4 2004

.DISCUSSION...
EXPANDED FLASH FLOOD WATCH TO INCLUDE REAL...UVALDE...DIMMIT...AND
ZAVALA COUNTIES...IN ADDITION TO VAL VERDE...EDWARDS...KINNEY...AND
MAVERICK COUNTIES.

AREA OF RAIN OVER WEST PART OF SOUTH CENTRAL TEXAS CONTINUE TO
EVOLVE EASTWARD TODAY.  CHANCE OF RAIN REMAINS HIGH THROUGH MONDAY
NIGHT.  MENTIONED LOCALLY HEAVY RAIN WEST PART OF AREA TODAY AND
OVER SOUTH CENTRAL TEXAS FOR MONDAY AND MONDAY NIGHT...IN ADVANCE
OF UPPER LEVEL LOW.

FORECASTS BEGIN TO TAKE LOW OVER AREA LATE TUESDAY/TUESDAY NIGHT...
IN SIMILIAR TREND TO WHAT HAPPENED LAST FRIDAY.  EXPECT GOOD CHANCE
OF RAIN AHEAD OF THIS SYSTEM...MAINLY MONDAY AND MONDAY NIGHT.

CHANCE OF RAIN DECREASES MARKEDLY BY WEDNESDAY...FOLLOWED BY LOW
POPS LATE IN THE WEEK.

.PREVIOUS DISCUSSION...
ONGOING CONVECTION OVER THE MEXICAN MOUNTAINS WILL SHIFT SLOWLY
EAST TOWARDS THE RIO GRANDE RIVER WHILE TRAINING NORTHWARD ACROSS
VAL VERDE COUNTY. HAVE ISSUED A FLOOD WATCH UNTIL 8 AM FOR VAL
VERDE...EDWARDS...KINNEY AND MAVERICK COUNTIES. LATEST SHORT WAVE
ROTATING AROUND UPPER LOW CENTERED SOUTH OF TUCSON INTERACTING
WITH UPSLOPE FLOW TO GENERATE THE CONVECTION. 00Z DRT SOUNDING AND
KDFX VAD WINDS INDICATE THE STEERING WINDS WILL MOVE THE STORMS
NORTH NORTHEAST. EXPECT THIS ROUND OF CONVECTION TO WEAKEN BY
SUNRISE. 00Z MESOETA SOLUTION INDICATES CONVECTION WILL RE-FIRE THIS
AFTERNOON WEST OF THE RIO GRANDE AND THEN MOVE NORTHEAST ACROSS THE
CWFA DURING THE AFTERNOON AND EVENING HOURS.

THE UPPER LOW CENTERED SOUTH OF TUCSON WILL REMAIN QUASI-STATIONARY
THRU MONDAY. THIS FEATURE WILL SLOWLY LIFT OUT TO THE EAST NORTHEAST
MONDAY NIGHT AND TUESDAY. SHORT WAVES ROTATING AROUND THE CIRCULATION
CENTER WILL TRIGGER ROUNDS OF CONVECTION ACROSS THE CWFA TODAY THRU
TUESDAY. TIMING OF THESE SHORT WAVES AND ASSOCIATED BANDS OF
CONVECTION ARE ALWAYS A PROBLEM AND USUALLY NOT HANDLED WELL BY THE
MODEL SOLUTIONS. LOCALLY HEAVY RAINFALL WILL OCCUR WITH THE STRONGER
STORMS AND ADDITIONAL FLOOD WATCHES MAY BE ISSUED OVER THE NEXT
72HRS. THE GFS SOLUTION OPENS UP THE CLOSED LOW INTO A SLIGHTLY
NEGATIVELY TILTED TROF ON TUESDAY. THIS MAY RESULT IN SEVERE WEATHER
ACROSS THE CWFA ON TUESDAY.

WEDNESDAY LOOKS DRY WITH THE FINAL EXIT OF THE UPPER LOW. A FROPA IS
FCST FOR THURSDAY NIGHT AS AN UPPER TROF DIVES SOUTH ACROSS THE
NORTHERN PLAINS.
