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, 1.1 hours before the alert went out and 169 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.

Area forecast discussion, Jun 10, 4:40 PM CDT, 3 hours 28 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
440 PM CDT TUE JUN 10 2003

MAIN CONCERN THE NEXT COUPLE OF DAYS CONTINUES TO BE THE CONVECTIVE
THREATS. MAIN CONCERN IN THE SHORT TERM IS ACROSS THE SOUTHERN CWA.
WEAK COLD FRONT WAS LOCATED ACROSS THE EXTREME SOUTHERN PORTION OF
THE METRO AREA NORTHEAST TO A LITTLE SOUTHEAST OF KIRKSVILLE. AIR
MASS AHEAD OF FRONT CONTINUES TO BE QUITE UNSTABLE. THE FRONT WILL
CONTINUE TO TRIGGER STRONG TO SEVERE THUNDERSTORMS DURING THE
EVENING HOURS AS THE FRONT MOVES SLOWLY SOUTHEAST. AIR MASS TO
SLOWLY STABILIZE BY LATE EVENING...BUT SHOWERS AND THUNDERSTORMS TO
CONTINUE ACROSS THE EXTREME SOUTHERN ZONES AHEAD OF UPPER LEVEL TROF
MOVING EAST ACROSS OKLAHOMA.

MODELS CONTINUE TO SHOW TREND OF UPPER TROF SHEARING EAST LATE
TONIGHT WITH ONLY A SMALL THREAT OF SHOWERS ACROSS SOUTHEASTERN
ZONES DURING THE MORNING HOURS ON WEDNESDAY. FRONT STILL LOCATED
ACROSS SOUTHERN CWA ON WEDNESDAY...BUT SLOWLY DISSIPATES DURING THE
DAY. AIR MASS WEAK TO MODERATELY UNSTABLE...BUT AREA UNDER UNDER
SUBSIDENCE BEHIND UPPER SHORTWAVE IN EASTERN MISSOURI.

BY LATE WEDNESDAY AFTERNOON...THE NEXT IN THE SERIES OF SHORTWAVE
TROFS ENTERS THE NORTHERN PLAINS. WILL LIKELY SEE DEVELOPMENT ACROSS
WESTERN NEBRASKA AHEAD OF SURFACE TROF. THIS ACTIVITY MAY MOVE INTO
EXTREME NORTHWESTERN ZONES BY DAYBREAK THURSDAY. OTHERWISE...AVN/ETA
SUGGEST THAT WEAK SHORTWAVE/UPPER LOW TO AFFECT AREA
THURSDAY/THURSDAY NIGHT. TIMING UNCERTAIN SO WILL KEEP POPS IN
CHANCE CATEGORY.

OVERALL...PREFER WARMER ETA GUIDANCE.

DB

NO MAJOR CHANGES HAVE BEEN MADE TO THE EXTENDED PORTION OF THE
FORECAST. DETAILS REGARDING SHOWER AND THUNDERSTORM ACTIVITY
CONTINUE TO BE SKETCHY...DUE TO THE UNCERTAINTIES ASSOCIATED WITH
TIMING OF SHORTWAVES SPEEDING THROUGH THE MID/UPPER WESTERLY FLOW.
THE POSITION OF THE FRONTAL BOUNDARY PROGGED TO BE DRAPED ACROSS THE
CENTRAL CONUS AND/OR ANY LINGERING OUTFLOW BOUNDARIES WILL ALSO
COMPLICATE THE FORECAST. SO...WILL MAINTAIN LOW CHANCE POPS THURSDAY
THROUGH SUNDAY UNTIL CONFIDENCE IMPROVES. TEMP-WISE...READINGS ARE
EXPECTED TO BE NEAR CLIMATOLOGICALLY NORMAL VALUES.

LS

652 AM...

DID SOME MINOR REVISIONS TO THE FORECASTS. CONCERNED ABOUT FRONTAL
BOUNDARY STILL NORTH OF FORECAST AREA. LITTLE CAP IN PLACE AND
ALTHOUGH SEEING SOME STABILIZATION IN AIR MASS ACROSS NORTHERN
MISSOURI IN WAKE OF OVERNIGHT MCS...EXPECT TO SEE SOME RECOVERY BY
THE TIME THE BOUNDARY HAS ENTERED NORTHWEST MISSOURI BY 18Z. THUS
WILL PULL CHANCES OF STORMS A LITTLE FURTHER NORTH.

