AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
1157 AM CDT MON JUL 6 2015

.UPDATE...
ISSUED AT 1154 AM CDT MON JUL 6 2015

UPDATED TO RAISE TEMPS TODAY ALONG WITH KEEPING UP WITH CONVECTIVE
TRENDS.

CURRENT TEMPS ARE ALREADY AT OR VERY CLOSE TO FORECAST MAX TEMPS
TODAY OVER MAINLY SOUTH CENTRAL KS...SO WENT AHEAD AND BUMPED
THOSE UP A FEW DEGREES. THIS LOOKS TO BE THE RESULT OF LESS CLOUD
COVER THAN EXPECTED. ALSO ADJUSTED POPS TO SLOW THINGS DOWN BY A
FEW HOURS BASED ON CURRENT TRENDS. THINKING THAT PRECIP WILL NOT
MAKE IT DOWN TO WICHITA UNTIL AROUND OR AFTER 4 PM WITH SE KS
REMAINING DRY FOR MOST OF THE DAY.

.SHORT TERM...(TODAY THROUGH WEDNESDAY)
ISSUED AT 252 AM CDT MON JUL 6 2015

THE POTENTIAL FOR HEAVY RAIN REMAINS THE PRIMARY CONCERN STARTING
THIS AFTERNOON/EVENING AND CONTINUING PERIODICALLY THROUGH AT
LEAST WEDNESDAY AND A FLASH FLOOD WATCH WILL BE ISSUED FOR ALL OF
SOUTHEAST KANSAS AND PORTIONS OF SOUTH CENTRAL KANSAS. THIS WATCH
WILL BE IN EFFECT FROM THIS EVENING THROUGH WEDNESDAY EVENING.

A COLD FRONT WAS SITUATED ACROSS THE HIGH PLAINS OF NORTHWEST KANSAS
EXTENDING NORTH AND EAST ACROSS NORTHEAST NEBRASKA EARLY THIS
MORNING. WIDESPREAD SHOWERS AND THUNDERSTORMS DEVELOPED ALONG AND
NORTH OF THE FRONT ACROSS THE NORTHERN PLAINS. A SHORTWAVE TROUGH
MOVING ACROSS THE NORTHERN PLAINS STATES TODAY WILL HELP DRIVE THE
FRONT SOUTH INTO THE CENTRAL PLAINS STATES THIS AFTERNOON AND
TONIGHT. BY 00Z...THE NAM/GFS ARE IN REASONABLE AGREEMENT DRIVING
THE FRONT NEAR THE KANSAS TURNPIKE CORRIDOR. DEWPOINT TEMPERATURES
ARE PROGGED TO POOL INTO THE LOWER 70S ALONG AND SOUTH OF THE FRONT
RESULTING IN MLCAPES EXCEEDING 2000 J/KG.  MINIMAL CINH/STRONG
BUOYANCY ALONG WITH LOW-LVL MASS CONVERGENCE ALONG THE FRONT WILL
RESULT IN WIDESPREAD THUNDERSTORM COVERAGE THIS AFTERNOON AND
EVENING. PWATS ARE PROGGED TO CLIMB TO AROUND 2.25 INCHES OR THE
99TH PERCENTILE THIS EVENING WHILE THE LAYER WARM CLOUD DEPTH
DEEPENS CONSIDERABLY ALONG THE FRONTAL ZONE. THIS DEEP CLOUD LAYER
IS EXPECTED TO RESULT IN EFFICIENT RAIN PRODUCTION AND THE POTENTIAL
FOR FLASH FLOODING AS H9-H75 FLOW REMAINS PARALLEL TO THE FRONT
AND MESO-BETA ELEMENT VECTORS ARE PROGGED TO REMAIN LESS THAN 15
KNOTS ACROSS THE AREA THROUGH THE EVENING HOURS. A LARGE AREA OF
RAINFALL EXCEEDING 2 INCHES WITH LOCALLY HIGHER AMOUNTS OVER 3
INCHES APPEARS LIKELY.

TUE-WED...HIGHER PROBABILITIES FOR PRECIPITATION MAY RESIDE SOUTH OF
THE AREA DURING THE DAY ON TUESDAY AS A STABLE POST-FRONTAL REGIME
DEVELOPS ACROSS THE CENTRAL PLAINS OF KANSAS. ANOTHER SHORTWAVE
TROUGH IS PROGGED TO LIFT OUT OF THE SOUTHERN HIGH PLAINS BRINGING
INCREASING CHANCES FOR DEEP MOIST CONVECTION INCLUDING ADDITIONAL
ROUNDS OF HEAVY RAINFALL TUESDAY NIGHT INTO WED. THE GFS MAINTAINS
THE MORE PRONOUNCED H85 MOISTURE TRANSPORT ACROSS MAINLY SE KANSAS
WHILE THE NAM WOULD INCLUDE MORE OF SOUTH CENTRAL KS.

.LONG TERM...(THURSDAY THROUGH SUNDAY)
ISSUED AT 252 AM CDT MON JUL 6 2015

UNSETTLED WEATHER WILL REMAIN IN PLACE ACROSS THE CENTRAL PLAINS
STATES AT THE START OF THE PERIOD AS A MID/UPPER TROUGH REMAINS
ANCHORED ACROSS CALIFORNIA AND THE SUBTROPICAL RIDGE IS CONFINED
TO THE SOUTHEAST STATES. THIS WILL KEEP WEAK SOUTHWEST FLOW ACROSS
THE CENTRAL PLAINS STATES ALLOWING THE TROPICAL PLUME OF MOISTURE
TO REMAIN ENTRENCHED ACROSS THE REGION. THIS RIDGE IS PROGGED TO
RETROGRADE THROUGH THE WEEKEND WITH RISING HEIGHTS/INCREASING
THICKNESS PROGGED ACROSS THE CENTRAL PLAINS. THIS SHOULD RESULT IN
RISING TEMPERATURES AND LOWER PROBABILITIES FOR PRECIPITATION AS
WE MOVE THROUGH THE WEEKEND.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z TUESDAY MORNING)
ISSUED AT 606 AM CDT MON JUL 6 2015

COLD FRONT STRETCHING FROM EASTERN NEBRASKA TO FAR NORTHWEST KS
EARLY THIS MORNING...WILL PUSH SLOWLY SOUTHWARD TODAY...REACHING
FAR SOUTHEAST KANSAS TO SOUTHWEST OKLAHOMA BY LATE TONIGHT.
SCATTERED THUNDERSTORMS SHOULD DEVELOP ALONG FRONT IN CENTRAL
KANSAS AROUND MIDDAY OR EARLY AFTERNOON...WITH STORM COVERAGE
INCREASING ALONG FRONT TOWARD EVENING AS IT SLIDES INTO SOUTH
CENTRAL TO EAST CENTRAL KANSAS. WIDESPREAD THUNDERSTORMS WITH
HEAVY RAINFALL ARE EXPECTED NEAR THIS FRONT TONIGHT IN SOUTH
CENTRAL AND SOUTHEAST KS. RESTRICTED VISIBILITIES/CEILINGS CAN BE
EXPECTED AS THESE STORMS MOVE THROUGH THE TAF SITES...WITH
STRONG/VARIABLE WIND GUSTS POSSIBLE WITH THE STRONGEST STORM
CELLS. SOUTH WINDS WILL SHIFT TO NORTHERLY BEHIND THE FRONTAL
PASSAGE.
