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

Lake Charles Mun, LA (KLCH), launched 12:00Z, 5.2 hours before the alert went out and 72 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.

AVIATION UPDATE...REGARDING 12Z TAF ISSUANCE. A NORTH TO SOUTH
ORIENTED FRONT IS EXPECTED TO REMAIN OVER EAST TEXAS THROUGH
TODAY. THIS COMBINED WITH STRENGTHENING SHORTWAVE ENERGY
COMING IN FROM THE WEST WITH BRING A GOOD CHANCE FOR SHOWERS AND
POSSIBLY A FEW THUNDERSTORMS AT ALL TERMINALS TODAY.

MARCOTTE

PREV DISCUSSION... /ISSUED 444 AM CDT MON SEP 30 2013/

DISCUSSION...
TEMPERATURES RANGE FROM THE 40S TO 50S AS FAR SOUTH AS OKLAHOMA
THIS MORNING. TEMPERATURES ACROSS EASTERN TEXAS AND LOUISIANA
REMAIN IN THE UPPER 60S TO LOWER 70S AHEAD OF A STALLED FRONT.
THIS FRONT IS PRODUCING SHOWERS ACROSS SOUTHERN LOUISIANA AND
SOUTHEAST TEXAS WITH STRONGER STORMS NOTED IN THE GULF SOUTH OF
JEFFERSON COUNTY. STORMS ARE MOVING TO THE NORTHEAST. CLOUDS AND
RAINS TODAY WILL HOLD TEMPERATURES IN THE 80S. RAINS WILL
GENERALLY PRODUCE AROUND 1/2 INCH OF RAINFALL WITH SOME LOCATIONS
GETTING A BIT MORE.

THE STALLED FRONT WILL BE THE FOCUS FOR SHOWERS AND THUNDERSTORMS
OVER THE NEXT SEVERAL DAYS AS A SERIES OF SHORTWAVES RIPPLE
ACROSS THE REGION. THE FRONT WILL LOOSE IT'S IDENTITY BY LATE
TUESDAY WITH STORMS TAPERING OFF A BIT OFF ON WEDNESDAY INTO
THURSDAY. THIS WILL ALLOW TEMPERATURES TO CREEP BACK INTO THE
LOWER 90S IN SOME LOCATIONS. BUT THIS WILL BE SHORT LIVED AS THE
FIRST TRUE COLD FRONT OF THE SEASON LOOKS TO MOVE THROUGH ON
SATURDAY. SHOWERS AND THUNDERSTORMS ARE EXPECTED AHEAD OF THE
FRONT ENDING WITH THE WIND SHIFT. LOW TEMPERATURES ACROSS THE
LAKES REGION IN SOUTHEAST TEXAS AND CENTRAL LOUISIANA ARE EXPECTED

OVER THE SOUTHWESTERN CARIBBEAN SEA A BROAD AREA OF LOW PRESSURE
IS PRODUCING WIDESPREAD CLOUDINESS WITH SOME DISORGANIZED SHOWERS
THIS MORNING. OTHERWISE THE TROPIC'S REMAIN QUIET.
