Severe Thunderstorm Warning 163, NWS Wichita, KS

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
640 PM CDT WED JUN 18 2014

...UPDATED FOR 00Z AVIATION DISCUSSION...

.SYNOPSIS...
ISSUED AT 317 PM CDT WED JUN 18 2014

UPPER LEVEL DATA ANALYSIS ENDING AT 19Z SHOWS A CLOSED LOW AT 500 MB
OVER SOUTHWEST MONTANA.  SOUTHWESTERLY FLOW CONTINUES ACROSS THE
REGION AS A RESULT OF THIS LOW.  THIS LOW CONTINUES TO MOVE SLOWLY
NORTHEASTWARD.

SATELLITE DATA LOOP ENDING AT 1915Z SHOWS AN AREA OF ACCAS THAT HAS
EXTENDED FROM THE TEXAS PANHANDLE INTO CENTRAL KANSAS.  THIS HAS
BEEN PRESENT FOR SEVERAL HOURS AND OUTLINES THE AREA OF FAVORED
CONVECTIVE INITIATION THIS AFTERNOON.

AT THE SURFACE...LOW PRESSURE WAS CENTERED OVER SOUTH CENTRAL SOUTH
DAKOTA.  A COLD FRONT EXTENDS FROM THIS LOW DOWN TO NEAR
KODX-KTQK-KLIC.  A DRYLINE EXTENDS FROM JUST WEST OF KGCK...SOUTH TO
JUST WEST OF KLBL INTO THE OKLAHOMA AND TEXAS PANHANDLE.

CONVECTIVE DEVELOPMENT HAS INITIATED ACROSS WEST TEXAS ALONG THE
AFOREMENTIONED FAVORED AREA.  THIS IS PRETTY CLOSE TO WHERE THE 17Z HRRR
RUN HAS SHOWN IT.

MAIN FORECAST CHALLENGE REMAINS CONVECTION.

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 317 PM CDT WED JUN 18 2014

THE TREND OF THE HRRR RUNS FOR CONVECTION THIS EVENING CONTINUES TO
SHOW MORE RAINFALL FOR A GOOD PORTION OF THE FORECAST AREA.  THIS IS
A DIVERGENCE TO THE OTHER NWP...BUT GIVEN ITS ACCURACY AND
PERFORMANCE...WILL MAKE ADJUSTMENTS TO THE FORECAST FOR
TONIGHT.

AS FAR AS SEVERE GOES...SHEAR/BUOYANCY COMBINATIONS SUGGEST
POTENTIAL FOR ORGANIZED CONVECTION ACROSS WESTERN KANSAS.  AS ONE
MOVES EAST...DEEP LAYER SHEAR FALLS BELOW 20 KNOTS BEFORE YOU REACH
INTERSTATE 135.  THIS SHOULD PRECLUDE SEVERE CONVECTION EAST OF
INTERSTATE 135.

THE AFOREMENTIONED COLD FRONT WILL MOVE SOUTH INTO THE FORECAST AREA
THURSDAY.  THIS WILL BE THE FOCUS FOR CONVECTION THURSDAY
AFTERNOON.  SHEAR/BUOYANCY COMBINATIONS AGAIN LOOK
FAVORABLE...THOUGH ON THE LOWER END OF THAT FAVORABLY FOR
ORGANIZED CONVECTION FOR SEVERE WEATHER.  THIS FAVORABLY WILL
REMAIN IN THE VICINITY OF THE FRONT.  IF STORMS STRAY FROM OR
ORGANIZE AND MOVE AWAY FROM THE FRONT AND OUTRUN THE FAVORABLE DEEP
LAYER SHEAR...THEY SHOULD WEAKEN.

COOK

.LONG TERM...(FRIDAY THROUGH WEDNESDAY)
ISSUED AT 317 PM CDT WED JUN 18 2014

INTO THE WEEKEND...THE QUASI-STATIONARY FRONT REMAINS AROUND THE
REGION.  NWP IS IN SOME DISARRAY WITH THE POSITION OF THE
BOUNDARY...AFFECTED BY OUTFLOWS AND COLD POOLS. CONFIDENCE IN
CONVECTION LOCATION IS QUITE LOW.  THAT SAID...CONFIDENCE IS HIGH
THAT THE FRONT REMAINS IN CLOSE ENOUGH PROXIMITY TO THE FORECAST
AREA INTO THE MIDDLE OF NEXT WEEK...WITH FAVORABLE CONDITIONS FOR
LATE AFTERNOON AND NOCTURNAL CONVECTION.  SEVERE CONDITIONS WILL BE
FAVORABLE NEAR THE STALLED FRONT...WHICH SHEAR/BUOYANCY COMBINATIONS
ARE MOST FAVORABLE.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z THURSDAY EVENING)
ISSUED AT 640 PM CDT WED JUN 18 2014

THE MAIN AVIATION FORECAST CONCERN IS THE CHANCES FOR STORMS
TONIGHT AND THEN THROUGH THE REMAINDER OF THE FORECAST.
THUNDERSTORMS TONIGHT MAY IMPACT KRSL WITHIN THE NEXT FEW HOURS AS
STORMS DEVELOP AHEAD OF THE COLD FRONT OVER WESTERN KANSAS AND
MOVE NORTHEAST INTO THE KRSL TERMINAL. CONFIDENCE IN CONVECTION
AFTER THIS MAIN ACTIVITY TONIGHT IS LOW. CANNOT RULE OUT
CONVECTION OVERNIGHT AND DURING THE DAY THURSDAY...BUT CONFIDENCE
IN LOCATION AND TIMING IS LOW AND HAVE LEFT OUT OF THE TAFS AT
THIS TIME.

THE COLD FRONT WILL PUSH SOUTHEAST TOWARDS THE AREA...BUT CURRENT
GUIDANCE STALLS THE FRONT BETWEEN KRSL AND KSLN DURING THE DAYTIME
THURSDAY. THIS LOCATION IS CONTINGENT ON HOW OVERNIGHT CONVECTION
BEHAVES. AN OUTFLOW BOUNDARY COULD PUSH THE FRONT FURTHER SOUTH
THAN THE CURRENT GUIDANCE INDICATES.

LOWER CEILINGS IN THE MVFR RANGE COULD BE POSSIBLE ACROSS
KRSL/KSLN AS THE FRONT NEARS THOSE LOCATIONS THURSDAY AFTERNOON.
