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, 4.6 hours before the alert went out and 106 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, Jun 19, 5:59 PM CDT, 5 hours 38 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
559 PM CDT THU JUN 19 2008

...UPDATE TO AVIATION...

...MESOSCALE CONVECTIVE DISCUSSION...

.UPDATE...

A BRIEF LULL IN THE ACTION UNTIL ADDITIONAL TSRA DEVELOPMENT MOVES
IN FROM THE NORTHWEST.

CURRENTLY...SGF WSR-88D INDICATES THAT A LARGE OUTFLOW BOUNDARY
EXTENDS FROM NEAR JERICO SPRINGS SOUTHWARD TO FREISTATT TO SHELL
KNOB TO FAR SOUTHWESTERN STONE COUNTY. SCT TSRA CONTINUES TO FIRE
ON THE EASTERN SIDE OF THIS BOUNDARY DUE TO LINGERING LOW LEVEL
CONVERGENCE. ADDITIONAL TSRA ACTIVITY CONTINUES TO GARNER STRENGTH
JUST TO OUR NORTH AND NORTHWEST OVER E KS AND NW MO. EVEN MORE
TSRA GROWTH HAS BEEN OBSERVED DURING THE PAST FEW HOURS FARTHER TO
THE NORTH OVER NEB AND IA.

CONVECTION THAT AFFECTED THE HWY 65 CORRIDOR HAS DONE A NUMBER ON
THERMODYNAMIC PROFILES. TEMPERATURES HAVE COOLED TO AROUND
70F...AND BOTH SBCAPE AND MLCAPE VALUES HAVE PLUMMETED INTO THE
HUNDREDS OF J/KG. AREAS THAT WERE UNTOUCHED BY CONVECTION THIS
AFTERNOON REMAINED PRIMED FOR SUPPORTING CONTINUED TSRA
DEVELOPMENT. IN GENERAL...SBCAPE AND MLCAPE ARE NEAR 2000 J/KG.
WITH DEEP LAYER SHEAR NEARING 40KT...SUPERCELL STRUCTURES WILL
REMAIN POSSIBLE THIS EVENING. MID LEVEL WAVE WITHIN NW FLOW ALOFT
WILL CONTINUE TO PROVIDE FOCUS FOR LIFT AS IT MOVES INTO MO.

THE END RESULT IS THAT ANOTHER PERIOD OR TWO OF TSRA ARE IN THE
OFFING FOR THE AREA THROUGH TONIGHT. SEVERE RISK WILL BE MOST
PROMINENT THIS EVENING...SLACKENING OFF DUE TO DECREASED
INSTABILITY DURING THE OVERNIGHT HOURS...THOUGH THE RISK FOR
TORRENTIAL RAIN AND LOCALIZED FLASH FLOODING WILL REMAIN.

.DISCUSSION...

THUNDERSTORMS HAVE DEVELOPED ACROSS THE CENTRAL PORTION OF THE CWA
THIS AFTERNOON...ALONG A BOUNDARY ROUGHLY LOCATED ALONG THE
HIGHWAY 65 CORRIDOR. STRONG TO SEVERE STORMS HAVE DEVELOP AS ML
CAPE OF 1200 TO 2000 J/KG AND 0-6KM BULK SHEAR AROUND 30KT IS
LOCATED ACROSS THE AREA. WITH THE INSTABILITY...SHEAR AND STEEP
LAPSE RATES LARGE HAIL WILL BE POSSIBLE WITH THESE STORMS. THE
TORNADO THREAT LOOKS TO BE LIMITED DUE TO THE LACK OF LOW LEVEL
SHEAR...HOWEVER WITH THE DEEP LAYER SHEAR SUPERCELLS ARE POSSIBLE...SO
CANNOT RULE OUT AN ISOLATED TORNADO.

IN ADDITION TO THIS ACTIVITY...AN UPPER LEVEL SHORTWAVE IS MOVE
ACROSS THE CENTRAL PLAINS. THIS SHORTWAVE IS THE FOCUS FOR
THUNDERSTORM DEVELOPMENT FROM NORTH CENTRAL OKLAHOMA INTO IOWA.
THIS SHORTWAVE WILL CONTINUE TO PUSH TOWARDS THE AREA THIS
AFTERNOON AND EVENING. AS A RESULT THE THUNDERSTORMS ACROSS
KANSAS AND NEBRASKA WILL PUSH INTO THE AREA THIS EVENING. WIND
SHEAR AND INSTABILITY WILL REMAIN SIGNIFICANT ENOUGH TO SUPPORT
SEVERE THUNDERSTORMS THIS EVENING. THE MAIN HAZARDS WITH THESE
STORM WILL BE LARGE HAIL AND DAMAGING WINDS. ALSO...THESE STORMS
WILL BE CAPABLE OF PRODUCING VERY HEAVY RAINFALL AND LOCALIZED
FLASH FLOODING. THUNDERSTORM CHANCES WILL LINGER ACROSS THE AREA
THROUGH FRIDAY AS THE STORM SYSTEM SLOWLY PUSHES THROUGH THE AREA.

SATURDAY THE UPPER LEVEL RIDGE IS EXPECTED TO PUSH EAST INTO THE
AREA...BRING WARMER TEMPERATURES AND DRY WEATHER THROUGH THE
WEEKEND INTO THE START OF THE WORK WEEK. TUESDAY AN UPPER LEVEL
SHORTWAVE IS EXPECTED TO FLATTEN THE RIDGE AND PRODUCE RAIN ACROSS
THE AREA THROUGH WEDNESDAY.

.AVIATION...

FOR THE 00Z TAF PACKAGE...PRIMARY FORECAST CHALLENGE CONTINUES TO
BE SCT TSRA THAT WILL PERSIST THIS EVENING AND LIKELY INTO THE
OVERNIGHT HOURS. ANY MVFR OR IFR VIS/CIG WILL BE ASSOCIATED WITH
TSRA ACTIVITY AND NOT WORTHY OF MORE THAN A TEMPO. TSRA ACTIVITY
SHOULD SHIFT TO THE EAST OF THE AERODROMES FRIDAY MORNING. WINDS
WILL BE VARIABLE TONIGHT...BECOMING WESTERLY BY FRIDAY AFTERNOON.
