AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
246 PM CDT WED APR 17 2013

.SHORT TERM...(THIS EVENING THROUGH SATURDAY)
ISSUED AT 237 PM CDT WED APR 17 2013

CONVECTION
PRE AND POST FRONTAL STRONG TO SEVERE CONVECTION WITH HEAVY
RAINFALL EXPECTED THRU THIS EVENING ACROSS PORTIONS OF CENTRAL
AND SOUTHEAST KANSAS. THE HIGHER IMPACT SEVERE IS STILL EXPECTED
ALONG THE SURFACE FRONT ACROSS SOUTHEAST KANSAS WITH DAMAGING
WINDS...LARGE HAIL AND A TORNADO POSSIBLE DURING THE EARLY
EVENING. HOWEVER ELEVATED INSTABILITY OVER THE COLD AIR WILL
STILL SUPPORT SOME HAILERS FURTHER WEST ACROSS PORTIONS OF
CENTRAL KANSAS. CONVECTION WILL TEND TO REDEVELOP AND
REPEAT/TRAIN OVER SOME AREAS WHICH PORTENDS TO HEAVY RAINFALL
AND FLOOD POTENTIAL. THE LONGER DURATION APPEARS TO BE OVER
SOUTHEAST KANSAS INTO THE OVERNIGHT HOURS...SO WILL ISSUE A
FLOOD WATCH FOR THESE AREAS.

WINTRY PRECIP
NEXT CHALLENGE IS WITH THE SURGE OF COLD AIR AND POST FRONTAL
PRECIPITATION LATER TONIGHT INTO THURSDAY MORNING. WHILE NOT
QUITE AS IMPRESSIVE AS LAST WEEK...IT DOES LOOK LIKE WE WILL GET
A TRANSIENT AREA OF A LIGHT WINTRY MIX ACROSS CENTRAL KANSAS WITH
THE NAM PREFERRED IN THIS REGARD. DEPENDING ON CHANGEOVER AND
MOISTURE DEPTH/LIFT...THIS COULD BE SOME LIGHT FREEZING RAIN
AND/OR SNOW OR FREEZING DRIZZLE...THOUGH FOR NOW ANY ACCUMS ARE
STILL EXPECTED TO BE LIGHT. THAT SAID...THIS IN COMBO WITH STRONG
NORTH WINDS NEAR ADVISORY CRITERIA INTO EARLY THURSDAY
MORNING...PLAN TO ISSUE A WINTER WEATHER ADVISORY FOR A PORTION
OF CENTRAL KANSAS. SOME LIGHT MIXED PRECIP COULD BE OBSERVED AS
FAR EAST AS THE FLINT HILLS INTO LATER THURSDAY MORNING...HOWEVER
TEMPERATURES SHOULD RECOVER TO A BIT ABOVE FREEZING BY THEN SO OF
LITTLE CONSEQUENCE EXPECTED.

FREEZE/RECORD COLD THURSDAY NIGHT
THE THIRD CONCERN IS WITH RECORD COLD AND WIDESPREAD FREEZE
EXPECTED. THIS LOOKS TO BE A PURE COLD ADVECTION TYPE WITH
MINS INTO THE MID TO UPPER 20S IN MOST LOCALES DESPITE A BIT
OF NOCTURNAL/EARLY MORNING WIND. CONSIDERED A HEADLINE/WATCH
FOR THIS...HOWEVER WITH THE OTHER MORE IMMINENT IMPACTS IN
THE SHORTER TERM HAVE DECIDED TO HOLD OFF AND MAINTAIN MENTION
IN THE HAZARDOUS WEATHER OUTLOOK. HOWEVER IF CONFIDENCE
REMAINS HIGH...A FREEZE WARNING WILL LIKELY BE FORTHCOMING IN
THE NEXT FORECAST CYCLE OR TWO.

SOME MODERATION AND RETURN TO DRY WEATHER IS EXPECTED FOR
FRIDAY AND SATURDAY AND MADE ONLY A SLIGHT UPTWEAK TO THE
TEMPERATURES CLOSER TO SEASONAL CLIMO BY SATURDAY.

DARMOFAL

.LONG TERM...(SUNDAY THROUGH WEDNESDAY)
ISSUED AT 237 PM CDT WED APR 17 2013

SINCE MAIN FOCUS HAS BEEN ON SHORT TERM DO NOT PLAN ON ANY
SIGNIFICANT CHANGES TO THE OUTER PERIODS WITH THIS FORECAST.
MEDIUM RANGE STILL SUPPORTS ANOTHER COOL DOWN EARLY NEXT
WEEK WITH SOME PRECIP CHANCES AHEAD OF AND JUST BEHIND THE
FRONTAL PASSAGE FROM SUNDAY INTO TUESDAY.

DARMOFAL

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z THURSDAY AFTERNOON)
ISSUED AT 118 PM CDT WED APR 17 2013

THE MAIN AVIATION FORECAST CONCERN ARE THE LIFR/IFR CONDITIONS
WEST OF THE WARM FRONT WITH SCATTERED THUNDERSTORMS IMPACTING ALL SITES.

LIFR/IFR CEILINGS ARE PRESENT ACROSS MUCH OF THE AREA AS SHALLOW
COLD AIR REMAINS ENTRENCHED OVER THE AREA. AS THE WARM FRONT LIFTS
NORTHWEST OVER SOUTHEASTERN KANSAS CEILINGS HAVE LIFTED TO
MVFR. THE FRONT WILL STALL AND BECOME A COLD FRONT AS THE SYSTEM
MOVES EASTWARD TONIGHT. THUNDERSTORMS WILL BE POSSIBLE OFF AND ON
THROUGHOUT MUCH OF THE FORECAST WITH SEVERE THUNDERSTORMS POSSIBLE
ACROSS SOUTHEASTERN SECTIONS...IMPACTING KCNU THIS EVENING AND
OVERNIGHT.

THE PRESSURE GRADIENT WILL INCREASE AS THE FRONT BEGINS TO MOVE
EASTWARD. NORTHWESTERLY WINDS WILL INCREASE TO 30 MPH WITH GUSTS
OVER 35MPH. THIS WILL IMPACT ALL SITES EXCEPT KCNU...BUT KRSL/KSLN
WILL HAVE THE STRONGEST WINDS.

THE SYSTEM WILL EXIT TOWARD THE END OF THE TAF PERIOD WITH
CEILINGS IMPROVING TO MVFR/VFR.

.FIRE WEATHER...
ISSUED AT 237 PM CDT WED APR 17 2013

GRASSLAND FIRE DANGER WILL REMAIN LOW DUE TO WIDESPREAD
PRECIPITATION TONIGHT INTO EARLY THURSDAY. A DRYING PROCESS

FOR RAIN SUNDAY INTO EARLY NEXT WEEK.
