$$What 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 May 1, 6:31 PM CDT, 1 hour 52 minutes earlier.
Area forecast discussion, May 1, 6:31 PM CDT, 1 hour 52 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 631 PM CDT WED MAY 1 2013 .AVIATION... A STRONG COLD FRONT WAS PUSHING SOUTHWARD INTO THE SOUTH PLAINS AND WILL ARRIVE IN THE TX HILL COUNTRY BY 05Z AND INTO THE I35 CORRIDOR BETWEEN 10 AND 12Z. VFR CONDITIONS GENERALLY PREVAILING AHEAD OF THE COLD FRONT...HOWEVER SCT TSRA...SOME SEVERE WILL PRECEDE THE COLD FRONT ACROSS THE NRN HILL COUNTRY/RIO GRANDE PLAINS THIS EVENING...MOVING SOUTHWARD INTO SRN/ERN HILL COUNTRY BY 05Z. GUSTY NLY WINDS OF 20-30 KNOTS WITH HIGHER GUSTS WILL DEVELOP BEHIND THE COLD FRONT ALONG WITH MVFR CIGS DEVELOPING IN THE COLDER AIR AND PREVAILING ALONG WITH SCT SHRA/TSRA WITH OCCASIONAL IFR CIGS AND VSBYS IN THE STORMS. LOW LEVEL WIND SHEAR IS POSSIBLE FOR AN HOUR OR TWO JUST AFTER THE SHALLOW COLD FRONT PUSHES THRU. && .PREV DISCUSSION... /ISSUED 506 PM CDT WED MAY 1 2013/ UPDATE... FOR SEVERE THUNDERSTORM WATCH 146. DISCUSSION... A SEVERE THUNDERSTORM WATCH IS IN EFFECT FOR THE HILL COUNTRY AND SOUTHERN EDWARDS PLATEAU UNTIL MIDNIGHT TONIGHT. SHOWERS AND THUNDERSTORMS HAVE BEGUN TO DEVELOP ACROSS CENTRAL/WEST CENTRAL TEXAS AHEAD OF AN APPROACHING COLD FRONT. CURRENT SURFACE TEMPERATURES ACROSS THE CONCHO VALLEY AND WEST CENTRAL TEXAS HAVE REACHED INTO THE LOWER TO MID 90S. THE COMBINATION OF THE COLD FRONT...DRYLINE...AND WARM SURFACE TEMPERATURES COULD ENABLE SOME OF THE THUNDERSTORMS TO REACH SEVERE LEVELS THIS EVENING AND TONIGHT ACROSS THE HILL COUNTRY AND SOUTHERN EDWARDS PLATEAU. LARGE HAIL AND DAMAGING WINDS ARE THE PRIMARY THREATS. PREV DISCUSSION... /ISSUED 330 PM CDT WED MAY 1 2013/ SHORT TERM (TONIGHT THROUGH THURSDAY NIGHT)... SHORT TERM CONCERNS WILL BE CENTERED ON CONVECTION CHANCES ACROSS SOUTH CENTRAL TEXAS FROM THIS EVENING INTO EARLY TOMORROW MORNING. A DRYLINE CURRENTLY OVER WEST CENTRAL TEXAS FROM SOA TO NEAR ABI WILL APPROACH FROM THE WEST WHILE A STRONG COLD FRONT APPROACHES FROM THE NORTH. STORMS ARE EXPECTED TO INITIATE ACROSS THE BIG COUNTRY OF WEST CENTRAL TEXAS BY LATE THIS AFTERNOON...THEN DEVELOP ACROSS THE EDWARDS PLATEAU/HILL COUNTRY BY MID-EVENING. A SIGNIFICANT SOURCE OF LIFT IS LACKING...BUT IF STORMS MANAGE TO DEVELOP...WE COULD SEE SOME ISOLATED SEVERE