AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
301 PM CDT SUN JUN 15 2008

.DISCUSSION...

DAYS 1-2...

THE PRIMARY FORECAST CHALLENGE WILL BE FOR THE CHANCE OF
THUNDERSTORMS DURING THE PERIOD.

WV IMAGERY AND 12Z UPPER AIR ANALYSIS INDICATES A RIDGE OF HIGH
PRESSURE REMAINING IN PLACE OVER THE DESERT SOUTHWEST WITH A
NORTHWESTERLY FLOW ALOFT ACROSS WESTERN KANSAS. A SOUTHERN BRANCH
OF AN UPPER LEVEL JET (+70KT) IS FLOWING SOUTHEAST ACROSS WESTERN
KANSAS AND DOWN INTO CENTRAL OKLAHOMA WHILE A NORTHERN BRANCH IS
STREAMING EAST ACROSS THE NORTHERN PLAINS OF THE DAKOTAS. AT THE
SURFACE, A COLD FRONT STRETCHING FROM EASTERN NEBRASKA SOUTHWEST
INTO EXTREME NORTHWEST KANSAS IS PUSHING SOUTH.

NUMERICAL MODELS ARE IN GENERAL AGREEMENT INDICATING THE UPPER LEVEL
PATTERN CHANGING VERY LITTLE DURING THE PERIOD WITH THE UPPER LEVEL
RIDGE REMAINING TO OUR SOUTHWEST WITH A NORTHWESTERLY FLOW ALOFT
ACROSS WESTERN KANSAS. A SERIES OF UPPER LEVEL S/WAVE DISTURBANCES
WILL CONTINUE TO CYCLE THROUGH THE NORTHWESTERLY FLOW THROUGH THE
END OF THE PERIOD WHICH WILL KEEP IN PLACE THE POSSIBILITY OF PRECIP
ACROSS THE CENTRAL PLAINS TONIGHT THROUGH TUESDAY. FOR TONIGHT, A
COLD FRONT PUSHING THROUGH THE CWA THIS AFTERNOON WILL BE THROUGH
THE AREA AND JUST TO OUR SOUTH AND EAST BY EARLY THIS EVENING. A
CHANCE OF THUNDERSTORMS IS POSSIBLE THIS EVENING IN ASSOCIATION WITH
THIS FRONT. AMPLE LOW LEVEL MOISTURE RETURN WILL BE PRESENT AHEAD OF
THE FRONT WITH DEWPOINTS AT H85 UP INTO THE MID TEENS(C). THE BETTER
CHANCE FOR THUNDERSTORMS WILL BE IN MORE EASTERN PORTIONS OF THE CWA
IN CONJUNCTION WITH BETTER UPPER LEVEL SUPPORT...INCLUDING THE UPPER
LEVEL JET MAX SHIFTING FROM WESTERN KANSAS EASTWARD INTO EASTERN
KANSAS. MAY BUMP UP POPS IN THE EXTREME EAST BUT CAPPING LEAVES A
BIT OF UNCERTAINTY. ANOTHER ROUND OF THUNDERSTORMS WILL BE POSSIBLE
AGAIN ON MONDAY AS A SURFACE HIGH JUST TO OUR NORTH SLIDES SLOWLY
SOUTHEAST DURING THE DAY WITH A SURFACE LOW JUST TO OUR SOUTH IN
WEST TEXAS. THIS WILL SET UP AN UPSLOPE FLOW ENVIRONMENT ACROSS MUCH
OF WESTERN KANSAS. AMPLE MOISTURE RETURN WILL BE PRESENT AGAIN
ACROSS THE FORECAST AREA...PARTICULARLY ALONG THE OKLAHOMA BORDER
WITH DEWPOINTS AT H85 UP INTO THE MID TEENS(C)... WITH THE SURFACE
LOW JUST TO OUR SOUTH IN WEST TEXAS AND EASTERN NEW MEXICO. BEST
CHANCE FOR PRECIP WILL BE MONDAY AFTERNOON AND EVENING. A NEARLY
SIMILAR SET UP WILL BE IN PLACE TUESDAY GIVING SOUTHWEST KANSAS
ANOTHER CHANCE AT A ROUND OF THUNDERSTORMS. WILL STAY WITH CURRENT
POPS FOR BOTH DAYS.

