AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
214 PM CDT SUN AUG 31 2014

...UPDATED SHORT TERM SECTION...

.SHORT TERM...(THIS EVENING THROUGH MONDAY)
ISSUED AT 213 PM CDT SUN AUG 31 2014

AN UPPER LEVEL SHORTWAVE IS PROGGED TO MOVE OUT OF THE CENTRAL
ROCKIES AND INTO THE CENTRAL HIGH PLAINS TONIGHT WITH AN 80+ KNOT
250MB JET OVER WESTERN KANSAS. WEST TO SOUTHWEST WINDS ARE
EXPECTED IN THE MID LEVELS OF THE ATMOSPHERE WITH 700MB
TEMPERATURES AROUND 15C AND 850MB TEMPERATURES AROUND 28 DEGREES.
TOWARDS THE SURFACE, AN AREA OF LOW PRESSURE WILL BE FOUND ACROSS
THE KS/CO BORDER THIS AFTERNOON AND SHIFT EASTWARD THIS EVENING
INTO THE OVERNIGHT PERIOD. A DRYLINE IS EXPECTED TO SET UP ACROSS
SOUTHWESTERN KANSAS THIS AFTERNOON MAINLY WEST OF A LINE FROM HAYS
TO DODGE CITY TO LIBERAL. WINDS WILL GENERALLY BE FROM THE SOUTH
SOUTHWEST BEHIND THIS FEATURE WITH SOUTH TO SOUTH SOUTHEAST WINDS
AHEAD OF THE DRYLINE. A FEW THUNDERSTORMS MAY FORM AHEAD OF THIS
DRYLINE DURING THE LATE AFTERNOON HOURS AND TREK EASTWARD AS THE
EVENING PROGRESSES. HOWEVER, THE CAP LOOKS TO BE HARD TO ERODE AND
THERE IS A CHANCE THAT THERE WILL BE NO ACTIVITY AT ALL.
MEANWHILE, A CLUSTER OF THUNDERSTORMS ARE EXPECTED TO FORM ACROSS
NORTHWEST KANSAS LATE THIS AFTERNOON AND MOVE INTO NORTH CENTRAL
KANSAS THIS EVENING INTO THE OVERNIGHT PERIOD. CAPE AND SHEAR
PROFILES LOOK ADEQUATE FOR A FEW OF THESE STORMS TO BECOME SEVERE
WITH LARGE HAIL AND DAMAGING WINDS BEING THE MAIN CONCERN.
OTHERWISE EXPECT INCREASING CLOUDINESS OVERNIGHT WITH WINDS
BECOMING LIGHT AND VARIABLE. THE BEST CHANCE OF MEASURABLE RAIN
WILL BE ACROSS THE I-70 CORRIDOR WITH LESSER CHANCES THE FARTHER
SOUTH YOU GO. ANY STORMS THAT DO FORM SHOULD MOVE OUT OF THE CWA
BY DAYBREAK TOMORROW. SKIES WILL BECOME MOSTLY CLEAR TOMORROW WITH
NORTHERLY WINDS SHIFTING TO THE NORTHEAST BY LATE AFTERNOON. AS
FOR TEMPERATURES, LOWS OVERNIGHT ARE EXPECTED TO RANGE FROM AROUND
60 DEGREES ACROSS WEST CENTRAL KANSAS TO AROUND 70 DEGREES ACROSS
SOUTH CENTRAL KANSAS. HIGHS TOMORROW WILL GENERALLY BE IN THE 80S.

