AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
339 PM CDT THU APR 29 2010

.DISCUSSION...

DAYS 1-2...

WIND ADVISORY AND POTENTIAL FOR LATE AFTERNOON AND EVENING SEVERE
STORMS ARE THE MAIN FORECAST CONCERNS.

A COLD FRONT HAD MOVED INTO CENTRAL AND PARTS OF SOUTHWEST KANSAS
THIS MORNING AND HAD EFFECTIVELY SHUT OFF THE STRONG WEST
SOUTHWEST WINDS FROM JOHNSON AND SYRACUSE THROUGH GARDEN CITY AND
LARNED. THE BOUNDARY LAYER WAS TRYING TO MIX OUT NEAR THE FRONT
AND WINDS HAD BECOME WESTERLY AND INCREASED AT JOHNSON BUT HAVE
BEEN STAYING WELL BLOW CRITERIA. POINTS FARTHER EAST AND SOUTH
HAVE MIXED OUT AND SUSTAINED WINDS ARE CURRENTLY RUNNING AROUND
26 TO 32 KNOTS. THIS SHOULD CONTINUE UNTIL WE GET NEAR SUNSET.
WILL KEEP THE ADVISORY GOING WHERE THE WINDS ARE CURRENTLY BLOWING
BUT WILL CANCEL IT FOR AREAS TO THE NORTH...GENERALLY FROM JOHNSON
TO GARDEN CITY...JETMORE AND LARNED.

SURFACE DRYLINE WAS CURRENTLY LOCATED FROM NEAR GREAT BEND TO
BETWEEN BUFFALO AND FREEDOM OKLAHOMA. VISIBLE SAT PICTURE SHOWS CU
DEVELOPING ALONG THIS BOUNDARY AS WELL AS THE FRONT FARTHER WEST.
THE FRONTAL CU IS PRETTY FLAT AND HIGH BASED PER LOOK OUTSIDE.
LINE OF CU TO THE EAST OF GREAT BEND APPEARS TO BE GETTING MORE
DEVELOPED. SURFACE MOISTURE AHEAD OF THE DRYLINE IS SOMEWHAT
MODEST AND SOME MID LEVEL WARM TEMPERATURES HAVE A LID ON
CONVECTIVE DEVELOPMENT ACROSS MY EASTERN COUNTIES. MODEL SOUNDINGS
SHOW THIS LID DIMINISHING TOWARD 00Z WITH SOME DECENT INSTABILITY.
DON'T EXPECT A LOT OF DEVELOPMENT IN MY CWA BUT WILL KEEP THE
SMALL POPS FOR THUNDERSTORMS GOING THIS EVENING. STORMS WILL
PROBABLY BE QUICK TO MOVE OUT OF THE CWA AS STRONG WEST SOUTHWEST
FLOW ALOFT CONTINUES OVER THE AREA.

THE NAM AND GFS SHOW PART OF FAR WESTERN KANSAS UNDER THE RIGHT
REAR QUADRANT OF THE UPPER LEVEL JET TONIGHT WITH A VORT MAX
APPROACHING FROM THE SOUTHWEST. MEAN RH VALUES ARE NOT REAL
SATURATED BUT THINK THAT THERE COULD BE ENOUGH MOISTURE AND
FORCING TO WARRANT INCREASED POPS OVER THE WESTERN PART OF THE CWA
OVERNIGHT. THIS SHOULD CONTINUE THROUGH FRIDAY MORNING UNTIL THE
VORT MAX MOVES THROUGH WITH CHANCES DIMINISHING FRIDAY AFTERNOON.

FAIRLY COOL AIR BEHIND THE FRONT WILL BE IN PLACE OVER NEARLY ALL
THE CWA FRIDAY. HIGH TEMPERATURES WILL BE SOME 25 DEGREES UNDER
TODAY'S MAXES.

ANOTHER SHORTWAVE TROUGH/VORT MAX IS FORECAST TO MOVE THROUGH THE
CENTRAL HIGH PLAINS ON SATURDAY. BY THIS TIME THE BEST MID LEVEL
BAROCLINICITY AND JET LEVEL FORCING WILL MAINLY BE JUST SOUTHEAST
OF THE CWA. WILL MAINTAIN SOME 20 PERCENT POPS IN THE SOUTHEAST
CWA AND KEEP SOME VERY SMALL POPS FOR ISOLATED SHOWERS FARTHER
WEST.

DAYS 3-7...

