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

Lamont, OK (KLMN), launched 12:00Z, 0.9 hours before the alert went out and 105 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
NATIONAL WEATHER SERVICE DODGE CITY KS
331 AM CDT WED JUL 8 2009

.DISCUSSION...

DAYS 1-2...

A SMALL BAND OF ELEVATED THUNDERSTORMS WAS PERSISTING IN THE AREA
FROM AROUND SCOTT CITY BACK INTO NORTHWEST KANSAS. THIS CONVECTION
APPEARS TO BE AIDED BY UVV DUE TO WARM ADVECTION AND ISENTROPIC LIFT.
THE NAM SHOWS THIS PRETTY WELL AND GRADUALLY MOVES THE AREA TO THE
EAST THROUGH THE EARLY MORNING HOURS. THINK THE AREA OF STORMS WILL
CONTINUE THROUGH SUNRISE SO WILL KEEP SOME ISOLD/WIDELY SCT POPS
GOING ACROSS THE NORTHEAST AND EASTERN CWA THROUGH ABOUT 15Z.

THE UPPER RIDGE CONTINUES TO BUILD OVER THE CENTRAL HIGH PLAINS THROUGH
THURSDAY. A LEE SIDE TROUGH WILL PERSIST ALONG THE KANSAS/COLORADO BORDER
THROUGH THE DAY. THE MODELS HAVE BEEN KEEPING THIS AFTERNOON AND TONIGHT
DRY AND AM INCLINED TO KEEP IT THAT WAY AS CONVERGENCE ALONG THE TROUGH
LOOKS PRETTY WEAK. IN ADDITION...SURFACE DEWPOINTS WILL BE FALLING INTO
THE 30S OVER WESTERN SECTIONS OF THE CWA THIS AFTERNOON AS DRIER AIR
FROM THE EASTERN SLOPES. THE DRIER AIR PLUS HIGH TEMPERATURES TOPPING
OUT AT OR ABOVE 100 THE NEXT FEW DAYS WILL RESULT IN RELATIVE HUMIDITY
FALLING INTO THE LOWER TEENS OVER THE SOUTHWEST PART OF THE CWA. SOME
COOL SEASON GRASSES ARE CURING OUT IN FAR SOUTHWEST KANSAS WHICH RAISES
SOME CONCERN ABOUT WILDLAND FIRES. WINDS ARE NOT EXPECTED TO BE
TOO STRONG TODAY SO DO NOT ANTICIPATE ANY FIRE WEATHER HEADLINES.
WILL MENTION THE INCREASED THREAT IN THE FWF. WILL ALSO MENTION THE
VERY WARM TEMPERATURES AND POTENTIAL FOR HEAT ADVISORY CONDITIONS
ESPECIALLY IN THE SOUTHEAST CWA.

THE MODELS HAVE BEEN FAIRLY CONSISTENT IN SHOWING A FRONTAL BOUNDARY
SLIDING SOUTH INTO WESTERN KANSAS ON THURSDAY. THERE COULD BE ENOUGH
CONVERGENCE ALONG THE FRONT TO GENERATE A FEW HIGH BASED THUNDERSTORMS
BUT AM NOT OVERLY CONFIDENT. FOR NOW WILL INCREASE POPS TO AROUND
10 PERCENT OR SO BUT LEAVE THE FORECAST DRY.

DAYS 3-7...

MEDIUM RANGE MODELS ARE IN GENERAL AGREEMENT INDICATING AN UPPER
LEVEL RIDGE OF HIGH PRESSURE DOMINATING ACROSS THE CENTRAL PLAINS TO
BEGIN THE PERIOD FRIDAY BEFORE BEGINNING TO EDGE BACK TO THE WEST
INTO COLORADO AND NORTHERN NEW MEXICO BY THE END OF THE WEEKEND.
AT THE SURFACE, AN AREA OF LOW PRESSURE WILL PERSIST GENERALLY
ACROSS SOUTHEASTERN COLORADO AND SOUTHWESTERN KANSAS THROUGH THE END
OF THE WEEKEND. MEANWHILE, A WEAK COLD FRONT WILL BEGIN TO SLOWLY
PUSH SOUTH INTO WESTERN KANSAS FRIDAY BEFORE STALLING OUT SOMEWHERE
ACROSS SOUTHWEST KANSAS SATURDAY. HOWEVER, A LOW LEVEL SOUTHERLY
FLOW WILL PREVAIL ACROSS MUCH OF THE CWA THROUGH THE WEEKEND EXCEPT
FOR THE MOST NORTHERN PORTIONS OF THE FORECAST AREA, WHICH WILL BE
JUST NORTH OF THE FRONTAL BOUNDARY. AGAIN, COMBINED WITH THE UPPER
LEVEL RIDGING ALOFT, THIS WILL ALLOW FOR TEMPERATURES TO WARM UP TO
JUST ABOVE THE SEASONAL NORM GOING INTO THE WEEKEND. FOR FRIDAY,
TEMPERATURES WILL BE QUITE WARM WITH BOTH THE GFS AND ECMWF SHOWING
TEMPERATURES AT H85 RANGING IN THE LOWER 30S(C) ACROSS MUCH OF
SOUTHWEST AND SOUTH CENTRAL KANSAS. AS A RESULT, EXPECT HIGHS FROM
AROUND 100F TO NEAR 105F ACROSS THE CWA WITH TEMPERATURES BACKING
OFF SOMEWHAT BUT REMAINING QUITE WARM THROUGH THE REMAINDER OF THE
WEEKEND. PLAN NO SIGNIFICANT CHANGES TO TEMPERATURES. VERY LITTLE IN
THE WAY OF PRECIP IS EXPECTED ACROSS THE FORECAST AREA THROUGH THE
WEEKEND.

&&

AVIATION...

VFR CONDITIONS WILL PREVAIL THROUGH TONIGHT. OTHERWISE, A LEE SIDE
TROUGH OF LOW PRESSURE WILL PERSIST ALONG THE COLORADO BORDER TODAY.
LIGHT SOUTHERLY WINDS THIS MORNING WILL INCREASE TO 15 TO 25KT BY
THIS AFTERNOON BEFORE AGAIN SUBSIDING OVERNIGHT.
