What was reported inside it

Time	Report	Where	Remark
Sep 30, 1:30 PM CDT	TSTM WND GST 55	6 E Lincolnville, KS

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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.

1206 PM CDT SUN SEP 30 2007

.UPDATE...

.AVIATION...18Z TAFS RSL/SLN/HUT/ICT/CNU
COLD FRONT WILL CONTINUE TO ADVANCE RAPIDLY ACROSS SOUTH
CENTRAL/SOUTHEAST KS INTO EARLY THIS EVE...WITH STRONG PRESSURE
RISES OCCURRING IN ITS WAKE ALONG WITH A WIND SHIFT TO W-NW. BEST
CHANCE FOR ANY ORGANIZED CONVECTION WILL BE IN SOUTHEAST KS (CNU
TAF) LATE THIS PM. WILL INCLUDE A VCTS THERE AND MONITOR RADAR TRENDS
IN COVERAGE. WINDS SHOULD DIMINISH RAPIDLY EARLY THIS EVE AS LOW
PRESSURE PULLS NORTHEASTWARD OUT OF EASTERN NEBRASKA.

.PREV DISCUSSION... /ISSUED 1127 AM CDT SUN SEP 30 2007/

UPDATE...

RECENTLY SENT UPDATE TO EXPAND/EXTEND WIND ADVISORY ACROSS CENTRAL
KS. COLD FRONT AS OF 16Z WAS FROM NEAR KHYS TO EAST OF KDDC...TO
KPVX WITH VERY STRONG PRESSURE RISES BEHIND THE FROPA OF 5-6
MB/3HR. FRONT SHOULD REACH KICT AROUND 1830Z. GUSTY WINDS/LOWERING
HUMIDITIES BEHIND THE FRONT WILL RAISE THE RANGELAND FIRE DANGER
TO VERY HIGH TO EXTREME ACROSS CENTRAL/SOUTH CENTRAL KS.
INSTABILITY (1500-2000 J/KG) AND DEEP LAYER SHEAR 40-50 KT LOOK
SUPPORTIVE OF A FEW STRONG-SEVERE STORMS IN SOUTHEAST KS AS THE
FRONT MOVES THROUGH THAT AREA LATE THIS PM/EVE. HAVE INDICATED
THIS IN THE HAZARDOUS WEATHER OUTLOOK UPDATE.

JMC

PREV DISCUSSION... /ISSUED 618 AM CDT SUN SEP 30 2007/

UPDATE...

AVIATION...
FOR THE 12Z TAF SUITE.
COLD FRONTAL BOUNDARY WILL CHARGE ACROSS MOST OF KS TODAY WITH GUSTY
WINDS EXPECTED AHEAD OF AND RIGHT AFTER THE FRONTAL PASSAGE. COULD
SEE WINDS GUST TO NEAR 35 KTS NEAR KSLN AND KRSL. WIND SHIFT SHOULD
PROGRESS ACROSS THE AREA FROM 17Z NEAR KRSL AND KSLN TO 21Z IN KICT
TO AROUND 00Z/TUE IN KCNU.  LOW LEVEL MOISTURE WILL BE LIMITED FOR
TSRA DEVELOPMENT ALONG THIS BOUNDARY SO HAVE INSERTED VCTS ONLY NEAR
KCNU AROUND 22Z WHERE CONFIDENCE IS THE HIGHEST.

EXPECT CEILINGS AND VSBY ALONG THE FRONT TO STAY IN THE VFR
CATEGORY.

KETCHAM

PREV DISCUSSION... /ISSUED 214 AM CDT SUN SEP 30 2007/

DISCUSSION...

PRECIPITATION CHANCES LOOK TO BE THE MAIN PROBLEM TODAY AND THEN
AGAIN MONDAY NIGHT INTO TUESDAY.

