AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
1200 AM CDT WED OCT 27 2010

...UPDATED AVIATION DISCUSSION...

.DISCUSSION...

SHORT RANGE (TONIGHT-FRIDAY)...

FOCUS FOR THE NEXT FEW DAYS WILL BE ON TEMPERATURES...WINDS...AND
HUMIDITY VALUES. FRONT THAT SWEPT THROUGH THE REGION TUESDAY NIGHT
HAS LEFT THE REGION SUFFICIENTLY VOID OF MOISTURE TO MITIGATE ANY
THREAT FOR RAIN OVER THE NEXT SEVERAL DAYS...LEAVING THE MORE BENIGN
SENSIBLE WEATHER ELEMENTS TO FOCUS ON.

WATER VAPOR IMAGERY SHOWS A LARGE EXTRA-TROPICAL CYCLONE HAS TAKEN
UP TEMPORARY RESIDENCE ACROSS THE WESTERN GREAT LAKES. RESULTING
TIGHT PRESSURE GRADIENT TO THE SOUTH HAS HELP DRIVE THE STRONG WIND
THAT IS PREVAILING ACROSS KANSAS AND MISSOURI TODAY. SCATTERED TO
BROKEN CLOUD COVER ACROSS THE NORTHERN HALF OF THE FORECAST AREA
LOOKS TO BE KEEPING BOUNDARY LAYER MIXING TO A MINIMUM...THUS
PREVENTING WIND ADVISORY CRITERIA FROM BEING MET. HOWEVER...SPEEDS
ARE STILL NEAR ENOUGH TO CRITERIA NEAR THE IOWA BORDER REGION TO
WARRANT KEEPING THE ADVISORY GOING FOR THE REMAINDER OF THE DAYLIGHT
HOURS...THOUGH FARTHER SOUTH THE ISSUE IS A BIT MORE IFFY. WILL BE
TRIMMING OFF THE SOUTHERN HALF OF THE ADVISORY AS A RESULT WITH THE
NEW FORECAST PACKAGE...BUT PLAN TO KEEP AREA NORTH OF A ST JOSEPH TO
MOBERLY LINE GOING. REMAINDER OF THE ADVISORY WILL LIKELY BE CANCEL
BEFORE 7 PM WHEN IT IS DUE TO EXPIRE. LATER SHIFT WILL MAKE THAT
DETERMINATION BASED ON CURRENT OBSERVED WIND SPEEDS.

FOR WEDNESDAY...WINDS ARE EXPECTED TO BE GUSTY AGAIN AS KANSAS AND
MISSOURI WILL STILL BE WITHIN THE SPHERE OF INFLUENCE OF THE TIGHT
PRESSURE GRADIENT SOUTH OF THE MATURE CYCLONE TO OUR NORTH.
HOWEVER...WIND SPEEDS ARE EXPECTED TO BE A LITTLE LOWER THAN
WEDNESDAY AS THE GRADIENT WILL HAVE RELAXED A LITTLE...SO AT THIS
TIME ANOTHER WIND ADVISORY IS NOT EXPECTED. HOWEVER...LOW HUMIDITY
VALUES WILL COMBINE WITH THE GUSTY WINDS TO PRESENT AN ENHANCED FIRE
WEATHER THREAT ACROSS THE ENTIRE REGION WEDNESDAY...SEE FIRE WEATHER
DISCUSSION FOR MORE DETAILS. OTHERWISE...TEMPERATURES ARE EXPECTED
TO ONLY BE MARGINALLY WARMER WEDNESDAY AS COMPETING FORCES WILL BE
FIGHTING OVER SURFACE TEMPERATURES. EXPECTED CLEAR SKIES AND
RESULTING INSOLATION WILL FIGHT WITH COLD AIR ADVECTION ALOFT AS H8
TEMPERATURES WILL BE DROPPING FROM THE MID TO HIGH SINGLE DIGITS INTO
THE LOW AND NEGATIVE SINGLE DIGIT RANGE AS A LOBE OF COOLER AIR
ROTATES UNDER THE LOW WEDNESDAY.

