AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
253 PM CDT SUN AUG 7 2011

.DISCUSSION...

DAYS 1-2...

THE MAIN FORECAST FOCUS WILL BE ON THE CHANCE FOR THUNDERSTORMS
TONIGHT.

WV IMAGERY AND 12Z UPPER AIR ANALYSIS INDICATES A FAIRLY ZONAL FLOW
ALOFT ACROSS THE WESTERN HIGH PLAINS REGION. MEANWHILE, AN UPPER
LEVEL TROUGH OF LOW PRESSURE ACROSS SOUTHERN ALBERTA, CANADA IS
SLIDING SLOWLY EASTWARD. A +70KT UPPER LEVEL JET CORE IS STREAMING
EAST ACROSS NORTHERN CALIFORNIA, NORTHERN NEVADA, AND INTO NORTHERN
UTAH. MODEST MOISTURE IS IN PLACE ACROSS THE AREA WITH SURFACE
DEWPOINTS IN THE MID 50S(F) ACROSS OUR FAR SOUTHWESTERN ZONES WITH
PRIMARILY 60S(F) ELSEWHERE. AT THE SURFACE, AN AREA OF LOW PRESSURE
IS STRENGTHENING ACROSS EAST CENTRAL COLORADO NEAR THE KANSAS BORDER
WITH AN ATTENDANT FRONTAL BOUNDARY EXTENDING EAST ACROSS WEST
CENTRAL KANSAS.

SHORT RANGE MODELS INDICATE THE UPPER LEVEL TROUGH IN SOUTHWESTERN
CANADA MOVING EAST-SOUTHEAST ALONG THE CANADIAN BORDER INTO THE
EXTREME NORTHERN PLAINS TONIGHT. MEANWHILE, THE UPPER LEVEL JET CORE
IN THE INTERMOUNTAIN WEST WILL NOSE EAST INTO THE WESTERN HIGH
PLAINS OF WESTERN NEBRASKA, NORTHEASTERN COLORADO, AND NORTHWESTERN
KANSAS BY EARLY MONDAY. TOGETHER, THIS WILL BRING THE POSSIBILITY
FOR THUNDERSTORMS THIS EVENING THROUGH MONDAY MORNING ACROSS THE
DAKOTAS, NEBRASKA, AND AS FAR SOUTH AS WESTERN KANSAS. AS THE JET
CORE ALOFT APPROACHES FROM THE WEST, SURFACE LOW PRESSURE WILL
CONTINUE TO STRENGTHEN AS IT BEGINS TO EDGE EASTWARD FROM EAST
CENTRAL COLORADO INTO WEST CENTRAL KANSAS THIS EVENING. AS IT DOES
SO, THE ATTENDANT FRONTAL BOUNDARY ACROSS WEST CENTRAL KANSAS WILL
LIFT SLIGHTLY AND VERY SLOWLY NORTHWARD. INCREASED LOW LEVEL FORCING
COMBINED WITH THE HELP OF INCREASING DYNAMIC SUPPORT ALOFT ALONG
WITH STEEPENING LOWER LEVEL LAPSE RATES AND INSTABILITY, WILL LEAD
TO THE LIKELY DEVELOPMENT OF THUNDERSTORMS ALONG AND NORTH OF THE
FRONT AS IT CRAWLS NORTHWARD ACROSS CENTRAL KANSAS. THIS WILL
PLACE THE BEST CHANCE FOR PRECIP CHANCES ACROSS EXTREME NORTH AND
NORTHEASTERN PORTIONS OF THE CWA THIS EVENING. WILL RETAIN THE 40
POPS ACROSS THIS AREA WITH SLIGHT POPS ELSEWHERE. A COLD FRONT IS
PROGGED TO PUSH SOUTHEAST ACROSS WESTERN KANSAS MONDAY WITH
SURFACE HIGH PRESSURE FILLING IN BEHIND IT LEADING TO FAIRLY DRY
CONDITIONS ACROSS WESTERN KANSAS THROUGH THE END OF THE PERIOD
LATE TUESDAY AFTERNOON.