.LONG TERM...(MONDAY THROUGH SATURDAY)
ISSUED AT 414 AM CDT SUN AUG 31 2014

THE FRONT FOLLOWING TONIGHTS STORM SYSTEM WILL REACH THE TEXAS
PANHANDLE AND ADJACENT WESTERN OKLAHOMA BY LATE MONDAY/MONDAY NIGHT.
THE DAYTIME HOURS MONDAY WILL BE FAIRLY TRANQUIL AS SUBSIDENCE WILL
PREVAIL IN THE WAKE OF THE DEPARTING SYSTEM. MODEST TEMPERATURES IN
THE 80S ARE EXPECTED. THE FRONT WILL STALL OUT MONDAY NIGHT AND WE
WILL FIND OURSELVES IN THE RIGHT ENTRANCE REGION OF AN UPPER
TROPOSPHERIC JET. THIS WILL ENHANCE FRONTOGENESIS IN THE 900-800MB
LAYER, SUPPORTING NOCTURNAL THUNDERSTORMS ONCE THE LOW LEVEL JET
DEVELOPS. THE MOST FAVORABLE LOCATION FOR MONDAY NIGHT/EARLY TUESDAY
STORMS WILL BE ACROSS SOUTH CENTRAL KANSAS, WHICH IS WHERE WE WILL
HAVE THE HIGHEST CHANCE POPS (AROUND 40 PERCENT). THIS FRONTAL ZONE
WILL NOT MOVE TUESDAY, AND WE WILL NEED TO CARRY SOME CHANCE POPS
THROUGH THE DAY ACROSS SOUTH CENTRAL KANSAS. DAYTIME TEMPERATURES
WILL BE AT OR JUST SLIGHTLY ABOVE AVERAGE FOR THE FIRST PART OF
SEPTEMBER (MID TO UPPER 80S AS A RULE). THE FRONT WILL EVENTUALLY
DISSOLVE BY LATE TUESDAY NIGHT AND ESPECIALLY BY WEDNESDAY, AS THE
LOW LEVEL FLOW FIELD BEGINS TO RESPOND TO LOWER PRESSURE MUCH
FARTHER NORTH WHERE THE POLAR JET WILL BE LOCATED. THE NEXT STORM
SYSTEM MID-WEEK WILL BE MUCH FARTHER NORTH WITH WEAK ZONAL FLOW
ACROSS COLORADO AND KANSAS FOR THE MOST PART. THIS WILL LEAD TO
WARMER TEMPERATURES AND DRIER WEATHER. WEDNESDAY AND THURSDAY
CONTINUE TO LOOK LIKE THE HOTTEST DAYS NEXT WEEK WITH AFTERNOON
HIGHS IN THE 95-100F RANGE FOR MUCH OF WESTERN AND SOUTHERN KANSAS.
THE NORTHERN POLAR JET STORM SYSTEM THAT WAS MENTIONED WILL MOVE
EAST ACROSS THE NORTHERN GREAT PLAINS/ADJACENT CANADIAN PRAIRIES
LATE IN THE WEEK, USHERING IN SOME MUCH COOLER TEMPERATURES ACROSS
THE NORTHERN PLAINS. THIS AIRMASS WILL LIKELY REACH KANSAS BY END OF
WEEK AND INTO THE WEEKEND. THERE APPEARS TO BE A FAIRLY STRONG
SIGNAL OF COOLER/WETTER WEATHER SEPTEMBER 6-8 TIME FRAME.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z MONDAY AFTERNOON)
ISSUED AT 1216 PM CDT SUN AUG 31 2014

A DRYLINE WILL SET UP BETWEEN THE GCK AND DDC TERMINAL THIS
AFTERNOON WITH SOUTH SOUTHWEST WINDS FELT ACROSS THE GCK TERMINAL AND
SOUTH TO SOUTH SOUTHEAST WINDS FELT AT THE HYS AND DDC TERMINALS. BREEZY
CONDITIONS WILL ALSO OCCUR ACROSS THE TAF SITES THIS AFTERNOON WITH
SUSTAINED WINDS ABOVE 20 KNOTS AND GUSTS ABOVE 30 KNOTS. WINDS
THEN DIE DOWN THIS EVENING BEFORE BECOMING LIGHT AND VARIABLE
OVERNIGHT. A FEW THUNDERSTORMS MAY DEVELOP ACROSS THE HYS AND DDC
TERMINALS EARLY THIS EVENING BRIEFLY REDUCING VISIBILITIES AND
CEILINGS. I HAVE PLACED A TEMPO GROUP IN THE TAFS TO REFLECT THIS.
