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.

Area forecast discussion, Aug 20, 6:34 PM CDT, 1 hour 49 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
634 PM CDT SAT AUG 20 2011

...UPDATE TO AVIATION...

.DISCUSSION...

SHORT TERM...(TONIGHT AND SUNDAY)

ACCORDING TO THE VARIOUS MESOSCALE MODELS AVAILABLE...THE BEST
WINDOW OF OPPORTUNITY FOR STORMS WILL BE FROM 21Z TO 03Z WITH
INITIATION AROUND THE 20Z TIME FRAME. PINPOINTING INITIATION
LOCATION REMAINS TOUGHEST...AND STILL PREFER AREAS ALONG/NORTHWEST
OF THE I44 CORRIDOR AND ALONG/WEST OF HIGHWAY 65 FOR INITIATION.
SEVERE POTENTIAL/COVERAGE LOOKS BETTER ALONG/SOUTH OF THE HIGHWAY
60 CORRIDOR WHERE THE BETTER INSTABILITY RESIDES. TO THE
NORTH...STILL CANNOT RULE OUT A FEW SEVERE STORMS...EXPECTATIONS
ARE FOR A LOWER COVERAGE/RISK. PRIMARY RISKS CONTINUE TO BE
DAMAGING WIND GUSTS AND LARGE HAIL. WILL NEED TO MONITOR HAIL
POTENTIAL FOR SIZES LARGER THAN QUARTERS AS NAM SOUNDINGS SUGGEST
PRETTY DECENT MID LEVEL LAPSE RATES.

STORMS SHOULD EXIT TO THE EAST AND SOUTH DURING THE LATE EVENING
HOURS WITH SOME CLEARING EXPECTED OVERNIGHT. EXPECTING NEAR
PERSISTENCE LOW TEMPERATURES IN THE UPPER 60S TO LOWER 70S. SUCH
VALUES WOULD SUPPORT A RISK OF PATCHY FOG GIVEN CROSS OVER
TEMPERATURES IN THE UPPER 60S/LOWER 70S...ESPECIALLY IF WE CAN GET
A DECENT SWATH OF RAINFALL ACROSS THE REGION. WILL REMAIN
CONSERVATIVE FOR THE TIME BEING AND ALLOW AN OPPORTUNITY TO SEE
JUST HOW WIDESPREAD RAINFALL CAN GET THIS AFTERNOON/EVENING. ON
SUNDAY...LOOKS TO BE A QUIET DAY ACROSS THE REGION AS WEAK HIGH
PRESSURE BUILDS IN THE REGION IN A BACK DOOR FASHION. A LIGHT
NORTHEAST WIND AND SLIGHT CUT IN HUMIDITY IS EXPECTED WITH NEAR
AVERAGE HIGHS FOR LATE AUGUST.

GAGAN

LONG TERM...(SUNDAY NIGHT THROUGH FRIDAY)

THE NORTHWEST FLOW WILL KEEP THE WEATHER PATTERN ACTIVE FOR THE
OZARKS WITH PERIODIC CHANCES FOR SCATTERED SHOWERS AND
THUNDERSTORMS THROUGH THE MIDDLE OF NEXT WEEK. THE NEXT SHORTWAVE
WILL MOVE ACROSS LATE MONDAY AFTERNOON/EVENING AND SHOULD DEVELOP ANOTHER
ROUND OF CONVECTION. ANOTHER VIGOROUS SHORTWAVE WILL MOVE ACROSS
THE MIDWEST TUESDAY AFTERNOON INTO TUESDAY EVENING WITH ANOTHER
ROUND OF SHOWERS AND STORMS ON TAP FOR THE OZARKS. THE MAIN THREAT
WITH ANY STRONG STORMS WILL BE THREAT OF DAMAGING WINDS.
TEMPERATURES WILL BE RATHER WARM BEING SLIGHTLY ABOVE AVERAGE FOR
LATE AUGUST.

BY MIDWEEK...A WEAK FRONT MOVES THROUGH AND A SURFACE HIGH WILL
BUILDS IN FOR LATTER PART OF THE WEEK. THE UPPER LEVEL RIDGE OF
HIGH PRESSURE WILL ALSO BUILD EAST ACROSS THE OZARKS. THIS WILL
ALLOW FOR A LESS ACTIVE WEATHER PATTERN AND RAIN CHANCES WILL BE
NULL FOR THE END OF THE WEEK WITH TEMPERATURES ABOUT PAR FOR THIS
TIME OF YEAR.

GRIFFIN

&&

.AVIATION...

