AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
1218 PM CDT WED SEP 17 2014

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

.SHORT TERM...(TODAY THROUGH FRIDAY)
ISSUED AT 320 AM CDT WED SEP 17 2014

WARM/MOIST ADVECTION IN THE 850-700MB LAYER IN RESPONSE TO AN
UPPER LEVEL DISTURBANCE MOVING SOUTHEAST ACROSS THE REGION WILL
RESULT IN SCATTERED SHOWERS/THUNDERSTORMS EARLY THIS MORNING
GENERALLY EAST OF THE FLINT HILLS OF EASTERN/SOUTHEAST KS.
THINKING MAJORITY OF ACTIVITY WILL EXIT EAST OUT OF KANSAS BY MID-
MORNING. GIVEN INSTABILITY/SHEAR COMBO...THE STRONGEST ACTIVITY
MAY BE CAPABLE OF PEA-DIME SIZE HAIL. AN OUTFLOW-REINFORCED
FRONTAL BOUNDARY IS EXPECTED TO DRAPE ITSELF SOUTHEAST-NORTHWEST
ACROSS THE AREA TODAY...BEING REINFORCED ALSO BY HIGH PRESSURE
BUILDING SOUTH ACROSS THE MIDWEST. THINKING ISOLATED TO WIDELY
SCATTERED AFTERNOON-EVENING THUNDERSTORMS ARE POSSIBLE IN VICINITY
OF THIS BOUNDARY...BEST CHANCES OVER SOUTHEAST KS DUE TO BETTER
LOW-LEVEL MOISTURE AND SOMEWHAT COOLER MID-LEVEL
TEMPERATURES...ALTHOUGH CANNOT RULE OUT AN ISOLATED STORM FURTHER
NORTHWEST TOWARD CENTRAL KS. STRENGTHENING WEAK- MODEST LOW-LEVEL
JET TONIGHT MAY ALLOW WIDELY SCATTERED STORMS TO DEVELOP AND/OR
FESTER NORTH OF THIS BOUNDARY TONIGHT...GENERALLY OVER
CENTRAL...EASTERN AND SOUTHEAST KS. ALL-IN-ALL...DESPITE STRONGER
500-300MB FLOW...WEAK 700MB FLOW SHOULD PRECLUDE WIDESPREAD SEVERE
WEATHER THROUGH TONIGHT...ALTHOUGH STRONGEST ACTIVITY THIS
AFTERNOON-EVENING MAY APPROACH LOW-END SEVERE LEVELS GIVEN STOUT
INSTABILITY. CONTINUED NORTHWEST FLOW ALOFT ALONG WITH THE
BOUNDARY BEGINNING TO WASH OUT MAY ALLOW A FEW STRAY STORMS
THROUGH THURSDAY ALONG/EAST OF I-135...ALTHOUGH NOT EXPECTING
ANYTHING MORE THAN ISOLATED COVERAGE. MID-LEVEL HIGH PRESSURE
BUILDING IN ALONG WITH BOUNDARY WASHING OUT COMPLETELY WILL RESULT
IN DRY CONDITIONS FOR FRIDAY ALL AREAS.

TEMPERATURE-WISE...NEAR TO ABOVE NORMAL TEMPERATURES ARE EXPECTED
THROUGH FRIDAY. READINGS TODAY COULD SOAR WELL INTO THE 90S OVER
MAINLY SOUTHERN/SOUTH-CENTRAL KS SOUTH OF THE FRONT.

.LONG TERM...(SATURDAY THROUGH TUESDAY)
ISSUED AT 320 AM CDT WED SEP 17 2014

STILL LOOKING LIKE THE POTENTIAL FOR WIDESPREAD SHOWERS AND
EMBEDDED THUNDERSTORMS THIS WEEKEND...AS REMNANTS OF TROPICAL
STORM ODILE PROGRESS NORTHEAST...EVENTUALLY PHASING WITH A DEEP
UPPER TROUGH APPROACHING FROM THE NORTHWEST...AND A STRONG COLD
FRONT APPROACHES FROM THE NORTHWEST. TIMING REMAINS THE PRIMARY
CHALLENGE...WITH THE 00Z ECMWF RUN COMING IN MUCH SLOWER THAN ITS
PREVIOUS RUNS...ALONG WITH THE LATEST GEM AND GFS. FOR NOW...WILL
AVOID MAJOR CHANGES...KEEPING BRUNT OF PRECIPITATION ON
SATURDAY...ALTHOUGH IF THE SLOWER SOLUTIONS VERIFY PRECIPITATION
WOULD LINGER WELL INTO SUNDAY. ALL- IN-ALL...TROPICAL CONNECTION
AND ASSOCIATED HIGH PRECIPITABLE WATERS AND POOR LAPSE RATES
SHOULD TEMPER STRONG/SEVERE STORM CHANCES...ALTHOUGH IT WILL FAVOR
LOCALLY VERY HEAVY RAINFALL IN SHORT AMOUNTS OF TIME. RAIN-COOLED
TEMPERATURES ANTICIPATED THIS WEEKEND...WITH CONTINUED COOL POST-
FRONTAL TEMPERATURES EARLY NEXT WEEK...WITH LOWS IN THE 50S AND
HIGHS IN THE 70S.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z THURSDAY AFTERNOON)
ISSUED AT 1208 PM CDT WED SEP 17 2014

A COLD FRONT WILL SINK SOUTHWARD ACROSS THE AREA THIS AFTERNOON
AND TONIGHT. THIS FRONT MAY PROVIDE A FOCUS FOR STORMS ACROSS
PORTIONS OF SOUTH CENTRAL AND SOUTHEAST KANSAS THIS AFTERNOON AND
EVENING. MOIST EASTERLY POST-FRONTAL FLOW WILL LIKELY RESULT IN
WIDESPREAD MVFR CIGS/VISIBILITIES AFTER 03-06Z. A SECONDARY
CONCERN WILL BE ISOLATED TO WIDELY SCATTERED STORM DEVELOPMENT
TONIGHT ABOVE THE FRONTAL ZONE POSSIBLY IMPACTING TAF SITES
ACROSS SOUTH CENTRAL AND SOUTHEAST KANSAS. REDUCED FLIGHT
CATEGORIES WILL LIKELY LINGER THROUGH THE MORNING HOURS ON
THURSDAY AS POST-FRONTAL EASTERLY FLOW PERSISTS ACROSS THE AREA.
