AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
1140 PM CDT SAT APR 28 2012

.AVIATION...06Z TAFS KRSL/KSLN/KHUT/KICT/KCNU

MVFR CIGS ALREADY PRESENT OVER SOUTHEAST KANSAS AT THIS TIME...AND
EXPECT THIS CLOUD DECK TO CONTINUE OVERNIGHT FOR KCNU. EXPECT THIS
LOWER CLOUD DECK TO INCREASE IN AREAL COVERAGE ACROSS THE REST OF
THE FORECAST AREA AFTER 09Z/SUN...AS WARM ADVECTION AND MOISTURE
ADVECTION INCREASES ACROSS MOST OF SOUTH CENTRAL KS INTO CENTRAL
KS.  AS THIS LOW LEVEL MOISTURE INCREASES...EXPECT CEILINGS TO DROP
TO MVFR WITH THE CHANCES OF SHOWERS AND TSRA INCREASING AS WELL.
COULD ACTUALLY SEE SOME SCATTERED IFR CLOUDS BY AROUND 12-14Z/SUN AS
TSRA/SHRA BECOME MORE WIDESPREAD. THINK LOWER IFR CEILINGS WILL BE
CONFINED IN CLOSE TO THE STRONGEST STORMS...SO WILL INCLUDE A TEMPO
GROUP FOR THIS CHANCE NEAR KICT/KHUT/KSLN AND KCNU.

WILL SEE A DIMINISHING TREND IN THE SHOWER ACTIVITY FOR MOST
LOCATIONS FOR THE LATE AFTERNOON HOURS ON SUN...BUT THE MVFR CIGS
WILL CONTINUE.  THE ONLY EXCEPTION WILL BE SE KS NEAR THE KCNU TAF
SITE...WHERE SHRA/TSRA ACTIVITY MAY CONTINUE AS THIS AREA AS IT
REMAINS CLOSE TO THE STATIONARY BOUNDARY EXPECTED TO BE LOCATED OVER
SOUTHEAST KS.

COULD SEE ANOTHER ROUND OF SHRA/VCTS MOVE INTO THE AREA FROM WRN
KS...AFTER 05Z/MON. SO WILL INCLUDE THIS IN THE KHUT TAF FOR
NOW...WITH THIS CONVECTION EXPECTED TO OVERSPREAD THE REST OF THE
AREA AFTER THIS TAF TIME FRAME...AFTER 06Z/MON.

UPDATE...

LOW LEVEL MOISTURE TRANSPORT IS GRADUALLY INCREASING ALONG THE
THETA-E GRADIENT CURRENTLY LOCATED OVER THE FLINT HILLS AT THIS
TIME. THIS INCREASED MOISTURE TRANSPORT HAS LED TO A LINE OF SHOWERS
DEVELOPING FROM NEAR KEMP TO NEAR KWLD.  MUCAPE IS INCREASING TO
AROUND 600 J/KG SO EXPECT A FEW RUMBLES OF THUNDER AS THIS LINE OF
SHOWERS CONTINUES TO LIFT TO THE NORTH-NORTHWEST...AS MOISTURE
TRANSPORT CONTINUES TO PUSH THE THETA-E GRADIENT BACK TO THE
NORTHWEST AS THE OVERNIGHT CONTINUES.  WILL SEE A GRADUAL INCREASE
IN THE SHOWER/THUNDERSTORM ACTIVITY LATE TONIGHT /AFTER 09Z/ AS A
SHORTWAVE CURRENTLY IN NRN NM LIFTS NORTHEAST INTO CEN KS BY AROUND
12Z/SUN.  AS THIS S/WV LIFTS NORTHEAST...EXPECT THE SHOWERS/STORMS
TO BECOME MORE WIDESPREAD ALONG THE MAIN THETA-E GRADIENT EXPECTED
TO BE LOCATED ALONG A LINE FROM KP28 TO JUST NORTH OF KEMP.  MUCAPE
VALUES INCREASE TO AROUND 1200-1500 J/KG LATE TONIGHT...WITH 0-6KM
BULK SHEAR VALUES AROUND 30-35 KTS...SO A FEW STRONG STORMS MAY
DEVELOP BETWEEN 09-13Z/SUN...WITH SMALL HAIL THE MAIN THREAT.

