AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
608 PM CDT SUN APR 3 2011

.AVIATION...00Z TAFS KRSL/KSLN/KHUT/KICT/KCNU
STRONG COLD FRONT SHOULD BE MOVING THROUGH HUT RIGHT AROUND START
OF TAF VALID PERIOD...AND SHOULD REACH ICT AROUND 0230Z...AND CNU
AROUND 04Z. SOUTHWESTERLY WINDS AHEAD OF FRONT WILL SHIFT TO
NORTHWESTERLY BEHIND THE FRONT OWING TO STRONG PRESSURE GRADIENT
AND PRESSURE RISES. SOME GUSTS OF 35-40 KT EXPECTED THIS EVE BEHIND
FRONT MAINLY IN CENTRAL/SOUTH CENTRAL KS. THUNDERSTORMS WILL DEVELOP
ALONG THE FRONT FROM EAST CENTRAL THRU NORTHEAST KS EARLY THIS
EVE. THIS ACTIVITY SHOULD FORM INTO A LINE AND MOVE SWD ACROSS
SERN KS LATER THIS EVE. WILL INCLUDE A TEMPO TS GROUP AT CNU TO
ACCOUNT FOR THIS. NOT ENOUGH CONFIDENCE IN DEVELOPMENT FURTHER
WEST INTO S-CNTRL KS TO INCLUDE THUNDER MENTION AT HUT AND ICT BUT
WILL CONTINUE TO MONITOR. GUSTY NWRLY WINDS WILL PERSIST MONDAY
AREA WIDE.

.PREV DISCUSSION... /ISSUED 257 PM CDT SUN APR 3 2011/

DISCUSSION...

TONIGHT:
WIDELY SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP
BETWEEN 01-03Z ALONG A SURGING COLD FRONT ACROSS EAST CENTRAL
KANSAS WHERE SBCAPES OF 2500-3000 J/KG ARE PROGGED. DEEP-LAYER
SHEAR AND INSTABILITY WILL BE FAVORABLE FOR SUPERCELL
THUNDERSTORMS WITH THE BEST CHANCES MAINLY EAST-NORTHEAST OF AN
AREA OF LOW PRESSURE EXPECTED TO DEVELOP ACROSS SOUTH CENTRAL
KANSAS NEAR THE OKLAHOMA STATE LINE WHERE BOUNDARY LAYER WINDS ARE
PROGGED TO BACK EARLY THIS EVENING. THE STORMS SHOULD QUICKLY
DEVELOP INTO A SQUALL LINE WITH LARGE HAIL AND DAMAGING WINDS
BEING THE PRIMARY THREATS. STORMS SHOULD RACE EASTWARD AND CLEAR
THE AREA SHORTLY AFTER MIDNIGHT. STRONG NORTHWEST WINDS ARE
ANTICIPATED BEHIND THE COLD FRONT WHERE STRONG LOW LEVEL CAA/LARGE
3-6 HOUR PRESSURE RISES ARE PROGGED.

MCGUIRE

MONDAY-THURSDAY:
MONDAY WILL BE BLUSTERY AND COOLER WITH GUSTY NORTHWESTERLY WINDS
CONTINUING BEHIND THE COLD FRONT. WINDS COULD FLIRT WITH ADVISORY
CRITERIA IN THE MORNING BEFORE THE GRADIENT RELAXES SOME IN THE PM.
HIGHS ARE EXPECTED TO RUN ABOUT 30-35 DEGREES COOLER THAN THIS
AFTERNOONS SO IT WILL BE QUITE NOTICEABLE. FAIRLY ZONAL FLOW PATTERN
TUESDAY ALONG WITH LEE TROFFING WILL LEAD TO BREEZY TO WINDY
SOUTHWESTERLY WINDS ACROSS OUR AREA AND WARMING TEMPERATURES. UPPER
TROFFING WILL BEGIN DIGGING INTO THE WESTERN STATES WEDNESDAY INTO
THURSDAY. A WEAK COLD FRONT IS PROGGED TO DROP SOUTHWARD INTO
SOUTHERN KS/NORTHWESTERN OK BEFORE STALLING WEDNESDAY-WEDNESDAY
NIGHT. THIS FRONT WILL THEN LIFT NORTHWARD ACROSS OUR AREA THURSDAY
AS A WARM FRONT AS A SHORTAVE EJECTS OUT OF THE SOUTHWEST ACROSS
KS/OK. AS MARGINAL MOISTURE/INSTABILITY GETS DRAWN NORTHWARD INTO
OUR AREA...THERE WILL BE A CHANCE OF THUNDERSTORMS LATE WED NIGHT
INTO THURSDAY MAINLY OVER CENTRAL AND SOUTHEASTERN KS.

