AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
327 AM CDT WED JUL 1 2015

.SHORT TERM...(TODAY THROUGH FRIDAY)
ISSUED AT 309 AM CDT WED JUL 1 2015

TODAY-TONIGHT:
MCSS OVER WESTERN MO AND SOUTHEAST NEBRASKA WILL CONTINUE TO
TRACK SOUTHEAST WITH POTENTIAL FOR TRAILING MCS TO CLIP FLINT
HILLS/SOUTHEAST KS THIS MORNING WITH A FEW RAIN SHOWERS AND/OR
THUNDERSTORMS.  ANTICIPATING THE MCS WILL LAY OUT/REINFORCE
NORTHWEST/SOUTHEAST BOUNDARY NEAR NE BORDER OF FORECAST AREA. WITH
FRONT DROPPING SOUTH...AND SOUTHWEST FLOW AHEAD OF FRONT DRYING
LOW LEVELS ...SUSPECT INITIATION WILL OCCUR AT TRIPLE POINT MID
AFTERNOON...SOMEWHERE ROUGHLY IN A KC-CNU-SGF TRIANGLE. COMBO OF
CAPE/SHEAR SUGGEST STORMS WILL BE SEVERE. THE BIG QUESTION IS HOW
FAR WEST STORMS WILL DEVELOP GIVEN INFLUX OF LOW LEVEL DRIER AIR
AND MARGINAL CONVERGENCE ON SURFACE FRONT. WESTERN EDGE MAY BE
I-35...BUT CHANCES WILL INCREASE MARKEDLY CLOSER TO EASTERN EDGE
OF FORECAST AREA. TEMPERATURES WILL ONCE AGAIN FLIRT WITH TRIPLE
DIGITS IN THE VICINITY OF AND AHEAD OF THE FRONT IN SOUTH CENTRAL
KS. STORMS CHANCES IN FAR EASTERN SECTIONS WILL LIKELY BE MAXIMIZED
THIS EVENING...BUT UNCLEAR HOW LONG MCS WILL KEEP PRECIPITATION
GOING OVERNIGHT GIVEN POTENTIAL FOR LOW LEVEL JET TO OVERRUN THE
OUTFLOW BOUNDARY LATE IN THE NIGHT.

THU-THU NIGHT:
ONE OF THE MORE CHALLENGING DAYS...WITH A LOT RIDING ON EXTENT OF
CONVECTION WED NIGHT. THINKING TRIPLE POINT COULD BE IN CENTRAL
KS...WITH EARLY AFTERNOON STORMS DEVELOPING AND DIVING SOUTH
ACROSS SOUTH CENTRAL KS IN THE LATE AFTERNOON/EVENING. WILL SHADE
POPS HIGHER ACROSS SOUTH CENTRAL KS IN THE EVENING. TEMPERATURES
ON THU WILL BE HIGHLY DEPENDENT ON CLOUDS/PRECIPITATION...BUT ODDS
FAVOR SLIGHTLY COOLER TEMPERATURES IN THE NORTH DUE TO EITHER
EXTENSIVE CLOUDS AND/OR COOLER AIR NORTH OF THE FRONT.

FRI:
CONVECTIVE CHANCES WILL LIKELY BE TIED TO TIMING OF SHORTWAVE
IN NORTHWEST FLOW. FAIR AMOUNT OF DISAGREEMENT ON TIMING...WITH
GFS FASTER/STRONGER THAN ECMWF. THERE IS ALSO SOME QUESTION ON
WHERE SURFACE MOISTURE/FRONT WOULD BE...BUT SHORTWAVE TRACK/WARMER
TEMPERATURES ALOFT WOULD FAVOR HIGHER POPS IN SOUTHEAST KS.

.LONG TERM...(SATURDAY THROUGH TUESDAY)
ISSUED AT 309 AM CDT WED JUL 1 2015

NO MAJOR CHANGES TO GOING FORECAST THIS PERIOD. OVERALL THEME IS
STILL A BREAKDOWN OF WESTERN RIDGE...AND TRANSITION INTO BROAD
ZONAL FLOW. CONFIDENCE IN DETAILS/TIMING OF THIS IS QUITE LOW...LET
ALONE MODEL QPF WHICH DRIVES INITIALIZATION GRIDS. ONCE AGAIN
TRENDED PRECIPITATION CHANCES CLOSER TO WPC GUIDANCE WHICH IS A BIT
MORE CONSERVATIVE THAN THE INITIALIZATION GRIDS. -HOWERTON

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z WEDNESDAY NIGHT)
ISSUED AT 1133 PM CDT TUE JUN 30 2015

NOCTURNAL CONVECTION ACROSS THE NORTHERN PLAINS IS EXPECTED TO DROP
SOUTHEAST ACROSS THE LOWER MISSOURI VALLEY BY WED MORNING. ANY
MESOSCALE OUTFLOW BOUNDARY IS EXPECTED TO ENHANCE OR AUGMENT THE
EFFECTIVE SURFACE FRONT MOVING SOUTHEAST INTO KANSAS BY WEDNESDAY
MORNING...PUSHING THIS BOUNDARY INTO EAST CENTRAL KANSAS BY THE END
OF THE FORECAST VALID PERIOD. SO WILL GO WITH A VCTS FOR INITIALLY
KSLN AS MID LEVEL LIFT INCREASES.  WILL ALSO GO WITH A VCTS FOR KCNU
FOR MOST OF THE AFTERNOON HOURS...AS A MID LEVEL IMPULSE PUSHES
SOUTH ALONG THE MAIN SYNOPTIC FRONT.
