AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
331 PM CDT FRI SEP 28 2007

.DISCUSSION...

DAYS 1-2...

FORECAST CHALLENGE WILL BE CHANCES FOR THUNDERSTORMS THIS EVENING
AND SATURDAY NIGHT ALONG WITH HOW STRONG THE WINDS GET ON SATURDAY.

THE 12Z UA ANALYSIS SHOWED A BROAD UPPER RIDGE ACROSS THE CENTRAL
CONUS WITH A STRONG UPPER TROUGH OVER THE EASTERN GREAT LAKES AND
APPALACHIANS. ANOTHER TROUGH WAS DIGGING INTO THE NORTHWESTERN
CONUS WITH HEIGHT FALLS IN EXCESS OF 100 METERS NOTED OVER
WASHINGTON AND WESTERN OREGON. TO THE SOUTH OF THIS...A
SUBTROPICAL JET WAS EXPANDING ONSHORE IN THE SOUTHWEST WITH A FAIR
AMOUNT OF MID LEVEL MOISTURE SPREADING TOWARD THE CENTRAL PLAINS
AS EVIDENT ON THE WATER VAPOR IMAGERY.

AT THE SURFACE...A LOW PRESSURE TROUGH EXTENDED NORTH-SOUTH ACROSS
THE EASTERN PLAINS OF COLORADO. WIDELY SCATTERED THUNDERSTORMS
WERE DEVELOPING ALONG THE TROUGH OUT WEST AS WELL AS ALONG AN
OUTFLOW BOUNDARY LEFT OVER FROM THIS MORNINGS STORMS THAT HAD
MOVED TO A LOCATION ALONG HIGHWAY 83 FROM KGCK TO KLBL. SPC MESO
ANALYSIS WEBSITE WAS SHOWING A NARROW AXIS OF 3000 J/KG SURFACE
BASED CAPE THAT WAS LINED UP WITH THE OUTFLOW BOUNDARY. STORMS
ALONG THAT BOUNDARY SHOULD CONTINUE TO INTENSIFY WITH A FEW SEVERE
STORMS POSSIBLE LATE THIS AFTERNOON AND EARLY EVENING. STORMS WILL
HAVE A HARD TIME MOVING TOO FAR TO THE EAST...AWAY FROM THE
INSTABILITY AXIS SO THE CURRENT WATCH FROM SPC LOOKS GOOD.
CONVECTIVE ACTIVITY SHOULD BE DIMINISHING ONCE WE LOSE THE
AFTERNOON HEATING.

ON SATURDAY...THE WESTERN CONUS WAVE WILL BE TRACKING FAIRLY
RAPIDLY TO THE EAST. THE 12Z RUNS OF THE GFS/HIRES ECMWF AND UKMET
HAVE ALL COME IN LINE WITH EACH OTHER NOW THAT THE SYSTEM IS
MOVING INTO AN AREA WITH BETTER UA COVERAGE. THE MODELS ALL PUT
THE UPPER SYSTEM OVER NORTHERN UTAH BY SATURDAY EVENING AND INTO
THE COMMON BORDER REGION OF COLORADO/NEBRASKA AND KANSAS BY 12Z
SUNDAY. AS SURFACE PRESSURES CONTINUE TO DEEPEN OVER THE WESTERN
HIGH PLAINS...SUSTAINED SOUTHERLY WINDS WILL INCREASE TO AROUND 30
TO 35 MPH OVER MOST OF THE CWA. THE GRADIENT REMAINS RELATIVELY
WEAKER AROUND PRATT...COLDWATER AND MEDICINE LODGE. HAVE DECIDED
TO HOIST A WIND ADVISORY FOR SATURDAY FROM 15Z TO 00Z FOR ALL THE
COUNTIES EXCEPT THOSE IN THE SOUTHEAST.