AS FOR TEMPERATURES, EXPECT LITTLE CHANGE IN LOW TEMPERATURES
TONIGHT FROM LAST NIGHT WITH THE COLD FRONT STALLING JUST TO OUR
SOUTH ACROSS THE OKLAHOMA BORDER. FOR TONIGHT, TEMPERATURES AT H85
WILL RANGE FROM AROUND 15C IN THE NORTH TO NEAR 20C ALONG THE
OKLAHOMA BORDER. EXPECT A DROP IN HIGH TEMPERATURES FROM SUNDAY INTO
MONDAY. TEMPERATURES AT H85 WILL RANGE FROM AROUND 15C TO THE LOWER
TO MID 20S(C) SOUTHWEST. INCREASED CLOUDINESS EARLY IN THE DAY FROM
THE ONSET OF AN EASTERLY UPSLOPE FLOW MAY HINDER HIGHS A BIT AS
WELL. EXPECT LITTLE CHANGE TO HIGHS ON TUESDAY AS THE EASTERLY
UPSLOPE FLOW REMAINS IN PLACE ACROSS THE FORECAST AREA. PLAN TO MAKE
SLIGHT ADJUSTMENTS TO TEMPERATURES.

DAYS 3-7...

FORECAST ISSUES ARE STILL DAILY THUNDERSTORM CHANCES AND
TEMPERATURES.

EASTERN HEMISPHERE TROPICAL CONVECTIVE FORCING INTERACTING WITH THE
EXTRATROPICS CONTINUES TO STRONGLY IMPACT THE GLOBAL CIRCULATION.
THE TROPICAL FORCING COVERS A LARGE REGION LOOSELY SEPARATED INTO
TWO AREAS.  ONE EXTENDS FROM THE INDIAN OCEAN INTO SOUTHEAST ASIA
WITH THE OTHER ACROSS MUCH OF THE EQUATORIAL WEST CENTRAL PACIFIC
OCEAN.  THE FORMER IS ENHANCING THE MONSOON SYSTEMS WHILE THE LATTER
IS TRYING TO EVOLVE INTO AN EASTWARD PROPAGATING COMPONENT INCLUDING
A MJO CONTRIBUTION.  AS DISCUSSED IN PAST AFDS, THE TROPICAL FORCING
INTERACTING WITH MIDLATITUDE NORTH-SOUTH MOUNTAINS IS SHIFTING ZONAL
MEAN EASTERLY WIND FLOW ANOMALIES POLEWARD INTO THE MIDLATITUDES.
ANOMALOUS WESTERLY WIND FLOW HAS BEEN INCREASING IN THE EQUATORIAL
ATMOSPHERE AND IS ALSO STARTING TO SHIFT INTO THE SUBTROPICS.  THAT
IS WHY A RETROGRESSION OF CIRCULATION ANOMALIES ACROSS THE PNA IS
STARTING (SEASONAL ISSUES UNDERSTOOD).