MEDIUM RANGE MODELS HAVE COME INTO SOMEWHAT BETTER AGREEMENT TODAY
IN REGARDS TO THE NEXT FEW SHORTWAVE TROUGHS MOVING INTO THE
PLAINS.  ONE WEAK SHORTWAVE TROUGH WILL BE MOVING ACROSS THE
SOUTHERN PLAINS AT THE START OF THE PERIOD SATURDAY NIGHT, SO WILL
KEEP THE LOW POPS WE HAVE GOING.  ALL OF THE DETERMINISTIC RUNS
START QUICKLY MOVING THE NEXT SHORTWAVE LOBE OF THE MAIN TROUGH INTO
THE ROCKIES SUNDAY AND OUT INTO THE PLAINS BY MONDAY.  THE MODELS
ALSO BRING A WEAK FRONTAL BOUNDARY DOWN ON SUNDAY NIGHT, ALTHOUGH
THERE ARE STILL SOME DIFFERENCES IN EXACT TIMING.  WITH THE
SHORTWAVE TROUGH BEGINNING TO COME OUT AS WELL AS THE BOUNDARY IN
THE AREA, WE SHOULD SEE SOME DECENT CHANCE FOR PRECIP.  ENSEMBLE
PROBABILITIES BEAR THIS OUT, SO WILL BUMP UP POPS FOR SUNDAY NIGHT.
CONDITIONS SHOULD QUIET DOWN AFTER THIS AS NORTHWEST TO WESTERLY
FLOW SETS UP BEHIND THE UPPER SYSTEM AND HIGH PRESSURE BUILDS IN
BEHIND THE FRONT.  HAVE A FEW LINGERING SHOWERS IN THE EAST DURING
THE DAY ON MONDAY, BUT LOWERED POPS FOR MONDAY NIGHT.  TUESDAY
SHOULD SEE NEAR ZONAL FLOW BETWEEN SYSTEMS, AND TODAY THE MODELS ARE
IN MUCH BETTER AGREEMENT WITH BRINGING WARMER AIR IN, WITH 850MB
TEMPS GETTING INTO THE UPPER TEENS TO LOW 20S C.  RAISED TEMPS A FEW
DEGREES.

MODEL AGREEMENT STARTS TO DETERIORATE TOWARDS THE MIDDLE OF NEXT
WEEK.  ALTHOUGH ALL START BRINGING A TROUGH INTO THE PAC NW BY
TUESDAY, THE ECMWF AND CANADIAN ARE MUCH MORE AMPLIFIED, DIGGING
SOME FAIRLY SIGNIFICANT ENERGY FURTHER SOUTH.  THESE MODELS ALSO SET
UP SOME SPLIT FLOW WITH A NORTHERN BRANCH SHORTWAVE HEADING EAST,
BUT VERY WEAK.  THE GFS DOES NOT DIG THE SYSTEM INTO THE WESTERN
CONUS VERY MUCH, BUT BRINGS AN UPPER LOW QUICKLY THROUGH THE
NORTHERN PLAINS WEDNESDAY AND DIGS IT INTO THE GREAT LAKES ON
THURSDAY, LEAVING THE PLAINS IN NORTHWESTERLY FLOW.  THE GFS IS ALSO
MUCH STRONGER ON BRINGING COOLER AIR DOWN ON WEDNESDAY, DROPPING
850MB TEMPS INTO THE SINGLE DIGITS, ALTHOUGH AT LEAST THERE ARE NO
BELOW ZERO READINGS.  THE ENSEMBLE MEANS, INCLUDING BOTH THE NCEP
AND CANADIAN MEMBERS, HAVE MORE TROUGHING IN THE WESTERN CONUS.
THIS FITS WITH THE OPERATIONAL ECMWF AND CANADIAN, SO WILL LEAN MORE
TOWARDS THAT DIRECTION AND BUMP UP TEMPS A BIT FOR
WEDNESDAY/THURSDAY.

&&

.AVIATION...

A FRONTAL BOUNDARY STALLED OUT NEAR KGCK HAS BROUGHT LIGHT WINDS
TO OUR NORTHERN SITES, WHILE KDDC HAS FINALLY STARTED TO PICK UP
OUT OF THE SOUTH. THE BOUNDARY WILL BEGIN TO PUSH NORTHWARD LATE
THIS AFTERNOON, BEFORE PLUNGING SOUTH TONIGHT. THINK THAT FRONT
SHOULD PUSH SOUTH OF KDDC AROUND 02Z OR SO, LEAVING WINDS FROM THE
NORTH AT ABOUT 10-20 KTS. THE NAM HAS SOME STRATUS FORMING JUST
BEHIND THE FRONT TOWARDS TOMORROW MORNING, BUT SEEMS TO BE AN
OUTLIER IN COMPARISON TO THE GFS AND RUC, ALTHOUGH THE SREF HAS
SOME 30-50 PERCENT PROBABILITIES OF CEILINGS LESS THAN 3000 FT.
WILL GO WITH SOME SCT015 FOR NOW, AND HAVE LATER SHIFTS TAKE A
CLOSER LOOK AT IT.