ABUNDANT LOW LEVEL MOISTURE WILL BE IN PLACE AGAIN ON SATURDAY
AHEAD OF THE SURFACE TROUGH. AFTERNOON HEATING PLUS THE APPROACH
OF THE UPPER SYSTEM SHOULD RESULT IN SCATTERED THUNDERSTORMS
BREAKING OUT ALONG THE TROUGH IN THE AFTERNOON AND SPREADING
EASTWARD OVERNIGHT. SHOULD BE ENOUGH INSTABILITY AND SHEAR TO
PRODUCE A FEW SEVERE THUNDERSTORMS.

PACIFIC COOL FRONT WILL MOVE EAST ACROSS THE AREA EARLY SUNDAY.
COULD BE SOME LINGERING THUNDERSTORMS OVER THE EASTERN HALF OF THE
CWA SUNDAY MORNING BUT THIS SHOULD ALL GET SWEPT EAST DURING THE
DAY. HIGH TEMPERATURES WILL BE A LITTLE TRICKY GIVEN THE COOL
ADVECTION BATTLING THE DOWNSLOPE WARMING. MOS GUIDANCE FROM THE
NAM AND GFS DIVERGES SIGNIFICANTLY WITH HIGHS FROM THE NAM IN THE
LOWER 70S AND THE GFS PRODUCING HIGHS IN THE LOW TO MID 80S. GFS
MODEL SOUNDINGS ARE NOT QUITE THAT WARM SO TAKEN THE MIDDLE GROUND
WITH HIGHS IN THE MID/UPPER 70S.

DAYS 3-7...

TROPICAL THUNDERSTORM ACTIVITY CONTINUES TO BE CLUSTERED OVER THE
NORTHWEST TROPICAL PACIFIC AND BETWEEN 60 AND 80 DEGREES EAST
BETWEEN 10 AND 20 DEGREES NORTH. RELATIVE ATMOSPHERIC ANGULAR
MOMENTUM REMAINS ABOUT 2 AMU UNITS BELOW CLIMATOLOGY...AND THE
CALCULATED RELATIVE ATMOSPHERIC ANGULAR MOMENTUM TENDENCY HAS
BECOME NEGATIVE. SATELLITE IMAGERY SUGGESTS SOME EASTWARD
PROPAGATION OF THE TROPICAL NORTHWEST PACIFIC...BUT THERE IS
LITTLE INDICATION THAT ANY MAJOR ADJUSTMENT IS IN PROGRESS. AS
SUCH...THE MEAN LONG WAVE TROUGH LIKELY WILL REMAIN NEAR THE WEST
COAST WHILE A SERIES OF VIGOROUS UPPER LEVEL TROUGHS RIPPLE
THROUGH THE FLOW IN THE ANOMALOUSLY STRONG WESTERLY JET EXTENDING
FROM CENTRAL ASIA ACROSS THE MID PACIFIC RIDGE INTO THE WESTERN
UNITED STATES. THE MODELS HAVE BEEN STRUGGLING WITH TIMING AND
AMPLITUDES OF THE UPPER LEVEL TROUGHS EMBEDDED IN THE FLOW. THE
12Z GFS IS IN FAIRLY GOOD AGREEMENT WITH THE 00Z ECMWF AND LARGELY
WAS FOLLOWED FOR THE EXTENDED GRIDS. THE MODEL SOLUTIONS DIVERGE
ON THE STRENGTH AND TIMING OF THE HIGH AMPLITUDE TROUGH THAT MOVES
INTO THE CENTRAL UNITED STATES 6-7 OCTOBER. THE ECMWF AND 00Z
CANADIAN ARE A LITTLE SLOWER THAN THE OPERATIONAL GFS, AND A
NUMBER OF THE GFS ENSEMBLES ALSO SUPPORT A SLOWER SOLUTION. FOR
NOW...THE PREPONDERANCE OF EVIDENCE SUPPORTS A SLOWER SOLUTION AND
A CONTINUATION OF WARM WEATHER ACROSS THE CENTRAL PART OF THE
COUNTRY THROUGH SATURDAY 6 OCTOBER.

