Local storm reports filed while the alert was in force, from inside its polygon or its counties.
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
Santa Teresa, NM (KEPZ), launched 12:00Z, 8.2 hours before the alert went out and 220 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.

$$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 Midland/Odessa, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 20, 2:14 PM CDT, 57 minutes earlier.
Area forecast discussion, Aug 20, 2:14 PM CDT, 57 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX 214 PM CDT MON AUG 20 2007 .SHORT TERM... A COUPLE OF SHORTWAVE TROUGHS...ONE OVER THE LOWER TRANS PECOS AND THE OTHER OVER EASTERN NEW MEXICO...WILL CONTINUE TO TRANSLATE SOUTH AND SOUTHWESTWARD AROUND THE EASTERN FRINGE OF AN UPPER LEVEL RIDGE CENTERED OVER EASTERN ARIZONA AND WESTERN NEW MEXICO THIS AFTERNOON. EXPECT THESE WAVES TO SPARK THUNDERSTORM DEVELOPMENT THIS AFTERNOON AND EVENING ALONG A SURFACE TROUGH THAT EXTENDED FROM EASTERN NEW MEXICO...SOUTH TO THE BIG BEND REGION. MID LEVEL LAPSE RATES OVER 7 C/KM WILL AID THIS DEVELOPMENT...WHILE AMPLE MOISTURE AND DAYTIME HEATING THESE AREAS WILL RESULT IN CAPES OF LEAST 2000 J/KG. SINCE 0 TO 6 KM BULK SHEAR VECTORS WILL BE AT LEAST 30 KT...AND UP TO 40 KT...EXPECT SOME OF THE STORMS TO BE SEVERE WITH LARGE HAIL AND DAMAGING WINDS THE MAIN THREATS. HEAVY RAIN AND LOCALIZED FLASH FLOODING WILL ALSO BE POSSIBLE. EXPECT STORMS TO DEVELOP/LAST INTO THE EVENING...ESPECIALLY OVER SOUTHEASTERN NEW MEXICO WHERE A 40 KT H85 JET COULD INSTIGATE/PROPAGATE DEVELOPMENT. STORMS SHOULD MOVE OFF TO THE SOUTHWEST IN FLOW AROUND THE UPPER RIDGE/S PERIPHERY AND GRADUALLY DECREASE IN COVERAGE AND INTENSITY THIS EVENING. ADJUSTED MINIMUM TEMPERATURES UPWARD A LITTLE CONSIDERING CLOUD COVER AND SURFACE WINDS REMAINING AT LEAST IN THE 5 TO 10 MPH RANGE OVERNIGHT. .LONG TERM... THE MAIN FOCUS FOR THE LONG TERM WILL CONTINUE TO BE THE TUTT LOW AND HURRICANE DEAN. THE TUTT LOW IS PROGGED TO BE OVER THE LOWER VALLEY BY 12Z TUESDAY AS HURRICANE DEAN CROSSES THE YUCATAN PENINSULA. THE TUTT LOW IS EXPECTED TO OPEN INTO AN INVERTED TROUGH AS IT APPROACHES THE BIG BEND REGION BY 12Z WEDNESDAY. MODELS ARE NOT PROGGING MUCH PRECIPITATION WITH THIS SYSTEM... HOWEVER WILL CONTINUE TO CARRY LOW POPS OVER THE SOUTHERN CWA INCLUDING THE HIGHER ELEVATIONS. HURRICANE DEAN IS PROGGED BY THE GFS TO MOVE IN A WESTERLY DIRECTION ACROSS NORTHERN MEXICO REMAINING TO FAR SOUTH TO HAVE MUCH EFFECT ON THE CWA. THE NAM MOVES DEAN FARTHER NORTH WHICH WOULD PRODUCE PRECIPITATION OVER THE SOUTHERN CWA. WILL STAY CLOSER TO THE GFS AS IT IS IN BETTER AGREEMENT WITH THE EUROPEAN AND THE UKMET MODELS. WILL CONTINUE TO CARRY LOW POPS IN THE FORECAST ESPECIALLY FOR THE SOUTHERN AND WESTERN CWA FOR ANY CHANGE IN DEANS PATH AND FOR MOISTURE THAT WILL STREAM OVER THE AREA FROM THE STORM. MOST OF THE MOISTURE IS EXPECTED STREAM OVER THE WESTERN CWA AROUND THE WESTERN FRINGE OF AN UPPER HIGH THAT IS PROGGED TO BUILD INTO THE AREA FROM THE EAST. HIGH TEMPERATURES WILL BE AT OR BELOW NORMAL THROUGH MOST OF THE LONG TERM DUE TO CLOUD COVER AND THE MIGRATION OF THE THERMAL RIDGE TO THE WEST. HIGHS WILL RANGE FROM THE UPPER 80S AND LOW 90S NORTHEAST TO THE MID AND UPPER 90S IN THE SOUTH. LOWS WILL RANGE IN THE UPPER 60S TO LOWER 70S MOST AREAS AS WINDS AND CLOUD COVER INHIBIT RADIATIONAL COOLING. A WEAK COLD FRONT IS PROGGED TO APPROACH THE CWA FROM THE NORTH EARLY NEXT WEEK. GFS TRIES TO BREAK OUT PRECIPITATION WITH THIS FRONT. THIS PRECIPITATION COULD EFFECT THE NORTHERN CWA IF THE FRONT MOVES FAR ENOUGH TO THE SOUTH. && .PRELIMINARY POINT TEMPS/POPS...