WILL INCREASE POPS SOME ALONG THE KP28 TO KEMP AXIS...WITH THIS IN
MIND. THE REST OF THE FORECAST LOOKS OKAY WITH SOME MINOR CHANGES TO
QPF.

DISCUSSION...

TONIGHT-SUN:
RATHER MESSY START TO THE FIRST FEW DAYS OF FORECAST. CRUX OF
FORECAST IS LOCATION OF SURFACE BOUNDARY/MOISTURE AND TIMING OF
RIPPLES IN UPPER FLOW WHICH SHOULD SIGNIFICANTLY MODULATE
PRECIPITATION CHANCES GIVEN THE LACK OF STRONG ISENTROPIC LIFT IN
THE VICINITY OF BOUNDARY. BASED ON WATER VAPOR LOOP...NEXT WAVE
IS NEAR FOUR CORNERS AT MIDDAY. EXTRAPOLATION WOULD PUT IT
CROSSING FORECAST AREA WELL AFTER MIDNIGHT TONIGHT. THIS WILL
PROBABLY BRING THE BEST CHANCE FOR PRECIPITATION...GIVEN WAVE...
BOUNDARY AND CLIMATOLOGICALLY FAVORED TIME OF DAY. WITH AROUND
1000 J/KILOGRAM MUCAPE AND MARGINALLY FAVORABLE MID LEVEL WIND
SHEAR...COULD HAVE A FEW STRONG STORMS/HAIL THREAT...MAINLY EAST
OF I-35. COULD ALSO SEE AN ISOLATED STORM OR TWO IN EXTREME
SOUTHEAST KS NEAR SURFACE BOUNDARY THIS AFTERNOON...AND POSSIBLY
DURING THE EVENING IN 850MB THETA-E ADVECTION. PRECIPITATION SHOULD
BE ON THE WANE AFTER SUNRISE SUNDAY IN WAKE OF DEPARTING RIPPLE.
BELIEVE PRECIPITATION COULD REMAIN SUPPRESSED WELL INTO THE
AFTERNOON. ISOLATED-SCATTERED STORMS MIGHT DEVELOP LATE SUN
AFTERNOON WITH ENOUGH CLEARING AND HEATING TO BREAK CAP...BUT
UNCERTAINTY OF BOUNDARY LOCATION OR AMOUNT OF CLEARING MAKES THIS
A TOUGH CALL.

SUN NIGHT-MON:
ANOTHER RIPPLE AND A BIT BETTER ISENTROPIC LIFT SUGGEST
PRECIPITATION MAY BE A BIT MORE PLENTIFUL ON SUN NIGHT AND WANE
DURING THE DAY ON MON. AGAIN CONSIDERABLE UNCERTAINTY ON HOW THIS
WILL PLAY OUT...GIVEN TIMING ISSUES WITH WAVE AND LOCATION OF
SURFACE BOUNDARY.

TUE-FRI:
LOW CONFIDENCE FORECAST WITH CONSIDERABLE DIFFERENCES BETWEEN
GFS/ECMWF. GFS HAS SHOW QUITE A BIT MORE RUN TO RUN CONTINUITY
THAN ECMWF AND WILL LEAN THAT WAY WITH FORECAST. MAIN ISSUE IS
WAVES MOVING THROUGH FAIRLY RAPID ZONAL FLOW AND PROBLEMS WITH
AMOUNT CENTRAL US RIDGING. FAIRLY CERTAIN THAT THERE WILL NOT BE
CONTINUOUS RAIN THROUGHOUT THIS PERIOD...BUT TIMING THE WET/DRY
PERIODS/LOCATIONS IS PROBLEMATIC. MADE SOME TWEAKS TO
INTIALIZATION GRIDS TO REFLECT MORE OF GFS TIMING/LOCATION. AT
THIS TIME...THE BEST CHANCE OF RAIN DURING THIS PERIOD APPEARS TO
BE WED NIGHT...AND DRIEST ON FRI/SAT WITH SURFACE RIDGE OVER THE
AREA. HOWEVER AM FAIRLY CONFIDENT THAT THIS TIMING WILL CHANGE
OVER THE NEXT FEW DAYS. -HOWERTON
