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 Jun 11, 10:32 AM CDT, 57 minutes earlier.

Area forecast discussion, Jun 11, 10:32 AM CDT, 57 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
1032 AM CDT MON JUN 11 2012

...MESOSCALE CONVECTIVE DISCUSSION...

.UPDATE...

LARGE THUNDERSTORM COMPLEX CURRENTLY MOVING THROUGH THE AREA HAS
PRODUCED WINDS IN EXCESS OF 60 MPH IN THE SPRINGFIELD AREA. AS
SURFACE HEATING IS OCCURRING THIS MORNING...STARTING TO SEE THE COLD
POOL AND UPDRAFT BALANCE BEGINNING TO OCCUR WHICH ARE ALLOWING
STRONG MID LEVEL WINDS TO MIX DOWN TO THE SURFACE. AS STORMS MOVE
INTO THE WATCH AREA...WILL START TO SEE BETTER CHANCES OF STRONG
WINDS FROM ABOUT THE ROLLA AREA DOWN TOWARD THE BRANSON AREA
THROUGH ABOUT NOONTIME.

AS THE AFTERNOON PROGRESSES...WILL SEE INSTABILITY INCREASES...
BOTH AT THE SURFACE AND IN THE HAIL GROWTH REGION...THAT WILL MAKE
LARGER HAIL ALSO A THREAT. THIS MORNINGS ACTIVITY HAS ALSO PUT OUT
A BOUNDARY THAT MAY SERVE AS A FOCUS FOR REDEVELOPMENT LATER THIS
AFTERNOON...ESPECIALLY OVER EXTREME SOUTHEAST KANSAS WHICH SAW
LITTLE IN THE WAY OF STORMS THIS MORNING. IF CLEARING OCCURS
BEHIND THIS INITIAL COMPLEX...REDEVELOPMENT WILL ALSO BE POSSIBLE IN
THIS AREA LATER THIS AFTERNOON.

GAEDE

&&

.DISCUSSION...

RATHER COMPLEX AND LOW CONFIDENCE SHORT TERM FORECAST THIS
MORNING...AS FOCUS REMAINS ON CONVECTIVE EVOLUTION AND ASSOCIATED
SEVERE WEATHER POTENTIAL OVER THE NEXT 24 HOURS OR SO.

LOOSELY ORGANIZED CLUSTER OF THUNDERSTORMS OVER NORTHWESTERN
MISSOURI CONTINUES TO SAG EAST SOUTHEAST WITH TIME THIS MORNING...AS
NEW CELLS OCCASIONALLY INITIATE ON THE NOSE OF A WEAK LOW LEVEL JET.
THE ENVIRONMENT REMAINS LARGELY CAPPED TO ANYTHING CLOSE TO A
SURFACE PARCEL...AND THUS EXPECT THIS CLUSTER TO REMAIN VERY
ELEVATED EARLY THIS MORNING. CORFIDI VECTORS SUGGEST THAT THIS
CLUSTER WILL CONTINUE SOUTHEAST...WITH ITS MOTION PERHAPS BECOMING
MORE SOUTHERLY WITH TIME. WITH SUCH A STRONG CAP IN PLACE OVER THE
REGION...I SUSPECT THAT THIS INITIAL AREA OF THUNDERSTORMS WILL
WEAKEN CONSIDERABLY BY/SHORTLY AFTER SUNRISE...AS WHAT WEAK LIFT THE
LOW LEVEL JET IS CREATING DISSIPATES.

THE ACTUAL COLD FRONT REMAINS QUITE FAR TO THE NORTHWEST OF THE
CWA...AND WILL ONLY SLOWLY SAG SOUTH BY MID MORNING...PERHAPS MAKING
IT AS FAR SOUTH AS U.S. 54 BY THE 15-17Z TIME FRAME.  AS SURFACE
HEATING COMMENCES AND ADDITIONAL LOW LEVEL MOISTURE BUILDS NORTH
DURING THE MORNING HOURS...CURRENT EXPECTATIONS ARE THAT SURFACE
CINH WILL ERODE BY MIDDAY/EARLY AFTERNOON ALONG AND SOUTH OF THE
FRONT...WITH THE FRONT AND ANY OUTFLOW BOUNDARIES FROM EARLY MORNING
CONVECTION SERVING AS THE FOCUS FOR ADDITIONAL CLUSTERS OF STORMS.