THE VIGOROUS UPPER LEVEL TROUGH THAT MOVES OVER THE CENTRAL PLAINS
SUNDAY LIFTS RAPIDLY NORTHEASTWARD...AND THE PACIFIC COLD FRONT
SHOULD BECOME STATIONARY ACROSS CENTRAL OKLAHOMA SUNDAY NIGHT. AS
THE VIGOROUS UPPER LEVEL TROUGH NEAR 160W THIS AFTERNOON DROPS INTO
THE MEAN TROUGH POSITION OVER THE WESTERN UNITED STATES SUNDAY NIGHT
AND MONDAY, INCREASING FLOW PERPENDICULAR TO THE ROCKIES WILL
SUPPORT LEE TROUGHING. THE OLD FRONTAL BOUNDARY WILL LIFT NORTHWARD
INTO WESTERN KANSAS DURING THE DAY MONDAY. EVEN THOUGH THE MID
LEVELS OF THE ATMOSPHERE WILL BE QUITE WARM...THERE MAY BE ENOUGH
CONVERGENCE ALONG THE WARM FRONT TO SUPPORT A FEW THUNDERSTORMS IN
THE NORTHERN ZONES BY LATE AFTERNOON. ADDITIONAL THUNDERSTORM
DEVELOPMENT SHOULD OCCUR OVER THE HIGHER TERRAIN OF COLORADO WITH
THE APPROACH OF THE UPPER LEVEL TROUGH LATE MONDAY AND MOVE INTO
WESTERN KANSAS MONDAY EVENING. STRONG UVV IN ADVANCE OF THE UPPER
LEVEL TROUGH WILL SUSTAIN THUNDERSTORMS THROUGH THE NIGHT AND INTO
TUESDAY MORNING AS THE PACIFIC FRONT PROGRESSES ACROSS WESTERN
KANSAS. GIVEN THE AMOUNT OF MOISTURE AVAILABLE...AT LEAST SCATTERED
THUNDERSTORMS SHOULD OCCUR.

TEMPERATURES WILL RADIATE NICELY TUESDAY NIGHT AS PACIFIC HIGH
PRESSURE BUILDS OVER KANSAS. THE STRONGEST UPPER LEVEL FLOW SHOULD
REMAIN NORTH OF KANSAS FOR THE REMAINDER OF THE WEEK AS THE NEXT
SYSTEM DIGS OVER THE WESTERN PART OF THE COUNTRY. ALTHOUGH THE
POSSIBILITY EXISTS THAT A MINOR WAVE EMBEDDED IN THE SUBTROPICAL
FLOW COULD MOVE ACROSS KANSAS LATER IN THE WEEK...TIMING OF SUCH
FEATURES THAT FAR OUT FALLS INTO THE NOISE CATEGORY. POPS CAN BE
INTRODUCED LATER WHEN THERE IS SOME SKILL IN IDENTIFYING AND
FORECASTING SUCH DETAILS.

&&

.AVIATION...

THE ATMOSPHERE OVER WESTERN KANSAS IS VERY UNSTABLE THIS
AFTERNOON...AND SCATTERED THUNDERSTORMS CAN BE EXPECTED TO OCCUR
ALONG AN UPPER LEVEL WARM FRONT OVER CENTRAL KANSAS AND ALONG A WEAK
OUTFLOW BOUNDARY FROM LIBERAL NORTHWARD TO NEAR GARDEN CITY.
ADDITIONAL THUNDERSTORMS WILL DEVELOP THIS AFTERNOON AND EVENING
OVER EASTERN COLORADO AND MOVE INTO WESTERN KANSAS BEFORE WEAKENING
TOWARD MIDNIGHT. CONSIDERABLE HIGH LEVEL CLOUDINESS WILL PREVAIL
OVER WESTERN KANSAS TONIGHT AND WILL REDUCE THE POTENTIAL FOR
STRATUS DEVELOPMENT. VISIBILITIES MAY BE RESTRICTED TO 3-5 MILES
BRIEFLY AROUND SUNRISE. LOW LEVEL SOUTHERLY FLOW WILL INCREASE TO
25-30 KNOTS SUSTAINED ON SATURDAY.
