The radar

The Memphis radar (KNQA), 190 km from the middle of the area, began a volume at 17:57 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 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, 5.9 hours before the alert went out and 225 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 Jun 6, 11:53 AM CDT, 1 hour 1 minute earlier.

Area forecast discussion, Jun 6, 11:53 AM CDT, 1 hour 1 minute before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
1153 AM CDT MON JUN 6 2005

.DISCUSSION...

...MESOSCALE CONVECTIVE DISCUSSION...

CONVECTIVE COMPLEX MOVING ACROSS THE MID MISSOURI REGION CONTINUES
TO REMAIN FAIRLY STEADY STATE WITH NEW UPDRAFTS FAVORING THE EASTERN
AND SOUTHWEST FLANKS. GIVEN EXISTING COLD POOL OVER THIS REGION FROM
EARLIER CONVECTION (SFC TEMPS IN THE MID 60S)...ELEVATED PULSE
CONVECTION WILL CONTINUE WITH ONLY ISOLATED SMALL HAIL POSSIBLE.

MEANWHILE...OUTFLOW FROM THIS COMPLEX HAS LAID OUT ACROSS EXTREME
SOUTHEAST KANSAS AND SOUTHERN MISSOURI. MESONET OBSERVATIONS AND
VISIBLE SATELLITE IMAGERY SHOW THIS BOUNDARY IS VERY WELL
DEFINED...AND HAS BECOME QUASI-STATIONARY FROM PITTSBURG KANSAS TO
BRANSON...WHILE MAINTAINING A SE MOVEMENT FURTHER EAST ACROSS SOUTH
CENTRAL MISSOURI.

AIRMASS ALONG AND SOUTH OF THIS BOUNDARY CONTINUES TO UNDERGO STRONG
DAYTIME HEATING WITH TEMPS NOW IN THE MID 80S...ALONG WITH IMPROVED
MOISTURE QUALITY WITH DEWPOINTS IN THE MID-UPPER 60S. 12Z
SPRINGFIELD SOUNDING SHOWS THAT MID LEVEL INVERSION FROM YESTERDAY
HAS BEEN EFFECTIVELY REMOVED...WITH MODIFIED PARCELS YIELDING AROUND
2000 J/KG OF UNINHIBITED MLCAPE. STRONG BOUNDARY LAYER CONVERGENCE
ALONG THIS BOUNDARY...COUPLED WITH THE REMNANTS OF A CONVECTIVE
VORTEX MOVING OVER EASTERN OKLAHOMA WOULD SUPPORT THUNDERSTORM
DEVELOPMENT OVER SW/SRN MO INTO SE KS THIS AFTERNOON.

CURRENT SURFACE OBSERVATIONS AND MDT CUMULUS/CONGESTUS ALONG THE
BOUNDARY WOULD WOULD SUGGEST THAT INITIATION MAY OCCUR WITHIN THE
NEXT COUPLE HOURS. VERY POOR VERTICAL SHEAR PER NEODESHA KS PROFILER
(< 10 KNOTS) WILL RESULT IN SHORT-LIVED PULSE CONVECTION WITH
MARGINALLY SEVERE HAIL THE MAIN THREAT.

.AVIATION...
FOR THE 18Z TAFS...WILL MAINTAIN VFR CONDITIONS AT THIS TIME. A
CHANCE OF THUNDERSTORMS IS POSSIBLE THOUGH COVERAGE IS A QUESTION AS
OUTFLOW BOUNDARY FROM MORNING CONVECTION STILL IN THE AREA. THUS A
CHANCE OF CONVECTION NOTED IN SGF AND JLN TAFS FOR THIS AFTERNOON.
GENERALLY THOUGH...VFR CONDITIONS WILL PREVAIL WITH BORDERLINE MVFR
CONDITIONS WITH ANY CONVECTION THAT DEVELOPS.

TANEY-OZARK-OREGON-
1050 AM CDT MON JUN 6 2005

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

.DAY ONE...TODAY AND TONIGHT.

  WEATHER HAZARDS EXPECTED:

  SCATTERED TO NUMEROUS THUNDERSTORMS...A FEW MAY CONTAIN:
    HAIL TO THE SIZE OF NICKELS.
    HEAVY RAIN.
    AND FREQUENT CLOUD TO GROUND LIGHTNING.

  AREAS AFFECTED AND TIMING:

  SCATTERED TO NUMEROUS THUNDERSTORMS WILL CONTINUE THROUGH NOON TIME
  ALONG AND NORTH OF A STOCKTON TO LEBANON TO SALEM LINE.

  ADDITIONAL THUNDERSTORM DEVELOPMENT IS EXPECTED THIS AFTERNOON
  ALONG AN OUTFLOW BOUNDARY WHICH STRETCHES FROM PITTSBURG KANSAS TO
  MOUNT VERNON TO WEST PLAINS.

  DISCUSSION:

  A COMPLEX OF THUNDERSTORMS WILL PERSIST ACROSS PORTIONS OF MID
  MISSOURI AND THE LAKE OF THE OZARKS REGION THROUGH EARLY THIS
  AFTERNOON...EXTENDING AS FAR WEST AS THE STOCKTON LAKE REGION.
  FREQUENT LIGHTNING AND POSSIBLY SOME SMALL HAIL WILL OCCUR WITH
  THIS ACTIVITY.

  AN OUTFLOW BOUNDARY FROM THIS COMPLEX HAD SETTLED ACROSS SOUTHERN
  MISSOURI AND EXTREME SOUTHEAST LATE THIS MORNING. STRONG HEATING
  AND CONVERGENCE WAS OCCURRING ALONG THIS BOUNDARY...WHICH IS
  EXPECTED TO RESULT IN THUNDERSTORM DEVELOPMENT DURING THE NEXT
  SEVERAL HOURS. THE GREATEST COVERAGE OF THUNDERSTORMS WILL BE
  ALONG AND JUST NORTH OF THIS BOUNDARY...GENERALLY ALONG AND NORTH
  OF A LINE FROM PITTSBURG KANSAS TO MOUNT VERNON TO GAINESVILLE.

  DESPITE STRONG INSTABILITY...WEAK WIND FIELDS WOULD SUGGEST THAT
  THESE STORMS WILL BE RELATIVELY SHORT LIVED...AND CAPABLE OF
  PRODUCING BRIEF DOWNPOURS AND HAIL UP TO NICKEL SIZE.

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

  NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.

.SPOTTER INFORMATION STATEMENT...

  DUE TO THE ISOLATED NATURE OF THE STRONGER STORMS...SPOTTER
  ACTIVATION IS NOT ANTICIPATED AT THIS TIME.
