The radar

The Pleasant Hill radar (KEAX), 102 km from the middle of the area, began a volume at 23:34 UTC, the scan nearest the moment this went out.

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 12:00Z, 11.6 hours before the alert went out and 144 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 SPRINGFIELD MO
337 PM CDT WED APR 25 2007

.DISCUSSION...

MESO DISCUSSION...

ACTIVITY DEVELOPING OVER EXTREME SE KS GETTING A LITTLE BETTER
ORGANIZED WITHIN THE PAST HOUR. TO THIS POINT...SEVERE WX REPORTS
UPSTREAM HAVE BEEN OF DIME/PENNY HAIL AND IT APPEARS THAT AVAILABLE
CAPE IN THE -10C TO -30C LAYER IS A LITTLE TOO LOW AND MORE
SUPPORTIVE OF PENNY TO QUARTER HAIL. HAVING SAID THAT...WITH
CONTINUALLY LOWERING FREEZING AND WET BULB ZERO LEVELS...WILL NEED
TO RECALIBRATE HAIL GROWTH POTENTIAL EVERY FEW HOURS.

WHILE PRIMARY ISSUE WILL BE HAIL...TOR RISK IS STILL A CONCERN. LOW
LEVEL CAPE AND 0-1KM SR HELICITY MAXIMIZED OVER NE OK INTO FAR SW
MO. THIS WILL CONTINUE A SLOW SHIFT TO THE NORTHEAST THIS AFTERNOON
WITH 150-200 J/KG IN THE LOWEST FEW KILOMETERS. WITH TEMPS IN THE
LOW TO MID 70S...AND DECENT MID LEVEL LAPSE RATES OVER SW AND S
MO...INCREASING LOW LEVEL HELICITIES ARE A CONCERN. AS A RESULT...
TOR WATCH WILL BE FORTHCOMING UNTIL FROM NEOSHO TO SPRINGFIELD TO
ROBY ON SOUTH.

GAGAN

FORECAST DISCUSSION...

MAIN FOCUS IN THE SHORT TERM WILL BE ONGOING CONVECTION AND SEVERE
WEATHER POTENTIAL THIS EVENING INTO THE OVERNIGHT HOURS.
THUNDERSTORMS HAVE CURRENTLY DEVELOPED OVER EASTERN KANSAS AND
OKLAHOMA...WITHIN THE AREA OF STRONG LOW PRESSURE. THE LOW WILL
CONTINUE TO MOVE TO THE NORTHEAST THROUGH THE REGION THIS EVENING
THROUGH THE OVERNIGHT HOURS. THE SHOWERS AND THUNDERSTORMS WILL MOVE
AND DEVELOP ACROSS THE REGION ALONG THE LOW AS IT PROPAGATES TO THE
NORTHEAST.

THE REGION REMAINS IN THE WARM SECTOR OF THE AREA OF LOW PRESSURE.
THE SUN WAS ABLE TO PEAK OUT TODAY AS THE PRIEST CLOUD DECK THIS
MORNING HAS SCATTERED OUT FROM WEST TO EAST. THIS HAS ALLOWED
WARMING TO OCCUR. CAPE VALUES ARE AROUND THE 1000 J/KG GENERATE WITH
0-3KM CAPE AROUND 150 J/KG. 0-6KM BULK SHEAR IS AROUND 40KTS. WITH
THE SHEAR AND THE LOW LEVEL INSTABILITY...THERE WILL BE A TORNADO
THREAT THIS EVENING...MAINLY SOUTH OF I-44. NOT LOOKING AT A
WIDESPREAD OUT BREAK...BUT CANNOT RULE AT A FEW BRIEF WEAK TORNADOES
THIS EVENING. THE MID LAYERS OF THE ATMOSPHERE WILL CONTINUE TO COOL
THIS EVENING. MID LEVEL LAPSE RATES ARE NOT THAT IMPRESSIVE...
HOWEVER WITH THE SHEAR AND COOL TEMPERATURES ALOFT...SEVERE HAIL UP
TO THE SIZE OF QUARTERS/WALNUTS ARE POSSIBLE.

THE LOW WILL CONTINUE TO TRACK TO THE NORTHEAST TONIGHT AND WILL
BEGIN TO PUSH OUT OF THE AREA TOMORROW AFTERNOON. WRAP AROUND RAIN
WILL BE POSSIBLE OVER THE AREA BEHIND THE LOW MOVES OUT. BY TOMORROW
EVENING THE RAIN CHANCES WILL HAVE MOVED TO THE EAST.

A SHORTWAVE RIDGE WILL BUILD IN BEHIND THIS SYSTEM ON FRIDAY...OUT
AHEAD OF A QUICK MOVING SHORTWAVE. THE SHORTWAVE WILL CLIP THE
WESTERN AND SOUTHERN PORTIONS OF THE CWA. THE GULF WILL REMAIN OPEN
AND SOUTHERLY WINDS WILL CONTINUE TO ALLOW FOR ENOUGH MOISTURE TO
CREATE PRECIPITATION CHANCES FOR FRIDAY NIGHT AND SATURDAY.

SATURDAY AN UPPER LEVEL RIDGE WILL BUILD INTO THE AREA BRINGING
WARMING AND DRY WEATHER INTO THE AREA INTO THE START OF THE WORK
WEEK. HIGHS IN THE UPPER 70S AND 80S WILL ONCE AGAIN OCCUR OVER THIS
TIME FAME. MID WEEK AN UPPER LEVEL LOW OVER THE SOUTHWEST US WILL
MOVE TOWARDS THE AREA BRINGING THUNDERSTORM CHANCE ON WEDNESDAY.

.AVIATION...

FOR THE 18Z TAF PACKAGE...PRIMARY FORECAST CONCERNS REVOLVE AROUND
THUNDERSTORM DEVELOPMENT THIS AFTERNOON. MVFR CIGS HAVE BROKEN AND
LIFTED A BIT WITH MIXING. STILL COULD SEE A TRANSIENT HIGH END MVFR
CIG LEVEL SEEP IN ONCE IN A WHILE...BUT NOT A MAJOR CONCERN. OF MORE
IMPORTANCE IS TSRA BEGINNING TO DEVELOP IN THE WARM SECTOR AHEAD OF
THE SFC LOW OVER SE KS. STORMS HAVE BEGUN TO FIRE AND WILL
EVENTUALLY APPROACH JLN AND SGF THIS AFTERNOON. HAVE MAINTAINED VCTS
WORDING GIVEN UNCERTAINTY IN TIMING...HOWEVER WILL UPDATE AS RADAR
TRENDS DICTATE. HAIL WILL BE A CONCERN WITH THIS ACTIVITY.

TONIGHT...THE UPPER LOW OVER KANSAS WILL SLOWLY...BUT STEADILY...
SHIFT TO THE EAST. LARGE AREA OF INITIALLY MVFR...THEN IFR CIGS HAVE
BEEN OBSERVED WITH THE CLOUD DECK ON THE BACK SIDE OF THIS LOW. HAVE
TAKEN AN INITIAL STAB AT LOWERING CIGS WITH WINDS SHIFTING
OVERNIGHT. HAVE INCLUDED A MENTION OF -SHRA AS WELL. IFR CIGS ARE
EXPECTED TO PERSIST WELL INTO THURSDAY.
