The radar
The Shreveport radar (KSHV), 172 km from the middle of the area, began a volume at 00:51 UTC, the scan nearest the moment this went out.
Open the radar archive at this moment
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
Shreveport, LA (KBAD), launched 00:00Z, 0.8 hours before the alert went out and 181 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 HOUSTON/GALVESTON TX 723 PM CDT THU JUL 3 2014 .DISCUSSION... SEE 00Z AVIATION DISCUSSION. && .AVIATION... SCATTERED SHRA/TSRA ACTIVITY CONTINUES ACROSS THE NORTHERN AND WESTERN PORTIONS OF THE FORECAST AREA. THIS ACTIVITY WILL DECREASE IN INTENSITY OVER THE NEXT FEW HOURS. AT THIS TIME...CLL IS THE ONLY TERMINAL THAT STILL HAS LIGHTNING IN THE VICINITY. VFR CONDITIONS WILL PREVAIL OVER NIGHT EXCEPT AT RURAL TERMINALS WHERE PATCHY MVFR CONDITIONS ARE POSSIBLE BEFORE DAYBREAK. THE MVFR CIGS AND VSBY SHOULD QUICKLY LIFT AFTER SUNRISE. WITH A STATIONARY FRONTAL BOUNDARY STALLED OUT OVER THE AREA ON FRIDAY...WOULD EXPECT ANOTHER ROUND OF SCATTERED SHOWERS AND THUNDERSTORMS. WHILE ISOLATED SHOWERS ARE POSSIBLE BETWEEN 16 TO 18Z...THE HEAVIEST THUNDERSTORM ACTIVITY IS LIKELY TO EFFECT THE INLAND TERMINALS BETWEEN 20 AND 23Z. 44 && .PREV DISCUSSION ISSUED AT 353 PM CDT... LATEST RADAR COMPOSITE SHOWING THUNDERSTORMS AS EXPECTED MAINLY OVER NORTHEAST HALF OF FORECAST AREA. STORMS CONTINUALLY ARE PRODUCING OUTFLOWS WHICH ARE GENERATING NEW STORMS...LEADING TO THE RING APPEARANCE ON RADAR. EXPECT THIS ACTIVITY TO CONTINUE TO SAG SOUTHEASTWARD AND IMPACT THE GREATER HOUSTON AREA OVER THE NEXT FEW HOURS. AIR MASS SOMEWHAT MORE STABLE OVER FAR SW COUNTIES SO WOULD EXPECT THINGS TO DIMIMISH AS THE BOUNDARY GETS THERE...AND WITH THE LOSS OF DAYTIME HEATING. LIGHTNING AND HEAVY DOWNPOURS ARE THE MAIN THREATS...ALTHOUGH GUSTS TO NEAR 40 MPH WERE REPORTED WITH SOME OF THE OUTFLOWS. ALSO HAVE HAD PEA SIZED HAIL IN A FEW STORMS...AND SOME HAIL IS POSSIBLE WITH STRONGER CELLS ALTHOUGH SHOULD BE MAINLY SMALL WITH THESE PULSE STORMS. CANT RULE OUT A SEVERE REPORT OR TWO. THE FOURTH OF JULY LOOKS TO BE SIMILAR TO TODAY...WITH SIMILAR AIR MASS AND SET UP...AND SHOWERS AND THUNDERSTORMS LIKELY FORMING BY EARLY AFTERNOON. WHERE THEY FORM WILL BE HARD TO TELL...BUT TODAYS CONVECTION WILL LIKELY LAY DOWN BOUNDARIES THAT COULD LINGER INTO TOMORROW...AND WIND SHIFT BOUNDARY TO NORTHEAST...AND SEA BREEZE ALONG COAST ALL GOOD CANDIDATES. THIS ACTIVITY COULD IMPACT ACTIVITIES AND ALL NEED TO BE AWARE OF THE LIGHTNING THREAT AND READY TO TAKE SHELTER INDOORS OR IN A VEHICLE SHOULD SITUATION WARRANT.
