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.

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 Kansas City, MO wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 30, 6:38 PM CDT, 2 hours 7 minutes earlier.

Area forecast discussion, Jul 30, 6:38 PM CDT, 2 hours 7 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
638 PM CDT FRI JUL 30 2010

...UPDATED AVIATION DISCUSSION...

.DISCUSSION...

A WEAK SHORTWAVE EMBEDDED IN WNW UPPER FLOW HAS TRIGGERED A BAND OF
CONVECTION WHICH HAS NOW SHIFTED IN CNTRL MO. AIR MASS AHEAD OF THE
CONVECTION WAS RATHER UNSTABLE WITH SBCAPES FM 2500-3000 J/KG WITH
25-30 KNOTS OF EFFECTIVE SHEAR. FREEZING LVLS ARE QUITE HIGH WITH WET
MICROBURSTS AND LOCALLY HEAVY RAINFALL THE PRIMARY THREATS. AN
OUTFLOW BOUNDARY STRETCHED ALONG THE I-70 CORRIDOR...BUT FOR THE TIME
BEING...CU FIELDS SUGGEST THAT THERE MAY BE SOME SUBSIDENCE BEHIND
THE SHORTWAVE. HOWEVER...CONVECTION WAS DEVELOPING WELL TO THE WEST
OF TOP...WHERE A FRONTAL BOUNDARY WAS SLOWLY PUSHING EAST. THE VERY
WEAK FRONTAL BOUNDARY STRETCHED FM RSL TO NR FNB. THIS BOUNDARY WILL
SLOWLY SHIFT SE AND SHIFT TO NR THE I-35 CORRIDOR BY AROUND MIDNIGHT.
SFC BASED INSTABILITY WILL DECREASE BY LATE THIS EVENING...BUT THE
BOUNDARY MAY CONTINUE TO TRIGGER THUNDERSTORMS ACR NERN KS TO NWRN MO
WITH THE ACTIVITY SHIFTING SE. THE THREAT OF DAMAGING WINDS WILL
LIKELY END SHORTLY BEFORE MIDNIGHT.

GIVEN THE HIGH PRECIPITABLE WATER...ANY STORM COULD PRODUCE LOCALLY
VERY HEAVY RAINFALL.

THE BOUNDARY WILL DISSIPATE THIS WEEKEND WITH HEIGHTS GRADUALLY
RISING. CANNOT RULE OUT A FEW TSTMS DURING THE AFTN AND EVE HOURS.
OTHERWISE...TEMPS WILL GRADUALLY RISE WITH HEAT INDICES INCREASING.

DB

MEDIUM RANGE (MONDAY THROUGH FRIDAY)...

UPPER LEVEL RIDGE AXIS SHOULD BE CENTERED ACROSS THE SOUTH-CENTRAL
US BY THE BEGINNING OF THE WEEK. NORTHERN STREAM SHORT WAVE TROUGH
WILL SLIDE ACROSS THE GREAT LAKES DURING THE DAY MONDAY BRINGING A
COLD FRONT TOWARD THE AREA. HOWEVER...WITH UPPER RIDGE WILL LIKELY
REMAINING FIRMLY IN PLACE ACROSS THE DEEP SOUTH AND THE BULK OF
ENERGY ASSOCIATED WITH NORTHERN STREAM WAVE REMAINING WELL NORTH OF
THE REGION...EXPECT SURFACE BOUNDARY WILL ONLY MAKE LIMITED
SOUTHWARD MOVEMENT THROUGH MONDAY NIGHT. EXACT BOUNDARY POSITION IS
STILL SOMEWHAT IN QUESTION AND MAY ULTIMATELY BE AUGMENTED BY
MESOSCALE CONVECTIVE PROCESSES. HOWEVER...EXPECTING THE FRONT TO
STALL ACROSS PORTIONS OF IOWA AND NEBRASKA BY MONDAY EVENING. WILL
ONLY MENTION SLIGHT CHC POPS FOR NOW ON MONDAY ACROSS THE NORTHERN
COUNTIES UNTIL MORE CONFIDENCE ON BOUNDARY POSITION IS DETERMINED.

POSITION OF REMNANT BOUNDARY WILL BE KEY IN CONVECTIVE CHANCES
THROUGH THE REMAINDER OF THE WEEK. GIVEN UNCERTAINTY IN FRONTAL
POSITION AND EXPECTED UNSTABLE AIR MASS TO BE IN PLACE...WILL KEEP
SLIGHT CHC MENTION THROUGH THE WEEK FOR MAINLY AFTERNOON AND EVENING
SHOWER/THUNDERSTORM ACTIVITY. OTHERWISE...HOT AND HUMID CONDITIONS
LOOK TO REMAIN IN PLACE AS H850 THERMAL AXIS SLIDES OVERHEAD.

DEROCHE

&&

.AVIATION...

FOR THE 00Z TAFS...SCATTERED SHOWERS AND THUNDERSTORMS HAVE FORMED
ALONG A WEAK COLD FRONT OVER NW MO SINCE 5 PM. EXPECT TO SEE A FEW
SHOWERS AND THUNDERSTORMS FORM WESTWARD ALONG THIS FRONT AND MOVE
THROUGH NORTHEAST KS AND WEST CENTRAL MO THIS EVENING. NOT EXPECTING
A SOLID LINE SO WILL GO WITH CB IN THE TAF AND AMEND IF THE STORMS
INCREASE IN COVERAGE. RISK OF THUNDER WILL END BY LATE EVENING AS
WINDS SHIFT TO THE NORTH AND DRIER AIR FILTERS IN.

SOME LIGHT MVFR FOG IS POSSIBLE DURING THE PRE-DAWN HOURS AT KSTJ
AND KMCI WITH LIGHT WINDS CONTINUED HIGH HUMIDITY. FROM SHORTLY
AFTER SUNRISE AND THROUGH THE REST OF THE FORECAST VFR CONDITIONS
WILL PREVAIL.
