What was reported inside it

Time	Report	Where	Remark
May 25, 6:03 PM CDT	HEAVY RAIN 2.75	Kimberling City, MO

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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 12:00Z, 8.5 hours before the alert went out and 58 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.

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.

Area forecast discussion, May 25, 3:20 PM CDT, 10 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
320 PM CDT TUE MAY 25 2010

.DISCUSSION...

PULSE TYPE THUNDERSTORMS DEVELOPED ACROSS THE MISSOURI OZARKS
TUESDAY WITHIN AN AXIS OF DEEP MOISTURE CONVERGENCE ALONG A NORTH
TO SOUTH SURFACE BOUNDARY FROM NORTHEAST TO SOUTHWEST MISSOURI.
STORMS CONTINUED TO DEVELOPED THROUGH THE AFTERNOON ALONG
PROPAGATING OUTFLOW BOUNDARIES. MIXED LAYER CAPE WAS NEAR 2000
J/KG BUT THERE WAS VERY LITTLE IF ANY SHEAR. ENVIRONMENT WILL BE
FAVORABLE FOR THE CONTINUED DEVELOPMENT OF PULSE TYPE
THUNDERSTORMS THROUGH THE LATE AFTERNOON AND EARLY EVENING HOURS
WHERE OUTFLOW BOUNDARIES INTERACT WITH THE UNSTABLE AIRMASS. THERE IS A
LIMITED RISK FOR SEVERE STORMS WITH LOCALIZED DAMAGING WINDS AND
HAIL. LOCALIZED FLOODING CANNOT BE RULED OUT GIVEN THE SLOW
MOVEMENT OF THE STORMS AND PRECIPITABLE WATER VALUES NEAR 1.5
INCHES.

THE CONVECTION WILL DIMINISH OVERNIGHT WITH THE LOSS OF DAY TIME
HEATING. GIVEN THE MOIST CONDITIONS AND POCKETS OF SIGNIFICANT
RAINFALL THAT OCCURRED TODAY...PATCHY FOG WILL BE POSSIBLE ACROSS
THE AREA EARLY WEDNESDAY MORNING.

AN UPPER RIDGE OF HIGH PRESSURE WILL REMAIN THE DOMINANT WEATHER
FEATURE THE NEXT FEW DAYS. UNDERNEATH THE HIGH A WEAK SURFACE
FRONT WILL SAG SOUTHEAST INTO THE REGION WEDNESDAY. THE MASS
CONVERGENCE ALONG THIS BOUNDARY ALONG WITHIN AN ENVIRONMENT
SIMILAR AS TODAY WILL SUPPORT SCATTERED TO NUMEROUS CONVECTION
WEDNESDAY AFTERNOON. STRONG TO ISOLATED SEVERE PULSE TYPE STORMS
WILL BE POSSIBLE. THE CHANCE OF PRIMARILY DIURNALLY DRIVEN
CONVECTION WILL DEVELOP AGAIN THURSDAY AS THE BOUNDARY SETTLES
SOUTH ACROSS SOUTHERN MISSOURI.

SURFACE HIGH PRESSURE WILL BUILD INTO THE REGION FROM THE GREAT
LAKES TO END THE WEEK ALLOWING DRIER AIR TO ADVECT INTO THE
REGION. EXPECT MOSTLY DRY CONDITIONS FRIDAY INTO SATURDAY. THE
CHANCE OF PRECIPITATION MAY RETURN AS EARLY SUNDAY AND CONTINUE
INTO MEMORIAL DAY AS THE UPPER RIDGE FLATTENS AND A FRONT ATTEMPTS
TO PUSH SOUTH INTO THE REGION.

FOSTER

&&

.AVIATION...

FOR THE 1800Z TAFS...BOTH UPPER LEVEL AND SURFACE RIDGES OF HIGH
PRESSURE OVER THE GREAT LAKES ARCHING SOUTHWARD TO THE CENTRAL
GULF COAST WHICH DOMINATED THE OZARKS AND SOUTHEASTERN KANSAS OVER
THE PAST DAY OR SO ARE GRADUALLY WEAKENING. WEAKENING OF THIS
RIDGE...A WARM MOIST AIRMASS IN PLACE AND A FRONTAL SYSTEM SLOWLY
APPROACHING FROM THE WEST WILL ALLOW CONVECTION TO CONTINUE TO
DEVELOP TODAY AND TOMORROW AFTERNOON. ABUNDANT LOW LEVEL MOISTURE
AND LIGHT WINDS WILL ALLOW GROUND FOG AND HAZE TO DEVELOP DURING
THE EARLY MORNING HOURS...ESPECIALLY IN LOW LYING AREAS. FORECAST
SOUNDINGS DEPICT A SIMILAR ENVIRONMENT FOR WEDNESDAY AFTERNOON
WITH SCATTERED SHOWERS AND THUNDERSTORMS AGAIN POSSIBLE.