SURFACE FRONT CURRENTLY LOCATED WELL UP INTO NEBRASKA WITH
CONVECTION FIRING AHEAD OF THE BOUNDARY AND LOSING SUPPORT IN
SOUTHWEST KANSAS.  MOISTURE PROFILE AT H8 LOOKS TO BE RATHER LIMITED
AS WE HEAD INTO SUNDAY MORNING AND EARLY AFTERNOON.  CENTRAL
SECTIONS OF THE FORECAST AREA MAY GET SKUNKED WITH ANY
PRECIPITATION. HENCE...I WILL BACK OFF ON PRECIPITATION CHANCES IN
THE CENTRAL SECTIONS.  WINDS MAY BE AN ISSUE THOUGH FOR A COUPLE OF
HOURS AFTER THE FRONT PASSES.  DECENT COLD POOL AND MOMENTUM WILL BE
PRESENT JUST BEHIND THE FRONT IN THE NORTH CENTRAL SECTIONS.
ADVISORY CRITERIA WILL BE FLIRTED WITH FOR A FEW HOURS.  LATER IN
THE DAY ACROSS THE SOUTHEAST SECTIONS...THE MOISTURE PLUME DOES POOL
A BIT BETTER IN THE AFTERNOON HOURS AHEAD OF THE SURFACE FRONT...SO
ONGOING CHANCES FOR PRECIPITATION LOOK GOOD.  FN VECTOR CONVERGENCE
ALSO ENHANCES A BIT WITH SOME ISENTROPIC LIFT AS WELL.  SO THE BEST
CHANCES FOR ANY RAIN WILL LIE ACROSS THIS SECTION OF THE FORECAST
AREA.

ON MONDAY...HIGH PRESSURE WILL FILTER INTO THE FORECAST AREA AHEAD
OF THE NEXT SYSTEM TO AFFECT THE REGION.  DECENT SOUTHERLY FLOW WILL
AID IN HELPING THE TEMPERATURES REBOUND TO ABOVE NORMAL READINGS.

ON TUESDAY THE NEXT FRONT IS EXPECTED TO BE IN NORTH CENTRAL KANSAS
EARLY TUESDAY MORNING...NEAR WICHITA AROUND NOON AND THEN OUT OF
SOUTHEAST KANSAS BY 7 PM.  THE BEST DYNAMICS AND MOISTURE PROFILES
REMAIN NORTH OF THE FORECAST AREA IN NEBRASKA. A SIMILAR SETUP WILL
OCCUR TO THE ONE THAT WILL PLAY OUT ON SUNDAY.  SO...I WILL TREND
TEMPERATURES AND CHANCES OF PRECIPITATION ACCORDINGLY.  THE ONLY
DIFFERENCE WILL BE THE WINDS...AS THE GRADIENT IS NOT QUITE AS
PACKED AND SHOULD RESULT IN SOMEWHAT LOWER WIND SPEEDS.

NO CHANGES TO THE EXTENDED WITH THIS PACKAGE.

AVIATION...
FOR 06Z TAFS...DID NOT MAKE TOO MANY CHANGES TO 00Z TAFS. IT
STILL LOOKS LIKE THE MAIN AVIATION CONCERN WILL BE THE STRONG
WINDS INITIALLY THEN THE WIND SHIFT ASSOCIATED WITH FRONTAL
PASSAGE. WINDS WILL REMAIN GUSTY OVER SOUTH CENTRAL AND ESPECIALLY
CENTRAL KS OVERNIGHT..WITH SOME GUSTS TO 35 POSSIBLE. COLD FRONT
WILL APPROACH KRSL AND KSLN AROUND OR A FEW HOURS AFTER SUNRISE
FLIPPING WINDS AROUND TO THE WEST AND NORTHWEST. ALSO FEEL THERE
WILL BE A 3-5 HOUR WINDOW BETWEEN 18Z AND 23Z WHERE WINDS OVER
CENTRAL KS MAY FLIRT WITH WIND ADVISORY CRITERIA BEHIND THE FRONT.
THERE MAYBE SOME ISOLATED CONVECTION OVER SE KS SUN AFTERNOON
ALONG AND EAST OF FRONT BUT NOT CONFIDENT ON AREAL COVERAGE.
THEREFORE JUST THREW IN SOME VCTS FOR KCNU.