DURING THE NEXT FEW WEEKS I THINK THERE WILL BE A CIRCUIT TOWARD
OCTAL 5 IN THE WB (2007,08) GWO PHASE SPACE, FOLLOWED BY ANOTHER
COLLAPSE.  OVERALL, OUR LOW GLOBAL AAM BASE STATE IS PROBABLE TO
PERSIST UNTIL FURTHER NOTICE (AS HAS BEEN THE CASE FOR AT LEAST
THE PAST YEAR).  A PROBABLE SYNOPTIC EVOLUTION FOR OUR PART OF THE
WORLD WOULD BE TO EXPECT CONTINUED RETROGRESSION LEADING TO
UNSEASONABLY STRONG USA PACIFIC NORTHWEST TROUGHS.  REGARDLESS OF
THE WHITE NOISE DETAILS, THIS MEANS THE ACTIVE CENTRAL AND SOUTHERN
PLAINS MCS TRACK WEEK-1 IS LIKELY TO SHIFT BACK NORTH.  AS PART OF
AN ENHANCEMENT OF CLIMATOLOGY, THE NORTHERN PLAINS AND UPPER
MISSISSIPPI VALLEY MAY AGAIN BE STRONGLY IMPACTED BY MCS ACTIVITY
WEEKS 2-3 (AT LEAST) WHILE LOCATIONS SUCH AS THE DDC CWA BAKE.

I DID NOT MAKE LARGE CHANGES TO THE EXISTING FORECAST.  TRYING TO
TIME JUST WHAT DAYS (LATE PMS/NITES) WILL HAVE THE BEST STORM
OPPORTUNITIES IS ALSO WHITE NOISE.  I MAINTAINED THE DAILY SLIGHTLY
ABOVE CLIMATOLOGY POPS WHILE INCREASING TEMPERATURES TO NEAR TO
ABOVE NORMAL BY NEXT WEEKEND.  UPSLOPE LOW LEVEL MOISTURE
TRANSPORT INTO THE HIGH PLAINS, AMPLE INSTABILITY AND MORE THAN
ADEQUATE ANTICYCLONICALLY CURVED MID/UPPER TROPOSPHERIC WESTERLY
WIND FLOW OVER THE ROCKIES SHOULD SUPPORT ORGANIZED MCS ACTIVITY
ACROSS WESTERN KANSAS AS STORMS INITIATE OVER THE HIGHER
TERRAIN.  THIS PERIOD WILL BE THE BEST OPPORTUNITY FOR NEEDED
RAINFALL IN OUR WESTERN COUNTIES IN A WHILE.

FOR WEEK-2, GIVEN THAT THE WESTERLIES ARE PROBABLE TO SHIFT INTO THE
NORTHERN STATES, I WENT NEAR NORMAL PRECIPITATION WITH ABOVE NORMAL
TEMPERATURES.  I HAD SOME HOPES WE COULD PERSIST THIS FAVORABLE
MCS REGIME A BIT LONGER (THERE IS ALWAYS UNCERTAINTY).  IN FACT,
THERE MAY BE LITTLE RAINFALL FOR PARTICULARLY THE SOUTHWESTERN
COUNTIES WEEK-2 (AND POSSIBLY BEYOND) GOING ALONG WITH 100+ DEG F
MAXIMUM TEMPERATURES.

&&

.AVIATION...

THERE ARE SEVERAL ISSUES FOR THE TAF SITES.  AS I TYPE A COLD FRONT
IS PLUNGING INTO NORTHERN KANSAS WHILE A WEAK LOW-LEVEL CYCLONIC
CIRCULATION EVOLVES ALONG A BOUNDARY SOUTHWEST OF KGCK.  THE FRONTAL
MOVEMENT IS SLOWER THAN I THOUGHT 24 HOURS AGO.  MAIN QUESTION IS
HOW FAR WEST WILL THE SOUTHWARD FORWARD PROPAGATING MCS DEVELOP THIS
AFTERNOON?  SPECIAL 1800 UTC KDDC SOUNDING STILL SHOWS WEAK CAPPING
JUST ABOVE 800MB.  PER WRF IT APPEARS THAT STORMS MAY IMPACT KHYS
BUT STAY EAST OF KDDC, AND THAT SEEMS REASONABLE (WILL MONITOR).
IFR/MVFR CONDITIONS IN THE WAKE OF FRONTAL PASSAGE ARE POSSIBLE
AFTER 0900 UTC MONDAY FOR MAINLY KGCK AND KDDC.
