The Midland/Odessa radar (KMAF), 72 km from the middle of the area, began a volume at 08:49 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

Midland Regional, TX (KMAF), launched 00:00Z, 8.8 hours before the alert went out and 73 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, Aug 25, 3:28 AM CDT, 18 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
328 AM CDT WED AUG 25 2010

.DISCUSSION...
ON WATER VAPOR IMAGERY THE REMNANTS OF A SHORTWAVE TROUGH CAN BE
SEEN PROVIDING INSTABILITY TO WEST TEXAS AND SOUTHEASTERN NEW
MEXICO. THE RECENT PASSAGE OF A STRONG COLD FRONT THROUGH THE CWA
HAS PROVIDED MOISTURE TO THE AREA. THE UPPER TRANS PECOS AND
STOCKTON PLATEAU REGIONS HAVE SEEN COPIOUS AMOUNTS OF RAIN THROUGH
THE EVENING YESTERDAY. SEVERAL FLASH FLOOD WARNINGS WERE ISSUED FOR
THIS EVENT. ON RADAR HEAVY AMOUNTS OF RAIN CAN STILL BE SEEN FALLING
OVER THESE AREAS. SHOWERS AND THUNDERSTORMS CAN BE SEEN ELSEWHERE IN
THE PERMIAN BASIN AND SOUTHEASTERN NEW MEXICO MOSTLY BRINGING LIGHT
RAIN. WIND ACROSS THE REGION IS GENERALLY NORTH TO NORTHEASTERLY AT
10 TO 15 KNOTS SUSTAINED...WITH THE EXCEPTION OF THE GUADALUPE
MOUNTAINS WHICH HAS SUSTAINED WINDS OF AROUND 35 KNOTS.

THE HIGH PRESSURE THAT HAS BEGUN TO BUILD IN OVER THE FOUR CORNERS
REGION WILL CONTINUE TO BUILD THROUGHOUT TODAY. THIS WILL KEEP A
NORTHEAST FLOW ALOFT FOR THE NEXT COUPLE OF DAYS. AT THE SURFACE
HIGH PRESSURE RIDGING WILL BEGIN TO BUILD IN. THE FLOW WILL CONTINUE
TO COME FROM THE NORTHEAST THROUGHOUT TODAY. TEMPERATURES WILL BE
COOLER THAN NORMAL TODAY. FRIDAY WE'LL SEE A MORE EASTERLY FLOW AT
THE SURFACE KEEPING MOISTURE FLOWING INTO THE AREA. ISOLATED
THUNDERSTORMS MAY OCCUR IN THE MOUNTAINS THROUGH FRIDAY.
TEMPERATURES FOR TODAY WILL BE COOLER THAN NORMAL...THEN BEGIN TO
GRADUALLY WARM BACK UP TO NORMAL.

BY FRIDAY EVENING THE UPPER LEVEL HIGH WILL BEGIN TO MOVE EAST AND
BY SATURDAY WILL BE SITUATED OVER THE APPALACHIAN MOUNTAINS. THIS
WILL RESULT IN A WEAK SOUTHWEST FLOW ALOFT OVER THE AREA. AT THE
SURFACE THE FLOW WILL TAKE ON A SOUTHEASTERLY DIRECTION. ISOLATED
THUNDERSTORMS MAY OCCUR THESE DAYS AS WELL FOR THE MOUNTAINOUS
AREAS. BY SUNDAY THE NEXT SHORTWAVE WILL BEGIN TO MAKE ITS WAY OVER
THE WEST COAST. INCREASED CHANCES OF PRECIPITATION WILL OCCUR FOR
EARLY NEXT WEEK AS THIS FEATURE MAKES ITS WAY INTO THE CENTRAL
UNITED STATES.
