The radar
The Laughlin AFB radar (KDFX), 101 km from the middle of the area, began a volume at 07:26 UTC, the scan nearest the moment this went out.
Open the radar archive at this moment
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 severe thunderstorm 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
Del Rio, TX (KDLF), launched 00:00Z, 7.4 hours before the alert went out and 127 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.

HAMPSHIREWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Austin/San Antonio, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 24, 12:52 AM CDT, 1 hour 31 minutes earlier.
Area forecast discussion, Apr 24, 12:52 AM CDT, 1 hour 31 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 1252 AM CDT FRI APR 24 2015 .AVIATION... COMPLEX AVIATION FORECAST WITH RESPECT TO SHRA/TSRA. ONLY THE HRRR IS MOSTLY VERIFYING AT 05Z IN SHOWING SHRA/TSRA FROM RIO GRANDE INTO THE HILL COUNTRY. WILL MAINTAIN TEMPO AT KDRT TO BEGIN THE TAF PERIOD. HAVE VCSH OVERNIGHT AT KAUS/KSAT/KSSF AS SHRA/TSRA MOVE EAST ACROSS OUR AREA. WILL MONITOR RADAR TRENDS FOR UPGRADE TO TEMPOS OR PREVAILING AT THOSE SITES. A LULL IN SHRA/TSRA IS EXPECTED FRIDAY MORNING BEFORE REDEVELOPMENT OCCURS IN THE AFTERNOON INTO EVENING. HAVE MAINTAINED PROB30S AT KAUS/KSAT/KSSF FOR 24/22Z TO 25/02Z. AREAS OF IFR CIGS WILL PREVAIL. HOWEVER... SHRA/TSRA MAY DISRUPT THE LOW CIGS AT TIMES. CIGS RISE TO MVFR BY LATE MORNING AND VFR IN THE AFTERNOON. MVFR CIGS REDEVELOP FRIDAY NIGHT. S TO SE WINDS 5 TO 10 KTS WILL INCREASE TO 10 TO 15 KTS ON FRIDAY. HOWEVER...TSRA WILL CAUSE OUTFLOW WINDS UP TO 40 KTS WITH VRBL DIRECTION. DRYLINE MAY INTRUDE ACROSS FAR NORTHWESTERN AREAS TO CAUSE W TO NW WINDS UP TO 10 KTS THOUGH WILL STAY NW OF TAF SITES. && .PREV DISCUSSION... /ISSUED 747 PM CDT THU APR 23 2015/ UPDATE... SEVERE THUNDERSTORM WATCH 97 WAS JUST CANCELLED DUE TO THE LACK OF CONVECTION. SHORT RANGE HIGH-RESOLUTION MODELS ARE HAVING A TREMENDOUSLY DIFFICULT TIME WITH CONVECTION...GENERALLY CREATING TOO MUCH AND TOO SOON. THAT SAID...WATER VAPOR IMAGERY CLEARLY SHOWS A SHORTWAVE TROUGH EJECTING OUT OVER CHIHUAHUA. COUPLED WITH THE DIURNAL STRENGTHENING OF THE LOW LEVEL JET...WE STILL EXPECT CONVECTION TO INCREASE IN COVERAGE ALONG THE MEXICAN MOUNTAINS AND EVENTUALLY SPREAD ONTO THE RIO GRANDE PLAINS AND POINTS EAST. HOWEVER...THE SCALE AND SCOPE ARE UNCERTAIN. WILL SEND OUT AN UPDATE BY 8 PM...GENERALLY LOWERING POPS...ESPECIALLY BEFORE 06Z...AND RE-TRENDING ALL FORECAST VARIABLES THROUGH 12Z FRIDAY. PREV DISCUSSION... /ISSUED 703 PM CDT THU APR 23 2015/ AVIATION... THE DIFFICULTY IN THE FORECAST IS IDENTIFYING THE CHANCES AND COVERAGE OF THUNDERSTORMS OVER THE NEXT 24 HOURS. IN THE VERY SHORT TERM...ONLY INCLUDED VCTS AT KDRT. AFTER 07Z...PUT TEMPO TSRA AT KDRT...BUT THIS IS SPECULATIVE AND BASED ON THE LATEST HIGH RESOLUTION MODELS...WHICH ARE HAVING A 50-50 SUCCESS RATE WITH STORMS THIS AFTERNOON. OTHERWISE...WE EXPECT THE MAIN ACTIVITY FOR THE I-35 CORRIDOR TAFS TO BE FROM 21Z FRIDAY TO 05Z SATURDAY. WE MAY HAVE TO INCLUDE VRB WIND GUSTS AND VISIBILITY RESTRICTIONS IN LATER TAF ISSUANCES. IN THE MEANTIME...IFR CIGS ARE LIKELY AT THE I-35 SITES FROM 09-17Z. PREV DISCUSSION... /ISSUED 510 PM CDT THU APR 23 2015/ UPDATE... SEVERE THUNDERSTORM WATCH 97 WAS JUST ISSUED. THIS IS A VERY SMALL WATCH AND SOMEWHAT ATYPICAL...BUT THE ONE STORM THAT HAS DEVELOPED APPEARS TO BE TAKING ON SUPERCELLULAR CHARACTERISTICS. IF THIS CONTINUES...THE STORM WILL PASS OVER FAIRLY HIGHLY POPULATED AREAS...AND THE OUTFLOW MAY CAUSE OTHER STORMS TO DEVELOP...WHICH WOULD QUICKLY BECOME SEVERE. PREV DISCUSSION... /ISSUED 325 PM CDT THU APR 23 2015/ SHORT TERM (TONIGHT THROUGH FRIDAY NIGHT)... LATE AFTERNOON SURFACE OBSERVATIONS SHOW THE LEADING EDGE OF THE DRYLINE HAS MIXED EAST OF DRYDEN TO OZONA AS OF 23/19Z. THE LATEST VISIBLE SATELLITE LOOP STILL SHOWS PLENTY OF CLOUDS ACROSS THE REGION. HOWEVER...THE LOW CLOUD COVER WEST OF THE I-35 CORRIDOR IS BEGINNING TO BREAK UP AND THIS HAS ALLOWED TEMPERATURES TO RISE INTO THE 80S. SOME CU IS ALSO VISIBLE WEST OF THE RIO GRANDE AS BREAKS IN THE MID AND HIGH CLOUDS HAVE HELPED TO DESTABILIZE THE LOWER LEVELS. THE HI-RES MODELS TEND TO AGREE IN SHOWING CONVECTION DEVELOPING WEST OF THE RIO GRANDE ALONG THE SERRANIAS DEL BURRO MOUNTAINS BY LATE THIS AFTERNOON. THIS CONVECTION IS THEN EXPECTED TO MOVE EAST AND NORTHEAST INTO THE RIO GRANDE PLAINS AND SOUTHERN EDWARDS PLATEAU GIVEN SFC-6KM SOUTHWESTERLY WINDS OF 24KT ON THE KDRT 12Z SOUNDING. THE OTHER AREA FAVORED FOR CONVECTION WILL BE ACROSS THE WESTERN HILL COUNTRY. ALTHOUGH IT/S TOUGH TO FIND A SURFACE TROUGH...THERE IS SOME WEAK CONVERGENCE NOTED IN THE SURFACE WINDS AS OF 19Z. THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR AREAS GENERALLY ALONG AND WEST OF THE INTERSTATE 35 CORRIDOR TODAY. THE MAIN CONCERN WILL BE LARGE HAIL AND DAMAGING WINDS. PROVIDED CONVECTION DOES DEVELOP THROUGH THIS AFTERNOON AND EVENING...A DEVELOPING LOW-LEVEL JET SHOULD HELP SUSTAIN CONVECTION INTO THE EARLY MORNING HOURS. CONCERNS SHOULD THEN TRANSITION FROM SEVERE THUNDERSTORMS INTO LOCALLY HEAVY RAINFALL DURING THE OVERNIGHT HOURS. THE DAY 1 EXCESSIVE RAINFALL OUTLOOK CONTINUES TO MAINTAIN A SLIGHT RISK FOR AREAS ALONG AND WEST OF I-35 THROUGH TONIGHT. RAINFALL TOTALS OF 1 TO 2 INCHES WITH ISOLATED AMOUNTS UP TO 4 INCHES ARE POSSIBLE. ON FRIDAY...THE WEATHER WILL REMAIN ACTIVE...BUT MUCH WILL LIKELY DEPEND ON THE EXTENT OF CONVECTION TODAY/TONIGHT. THE LATEST DAY2 CONVECTIVE OUTLOOK CONTINUES TO MAINTAIN A SLIGHT RISK FOR SEVERE THUNDERSTORMS ACROSS OUR REGION. WE/LL CONTINUE TO MAINTAIN A GOOD CHANCE FOR STORMS TOMORROW...WITH THE FOCUS LIKELY REMAINING NORTH OF I-10 DURING THE AFTERNOON HOURS. IN ADDITION...A PACIFIC COLD FRONT MAY ALSO SERVE AS A FOCUS FOR CONVECTION ON FRIDAY NIGHT. LONG TERM (SATURDAY THROUGH THURSDAY)... ON SATURDAY...THE PACIFIC COLD FRONT CONTINUES TO MOVE FROM WEST TO EAST ACROSS THE REGION. THIS WILL BRING A DECREASING CHANCE FOR RAINFALL TO OUR REGION. TEMPERATURES WILL ACTUALLY WARM BEHIND THE FRONT AS NORTHWESTERLY...DOWNSLOPE WINDS AID IN THE WARMING PROCESS. SOUTHERLY FLOW BEGINS TO RETURN ON SUNDAY AND CONVERGENCE ALONG THE REMNANT FRONTAL BOUNDARY WILL LEAD TO RAIN CHANCES RETURNING TO THE FORECAST FOR THE CENTRAL AND EASTERN PORTIONS OF OUR REGION. A SECOND PACIFIC COLD FRONT WILL MOVE THROUGH BY LATE MONDAY AND THIS WILL BRING DRIER AND COOLER WEATHER TO THE REGION THROUGH THURSDAY. && .PRELIMINARY POINT TEMPS/POPS...
