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 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
Del Rio, TX (KDLF), launched 00:00Z, 2.0 hours before the alert went out and 113 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.

LESS COVERAGE OF SHRA/TSRA ON SAT WITH NO MENTION IN TAFS. PREV DISCUSSION... /ISSUED 324 PM CDT FRI AUG 29 2014/ SHORT TERM (TONIGHT THROUGH SATURDAY NIGHT)... UPPER AIR ANALYSIS THIS MORNING SHOWED A DEEP TROUGH EXTENDING FROM THE NORTHERN PLAINS TO TEXAS WITH AN EASTERLY WAVE IN THE GULF OFF THE TEXAS COAST. THE TROPICAL SYSTEM HAS A SURFACE REFLECTION OVER THE GULF CENTERED EAST OF BROWNSVILLE. HIGH PRESSURE TO THE NORTHEAST HAS WINDS ACROSS SOUTH CENTRAL TEXAS FROM THE EAST TO SOUTHEAST. THERE HAS BEEN LITTLE CHANGE TO THE MOISTURE FROM 24 HOURS AGO. THE NORTHERN STREAM TROUGH WILL GRADUALLY LIFT TO THE NORTHEAST DURING THIS PERIOD WHILE THE TROPICAL SYSTEM DISSIPATES. THIS WILL LEAD TO CONTINUING CHANCES FOR SHOWERS AND THUNDERSTORMS ESPECIALLY ACROSS THE EASTERN HALF OF THE CWA. MARGINAL CAPE VALUES SUGGEST ANY THUNDERSTORMS COULD BE STRONG WITH GUSTY WINDS THE MAIN THREAT. MODELS ARE BACKING OFF HIGH PW SO ANY HEAVY RAIN WILL LIKELY BE LIMITED TO THE COASTAL PLAINS. LONG TERM (SUNDAY THROUGH FRIDAY)... AS THE SUBTROPICAL RIDGE RE-ESTABLISHES ITSELF ACROSS SOUTH TEXAS...THE LOW LEVEL FLOW WILL REMAIN FROM THE SOUTHEAST. THIS WILL MEAN SLIGHT RAIN CHANCES WILL LINGER OVER THE SOUTHEAST INTO THE EARLY PART OF NEXT WEEK. MODELS ARE HINTING AT ANOTHER EASTERLY WAVE MOVING ACROSS THE GULF FOR THE MIDDLE OF NEXT WEEK. THIS WILL KEEP SLIGHT CHANCE POPS IN THE FORECAST ACROSS OUR SOUTHERN AREA EACH DAY WEDNESDAY THROUGH FRIDAY. && .PRELIMINARY POINT TEMPS/POPS...
