AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
1236 PM CDT WED MAY 27 2015

...UPDATED FOR 18Z AVIATION DISCUSSION...

.SHORT TERM...(TODAY THROUGH FRIDAY)
ISSUED AT 334 AM CDT WED MAY 27 2015

SUMMARY: ACTIVE PATTERN IS EXPECTED TO CONTINUE THROUGH FRIDAY
NIGHT/EARLY SATURDAY...WITH UP TO 3-4 MORE ROUNDS OF THUNDERSTORMS
POSSIBLE ACROSS THE KANSAS REGION. DRIER WEATHER SHOULD FINALLY
ENTER THE FORECAST BY THE WEEKEND...EXTENDING THROUGH AT LEAST MID
NEXT WEEK.

CANNOT RULE OUT A STRAY STORM EARLY THIS MORNING OVER EXTREME SE
KS WITHIN ZONE OF 900-800 MOISTURE TRANSPORT...BUT SUSPECT BRUNT
OF THIS ACTIVITY WILL REMAIN SOUTH/SOUTHEAST OF THE BORDER.
OTHERWISE...QUASI-STATIONARY BOUNDARY CURRENTLY OVER NORTHERN OK
IS EXPECTED TO MIX SLOWLY NORTH TODAY...BECOMING FAIRLY DIFFUSE AS
THE DAY PROGRESSES. HOWEVER...THERE MAY BE JUST ENOUGH LOCALIZED
CONVERGENCE AMIDST AN INCREASING MOIST/UNSTABLE AND WEAKLY CAPPED
BOUNDARY LAYER TO INITIATE ISOLATED THUNDERSTORMS BY MID-LATE
AFTERNOON...ESPECIALLY OVER SOUTHERN KS. DESPITE MODEST (AT BEST)
DEEP LAYER SHEAR...POTENTIAL FOR STRONG INSTABILITY WILL FAVOR
STRONG/SEVERE ACTIVITY WITH ANYTHING THAT CAN MANAGE TO DEVELOP.

HIGHER CONFIDENCE FORECAST IS SCATTERED CONVECTION INITIATING
DURING THE MID-LATE AFTERNOON OVER WEST/SOUTHWEST KS ALONG A
DIFFUSE DRYLINE...POSSIBLY SPREADING EAST INTO CENTRAL AND SOUTH-
CENTRAL KS DURING THE EVENING. WHILE GREATEST SEVERE POTENTIAL
WILL LIKELY REMAIN JUST WEST OF THE FORECAST AREA...SEVERE CHANCES
COULD DRIBBLE INTO AREAS GENERALLY WEST OF I-135.
ADDITIONALLY...LOCALLY VERY HEAVY RAINFALL WILL ACCOMPANY ALL
ACTIVITY THAT CAN MANAGE TO DEVELOP TODAY-TONIGHT.

WHILE SPECIFICS REGARDING EXACT LOCATION/TIMING/COVERAGE OF
THUNDERSTORMS IS DIFFICULT TO PINPOINT AT THIS TIME...OVERALL
PATTERN OF MID/UPPER WAVES APPROACHING FROM THE WEST/SOUTHWEST
AMIDST A MOIST/UNSTABLE AIRMASS FAVORS CONTINUED OFF-AND-ON
THUNDERSTORM CHANCES THURSDAY-THURSDAY NIGHT. BEST GUESS AT THIS
POINT IS MORNING CONVECTION POSSIBLY AFFECTING THE REGION...WITH
ANOTHER ROUND THURSDAY LATE AFTERNOON THROUGH NIGHT. AS HAS BEEN
THE CASE...WIDESPREAD ORGANIZED SEVERE WEATHER IS NOT ANTICIPATED
DUE TO WEAK/MODEST DEEP LAYER SHEAR...ALTHOUGH DEGREE OF
INSTABILITY COULD FAVOR A HANDFUL OF STRONG/SEVERE STORMS...ALONG
WITH LOCALLY VERY HEAVY RAIN.

FINAL AND POSSIBLY MORE ORGANIZED/WIDESPREAD ROUND OF
SHOWERS/THUNDERSTORMS IS EXPECTED FRIDAY-FRIDAY NIGHT...AS A
STRONG COLD FRONT APPROACHES FROM THE NORTHWEST...AMIDST
INCREASING UPPER SUPPORT APPROACHING FROM THE SOUTHWEST. MODEL
CONSENSUS HAS TIGHTENED UP A BIT REGARDING THIS PERIOD...SO FAIRLY
CONFIDENT THAT PRECIPITATION CHANCES WILL SHUT DOWN BY EARLY
SATURDAY.

KLEINSASSER

.LONG TERM...(SATURDAY THROUGH TUESDAY)
ISSUED AT 334 AM CDT WED MAY 27 2015

MEDIUM RANGE GUIDANCE AND ASSOCIATED ENSEMBLES SUPPORT A MUCH
NEEDED DRYING TREND REGIONWIDE BY SATURDAY...PERSISTING THROUGH AT
LEAST MID NEXT WEEK...AS UPPER RIDGING BUILDS ACROSS MID-AMERICA.
ADDITIONALLY...INCREASING THICKNESS VALUES WILL SUPPORT HIGH
TEMPERATURES CLIMBING INTO THE 80S BY NEXT WEEK. ABUNDANT
EVAPOTRANSPIRATION WILL LIKELY LEAD TO FAIRLY HUMID CONDITIONS.
UPPER PATTERN DISPLAYED BY GFS/ECMWF NEXT WEEK CERTAINLY DOES LOOK
MORE SUMMER-LIKE.