THE FRONT...PERHAPS REINFORCED BY OUTFLOW...SHOULD MAKE ADDITIONAL
PROGRESS SOUTH DURING THE AFTERNOON HOURS...GRADUALLY MOVING THE
MOST FAVORED AXIS OF CONVECTION TO ALONG AND SOUTH OF THE U.S. 60
CORRIDOR BY MID AFTERNOON...AND TO FAR SOUTHERN MISSOURI/NORTHERN
ARKANSAS BY EARLY EVENING.  THE AIRMASS OVER THIS REGION IS EXPECTED
TO BE QUITE UNSTABLE BY AFTERNOON...WITH RATHER IMPRESSIVE CAPE
EXPECTED THROUGH THE HAIL GROWTH LAYER.  SHEAR CONTINUES TO BE THE
MARGINAL INGREDIENT...THOUGH THE LATEST ITERATIONS OF MODEL GUIDANCE DO
SUGGEST SOMEWHAT HIGHER VALUES THAN WHAT WAS EXPECTED A COUPLE OF
DAYS AGO...AS MUCH AS 30-40 KT AT TIMES (0-6KM LAYER).  THIS SHOULD BE
SUFFICIENT FOR MULTICELL ORGANIZATION THROUGHOUT THE AFTERNOON...AND
MAYBE EVEN A TRANSIENT MID LEVEL MESOCYCLONE OR TWO WITH THE
STRONGEST CELLS.  LARGE HAIL...PERHAPS TO THE SIZE OF GOLF BALLS IN
A FEW INSTANCES...WILL BE THE MOST LIKELY SEVERE WEATHER
HAZARD...ESPECIALLY WITH ANY ROTATING UPDRAFTS.  LOW LEVEL THETA-E
DIFFERENTIALS WILL BE ENOUGH TO RESULT IN A FEW STRONG TO SEVERE
WIND GUSTS AS WELL.

THE EFFECTIVE FRONTAL BOUNDARY AND ANY ASSOCIATED SEVERE WEATHER RISK IS
EXPECTED TO CLEAR THE SOUTHERN REACHES OF THE CWA BY LATE THIS
EVENING...THOUGH A SCATTERED SHOWER OR THUNDERSTORM MAY FLIRT WITH
THE MISSOURI/ARKANSAS STATE LINE OVERNIGHT TONIGHT.  COOLER AND LESS
HUMID AIR WILL BUILD IN BEHIND THE FRONT FOR TUESDAY...WHICH SHOULD
BE A RATHER NICE DAY FOR MOST OF THE AREA.

PLEASANT TEMPERATURES ARE EXPECTED ON WEDNESDAY AS WELL...THOUGH
DEWPOINTS WILL BE ON A SLOW RISE LATE IN THE DAY OVER THE WESTERN
PORTIONS OF THE FORECAST AREA.  ELEVATED CONVECTION MAY DEVELOP OVER
THE GREAT PLAINS VERY LATE TUESDAY NIGHT INTO WEDNESDAY
MORNING...PERHAPS TOUCHING SOUTHEASTERN KANSAS AND FAR SOUTHWESTERN
MISSOURI DURING THE DAY WEDNESDAY.  MOST OF THE CWA LOOKS TO STAY
DRY HOWEVER.

A WARMER AND MORE HUMID AIRMASS IS EXPECTED TO THEN BUILD NORTHEAST
INTO THE REGION FOR THURSDAY...AND ESPECIALLY FRIDAY THROUGH THE
WEEKEND...WITH HIGHS LIKELY TOPPING OUT IN THE MID TO UPPER 80S.
UPPER LEVEL RIDGING WILL PREVENT MUCH IN THE WAY OF FORCING FOR
RAIN/THUNDERSTORMS DURING THIS TIME PERIOD...THOUGH RELATIVELY COOL
MID LEVEL TEMPS (7-8C AT 700 MB) PROGGED BY GUIDANCE IS SUGGESTIVE
OF SCATTERED DIURNAL CONVECTION OVER AT LEAST PARTS OF THE AREA
THROUGH THE WEEKEND.

