The radar

The Vance AFB radar (KVNX), 62 km from the middle of the area, began a volume at 12:42 UTC, the scan nearest the moment this went out.

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
NATIONAL WEATHER SERVICE WICHITA KS
637 AM CDT FRI JUN 12 2009

.AVIATION...12Z TAFS KRSL/KSLN/KHUT/KICT/KCNU
PRIMARY FOCUS IS ON TSRA POTENTIAL...ESPECIALLY THIS MORNING. AT
620 AM CDT/1120 UTC...THERE WERE 2 AREAS OF SIGNIFICANT TSRA
AFFECTING...OR WILL AFFECT...CNTRL & SC KS. THE FIRST SUCH AREA
THAT IS MOVING SE25KTS TOWARD SC KS WILL AFFECT THE KICT VICINITY
THRU 12/15Z...HOWEVER THE STRONG/SEVERE TSRA WILL PASS SW-S OF THE
TERMINAL DURING 12/12-12/15Z PERIOD...TAKING AIM AT OK-BORDERING
COUNTIES. IN THE WAKE OF THIS 1ST ROUND OF TSRA IS A LINE OF
STRONG TSRA SURGING ESE25 ACROSS WRN KS. THIS LINE OF STRONG TSRA
WILL IMPACT KRSL THRU 12/15Z DURING WHICH W/NW 30KT GUSTS ARE
POSSIBLE AS THIS LINE APPROACHES. WILL NEED TO KEEP A CLOSE WATCH
ON THE SE PROGRESS OF THIS 2ND AREA OF TSRA AS IT VENTURES TOWARD
SC KS...ESPECIALLY AS IT APPROACHES KHUT.

&&

.PREV DISCUSSION... /ISSUED 317 AM CDT FRI JUN 12 2009/

DISCUSSION...

TODAY:

MAIN FOCUS IS THIS PERIOD IS POTENTIALLY SEVERE WEATHER AND POOR
MODEL HANDLING OF ONGOING STORMS. THE MORE DISCRETE CELLS IN
SOUTHWEST KS APPEAR TO BE ROUGHLY FOCUSED ALONG 850MB BAROCLINIC
ZONE EVIDENT IN 0000 UTC UPPER AIR ANALYSIS. PROFILERS/VWP SHOW
CONVERGENCE CYCLONIC FLOW WEST OF I-35 AND ANTICYCLONIC TO THE
EAST. IT APPEARS THAT MODELS ARE INCORRECTLY REORIENTING THE
THERMAL FIELD EARLY ON WHICH IS AFFECTING RESULTANT OUTPUT. WITH
FLOW BEING RELATIVELY LIGHT...WOULD NOT EXPECT LARGE CHANGES IN
FIELD OTHER THAN EFFECTS FROM CONVECTION. CURRENT THINKING IS
STORMS WILL CONTINUE TO TRACK EAST SOUTHEAST. STORMS SHOULD REMAIN
STRONG-SEVERE THROUGH AT LEAST A EWK-ICT-EGT LINE. BASED ON
CURRENT LOW LEVEL FLOW...LESS SURE TO THE EAST OF THERE...ALTHOUGH
CURRENT MID LEVEL FLOW WOULD STILL BE FAVORABLE FOR HAIL IF
STORMS CAN PERSIST. GIVEN MODEL ISSUES EARLY ON...HARD PRESSED TO
KNOW FOR CERTAIN AMOUNT OF INSTABILITY PRESENT. HOWEVER DO SUSPECT
AT LEAST GRUNGE PRECIPITATION WILL LINGER INTO SOUTHEAST KS WELL
INTO THE MORNING...IF NOT INTO THE AFTERNOON. HAVE TEMPERED MAXES
DOWN A BIT IN SOUTHEAST KS TO ACCOUNT FOR MORE CLOUDS. MEANWHILE...MCS
APPEARS TO BE DEVELOPING FROM SOUTHEAST NEBRASKA INTO EASTERN
COLORADO WHICH...PER MODELS...WILL LIKELY TRACK EAST/EAST-SOUTHEAST
ACROSS NORTHERN KS. HOW THAT WILL PLAY OUT GIVEN THIS EARLIER
CONVECTION REMAINS TO BE SEEN. DO SUSPECT WESTERN SECTIONS WILL
SEE AT LEAST PARTIAL CLEARING THIS AFTERNOON.

TONIGHT:

WILL LINGER PRECIPITATION IN FAR SOUTHEAST KS EARLY THIS
EVENING...ALTHOUGH CONFIDENCE IS NOT THAT HIGH. BETTER CHANCES
SHOULD OCCUR IN THE NORTH AS HIGH PLAINS PRECIPITATION ROLLS
DOWNHILL LATER TONIGHT.

SAT:

WITH WEAK RIDGING AT SURFACE-700MB MOVING ACROSS THE AREA...CHANCES
FOR PRECIPITATION DO NOT APPEAR TO BE WORTH MENTIONING. WITH
MOISTURE GRADIENT ACROSS NORTHERN OK...STAGE IS SET FOR MORE
PRECIPITATION SAT NIGHT AS RETURN FLOW DEVELOPS IN WAKE OF RIDGE.

SUN-THU:

NO CHANGES TO GOING FORECAST. -HOWERTON

AVIATION...06Z TAFS KRSL/KSLN/KHUT/KICT/KCNU
LOW CLOUDS ARE EXPECTED OVERNIGHT...ALONG WITH SOME
RAIN/THUNDERSTORMS MAINLY FOR KRSL...KHUT AND KSLN TAF SITES.
CHANCES FOR RAIN OVERNIGHT WILL DIMINISH TOWARD THE EAST...WHERE
THE PRECIPITATION CHANCES WILL BE GREATER DURING THE MORNING.
CEILINGS WILL EVENTUALLY LIFT BY LATE IN THE AFTERNOON OR EARLY
EVENING...WITH SOME CIRRUS REMAINING THROUGH THE END OF THE TAF
PERIOD.
