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

Springfield, MO (KSGF), launched 00:00Z, 8.4 hours before the alert went out and 234 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.

What forecasters said that day

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Springfield, MO wrote its last area forecast discussion before this flash flood warning went out at Jul 13, 2:27 AM CDT, 57 minutes earlier.

Area forecast discussion, Jul 13, 2:27 AM CDT, 57 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
227 AM CDT WED JUL 13 2011

.DISCUSSION...

MAIN FOCUS WILL BE WITH RAIN CHANCES/AMOUNTS AS THIS UPPER LEVEL
TROPICAL DISTURBANCE SLOWLY PUSHES ACROSS THE AREA TODAY INTO THURSDAY.

MOISTURE HAS INCREASED SINCE THE 00Z SGF SOUNDING WHICH HAD 1.65
PW VALUES AND NOW ESTIMATED AROUND 1.8 TO 1.9 IN. SEEING DECENT
RAINFALL RATES WITH THE CONVECTION TONIGHT WHICH IS OUT AHEAD OF
THE MAIN SHORTWAVE STILL NEAR ICT. HAVE HAD SOME REPORTS OF
FLOODING OVER A PORTION OF CENTRAL MISSOURI WHICH IS REALLY THE
ONLY AREA WHICH HAD A DECENT RAIN TOTAL DURING THE MONTH OF JUNE.

SHORTWAVE WILL BE VERY SLOW TO MOVE EASTWARD AS IT CUTS THROUGH
THE UPPER RIDGE OVER EASTERN KANSAS AND THE MISSOURI OZARKS. WITH
TROPICAL LIKE MOISTURE IN PLACE...WILL LIKELY CONTINUE TO SEE
CONVECTION THROUGH THURSDAY OVER THE CWA. MODELS HAVING A
DIFFICULT TIME WITH THIS SYSTEM AND ARE OFFERING A WIDE VARIETY OF
SOLUTIONS. PAST COUPLE OF NIGHTS THIS SYSTEM HAS DEVELOPED SHOWERS
AND THUNDERSTORMS WITH VERY SLOW MOVING STORMS IN THE VICINITY OF
THE UPPER WAVE AND SEE NO REASON THAT THIS TREND WILL NOT CONTINUE
INTO TONIGHT OVER OUR CWA. SO HAVE GONE WITH HIGHER PRECIPITATION
CHANCES THAN WHAT GUIDANCE OR PREVIOUS FORECASTS HAVE HAD.

THE RAIN/CLOUDS WILL ALSO ACT TO KEEP TEMPERATURES COOLER THAN
THEY HAVE BEEN OVER THE PAST SEVERAL DAYS AND NOT EXPECTING ANY
HEAT RELATED PRODUCTS...AT LEAST THROUGH THURSDAY.

BY FRIDAY...UPPER LEVEL SYSTEM SHOULD SHIFT SOUTH AND EAST OF THE
AREA WITH THE RIDGE BUILDING BACK INTO THE REGION. SHOULD START TO
SEE TEMPERATURES RISE BACK INTO THE MID TO UPPER 90S OVER THE
WESTERN CWA BY THEN WITH THE WARMER TEMPERATURES CREEPING EASTWARD
INTO THE CWA OVER THE WEEKEND. WARMEST 850 TEMPERATURES SHOULD
REMAIN WEST OF THE AREA HEADING INTO THE WEEKEND SO NOT EXPECTING
AS HOT OF TEMPERATURES AS WE HAVE SEEN IN THE PAST FEW DAYS.

1229 AM CDT WED JUL 13 2011

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF THE MISSOURI
OZARKS AND EXTREME SOUTHEAST KANSAS.

.DAY ONE...TONIGHT.

THE HAZARDOUS WEATHER RISK LEVEL IS...SIGNIFICANT.

WEATHER HAZARDS EXPECTED...

SIGNIFICANT LIGHTNING RISK.
LIMITED THUNDERSTORM WIND RISK.
LIMITED HAIL RISK.
LIMITED FLASH FLOODING RISK.

DISCUSSION...

THUNDERSTORMS WILL BECOME MORE NUMEROUS OVERNIGHT ACROSS THE
MISSOURI OZARKS AND SOUTHEAST KANSAS WITH FREQUENT CLOUD TO GROUND
LIGHTNING POSSIBLE. WHILE MOST OF THE STORMS SHOULD REMAIN BELOW
SEVERE LIMITS WITH WIND GUSTS BELOW 50 MPH...SOME OF THE STRONGER
STORMS MAY PRODUCE WIND GUSTS OVER 60 MPH AND HAIL TO THE SIZE OF
QUARTERS. HEAVY RAINFALL WILL ALSO ACCOMPANY THE STORMS AND MAY
LEAD TO ISOLATED FLASH FLOODING IF STORMS MOVE ACROSS THE SAME LOCATIONS.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.

THE CHANCE FOR THUNDERSTORMS WILL CONTINUE WEDNESDAY AND THURSDAY
AS THE UPPER LEVEL DISTURBANCE MOVES ACROSS THE AREA. A FEW
STRONG TO SEVERE STORMS WILL BE POSSIBLE.

THUNDERSTORMS THAT DEVELOP WEDNESDAY AND THURSDAY WILL BE CAPABLE
OF PRODUCING PERIODS OF LOCALIZED VERY HEAVY RAINFALL. LOW SOIL
MOISTURE DUE TO BELOW NORMAL RAINFALL OVER THE LAST ONE TO TWO
MONTHS WILL MITIGATE SOME OF THE FLOODING RISK...BUT A FEW
INSTANCES OF LOCALIZED FLOODING IN POOR DRAINAGE AREAS WILL BE
POSSIBLE.

HOT WEATHER WILL RETURN LATE IN THE WEEK INTO NEXT WEEKEND...WITH
HEAT INDEX VALUES OVER 100 DEGREES LIKELY.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED THROUGH TONIGHT.