FOR THE 00Z KSGF...KJLN AND KBBG TAFS...MAIN AVIATION CONCERNS
WILL BE THIS EVENING AS SCATTERED THUNDERSTORMS TRACK EAST ACROSS
SOUTHERN MISSOURI EARLY THIS EVENING. THIS ACTIVITY DEVELOPED EAST
OF THE KJLN SITE AND WILL NOT AFFECT THIS SITE OVERNIGHT BUT THIS
SCATTERED ACTIVITY MAY AFFECT THE KSGF AND KBBG SITES. THESE
STORMS MAY BE STRONG TO SEVERE WITH LARGE HAIL AND STRONG AND
GUSTY WINDS POSSIBLE. VISIBILITIES AND CEILINGS WILL ALSO BE
REDUCED WITHIN ANY THUNDERSTORM.

IF THE CLOUDS CAN CLEAR OUT OVERNIGHT FOG DEVELOPMENT WILL BE
POSSIBLE. THEN LIGHT WINDS AND VFR CONDITIONS ARE EXPECTED
THROUGH THE DAY ON SUNDAY.

LAWRENCE-CHRISTIAN-DOUGLAS-HOWELL-SHANNON-MCDONALD-BARRY-STONE-
TANEY-OZARK-OREGON-
103 PM CDT SAT AUG 20 2011

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

.DAY ONE...THIS AFTERNOON AND TONIGHT.

WEATHER HAZARDS EXPECTED...

  ELEVATED THUNDERSTORM WIND DAMAGE RISK.
  ELEVATED HAIL RISK.
  LIMITED LIGHTNING RISK.
  LIMITED FLASH FLOOD RISK.
  ELEVATED EXTREME HEAT RISK.

DISCUSSION...

HEAT INDEX VALUES WILL RANGE FROM THE MIDDLE 90S TO AROUND 103
DEGREES IN AREAS ALONG AND SOUTH OF THE HIGHWAY 60 CORRIDOR...
WITH HIGHEST VALUES EXPECTED ACROSS FAR SOUTHWEST MISSOURI.

A COLD FRONT ENTERING THE AREA FROM THE NORTH WILL BE A FOCUS FOR
THUNDERSTORM DEVELOPMENT THIS AFTERNOON. THUNDERSTORMS INITIATION
IS PREFERRED FOR AREA ALONG AND NORTH OF THE INTERSTATE 44
CORRIDOR AND ALONG AND WEST OF THE HIGHWAY 65 CORRIDOR THIS
AFTERNOON...AND THIS ACTIVITY WILL SPREAD TO THE SOUTHEAST AND
ACROSS THE REMAINDER OF THE OUTLOOK AREA THIS EVENING.

SCATTERED STRONG TO SEVERE THUNDERSTORMS ARE EXPECTED ACROSS THE
ENTIRE OUTLOOK AREA FROM THE MIDDLE OF THIS AFTERNOON THROUGH THE
MID EVENING HOURS. THE BETTER RISK FOR SEVERE THUNDERSTORMS WILL
RESIDE ALONG AND SOUTH OF THE HIGHWAY 60 CORRIDOR WHERE THE
GREATEST INSTABILITY WILL BE LOCATED. THE PRIMARY SEVERE WEATHER
RISKS ARE DAMAGING WIND GUSTS AND LARGE HAIL. DUE TO RECENT HEAVY
RAINFALL ACROSS CENTRAL MISSOURI AND THE EASTERN OZARKS...THERE IS
A LIMITED RISK FOR FLASH FLOODING ALONG AND EAST OF A LINE FROM
OSCEOLA TO WEST PLAINS. THUNDERSTORMS SHOULD EXIT SOUTHERN AND
SOUTH CENTRAL MISSOURI LATE THIS EVENING INTO OVERNIGHT TONIGHT AS
A COLD FRONT MOVES THROUGH THE AREA.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.

ADDITIONAL THUNDERSTORM CHANCES WILL BE POSSIBLE FROM SUNDAY INTO
NEXT WEEK AS SEVERAL UPPER LEVEL DISTURBANCES PUSH THROUGH THE
REGION.

HEAT INDEX VALUES FROM THE MID 90S TO AROUND 100 DEGREES ARE
EXPECTED ACROSS EXTREME SOUTHEAST KANSAS AND MUCH OF THE MISSOURI
OZARKS EACH AFTERNOON FROM SUNDAY THROUGH WEDNESDAY.

.SPOTTER INFORMATION STATEMENT...

 SPOTTER ACTIVATION WILL BE NEEDED IN AREAS ROUGHLY ALONG AND
 NORTHWEST OF THE INTERSTATE 44 CORRIDOR AND ALONG AND WEST OF THE
 HIGHWAY 65 CORRIDOR THIS AFTERNOON. SPOTTER ACTIVATION MAY BE
 NEEDED ACROSS THE EASTERN OZARKS AND SOUTH CENTRAL MISSOURI THIS
 EVENING.
