AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
656 PM CDT TUE JUL 7 2015

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

.SYNOPSIS...
ISSUED AT 310 PM CDT TUE JUL 7 2015

WATER VAPOR IMAGERY AND REGIONAL 88D`S SHOW AN MCV SPINNING OVER
SW OK AND STARTING TO LIFT SLOWLY NORTHEAST. THE FRONT THAT SWEPT
THROUGH LAST EVENING IS NOW SITUATED FROM NORTHERN AR INTO
SOUTHERN OK.

&&

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 310 PM CDT TUE JUL 7 2015

THE UPPER CIRCULATION OVER SW OK IS EXPECTED TO DRIFT NORTHEAST
TONIGHT TRACKING OVER SE KS BY EARLY WED MORNING. MOISTURE
TRANSPORT IN THE 900-800MB LAYER WILL RAMP UP JUST EAST OF THE
UPPER FEATURE TONIGHT FOCUSING OVER EASTERN OK/SE KS. WITH
PRECIPITABLE WATER VALUES OVER 2" WOULD EXPECTED VERY HIGH
RAINFALL RATES WITH ANY SHOWERS OR STORMS THAT DEVELOP. CURRENT
THINKING IS THAT THAT THE FLASH FLOOD WATCH LOOKS GOOD AS WOULD
EXPECT ANOTHER ROUND OF FLOOD WARNINGS TONIGHT EAST OF THE KS
TURNPIKE WITH WICHITA BEING ON THE NW FRINGES OF THE MORE
WIDESPREAD RAINFALL. FOR WED MORNING THE MCV WILL BE APPROACHING
THE OZARK REGION AS IT CONTINUES TO LIFT SLOWLY NORTHEAST. WE
SHOULD SEE THE RAINFALL DECREASE FROM WEST TO EAST THROUGHOUT THE
DAY WITH ONLY NORTHEAST FRINGES SEEING RAINFALL BY THE AFTERNOON.

THERE IS DECENT MODEL AGREEMENT THAT ANOTHER IMPULSE WILL MOVE OUT
OF THE CENTRAL ROCKIES AND ACROSS NW KS/SW NEBRASKA WED NIGHT. IN
RESPONSE TO THIS FEATURE 850-700MB MOISTURE TRANSPORT ALONG WITH
ISENTROPIC LIFT WILL QUICKLY INCREASE OVER SW KS WITH THIS AREA OF
LIFT SPREADING EAST LATE WED NIGHT INTO THU MORNING. SO MUCH OF
THE AREA SHOULD SEE SOME SHOWERS AND STORMS LATE WED NIGHT INTO
THU MORNING WITH WESTERN AND NORTHERN PORTIONS OF THE FORECAST
AREA HAVING THE HIGHEST CHANCES.

CONFIDENCE IS HIGH THAT TEMPS WILL REMAIN BELOW NORMAL FOR BOTH
WED AND THU WITH PLENTY OF CLOUD COVER AND PERIODIC CHANCES FOR
RAIN.

.LONG TERM...(FRIDAY THROUGH TUESDAY)
ISSUED AT 310 PM CDT TUE JUL 7 2015

THE TREND OVER THE SOUTHERN AND CENTRAL PLAINS STARTING FRIDAY
WILL BE FOR UPPER RIDGING TO SLOWLY BUILD-IN. BY SAT THE UPPER
RIDGE WILL BE CENTERED OVER THE ARKLATEX REGION AND WILL SLOWLY
SHIFT WEST ON SUN INTO MON. THIS PATTERN CHANGE WILL RESULT IN
WELL ABOVE NORMAL TEMPS STARTING FRI WITH HIGH CONFIDENCE IN
LOCATIONS ALONG AND WEST OF I-135 AT THE CENTURY MARK BY SUN AND
REMAINING FOR MON.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z WEDNESDAY EVENING)
ISSUED AT 654 PM CDT TUE JUL 7 2015

MAIN SYNOPTIC FRONTAL BOUNDARY HAS SHIFTED WELL SOUTH OF THE
FORECAST AREA AT THIS TIME...BUT SCATTERED SHOWERS REMAIN ACROSS THE
SRN HALF OF KS AS A MID LEVEL BAROCLINIC ZONE REMAINS PARKED ACROSS
THE AREA.  SO WILL GO WITH PREVAILING VCSH FOR THE KICT/KCNU AND
KHUT TAF SITES AS THE SCATTERED SHOWERS REMAIN AROUND.

A WAVE ALONG THE MAIN FRONTAL BOUNDARY CURRENTLY LOCATED IN SRN OK
WILL BEGIN TO LIFT NORTHEAST LATE TONIGHT...PUSHING THE EFFECTIVE
FRONTAL BOUNDARY BACK INTO SE KS AFTER MIDNIGHT. THIS WILL LEAD TO A
LARGE AREA OF MODERATE SHOWERS AND EVEN SOME EMBEDDED THUNDER
INCREASING IN INTENSITY ACROSS MOST OF SE KS LATE TONIGHT INTO EARLY
WED MORNING. SO WILL GO WITH MVFR CIGS AND VSBY WITH MODERATE RAIN
AND VCTS FOR KCNU AFTER 07Z/WED THROUGH WED MORNING.  ON THE NW-WRN
EDGE OF THE MODERATE RAIN...EXPECT SOME STRATUS BUILD DOWN TO LEAD
TO AREAS OF DRIZZLE MIXED WITH SOME SHOWERS TO EXPAND OVER MOST OF
SOUTH CENTRAL KS.  SO WILL GO WITH MVFR CIGS/VSBY FOR THE KICT AND
KHUT TAFS FOR THIS CHANCE AFTER 09Z/WED.

THE KRSL AND KSLN TAF WILL BEGIN WITH VFR CONDITIONS...BUT THINK
SOME STRATUS BUILD DOWN ON THE NW SIDE OF THE SHOWERS WILL ALSO LEAD
TO MVFR CIGS TO MOVE INTO THESE AREAS AS WELL BY WED MORNING.