BOXELL

.AVIATION...
/ISSUED 640 AM CDT MON JUN 11 2012/

FOR THE 12Z TAFS (JLN/SGF/BBG)...PRIMARY FORECAST CHALLENGE
CONTINUES TO BE TIMING OF COLD FRONT AND SHRA/TSRA. CURRENT BAND
OF SHRA/TSRA ACROSS CENTRAL MISSOURI WILL CONTINUE TO SAG SOUTH
WITH TIME AND LOSE A BIT OF ITS PUNCH...WHILE INDIVIDUAL CELLS
DEVELOPING ACROSS SOUTHEAST KANSAS MOVE TO THE EAST AND EVENTUALLY
MERGE WITH THE LINE. TSRA SHOULD INCREASE IN INTENSITY FROM LATE
MORNING TO THE AFTERNOON...POSING A RISK OF STRONG WIND GUST AND
HAIL. HAVE TENTATIVELY TIMED THIS ACTIVITY FOR LATE MORNING
THROUGH THE MID AFTERNOON FOR JLN/SGF...THOUGH THIS MAY NEED TO BE
FURTHER REFINED BASED ON THE BEHAVIOR OF ONGOING ACTIVITY. TIMING
IS A FEW HOURS LATER FOR BBG. CLEARING FROM NORTH TO SOUTH IS
EXPECTED THIS EVENING...WITH AN OUTSIDE CHANCE AT LIGHT FOG TOWARD
DAYBREAK TUESDAY.

1022 AM CDT MON JUN 11 2012

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

.DAY ONE...TODAY AND TONIGHT.

WEATHER HAZARDS EXPECTED...

  ELEVATED HAIL RISK.
  ELEVATED THUNDERSTORM WIND DAMAGE RISK.
  SIGNIFICANT LIGHTNING RISK.
  LIMITED FLOODING RISK.

DISCUSSION...

  A LINE OF STRONG TO SEVERE THUNDERSTORMS WILL IMPACT LOCATIONS
  ALONG AND SOUTH OF THE INTERSTATE 44 CORRIDOR INTO EARLY THIS
  AFTERNOON. THE MAIN THREATS WITH THIS LINE OF STORMS WILL BE
  WIND GUSTS TO 70 MPH...HAIL TO THE SIZE OF PING PONG BALLS...
  TORRENTIAL RAINFALL...AND FREQUENT LIGHTNING STRIKES. THE
  HEAVY RAINFALL MAY RESULT IN SOME BRIEF MINOR FLOODING OF
  POOR DRAINAGE AREAS.

  ADDITIONAL THUNDERSTORMS MAY THEN DEVELOP LATE THIS AFTERNOON
  AND THIS EVENING ALONG AND NORTH OF THE INTERSTATE 44 CORRIDOR
  IF THE ATMOSPHERE CAN DESTABILIZE BEHIND THE MORNING
  THUNDERSTORMS. IF THUNDERSTORMS CAN REDEVELOP...HAIL TO THE
  SIZE OF GOLF BALLS...WIND GUSTS OVER 60 MPH...BRIEF HEAVY
  RAINFALL...AND FREQUENT LIGHTNING STRIKES WILL BE THE MAIN
  THREATS.

  ANY THUNDERSTORMS THAT DEVELOP INTO EARLY THIS EVENING ARE
  EXPECTED TO DIMINISH IN COVERAGE BY LATE THIS EVENING.
  HOWEVER...ISOLATED THUNDERSTORMS WILL BE POSSIBLE ALONG THE
  ARKANSAS STATE LINE THROUGH DAYBREAK TUESDAY.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.

  ISOLATED THUNDERSTORMS WILL BE POSSIBLE EARLY WEDNESDAY OVER
  EXTREME SOUTHEASTERN KANSAS AND FAR SOUTHWESTERN MISSOURI.
  THERE WILL BE ADDITIONAL CHANCES FOR THUNDERSTORMS ON AN
  AFTERNOON BASIS DURING THE END OF THE WORKWEEK THROUGH THE
  WEEKEND. THE CHANCE OF WIDESPREAD SEVERE WEATHER APPEARS LOW AT
  THIS TIME.

.SPOTTER INFORMATION STATEMENT...

  SPOTTER ACTIVATION MAY BE NEEDED IN THE NEXT THREE HOURS FOR
  LOCATIONS ALONG AND SOUTH OF THE INTERSTATE 44 CORRIDOR.

  SPOTTER ACTIVATION MAY THEN BE NEEDED GENERALLY ALONG AND
  NORTH OF THE INTERSTATE 44 CORRIDOR LATE THIS AFTERNOON AND
  THIS EVENING IF THUNDERSTORMS CAN REDEVELOP.
