Area forecast discussion, Aug 9, 11:48 PM CDT, 1 hour 8 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
1148 PM CDT SUN AUG 9 2015

...UPDATED FOR 06Z AVIATION DISCUSSION...

.SYNOPSIS...
ISSUED AT 352 PM CDT SUN AUG 9 2015

SCATTERED SHOWERS & A FEW THUNDERSTORMS CONTINUE ACROSS FAR SOUTH-
CENTRAL & SOUTHEAST KS ALONG A WEAK ENE-WSW ORIENTED STATIONARY
FRONT. WIDELY SCATTERED SHOWERS THAT CONTINUE TO MOVE E~30MPH OVER
CENTRAL KS ARE OCCURRING IN REGION OF WEAK ISENTROPIC ASCENT IN
315-320K LAYER. THE SCATTERED SHOWERS & EXTENSIVE CLOUD COVER HAVE
REALLY KEPT TEMPERATURES IN CHECK ACROSS THE REGION. AT 3 PM MOST
AREAS WERE ONLY IN THE MID-UPPER 80S WITH A SMATTERING OF READINGS
FROM 90-95F. THIS HAS RESULTED IN HEAT INDICES FROM 100-106 BEING
CONFINED TO EXTREME SOUTHEAST KS.

&&

.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 352 PM CDT SUN AUG 9 2015

THIS EVENING:
HEADLINE: THE INHERITED HEAT ADVISORY IS BEING CANCELLED FOR MOST
AREAS...THE EXCEPTIONS BEING MONTGOMERY & LABETTE COUNTIES WHERE
INDICES HAVE CREPT TO ~105F.

TONIGHT:
PER "SYNOPSIS" THE POTENTIAL FOR STRONG/SEVERE THUNDERSTORMS HAS
DECLINED. IN FACT...IN SPC'S LATEST UPDATE...THE SLIGHT RISK THAT
HAD BEEN ASSIGNED TO PRIMARILY SOUTHEAST KS HAS BEEN LOWERED TO
"MARGINAL". A MOISTURE-LADEN AIRMASS REMAINS ENTRENCHED ACROSS THE
REGION. (ESPECIALLY EASTERN KS WHERE PRECIPITABLE WATERS FROM 2.00
TO 2.20 INCHES RESIDE.) AS A WEAK MID-LEVEL SHORTWAVE SCOOTING ESE
CROSSES THE KS/MO BORDER LATE TONIGHT RAIN & THUNDERSTORMS SHOULD
SLOWLY DIMINISH IN A GENERAL W-E MANNER AS THIS WOULD SLOWLY PUSH
THE SURFACE-850MB FRONT FURTHER S/SE INTO OK.

MON-TUE NIGHT:
THERE'LL BE NICE WEATHER TO START THE WORK-WEEK AS LARGE & FAIRLY
STRONG HIGH SPREADS/GLIDES SE FROM THE NORTHERN PLAINS TOWARD THE
MID MS VALLEY.

WED & WED NIGHT:
THE NEXT CHANCE OF THUNDERSTORMS MAY ARRIVE CENTRAL KS VERY EARLY
WED MORNING AS A VERY WEAK MID-LEVEL SHORTWAVE TRIES TO DRIFT E
ACROSS THE CO/KS BORDER. THIS WOULD S-L-O-W-L-Y PUSH THE SURFACE
HIGH FURTHER E TO SET UP A FAIRLY WELL-DEFINED LOWER-DECK MOISTURE
CHANNEL FROM WESTERN OK TO WESTERN NEBRASKA ON WED. THE UPPER-DECK
HIGH (WHICH BEGINS TO SLOWLY RETROGRADE TOWARD NM) REMAINS STRONG
& THEREFORE DICTATES ONLY 20-30% POP ASSIGNMENT TO CENTRAL & SOUTH-
CENTRAL KS.

.LONG TERM...(THURSDAY THROUGH SUNDAY)
ISSUED AT 352 PM CDT SUN AUG 9 2015

WITH A DEEP(!) UPPER-DECK TROF DIGGING FROM QUEBEC TO THE CENTRAL
ATLANTIC COAST THE MASSIVE MID-UPPER HIGH WOULD SLOWLY RETROGRADE
TOWARD THE SOUTHWESTERN PLAINS...LEAVING THE KS NEIGHBORHOOD UNDER
A WEAK NW REGIME THROUGHOUT THESE PERIODS. WITH THE UPPER-DECK
RIDGE SLOWLY AMPLIFYING ANY CHANCES OF THUNDERSTORMS WOULD OCCUR
WELL TO THE NE & E OF THE NEIGHBORHOOD...MORE SPECIFICALLY FROM
THE MS VALLEY ON EAST.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z MONDAY NIGHT)
ISSUED AT 1148 PM CDT SUN AUG 9 2015

ALL OF THE GUIDANCE CONTINUES TO INDICATE THAT CONVECTION WILL
INCREASE IN COVERAGE DURING THE OVERNIGHT HOURS EXITING THE AREA
TOWARDS THE MORNING. HAVE KEPT THE VCTS FOR THIS POTENTIAL...BUT
HAVE NOT PUT A PREVAILING THUNDERSTORM IN DUE TO THE UNCERTAINTY
FOR LOCATION/TIMING THROUGHOUT THE NEXT 6 HOURS. ALL TERMINALS BUT
KRSL HAVE A CHANCE...BUT FEEL KHUT/KICT/KCNU HAVE THE BEST CHANCES
THROUGH 15Z. AFTER ANY CONVECTION WANES...WINDS WILL BE NORTH TO
NORTHEASTERLY DURING THE DAY WITH SCATTERED HIGH CLOUDS.