FRIDAY-SUNDAY:
AN UPPER LOW WILL BE MOVING THROUGH THE SOUTHWEST FRIDAY AND
SATURDAY...BEFORE LIFTING OUT ACROSS THE CENTRAL PLAINS SUNDAY INTO
SUNDAY NIGHT. THERE IS FAIRLY HIGH UNCERTAINTY ON WHERE A FRONTAL
BOUNDARY WILL BE LOCATED ACROSS THE CENTRAL PLAINS. THE ECMWF IS
FURTHER NORTH AND MAINLY NORTH OF OUR FORECAST AREA DURING THE
PERIOD...WHEREAS THE GFS HAS THE BOUNDARY OVER SOUTHERN KS/NORTHERN
OK FOR MUCH OF THE TIME...BEFORE IT LIFTS NORTHWARD SUNDAY AS THE
UPPER SYSTEM EJECTS OUT. BOTH MODELS HAVE BEEN STRUGGLING WITH
CONTINUITY IN THE EXTENDED PERIODS AS OF LATE. THERE WILL BE SOME
CHANCES FOR SHOWERS/THUNDERSTORMS DURING THIS TIME PERIOD...HOWEVER
CONFIDENCE ON PRECIPITATION TIMING/PLACEMENT IS LOW THIS FAR OUT
GIVEN THE FRONTAL BOUNDARY UNCERTAINTY THAT EXISTS. TEMPERATURES
LOOK ABOVE NORMAL.

JMC

FIRE WEATHER...
WE EXPECT EXTREME WILDFIRE DANGER/RED FLAG CONDITIONS TO PERSIST
THROUGH THIS EVENING FROM A COMBINATION OF STRONG/GUSTY
WINDS...CURED GRASSLAND...AND WELL ABOVE NORMAL TEMPERATURES. A
STRONG COLD FRONT WILL BE POSITIONED NEAR I-70 AT 6 PM CDT...WITH
THE FRONT PUSHING SOUTHWARD TO A LINE FROM KINGMAN TO WICHITA...TO
CASSODAY BY 10 PM. THE FRONT LOOKS TO BE CLEARING FAR SOUTHEAST KS
BY 2 AM. GUSTY SOUTH-SOUTHWESTERLY WINDS WILL CONTINUE SOUTH OF THE
FRONT...WITH SPEEDS OF 25 TO 35 MPH OVER S-CNTRL/SERN KS. WINDS WILL
SHIFT TO NORTHERLY BEHIND THE FRONT...WITH SPEEDS OF 20-35 MPH AND
GUSTS OF 40-45 MPH. THE HIGHER SPEEDS WILL BE IN CENTRAL/SOUTH
CENTRAL KS TONIGHT.

JMC

AVIATION...18Z TAFS KRSL/KSLN/KHUT/KICT/KCNU

STRONG SOUTH-SOUTHWEST WINDS HAVE DIMINISHED ACROSS PORTIONS OF
SOUTH CENTRAL AND CENTRAL KANSAS AS THE GRADIENT WEAKENS WITHIN
THE SFC TROUGH AXIS. FURTHER EAST-NORTHEAST SOUTHWEST WINDS
GUSTING INTO THE 40 MPH RANGE WILL CONTINUE THROUGH THE AFTERNOON
HOURS. STRONG NORTHWEST WINDS ARE EXPECTED TO DEVELOP BEHIND A
STRONG COLD FRONT THIS EVENING IMPACTING AREA TAF SITES THROUGH
AROUND 06Z BEFORE WIND SPEEDS BEGIN TO DIMINISH ONCE AGAIN. WIDELY
SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG THE SURGING
COLD FRONT THIS EVENING AND MAY IMPACT KCNU BETWEEN 05-07Z.
PROBABILITIES FURTHER WEST AND NORTH REMAIN TOO LOW FOR MENTION
IN TAFS AT THIS TIME.