PC

330 AM...
MAIN FORECAST CONCERNS IS WITH WHERE BOUNDARY WILL SET UP TODAY AND
REDEVELOPMENT OF STORMS TO TAKE PLACE.  THEN LOCATION OF MCS
DEVELOPMENT TONIGHT AND AGAIN WEDNESDAY NIGHT INTO THURSDAY. ALSO
THE EFFECT ON TEMPERATURES THESE MCS FEATURES WILL HAVE.

IN THE SHORT TERM...CURRENT CONVECTION IS EXPECTED TO BE IN SOUTHERN
HALF OF FORECAST AREA AT START OF DAY. THIS SHOULD LEAVE AN OUTFLOW
BOUNDARY ACROSS SOUTHERN PART OF FORECAST AREA FOR THIS
AFTERNOON...WITH STILL SOME SCATTERED THUNDERSTORMS POSSIBLE IN ITS
VICINITY.  ALSO EXPECTING MORE WIDESPREAD DEVELOPMENT INTO SOUTHWEST
PART OF FORECAST AREA BY LATE IN THE DAY AS SHORT WAVE MOVING EAST
ACROSS SOUTHERN KANSAS AND OKLAHOMA PROVIDES ADDITIONAL LIFT.  MCS
TONIGHT SHOULD MOVE THROUGH SOUTHERN MISSOURI...SO WILL KEEP CHANCES
LOW IN NORTHERN PART OF FORECAST AREA. DURING THE DAY ON
WEDNESDAY...MCS EXITS MISSOURI...THEN WILL HAVE TO WAIT FOR NEXT MCS
TO MOVE OUT OF NORTHERN PLAINS WEDNESDAY NIGHT AS ANOTHER SHORT WAVE
MOVES THROUGH IN THE NORTHERN STREAM. WILL LEAVE THUNDERSTORMS
THROUGHOUT FORECAST AREA DURING DAY ON THURSDAY AS SURFACE FRONT
ASSOCIATED WITH THE NORTHERN STREAM WAVE SETTLES ACROSS FORECAST
AREA.

FOR TODAY...SHOULD SEE MORE CLOUDINESS SOUTH WITH DYING MCS...SO
EXPECT WARMER TEMPERATURES IN NORTHERN HALF OF FORECAST AREA. THEN
ON WEDNESDAY...850 TEMPERATURES JUMP UP INTO THE 18 DEGREE RANGE.
SHOULD BE WARM ACROSS MOST OF THE FORECAST AREA ALTHOUGH A LITTLE
LINGERING CLOUDINESS IN SOUTHEAST PART MAY HOLD TEMPS DOWN A FEW
DEGREES.

WILL NOT MAKE ANY SIGNIFICANT CHANGES TO FORECAST BEYOND THURSDAY
TIMEFRAME.

PC

950 PM...
AM MAKING SOME CHANGES TO EXPECTED WEATHER FOR TONIGHT/TUESDAY.
BASED UPON CURRENT SATELLITE/RADAR TRENDS AND 00Z MESOETA RUN BEST
BET FOR THUNDERSTORMS TONIGHT WILL BE ACROSS NORTHERN HALF OF MO.
CORFIDI VECTORS/THICKNESS CONTOURS INDICATE CENTRAL/NORTHEAST NE
WILL TRACK NORTHEAST AND MOVE INTO NORTHWEST/NORTH CENTRAL MO AFTER
MIDNIGHT. ACTIVITY PROGGED TO REACH THE MO RIVER AROUND 12Z. WILL
LOWER POPS OVER SOUTHWESTERN COUNTIES TO CHANCE CATEGORY. HAVE ALSO
INCREASED POPS OVER SOUTHERN 1/3 CWA FOR 12Z-16Z TIME FRAME ACROSS
FAR SOUTHERN COUNTIES TO ACCOUNT FOR MCS MOVING THROUGH. STILL
EXPECT REGENERATION OF AFTERNOON CONVECTION ACROSS ALL BUT FAR
NORTHWEST MO TOMORROW.