THUNDERSTORMS...PRIMARILY NORTH OF HIGHWAY 90 AND WEST OF I-35. TIMING OF ANY SEVERE STORMS WILL BE FAVORED BETWEEN 9 PM AND 5 AM. LARGE HAIL AND DAMAGING WINDS WILL BE THE PRIMARY CONCERNS WITH ANY SEVERE THUNDERSTORMS THAT MANAGE TO DEVELOP. THE STRONG COLD FRONT WILL MOVE QUICKLY THROUGH THE AREA LATE TONIGHT AND THURSDAY MORNING. THERE WILL BE SOME IMPRESSIVE SURFACE PRESSURE RISES BEHIND THE BOUNDARY AND NORTH WINDS WILL BE ON THE INCREASE THROUGHOUT MOST OF THE DAY ON THURSDAY. WIND SPEEDS SHOULD REACH ADVISORY LEVELS (SUSTAINED 26-39 MPH) AND WE WILL ISSUE A WIND ADVISORY FOR ALL OF SOUTH CENTRAL TEXAS FROM 7AM-10PM. LONG TERM (FRIDAY THROUGH WEDNESDAY)... MUCH COOLER AIR WILL FILTER IN BEHIND THE FRONT THURSDAY NIGHT THROUGH FRIDAY PROVIDING PLENTY OF COLD AIR ADVECTION AND BREEZY NORTH WINDS. SURFACE WINDS FINALLY DECREASE FRIDAY NIGHT INTO SATURDAY MORNING. LIGHT WINDS...DRY AIR AND MOSTLY CLEAR SKIES MAY LEAD TO RECORD LOW TEMPERATURES BOTH FRIDAY NIGHT AND SATURDAY NIGHT. TEMPERATURES BEGIN TO REBOUND CLOSER TO CLIMATOLOGICAL NORMALS BY EARLY NEXT WEEK AS SOUTHEASTERLY WINDS SLOWLY STRENGTHEN. SOUTHWEST TO WESTERLY FLOW ALOFT REMAINS INTACT DURING THE EARLY AND MIDDLE PORTION OF THE UPCOMING WORK WEEK. THE DRYLINE MAY BECOME ACTIVE LATE IN THE FORECAST PERIOD...BUT CONFIDENCE IS TOO LOW TO MENTION ANY PRECIPITATION CHANCES AT THIS TIME. FIRE WEATHER... MOIST CONDITIONS CONTINUE THIS EVENING BEFORE A STRONG COLD FRONT MOVES THROUGH TONIGHT AND THURSDAY MORNING...BRINGING AN ABRUPT NORTHERLY WIND SHIFT AND DRIER AIR TO ALL OF SOUTH CENTRAL TEXAS. GUSTY NORTH WINDS AND MUCH COOLER TEMPERATURES ARE EXPECTED BEHIND THE COLD FRONT ON THURSDAY... HOWEVER WITH PLENTY OF COOL AIR...LIGHT PRECIPITATION AND CLOUD COVER... MINIMUM RH/S WILL ONLY DROP INTO THE 30-50% RANGE. ON FRIDAY...DRY AIR CONTINUES TO MOVE INTO THE REGION AND WITH TEMPERATURES WARMING A FEW DEGREES...MINIMUM HUMIDITIES WILL FALL TO NEAR 15% ALONG THE RIO GRANDE TO NEAR 25% EAST OF I-35. WINDS WILL BE NEAR 10 MPH ALONG THE RIO GRANDE TO NEAR 20 MPH ALONG AND EAST OF INTERSTATE 35. THIS WILL BRING A PERIOD OF NEAR CRITICAL FIRE WEATHER CONDITIONS TO SOUTH CENTRAL TEXAS FRIDAY AFTERNOON. WE STILL EXPECT THE WINDS WILL BE ON A DECREASING TREND DURING THE AFTERNOON WHILE HUMIDITIES ARE AT THEIR LOWEST. IN ADDITION... RECENT RAINFALL HAS HELPED TO KEEP FINE FUEL MOISTURE UP. CLIMATE...
