AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
350 PM CDT THU JUN 26 2008

.DISCUSSION...

DAYS 1-2...
WATER VAPOR IMAGERY SHOWS A WEAK SHORTWAVE MOVING THROUGH COLORADO AND
NORTHERN NEW MEXICO THIS AFTERNOON. THE MODELS HINT AT THIS FEATURE
MOVING OUT THROUGH THE CENTRAL HIGH PLAINS THIS EVENING WHICH MAKES
SENSE GIVEN ITS CURRENT SPEED AND TRAJECTORY. CONVECTION OVER NORTHWEST
KANSAS LAST NIGHT AND EARLY THIS MORNING PRODUCED AN OUTFLOW BOUNDARY
THAT MOVED INTO WEST CENTRAL KANSAS FROM GREAT BEND THROUGH KALVESTA
AND SYRACUSE THIS MORNING. THIS FEATURE APPEARS TO BE WASHING OUT
SOME AS NEARLY ALL AWOS SITES SHOW THAT WINDS HAVE BECOME GUSTY
FROM THE SOUTH. ISOLATED SHOWERS AND THUNDERSTORMS WERE
DEVELOPING ALONG THE PALMER DIVIDE AND OFF THE RATON MESA THIS
AFTERNOON AS THE WAVE MOVES OUT OF THE ROCKIES.

EXPECT THE BEST CHANCES FOR THUNDERSTORMS TO BE OVER NORTHERN SECTIONS
OF THE CWA WHERE SOME LINGERING LOW LEVEL CONVERGENCE COULD FOCUS STORMS
IN THAT AREA. CONVERGENCE NEAR A WEAK HEAT LOW OVER SOUTHEAST COLORADO
COULD ALSO PRODUCE A FEW THUNDERSTORMS OVER SOUTHWEST KANSAS THIS
EVENING.

ON FRIDAY A DEVELOPING UPPER LOW IN THE NORTHERN STREAM WILL MOVE
OUT OF WESTERN CANADA INTO THE UPPER MIDWEST. THIS SYSTEM HAS BEEN
LONG FORECAST BY THE MODELS TO PUSH A COLD FRONT SOUTH ACROSS THE
CENTRAL HIGH PLAINS ON FRIDAY. THE NAM IS THE FASTEST WITH FRONTAL
PASSAGE WHILE THE GFS AND UKMET ARE A LITTLE SLOWER. TIMING OF
THIS FRONT WILL HAVE A BIG IMPACT ON HIGH TEMPERATURES ACROSS THE
CWA ON FRIDAY. IF IT SLOWS DOWN AN HOUR OR TWO THEN HIGH TEMPERATURES
COULD BE A CATEGORY HIGHER THAN CURRENTLY FORECAST. HAVE RAISED TEMPS
IN THE NORTHWEST CWA A FEW DEGREES. WIDELY SCATTERED THUNDERSTORMS
WILL BE POSSIBLE BY MID AFTERNOON ALONG THE FRONT ESPECIALLY OVER
THE EASTERN HALF OF THE CWA. THE MODELS STILL S HOW BETTER QPF
VALUES JUST BEHIND THE FRONT DURING THE EVENING SO WILL CONTINUE
WITH THE CHANCE POPS FOR THAT TIME PERIOD.

SATURDAY SHOULD BE A LITTLE COOLER WITH PARTLY CLOUDY SKIES. DID NOT
CHANGE THE MAX TEMP FORECAST AS IT APPEARS THE WARMER MAV GUIDANCE
IS IN BETTER AGREEMENT WITH MODEL SOUNDINGS FROM THE NAM AND GFS.

DAYS 3-7...
NOT REALLY AN EASY EXTENDED FORECAST.  FIRST QUESTION IS HOW FAR THE
FRONT GETS AND HOW MUCH HIGH TERRAIN THUNDERSTORMS THERE WILL BE
DRIFTING INTO AT LEAST THE FAR SOUTHWEST COUNTIES.  WILL CONTINUE
WITH THE BEST POPS NEAR EHA LATE SATURDAY AND INTO THE FIRST OF THE
WEEK.  WOULD NOT BE SURPRISED HOWEVER IF THIS HAS TO BE SHIFTED
NORTH.  THE LATEST GFS REALLY DRIES OUT THE BOUNDARY LAYER BUT I
HAVE MY DOUBTS.  LATER, THERE IS SOME QUESTION ABOUT THE AMOUNT OF
RIDGING THAT WILL TAKE PLACE OVER THE CENTRAL PLAINS.  THE ECMWF
REMAINS THE MOST AGGRESSIVE IN KEEPING WESTERLY FLOW ACROSS THE
REGION.  THE LATEST RUN OF THE GFS AMPLIFIES THE RIDGE THAT RESULTS
IN NORTHERLY UPPER FLOW ACROSS MY AREA FOR SEVERAL DAYS.  THE LATEST
CANADIAN IS MORE IN LINE WITH THE ECMWF.  I SEE NO NEED IN DEVIATING
FROM RECENT THINKING...THAT IS KEEPING A CHANCE OR AT LEAST SLIGHT
CHANCE OF TSRA IN THE EXTENDED AS MID LEVEL TEMPS REMAIN IN CHECK.
WITH A LITTLE BIT OF WESTERLY OR NORTHWESTERLY FLOW THERE SHOULD
STILL BE AT LEAST ISOLATED ACTIVITY MAINLY DURING THE EVENING
HOURS.  THE ECMWF ACTUALLY HAS A DECENT S/WV MOVING ACROSS TOWARDS
MID WEEK.

.AVIATION...

A FEW ISOLATED THUNDERSTORMS ARE POSSIBLE THIS EVENING WHICH WOULD
LOCALLY DROP CIGS...BUT COVERAGE COULD BE VERY SMALL.

1150 AM CDT THU JUN 26 2008 /350 AM MDT THU JUN 26 2008/

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF CENTRAL
KANSAS...SOUTH CENTRAL KANSAS...SOUTHWEST KANSAS AND WEST CENTRAL
KANSAS.

.DAY ONE...TODAY AND TONIGHT

AN UPPER LEVEL DISTURBANCE MOVING INTO THE PLAINS COULD SET OFF
SOME ISOLATED THUNDERSTORMS ACROSS WESTERN KANSAS LATE THIS
AFTERNOON AND EVENING. A FEW OF THE STORMS COULD BECOME SEVERE WITH
LARGE HAIL AND DOWNBURST WINDS BEING THE MAIN THREAT. IT APPEARS
THAT THE MOST LIKELY AREA FOR THUNDERSTORM DEVELOPMENT WILL BE ALONG
THE COLORADO BORDER AND IN AN AREA GENERALLY NORTH OF A LINE FROM
SYRACUSE TO GARDEN CITY AND LARNED.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

A COLD FRONT MOVING DOWN INTO WESTERN KANSAS ON FRIDAY WILL SET
OFF MORE THUNDERSTORMS DURING THE AFTERNOON AND EVENING. SOME OF
THE STORMS COULD BECOME SEVERE...WITH DAMAGING WINDS AND LARGE
HAIL THE PRIMARY THREAT. TIMING AND LOCATION ARE STILL
UNCERTAIN...BUT AT THIS POINT THE BEST AREA FOR SEVERE
THUNDERSTORMS WILL BE SOUTH AND EAST OF A JOHNSON TO GARDEN CITY
TO HAYS LINE.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT ANTICIPATED TODAY OR TONIGHT.