TEMPERATURES ARE EXPECTED TO BE NEAR SEASONAL EARLY IN THE PERIOD IN
WAKE OF A COLD FRONT PROGGED TO PUSH ACROSS WESTERN KANSAS BY MID TO
LATE AFTERNOON MONDAY. FOR TONIGHT, A SOUTH TO SOUTHWESTERLY LOW
LEVEL FLOW ACROSS SOUTH CENTRAL AND SOUTHWEST KANSAS WILL HELP KEEP
TEMPERATURES FAIRLY MILD TONIGHT WITH LOWS PRIMARILY IN THE 70S(F).
A FEW MID TO UPPER 60S(F) ARE POSSIBLE NORTH AND WEST. FOR MONDAY,
HIGH TEMPERATURES WILL FALL A FEW DEGREES FROM TODAY AS THE COLD
FRONT PUSHES SOUTHEAST ACROSS WEST CENTRAL AND SOUTHWEST KANSAS BY
MID DAY. THE NAM, GFS, AND UKMET SHOW H85 TEMPERATURES RANGING FROM
THE LOWER TO MID 20S(C) BEHIND THE FRONT WITH NEAR 28C ACROSS
EXTREME SOUTHEASTERN PORTIONS OF THE CWA BY MID AFTERNOON. LOOK
FOR HIGHS MAINLY UP INTO THE 90S(F) ACROSS THE FORECAST AREA
MONDAY AFTERNOON WITH JUST ABOVE 100F VERY LIKELY AHEAD OF THE
FRONT IN SOUTH CENTRAL KANSAS WHERE THE FRONT IS NOT EXPECTED TO
PUSH THROUGH UNTIL MID TO LATE AFTERNOON. SURFACE HIGH PRESSURE
SLIDING EAST ACROSS THE NORTHERN PLAINS TUESDAY WILL INFLUENCE AN
EAST TO SOUTHEASTERLY UPSLOPE FLOW ACROSS WESTERN KANSAS HELPING
TO KEEP TEMPERATURES NEAR SEASONAL TUESDAY. TEMPERATURES AT H85 WILL
RANGE FROM THE LOWER 20S(C) ACROSS THE NORTHEASTERN PORTION OF THE
CWA TO NEAR 30C IN THE FAR SOUTHWEST. EXPECT HIGHS UP INTO THE
90S(F) FOR THE MOST PART TUESDAY AFTERNOON. WILL NEED TO LOWER
HIGHS A COUPLE DEGREES ACROSS OUR SOUTHEAST ON TUESDAY AFTERNOON
WHILE INCREASING THEM A COUPLE DEGREES OR SO SOUTHWEST. WILL MAKE
ONLY MINOR ADJUSTMENTS TO TEMPERATURES THROUGHOUT THE REST OF THE
PERIOD.

DAYS 3-7...

MODELS THIS MORNING CONTINUE TO INDICATE THAT A DECENT CHANCE FOR
STORMS WILL BE POSSIBLE TUESDAY NIGHT INTO EARLY WEDNESDAY AS WARM
AIR ADVECTION/ISENTROPIC LIFT IMPROVES NORTH OF A STATIONARY FRONT
WHICH WILL EXTEND FROM NORTHEAST COLORADO ACROSS SOUTHWEST KANSAS.
UPPER LEVEL JET DYNAMICS ALONG WITH MOISTURE POOLING NORTH OF THIS
BOUNDARY CONTINUES TO FAVOR OUR NORTHERN COUNTY WARNING AREA WHICH
CURRENTLY IS OUTLINED WELL IN THE GRIDS WITH HIGH CHANCE POPS. AS A
RESULT NO MAJOR ADJUSTMENTS PLANNED WITH THE POSSIBLE EXCEPTION OF
FOLLOWING THE PREVIOUS SHIFTS TRENDS AND RAISING POPS A LITTLE MORE
IN THE HAYS AREA. IN ADDITION GIVEN THE CLOUDS, PRECIPITATION AND
THE LOCATION OF THE 850MB BAROCLINIC ZONE THE TEMPERATURES IN OUR
NORTH ARE ALSO EXPECTED TO BE ON THE COOL SIDE. THE ONLY QUESTION
WITH THESE COOLER TEMPERATURES ON WEDNESDAY WILL BE HOW FAR SOUTH
AND WEST TO EXTEND THEM. RAIN COOLED AIR FROM THE OVERNIGHT
CONVECTION MAY INDEED KEEP THIS BOUNDARY A LITTLE FURTHER SOUTH THAN
WHAT PREVIOUSLY THOUGHT SO HAVE DECIDED TO BEGIN TRENDING
TEMPERATURES DOWN SLIGHTLY MORE TOWARDS THE COOLER GUIDANCE IN THE
GARDEN CITY, DODGE CITY TO MEDICINE LODGE AREAS.

