AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
706 PM CDT WED JUL 1 2015

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

.SYNOPSIS...
ISSUED AT 357 PM CDT WED JUL 1 2015

THIS AFTERNOON A WEAK SURFACE TROUGH EXTENDS FROM A TRIPLE POINT
POSITIONED VERY CLOSE TO KMHK...THROUGH CENTRAL KS BETWEEN KSLN &
K9K7...TO THE KS/OK BORDER SOUTH OF KDDC. SE OF THE TROUGH...VERY
MOIST AIR IS ENTRENCHED PRIMARILY SE OF THE TURNPIKE AS EVIDENCED
BY SURFACE DEW POINTS IN THE LOWER 70S. SCATTERED SHOWERS ARE
MOVING SE ACROSS SOUTHEAST KS WHERE TEMPERATURES IN THE LOWER-MID
80S RESIDE WHILE ACROSS CENTRAL & SOUTH-CENTRAL KS 90S DOMINATE.

&&

.SHORT TERM...(THIS EVENING THROUGH SATURDAY)
ISSUED AT 357 PM CDT WED JUL 1 2015

FORECAST HIGHLIGHT:
SEVERE THUNDERSTORMS STILL EXPECTED ACROSS SOUTHEAST KS FROM LATE
THIS AFTERNOON UNTIL LATE THIS EVENING.

TONIGHT:
AS EXPECTED...THE AIRMASS ACROSS SOUTHEAST KS IS DESTABILIZING WITH
MLCAPES FROM 2500-3500 J/KG COVERING MOST OF THE AREA WITH THE
GREATEST INSTABILITIES ALONG & WEST OF THE MO BORDER. MLCAPES HAVE
INCREASED ~1500 J/KG SINCE NOON. WITH A STRENGTHENING MID-LEVEL
SHORTWAVE SCOOTING SE ACROSS EASTERN KS/WESTERN MO 6-KM BULK SHEAR
FROM 35-40KTS WILL COVER THESE SAME AREAS. SUCH INSTABILITY & DEEP
LAYER SHEAR WOULD FAVOR SUPERCELLS FROM LATE THIS AFTERNOON UNTIL
MID-EVENING. LARGE HAIL...PERHAPS GOLFBALL-SIZED & WINDS ~70 MPH
BOTH REMAIN THREATS...HOWEVER IT APPEARS THE BOUNDARY LAYER FLOW
WILL MAINTAIN A DUE SOUTH COMPONENT...THEREBY KEEPING THE 1 KM
SHEAR IN CHECK. AS SUCH THE TORNADIC POTENTIAL IS DIMINISHING WITH
THE GREATEST TORNADIC POTENTIAL TARGETING SOUTHWEST MO. DEEP-LAYER
MOISTURE INCREASES MARKEDLY EARLY THIS EVENING WITH PRECIPITABLE
WATERS OF 1.80-2.00 INCHES COVERING MUCH OF EAST & SOUTHEAST KS.
AS SUCH HEAVY RAINS ARE A CERTAINTY BUT THE 1 & 3-HOUR FLASH FLOOD
GUIDANCE IS ~2.80 INCHES & ~3.50 INCHES RESPECTIVELY. WITH THE
SURFACE TROUGH PUSHING THROUGH SOUTHEAST KS ~9-10PM THE SEVERE
POTENTIAL WOULD QUICKLY DIMINISH BY MID-EVENING.

THU-THU NIGHT:
SCATTERED SHOWERS & THUNDERSTORMS ARE SLATED FOR MUCH OF THE AREA
AS A WEAK SURFACE HIGH PUSHING EAST ACROSS THE MID/UPPER MS
VALLEY WITH WEAK LOW PRESSURE POSITIONED OVER THE PANHANDLES. THIS
WOULD ENABLE A LOWER-DECK MOISTURE CHANNEL TO GET BETTER DEFINED
FROM MOST OF CENTRAL OK TO WESTERN KS. WITH THE NEXT (ALBEIT WEAK)
MID-LEVEL SHORTWAVE MOVING SE OVER WESTERN KS SCATTERED SHOWERS &
THUNDERSTORMS WOULD SPREAD E-SE ACROSS THE REGION.

FRI-SAT NIGHT:
MOISTURE REMAINS PLENTIFUL FOR MOST PERIODS BUT THE ABSENCE OF
LOWER-DECK BOUNDARIES CONTINUES TO MAKE PIN-POINTING GREATEST
THUNDERSTORM POTENTIAL DIFFICULT. AS SUCH HAVE ASSIGNED 20-30%
POPS TO MOST AREAS FOR THESE PERIODS.

.LONG TERM...(SUNDAY THROUGH WEDNESDAY)
ISSUED AT 357 PM CDT WED JUL 1 2015

IT`LL BE A WET START TO THE WORK-WEEK AS A STRONG UPPER-DECK WAVE
IS STILL SCHEDULED TO SURGE E FROM SASKATCHEWAN & MANITOBA TO
ONTARIO. THIS CHARACTER WILL DRIVE A COLD FRONT INTO KICT COUNTRY
SUNDAY NIGHT BUT WITH THE UPPER-DECK WAVE MOVING DUE E THE FRONT
IS LIKELY TO STALL OVER KICT COUNTRY MON & MON NIGHT. THE GFS HAS
AN ALMOST W-E ORIENTATION TO THE STALLING FRONT WHEREAS THE ECMWF
HAS THE FRONT DRAPED FROM SOUTHERN IA...ACROSS CENTRAL KS...TO THE
OK/TX PANHANDLES. REGARDLESS SHOWERS & EMBEDDED THUNDERSTORMS ARE
A GOOD BET FOR THE NEIGHBORHOOD FROM MON THRU TUE NIGHT.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z THURSDAY EVENING)
ISSUED AT 706 PM CDT WED JUL 1 2015

THE SURFACE FRONT IS MOVING ACROSS THE FORECAST AREA...IT IS
THROUGH KHUT/KRSL/KSLN AND IS RIGHT ON TOP OF KICT AS OF 00Z.
THUNDERSTORMS MAY IMPACT THE KICT AND KCNU TERMINALS THROUGH THE
EVENING AND EARLY OVERNIGHT HOURS...BUT BEYOND THAT...LOW CLOUDS
WILL BE THE MAIN CONCERN...MVFR CEILINGS POSSIBLE DURING THE EARLY
MORNING HOURS. WINDS WILL CONTINUE TO SWITCH TO THE NORTH AS THE
FRONT CONTINUES ITS SOUTHWARD MARCH WITH NORTHERLY WINDS
PERSISTING THROUGH THE DAY THURSDAY AS WELL.
