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.

LINEAR MCS LOCATED OVER NORTH CENTRAL OKLAHOMA AND WAS SHIFTING
EAST ACROSS NORTHERN OKLAHOMA EARLY THIS MORNING. ADDITIONAL
CONVECTION HAS LIFTED NORTHEAST OVER CENTRAL MISSOURI AND WAS NOW
LOCATED MAINLY NORTH OF INTERSTATE 70. SURFACE LOW WAS LOCATED
OVER SOUTH CENTRAL KANSAS WITH DRY LINE EXTENDING SOUTH INTO
NORTHWEST TEXAS. UPPER LEVEL ENERGY CONTINUE TO SHIFT SOUTHWEST TO
NORTHEAST OVER THE PLAINS AND LOW LEVEL JET HAS AIDED IN ONGOING
CONVECTION OVER OKLAHOMA AND NORTHERN MISSOURI.

MAIN FOCUS WILL BE WITH CONVECTION TODAY INTO FRIDAY AS A FRONTAL
BOUNDARY AND PIECES OF UPPER LEVEL ENERGY TRACK THROUGH THE
FORECAST AREA.

&&

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 230 AM CDT THU MAY 9 2013

HIGHEST POPS WILL LIKELY OCCUR THIS MORNING OVER FAR WESTERN
SECTIONS OF THE CWA AS THE REMNANTS OF THE MCS TRACK INTO THE
AREA. THIS SHOULD TRACK EAST ACROSS THE FORECAST AREA THIS
MORNING. THE LOW LEVEL JET SHOULD BE DIMINISHING TOWARDS MID
MORNING AND THE PRECIPITATION COVERAGE AND INTENSITY SHOULD BE
WANING BY THAT POINT. FOR THE SECOND HALF OF THE DAY...MORE
SCATTERED SHOWERS/THUNDERSTORMS WILL BE POSSIBLE WITH MODERATE
INSTABILITY AND EMBEDDED UPPER LEVEL ENERGY MOVING ACROSS THE
AREA. SHEAR AND INSTABILITY LOOK TOO WEAK FOR ANY SEVERE WEATHER.

FOR TONIGHT...FRONTAL BOUNDARY WILL BEGIN TO SWING SOUTHEAST INTO
THE NORTHWEST PORTION OF THE CWA. WOULD EXPECT THE BEST CHANCES OF
PRECIPITATION TO OCCUR ALONG/AHEAD OF THE FRONT. HAVE THE HIGHEST
QPF TOTALS OVER SOUTHWEST MISSOURI THEN SPREADING EAST ALONG THE
MISSOURI/ARKANSAS BORDER OVERNIGHT.

.LONG TERM...(FRIDAY THROUGH WEDNESDAY)
ISSUED AT 230 AM CDT THU MAY 9 2013

UPPER LEVEL TROUGH AND COLD FRONT WILL SWING THROUGH THE AREA ON
FRIDAY WITH THE BULK OF THE PRECIPITATION OCCURRING AHEAD OF THESE
FEATURES AND THE HIGHEST POPS OVER SOUTH CENTRAL MISSOURI.
PRECIPITATION CHANCES WILL EVENTUALLY SHUT DOWN FROM NORTHWEST TO
SOUTHEAST ON FRIDAY/FRIDAY NIGHT BUT COULD SEE SOME LIGHT SHOWER
ACTIVITY AGAIN ON SATURDAY AS A SECONDARY FRONT/SHORTWAVE PUSH
THROUGH. A COOLER AIR MASS WILL MOVE IN BEHIND THIS SECONDARY
FRONT SATURDAY NIGHT AND COULD SEE SOME UPPER 30S TO LOW 40S FOR
LOWS SUNDAY MORNING.

THE COOL DOWN SHOULD BE SHORT-LIVED THIS TIME WITH THE SURFACE
RIDGE SHIFTING SOUTH OF THE AREA AND UPPER LEVEL RIDGING BUILDING
IN FROM THE WEST THROUGH THE FIRST PART OF NEXT WEEK.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z THURSDAY NIGHT)
ISSUED AT 1208 AM CDT THU MAY 9 2013

AN ORGANIZED AREA OF SHOWERS AND THUNDERSTORMS IS EXPECTED TO PUSH
EAST THROUGH WESTERN MISSOURI FROM AROUND DAWN THROUGH THE MID
MORNING HOURS. MVFR VISIBILITIES ARE EXPECTED WITH ANY STORMS. THE
ONLY OTHER AVIATION IMPACT OVERNIGHT WILL BE LOW LEVEL WIND SHEAR
AT KJLN. REDEVELOPMENT OF SHOWERS AND THUNDERSTORMS WILL THEN BE
POSSIBLE FROM LATER THURSDAY AFTERNOON INTO THURSDAY EVENING. THIS
ACTIVITY WOULD BE MORE SCATTERED IN NATURE...THUS WE HAVE COVERED
THIS POTENTIAL IMPACT WITH A PROB30 GROUP AT ALL THREE SOUTHWEST
MISSOURI AERODROMES.
