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, 11.4 hours before the alert went out and 26 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 9, 3:25 PM MDT, 2 hours 1 minute before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EL PASO TX/SANTA TERESA NM
325 PM MDT THU AUG 9 2007

.SYNOPSIS...
ENOUGH MOISTURE WILL GIVE US ANOTHER ROUND OF AFTERNOON AND
EVENING THUNDERSTORMS ON FRIDAY. FOR THE WEEKEND AND BEYOND HIGH
PRESSURE WILL DRY US OUT AND GIVE US ONLY A SLIGHT CHANCE FOR
THUNDERSTORMS EACH DAY. TEMPERATURES WILL RUN A LITTLE ABOVE
NORMAL THROUGH THE START OF NEXT WEEK.

&&

.DISCUSSION...
WILL KEEP THIS SHORT AS WE ARE WORKING SEVERE WEATHER RIGHT NOW.
MOISTURE PLUME HAS HELPED KICK OFF SEVERE STORMS OVER THE EASTERN
PART OF THE CWA THIS AFTERNOON. STORMS SHOULD BEGIN TO SLOW DOWN
LATER THIS EVENING. STORMS WILL AGAIN BE POSSIBLE ON FRIDAY
ESPECIALLY OUT WEST. HIGH PRESSURE ALOFT WILL BEGIN TO BUILD INTO
OKLAHOMA AND THAT WILL SCOUR OUT A LOT OF MOISTURE. SO WE WILL
DROP BACK ON THE POPS INTO THE SLIGHT CHANCE CATEGORY. IF MODEL
TRENDS CONTINUE WE MAY HAVE TO PULL THE POPS FOR THE FIRST PART OF
NEXT WEEK. FOR NOW WE WILL KEEP THEM IN AND WAIT FOR ONE MORE
MODEL RUN. WITH HIGH PRESSURE BUILDING IN WE CAN EXPECT OUR
AFTERNOON HIGHS TO RUN A LITTLE ABOVE NORMAL FOR THE WEEKEND INTO
THE FIRST PART OF NEXT WEEK.