SUBTLE UPPER LEVEL WAVES ARE THEN EXPECTED TO RIPPLE ALONG THE FLOW
UNTIL A MORE SIGNIFICANT UPPER LEVEL TROUGH EXITS TO ROCKIES AND
CROSSES THE NORTHERN PLAINS ON FRIDAY. THE GFS AND ECMWF WERE BOTH
IN GOOD AGREEMENT WITH ANOTHER FRONT CROSSING SOUTHWEST KANSAS ON
FRIDAY AS THIS UPPER LEVEL TROUGH MOVES SOUTHEAST TOWARDS THE MID
MISSISSIPPI VALLEY.  AT THIS TIME THE MODELS SUGGEST THAT THIS FRONT
WILL MOVE INTO OKLAHOMA AND THE TEXAS PANHANDLE BEFORE BECOMING
STATIONARY. AS RESULT IT THE BETTER OPPORTUNITY FOR PRECIPITATION
ACROSS SOUTHWEST KANSAS WILL ACCOMPANY THIS FRONT LATE FRIDAY WITH A
CHANCE OF LINGERING STORMS NORTH OF THIS FRONT NEAR THE OKLAHOMA
BORDER FRIDAY NIGHT.

OVER THE WEEKEND A DEVELOPING UPPER LEVEL RIDGE OVER THE WESTERN
UNITED STATES WILL BEGIN TO SHIFT EASTWARD TOWARDS THE ROCKIES AND
THE STATIONARY FRONT WILL START TO LIFT BACK NORTH INTO WESTERN
KANSAS AS A WARM FRONT. UPSLOPE FLOW ALONG WITH ISENTROPIC LIFT
NORTH OF THIS FRONT EACH DAY COULD EASILY GIVE RISE TO A CHANCE OF
LATE DAY OR OVERNIGHT SHOWERS AND THUNDERSTORMS. AS FOR TEMPERATURES
WILL BEGIN A SLOW WARMING TREND BUT IF THE 850MB TEMPERATURES DO
VERIFY THEN HIGHS THIS WEEKEND WILL MAINLY BE IN THE 90S.

&&

.AVIATION...

MULTIPLE BOUNDARIES WERE LOCATED ACROSS SOUTHWEST KANSAS EARLIER
THIS AFTERNOON. THE POTENTIAL STILL  EXISTS FOR A FEW STORMS TO
DEVELOP NEAR THESE BOUNDARIES AS TEMPERATURES CLIMB TO AROUND 100
DEGREES. AS A RESULT WILL KEEP A MENTION OF CB GOING IN THE TAFS AT
ALL THE TAF SITES EITHER LATE TODAY OR EARLY THIS EVENING. WINDS
WILL ALSO BE VARIABLE EARLY THIS AFTERNOON GIVEN THESE BOUNDARIES
BUT BY MID DAY THE GENERAL DIRECTION SHOULD BE SOUTH/SOUTHEAST AT
ALL TAF SITES.

HIGH DEWPOINTS AND AN UPSLOPE FLOW DEVELOPING IN THE HAYS AREA AFTER
MIDNIGHT MAY ALSO GIVE WAY TO SOME LOW CLOUDS OR SOME LIGHT MIST/FOG
EARLY MONDAY MORNING. AT THIS TIME DID INTRODUCE A SCATTERED 015
DECK AFTER MIDNIGHT BUT CONFIDENCE IS NOT HIGH YET TO GO AHEAD WITH
IFR OR MVFR CIGS.
