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

Midland Regional, TX (KMAF), launched 12:00Z, 8.4 hours before the alert went out and 141 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
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
152 PM CDT FRI AUG 22 2003

.SHORT TERM...
22/12Z UPPER AIR ANALYSES INDICATED A 250MB SHEAR AXIS STRETCHED
FROM THE BIG BEND REGION NORTHEAST INTO WESTERN OK. IN
ADDITION...PLENTY OF LOW-LEVEL MOISTURE WAS AROUND THE AREA WITH
850MB DEW POINTS OF 18C AT KDRT. THE LATEST WV SATELLITE REVEALS A
WEAK UPPER LOW ALONG THE CENTRAL PORTION OF THE TEXAS GULF COAST.
WILL ALSO COMMENT THAT 12Z MODELS DID NOT CAPTURE THE COOLER AIR AT
500MB (-10C) OVER CENTRAL AND EAST TEXAS THIS MORNING. GIVEN THE
ABOVE FACTORS AND A SERIES OF EMBEDDED WAVES IN THE MID-LEVEL
EASTERLY FLOW...SCATTERED THUNDERSTORMS ARE EXPECTED IN THE SHORT
TERM FORECAST.  CURRENT GRIDS ARE IN LINE WITH THE LATEST MOS
GUIDANCE...SO ONLY MINIMAL CHANGES WERE MADE.

&&

.LONG TERM...
THE SUBTROPICAL RIDGE WILL REMAIN CENTERED ACROSS THE CENTRAL PLAINS
OVER THE NEXT FEW DAYS. WEAK SHORTWAVES WILL CONTINUE TO ROTATE
AROUND THE SOUTHERN SIDE OF THE RIDGE THROUGH THE WEEKEND. IN
ADDITION...A SHEAR AXIS WILL LIKELY SET UP SOMEWHERE ACROSS THE
SOUTHERN HALF OF THE CWA BOTH SATURDAY AND SUNDAY. WILL KEEP THE
HIGHEST POPS IN THE SOUTH ALONG THE EXPECTED POSITION OF THE SHEAR
AXIS. WILL ALSO MAINTAIN A SLIGHT CHANCE OF THUNDERSTORMS ACROSS THE
ENTIRE AREA MONDAY AND TUESDAY...AS ADDITIONAL SHORTWAVE ENERGY
CONTINUES TO TRANSLATE ACROSS THE CWA.

THE GFS ADVERTISES A STRONG COLD FRONT TO PUSH THROUGH THE AREA LATE
TUESDAY OR EARLY WEDNESDAY. DO NOT HAVE MUCH CONFIDENCE THAT A FRONT
OF THIS STRENGTH AND SPEED WILL AFFECT THE AREA AT THIS POINT.
HOWEVER...THE ECMWF DOES ADVERTISE A WEAKER FRONTAL PASSAGE BY
WEDNESDAY NIGHT OR THURSDAY MORNING. WILL NOT MAKE ANY DRASTIC
CHANGES TO THE EXTENDED PORTION OF THE FORECAST...AND WILL GENERALLY
KEEP WEDNESDAY THROUGH FRIDAY NEAR OR SLIGHTLY BELOW CLIMATOLOGIAL
LEVELS AND SEE WHAT LATER MODELS SHOW.
