Verified. The Iowa Environmental Mesonet's Cow matched 2 storm reports to this severe thunderstorm warning; the first came 38 minutes after it went out.

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 Wichita, KS wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 22, 11:25 PM CDT, 1 hour 48 minutes earlier.

WEAK SHORTWAVE WAS MOVING EWD OVER CENTRAL KS LATE THIS EVE. THIS
FEATURE WILL CONTINUE TRACKING E-NEWD AND WILL MOVE OUT OF NERN KS
THURS AM. SCT TS EXPECTED TO CONTINUE OVER CNTRL INTO E-CNTRL KS
OVERNIGHT ON THE NORTH EDGE OF THE MID-LEVEL BAROCLINIC ZONE.
VARIABLE GUSTY WINDS WILL BE ASSOCIATED WITH THE CONVECTION. FOR

UPDATE...
HAVE INCREASED/ADDED POPS ACROSS THE FORECAST AREA FOR TONIGHT.
THIS IS IN PART DUE TO LATEST RADAR TRENDS. IN ADDITION...THE
RUC40 AND 00Z NAM-WRF CONTINUE TO SHOW A VERY TIGHT ISENTROPIC
PRESSURE GRADIENT (310K) FROM W TO E ACROSS OUR AREA FOR MUCH OF
NIGHT WITH DEVELOPING 35 KT LOW-LEVEL JET TRANSPORTING ELEVATED
INSTABILITY INTO THIS BAROCLINIC ZONE. A FEW STRONG TO MARGINALLY
SEVERE STORMS REMAIN POSSIBLE OVERNIGHT GIVEN THE INSTABILITY AND
30KT OF EFFECTIVE SHEAR.

INSTABILITY/ISENTROPIC LIFT SHOULD MAXIMIZE. GFS SEEMS TO BE NOT
PICKING UP ON CURRENT TS ACTIVITY. WILL UTILIZE VCTS IN CNTRL KS
SITES DUE TO ANTICIPATED ISOLD-SCT COVERAGE AND ADJUST AS NEEDED.
CONVECTION SHOULD BE PUSHING NEWD OUT OF CNTRL KS THURS AM. WILL
INCLUDE A TEMPO MVFR BR GROUP AT HUT EARLY THURS AM MAINLY DUE TO
LOCAL RADIATION EFFECTS.

JMC

PREV DISCUSSION... /ISSUED 328 PM CDT WED APR 22 2009/

DISCUSSION...

THE MAIN CONCERN WITH THIS FORECAST PACKAGE WILL BE THE POTENTIAL
FOR ELEVATED STRONG TO SEVERE CONVECTION THIS EVENING IN CENTRAL
KANSAS. THE NEXT CONCERN IS THE TIMING OF SHORTWAVES MOVING THROUGH
THE AREA THIS WEEKEND.

TONIGHT:
LATEST WATER VAPOR LOOP WAS SHOWING A SUBTLE POTENTIAL VORTICITY
ANOMALY MOVING THROUGH NORTHERN COLORADO AND SOUTHERN WYOMING. IN
RESPONSE TO THIS WAVE...WE ARE SEEING SOME ELEVATED CONVECTION
DEVELOPING OVER NORTHEAST COLORADO. LATEST VISIBLE IMAGERY WAS ALSO
SHOWING QUITE A BIT OF ACCAS NEAR A BAROCLINIC ZONE DEVELOPING OVER
SOUTHWEST KANSAS WITH EVEN A THUNDERSTORM DEVELOPING JUST WEST OF
PRATT. MODELS SEEMED TO DO A FAIRLY GOOD JOB ON THE MODEL
INITIALIZATIONS REGARDING THE MOISTURE PROFILES OVER DODGE CITY THIS
MORNING. EVEN THOUGH SURFACE DEWPOINTS ARE IN THE 45 TO 50 DEGREE
RANGE...WE HAVE QUITE A BIT OF EVELATED CAPE (1000-1500J/KG) MAINLY
ABOVE 700MB. HAVILAND SHEAR PROFILE IS ALSO SHOWING DECENT 700-500MB
SHEAR IN PLACE AROUND 30KTS. AS A RESULT...I WOULD NOT BE SURPRISED
TO SEE A FEW STRONG TO SEVERE STORMS THIS EVENING MAINLY IN CENTRAL
KANSAS...ESPECIALLY IF THE POTENTIAL VORTICITY ANOMALY STRENGTHENS
AND THE LOW LEVEL JET ENHANCES AS THE ANOMALY APPROACHES. OVERNIGHT
THINGS SHOULD BEGIN TO CLEAR OUT AS THE SHORTWAVE MOVES OUT OF THE
AREA.

