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 00:00Z, 0.5 hours before the alert went out and 118 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 1, 5:45 PM CDT, 1 hour 44 minutes earlier.

Area forecast discussion, Jun 1, 5:45 PM CDT, 1 hour 44 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
545 PM CDT WED JUN 1 2011

...UPDATE TO AVIATION...

.DISCUSSION...

PRIMARY FOCUS FOR THIS FORECAST REMAINED CENTERED ON CHANCES FOR
THUNDERSTORMS TODAY AND HEAT AND HUMIDITY FOR THE REST OF THE WEEK
THROUGH EARLY NEXT WEEK.

SHOWERS AND THUNDERSTORMS WERE DEVELOPING THIS AFTERNOON ALONG THE
WARM FRONT THAT WAS LIFTING SLOWLY NORTH ACROSS NORTHEASTERN
KANSAS AND SOUTHERN MISSOURI. CAPE VALUES AROUND 3000 J/KG ALONG
WITH LITTLE REMAINING OF THE CAP LEFT. THERE WOULD BE THE
POSSIBILITY OF DOWNBURST WINDS AND HAIL UP TO QUARTERS IN SIZE AS
FREEZING LEVELS REMAIN FAIRLY HIGH. WARM AIR AND LOW LEVEL
MOISTURE ADVECTION WILL CONTINUE INTO THIS EVENING WITH THE BEST
CHANCES FOR STORMS ALONG THE FRONTAL BOUNDARY. THE LIMITED FLOW
THROUGH MUCH OF THE COLUMN PRODUCES STORM MOTIONS OF 270 AT 6KTS.
THIS WOULD INDICATE THE POTENTIAL FOR SOME LOCALIZED FLASH
FLOODING AS WELL.

THE FRONT WILL CONTINUE TO LIFT NORTH AS UPPER LEVEL RIDGING BUILDS
OVER THE REGION AND WARM AND HUMID AIR MOVES INTO THE REGION FOR
THE REMAINDER OF THE WEEK AND THROUGH THE WEEKEND. THIS WILL BRING
RATHER SUMMER LIKE CONDITIONS TO THE OZARKS WITH HEAT INDEX VALUES
CLIMBING INTO THE MIDDLE 90S AT TIMES THROUGH THE START OF NEXT WEEK.
LIMITED MID LEVEL MOISTURE WILL ACT TO SUPPRESS CONVECTION THROUGH
MUCH OF THE REMAINDER OF THE WEEK AND INTO THE WEEKEND.
HOWEVER...AN ISOLATED PULSE TYPE STORM OF TWO OR SCATTERED
AFTERNOON SHOWERS ARE NOT OUT OF THE QUESTION...BUT COVERAGE AND
POTENTIAL ARE TOO LIMITED TO PUT IN THE FORECAST AT THIS POINT WITH
NO SIGNIFICANT BOUNDARIES OR FORCING MECHANISMS EXPECTED. SOME MID
LEVEL MOISTURE DOES TRY TO MOVE OVER THE AREA LATE SUNDAY WHICH
COULD PROVIDE FOR A LITTLE MORE CHANCE FOR CONVECTION...BUT WILL
HOLD OF FOR NOW ON ADDING RAIN CHANCES.

THE RIDGE DOES BEGIN TO MOVE ON MONDAY AS A UPPER LEVEL STORM
SYSTEM DIGS ACROSS THE WEST COAST TO START NEXT WEEK. THIS UPPER
LOW..ALONG WITH A REINFORCING ONE LATE TUESDAY...WILL EVENTUALLY
BEGIN TO FLATTEN THE RIDGE AND SHIFT THE PEAK OF THE RIDGE EAST OF
THE OZARKS REGION. WHILE THIS WILL LIKELY NOT LOWER TEMPERATURES
MUCH...IT WOULD PLACE THE REGION IN THE VICINITY OF SOUTHWESTERLY
FLOW AND THE NEXT BEST CHANCE FOR STORMS.

.AVIATION...
/ISSUED 541 PM CDT WED JUN 1 2011/

FOR THE 02/0000Z KSGF/KJLN/KBBG TAFS...ISOLD TSTMS OVER SW MO
SHOULD WEAKEN WITH THE LOSS OF DAYTIME HEATING...OTHERWISE A LOT
OF MID AND HIGH LEVEL CLOUDINESS WILL AFFECT THE REGION OVERNIGHT.
CAN'T RULE OUT SOME LIGHT MVFR FOG/HAZE AT AROUND
SUNRISE 10Z-13Z...OTHERWISE VFR CONDITIONS ARE EXPECTED WITH A
LIGHT S-SE WIND.
