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 severe thunderstorm 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 197 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 severe thunderstorm 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 severe thunderstorm warning went out at Mar 10, 6:21 PM CDT, 17 minutes earlier.

Area forecast discussion, Mar 10, 6:21 PM CDT, 17 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
621 PM CDT TUE MAR 10 2009

...MESOSCALE CONVECTIVE DISCUSSION...

.UPDATE...

A COLD FRONT STRETCHED FROM NEAR ST. LOUIS SOUTHWEST TO BRANSON AT
6 PM. CONVECTION HAD INCREASED ALONG THE FRONT WITH POST FRONTAL
SHOWERS EXTENDING 60-80 MILES BEHIND THE FRONT. MODEST INSTABILITY
CONTINUES TO BE A LIMITING FACTOR DESPITE FAVORABLE WIND SHEAR
PARAMETERS. INSTABILITY HAD INCREASED TO NEAR 500 J/KG ACROSS FAR
SOUTH CENTRAL MISSOURI. SO THERE IS STILL A SLIGHT RISK OF A SEVERE
STORM SOUTHEAST OF A LINE FROM SALEM TO BRANSON. DAMAGING WINDS
WILL BE THE PRIMARY RISK WITH ANY SEVERE STORMS THAT MAY DEVELOP.

FOSTER

&&

.DISCUSSION...

MAIN CONCERNS IN THE NEAR TERM ARE SEVERE THUNDERSTORM
CONCERNS...THEN TEMPERATURES BECOME A CONCERN AS WINTER
MAKES A RETURN.

A STRONG COLD FRONT EXTENDS FROM EASTERN IA INTO WEST CENTRAL MO
AND FAR SOUTHEAST KS. TEMPERATURES HAVE WARMED INTO THE 70S AHEAD
OF THE FRONT WITH SFC DEW POINTS IN THE MID AND UPPER 50S. NAM
BUFR SOUNDINGS SEEM TO HAVE A GOOD HANDLE ON THE LOCAL/REGIONAL
THERMODYNAMIC ENVIRONMENT. MLCAPES FROM POINT SOUNDINGS OVER THE
EASTERN OZARKS REACH UP TO 700-900 J/KG LATER THIS AFTERNOON. EXPECT
THAT A VERY WEAK CAP IN PLACE WILL BREAK WITHOUT MUCH TROUBLE AS A
SHORTWAVE OVER THE CENTRAL HIGH PLAINS SWINGS NORTHEAST INTO
EASTERN NEB/WESTERN IA BY 00Z. SFC LOW WILL DEEPEN OVER THE UPPER
MIDWEST IN RESPONSE TO THE APPROACHING SHORTWAVE...AND THE COLD
FRONT WILL BEGIN TO SURGE EAST THIS AFTERNOON. LOW TO MODERATE
INSTABILITY...BUT ABUNDANT SHEAR...WITH 0-6KM BULK SHEAR IN THE
NEIGHBORHOOD OF 70KTS...WILL ALLOW AN ORGANIZED LINE OF STORMS TO
DEVELOP ALONG THE FRONT. PRIMARY THREAT WILL BE DAMAGING
WINDS...BUT SOME MARGINALLY SEVERE HAIL WILL BE POSSIBLE WITH
STRONGER UPDRAFTS. THE SFC WINDS ARE ALREADY VEERED TO THE SW AND
SSW AHEAD OF THE FRONT...BUT GIVEN THE SHEAR CANT RULE OUT EMBEDDED
SUPERCELL STRUCTURES WITHIN THE LINE WITH A LOW END ISOLATED
TORNADO THREAT.