THURSDAY-SATURDAY:
LATEST WATER VAPOR LOOP WAS SHOWING THE NEXT SHORTWAVE OVER THE
PACIFIC NORTHWEST. THIS FEATURE IS PROGGED TO AFFECT THE REGION
THIS WEEKEND. AS THIS FEATURE DIVES INTO THE ROCKIES...THIS WILL
INDUCE STRONGER RETURN FLOW WHICH WILL HELP FEED HIGHER DEWPOINTS
INTO THE REGION. IN ADDITION...THE LEE SIDE TROF WILL STRENGTHEN
OVER THE ROCKIES AND CAUSE THE WIND SPEEDS TO REALLY INCREASE ON
FRIDAY AND SATURDAY. AS THE PREVIOUS FORECASTER MENTIONED...WE WOULD
NOT BE SURPRISED TO WIND ADVISORY CRITERIA BEING REACHED. WE WENT
AHEAD AND BACKED OFF ON POPS MAINLY ACROSS SOUTH CENTRAL AND
SOUTHEAST KANSAS ON SATURDAY DUE TO A DECENT MID LEVEL CAP IN PLACE.

SUNDAY-WEDNESDAY:
THE MODELS ARE STILL SHOWING SOME DISCREPANCIES ON THE TIMING OF THE
NEXT WAVE MOVING FROM THE ROCKIES INTO THE PLAINS. THE ECMWF IS
STILL ABOUT 12 HOURS SLOWER THAN THE GFS IN MOVING THIS WAVE INTO
THE NORTHERN PLAINS. WE ARE FAVORING THIS SOLUTION FOR NOW BASED ON
MODEL CONSISTENCY. AS A RESULT...WE ARE THINKING THAT THE BEST
SEVERE CHANCES MAY STILL BE THE LATE SATURDAY NIGHT/SUNDAY TIMEFRAME
WITH THE MORE SIGNIFICANT WAVE MOVING INTO THE NORTHERN PLAINS. THIS
WILL PUSH THE FRONT INTO SOUTHERN KANSAS BY MONDAY MORNING. THE NEXT
PROBLEM IS THE MODELS ARE STALLING OUT THIS BOUNDARY ACROSS SOUTHERN
KANSAS ON MONDAY AND TUESDAY WHICH WILL SET THE STAGE FOR THE NEXT
WAVE MOVING THROUGH THE ROCKIES INTO THE PLAINS ON MONDAY. THIS
TIMEFRAME MAY NEED TO BE WATCHED FOR POSSIBLE FLOODING. WE WILL
CONTINUE TO MONITOR FOR NOW.

859 PM CDT WED APR 22 2009

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF CENTRAL KANSAS...
SOUTH CENTRAL KANSAS AND SOUTHEAST KANSAS.

.DAY ONE...TONIGHT

A FEW STRONG TO SEVERE THUNDERSTORMS WILL BE POSSIBLE TONIGHT
MAINLY ACROSS CENTRAL AND PART OF SOUTH CENTRAL KANSAS. THE MAIN
THREATS WILL BE PENNY TO QUARTER SIZE HAIL AND 50 TO 60 MPH WIND
GUSTS.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

HIGH GRASSLAND FIRE DANGER WILL ENCOMPASS MUCH OF THE AREA BY
THURSDAY AFTERNOON.

STRONG SOUTH WINDS ARE EXPECTED ON FRIDAY AND SATURDAY WHICH WILL
CAUSE THE GRASSLAND FIRE DANGER INDEX TO BE IN THE HIGH TO VERY
HIGH CATEGORY.

CONFIDENCE IS INCREASING THAT SCATTERED STRONG TO SEVERE
THUNDERSTORMS WILL OCCUR ACROSS THE AREA SATURDAY NIGHT THROUGH
TUESDAY...AS A COLD FRONT APPROACHES FROM THE NORTHWEST AND
INTERACTS WITH A MOIST AND UNSTABLE AIRMASS ACROSS THE PLAINS. THIS
FRONT MAY BEGIN TO STALL OUT ACROSS THE AREA ON SUNDAY NIGHT AND
MONDAY WHICH MAY ALSO INCREASE THE RISK FOR LOCALIZED FLOODING.
HOWEVER...MUCH UNCERTAINTY EXISTS SURROUNDING THE TIMING OF THE
COLD
FRONT AND VARIOUS UPPER LEVEL DISTURBANCES. STAY TUNED FOR LATER
FORECASTS AND OUTLOOKS.