THE FRONT AND ANY ASSOCIATED STORMS WILL SURGE ESE THROUGH THE MO
OZARKS LATE THIS AFTERNOON AND EVENING...AND SHOULD EXIT THE
EASTERN CWFA/SOUTH CENTRAL MO BY AROUND 03Z. VERY COLD SFC
TEMPERATURES NOTED UPSTREAM OVER NORTHERN KS AND NEB...AND HAVE
GONE WITH THE MUCH COLDER NAM MOS OVER THE GFS MOS. TEMPERATURES
CLOSE TO JANUARY NORMALS ARE EXPECTED THROUGH THURSDAY. SOME
CONCERNS THAT THE NORTHERN FRINGE OF PERSISTENT ISENTROPIC LIFT TO
OUR SOUTH WILL AFFECT SOUTHERN COUNTIES WITH SOME LIGHT PRECIP
OVER THE NEXT COUPLE OF DAYS...ESPECIALLY ON THU...BUT BETTER
CHANCES FOR RAIN WILL OCCUR SATURDAY/SATURDAY NIGHT AS ANOTHER
SHORTWAVE MOVES NORTHEAST THROUGH THE PLAINS. THERE IS FAIRLY GOOD
AGREEMENT WITH ANOTHER MORE VIGOROUS SHORTWAVE MOVING E-ESE THROUGH
THE CENTRAL PLAINS AND MID MS VLY SUNDAY NIGHT/MONDAY
MORNING....BUT THE TIMING AND PLACEMENT OF UPPER LEVEL FEATURES
BECOMES MORE PROBLEMATIC BY LATE MONDAY/TUESDAY. IN SHORT...WHILE
PRECIP CHANCES WILL EXIST AT TIMES THROUGH THE WEEKEND INTO EARLY
NEXT WEEK...RAIN AMOUNTS LOOK TO BE FAIRLY LIGHT. TEMPERATURES
WILL MODERATE SOMEWHAT FRIDAY...BUT AM NOT REALLY EXPECTING
TEMPERATURES TO GET BACK TO NORMAL UNTIL EARLY NEXT WEEK. DSA

&&

.AVIATION...

A COLD FRONT HAD MOVED TO THE EAST OF SPRINGFIELD AT LATE
AFTERNOON. POST FRONTAL SHOWERS WILL IMPACT THE SPRINGFIELD
TERMINAL THROUGH EARLY EVENING BUT END FROM THE WEST. MVFR AND
OCCASIONALLY IFR CEILINGS CAN ALSO BE EXPECTED THIS EVENING. THE
LOWER LEVELS WILL BEGIN DRYING LATER TONIGHT ALLOWING FOR
IMPROVING FLIGHT CONDITIONS BY 06Z. VFR CONDITIONS WILL PREVAIL
WEDNESDAY AS SURFACE HIGH PRESSURE DOMINATES THE REGION.

.SGF WATCHES/WARNINGS/ADVISORIES...

629 PM CDT TUE MAR 10 2009

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

.DAY ONE...TONIGHT.

  WEATHER HAZARDS EXPECTED:

 DAMAGING STRAIGHT LINE WIND GUSTS IN EXCESS OF 60 MPH. HAIL TO
 THE SIZE OF DIMES. AN ISOLATED TORNADO THREAT.

  AREAS AFFECTED AND TIMING:

 THUNDERSTORMS WILL CONTINUE TO DEVELOP ALONG A COLD FRONT THAT
 EXTENDED FROM BRANSON TO ROLLA AT 630 PM. THIS FRONT WILL
 CONTINUE TO SURGE EAST THROUGH THE REST OF THE MISSOURI
 OZARKS...AND INTO SOUTHEAST MISSOURI AND NORTHERN ARKANSAS BY 9
 PM.

  DISCUSSION:

 A WARM AND MOIST AIRMASS EXISTS AHEAD OF A COLD FRONT MOVING
 THROUGH THE MISSOURI OZARKS. WEAK TO MODERATE INSTABILITY...BUT
 STRONG WIND SHEAR...WILL ALLOW THUNDERSTORMS TO CONTINUE TO
 DEVELOP NEAR THE FRONT. AS THE THUNDERSTORMS INTERACT WITH A
 SLIGHTLY MORE UNSTABLE ENVIRONMENT OVER SOUTH CENTRAL
 MISSOURI...DAMAGING STRAIGHT LINE WIND GUSTS AND HAIL TO THE SIZE
 OF DIMES WILL BE THE PRIMARY SEVERE WEATHER HAZARDS. DUE TO THE
 UNUSUALLY STRONG WIND SHEAR...AN ISOLATED TORNADO MAY BE POSSIBLE
 OVER SOUTH CENTRAL MISSOURI.

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

 NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.

.SPOTTER INFORMATION STATEMENT...

 SPOTTER ACTIVATION MAY BE NEEDED OVER THE PARTS OF SOUTH CENTRAL
 MISSOURI THROUGH 9 PM.