THURSDAY AND FRIDAY...TEMPERATURES WILL GO THROUGH A LITTLE ROLLER
COASTER RIDE AS READINGS DROP SOME THURSDAY...ONLY TO REBOUND FRIDAY.
THURSDAY...IN THE WAKE OF WEDNESDAYS COOL LOBE...TEMPERATURES ALOFT
WILL RESPOND BY RISING...BUT SURFACE WINDS WILL BE FROM THE
NORTHWEST AS A COOL SURFACE HIGH SPREADS ACROSS THE REGION. FRIDAY
OUR REGION WILL BENEFIT FROM BEING ON THE BACK SIDE OF THURSDAYS COOL
SURFACE HIGH...ALLOWING WINDS TO TURN BACK TO THE SOUTH. THIS WILL
ALSO BE THE BEGINNING OF A NICE WARM UP THAT IS EXPECTED TO PERSIST
INTO THE WEEKEND AS THE RIDGE TO THE WEST BEGINS TO TRAVERS THE
PLAINS STATES.

CUTTER

MEDIUM RANGE (FRIDAY NIGHT-TUESDAY)...

WHILE THE MEDIUM RANGE MODELS DO A REASONABLY GOOD JOB HANDLING THE
UPPER SYSTEM CURRENTLY SOUTH OF THE GULF OF ALASKA THEY BEGIN TO
DIVERGE BY THE WEEKEND. GFS DE-AMPLIFIES THE SHORTWAVE AS IT TRACKS
THROUGH CA WHILE THE ECMWF SHOWS A STRONGER YET PROGRESSIVE NATURE
TO THE FEATURE. THE LATEST GEMS HAD EARLIER BEEN MUCH MORE IN LINE
WITH THE ECMWF NOW SLOWS DOWN THE SYSTEM CONSIDERABLY. NONETHELESS
THERE SHOULD BE LITTLE IMPACT TO THE SENSIBLE WEATHER THROUGH
SATURDAY AS PRONOUNCED WARM AIR ADVECTION ANTICIPATED THROUGH H8.
ALL 3 MODELS FORECAST +12C TO +16C TEMPERATURES AT H8 BY 18Z
SATURDAY. SUFFICE IT TO SAY WE ARE LOOKING AT MUCH ABOVE NORMAL
TEMPERATURES. 12Z GFS MAX TEMPERATURES WERE WAY TOO COLD FOR
SATURDAY GIVEN THE EXPECTED H8 TEMPERATURES. SIMILAR TEMPERATURES
WITHIN THE PAST WEEK YIELDED MAX TEMPERATURES IN THE LOWER TO MIDDLE
70S OVER THE WESTERN CWA. EVEN THE CONSENSUS MODEL HAS TOO MUCH
INFLUENCE FROM THE GFS AND CLIMATOLOGY IS PLAYING IS OVER
INFLUENCING TEMPERATURES. HAVE ADJUSTED TEMPERATURES UPWARD
ACCORDINGLY.

GULF OF MEXICO ALSO REMAINS CUT OFF WITH NW FLOW ACROSS THE NORTHERN
GULF INTO TX SO ANY SYSTEM COMING FROM THE PACIFIC VIA CA/CENTRAL
ROCKIES WILL HAVE TO GENERATE CLOUDS/RAIN FROM WHATEVER IT CAN HOLD
ON TO WHILE IS EXITS THE HIGH PLAINS. SO WILL MAINTAIN DRY
FORECAST.

WHILE THE ECMWF AND GFS BOTH AGREE THAT ENERGY WILL DIG SEWD THROUGH
THE ROCKIES THE DIFFER ON THE PROCESS AND TIMING AS WELL AS STRENGTH
OF THE RESULTING TROUGH OR EVEN IF IT CLOSES OFF. WITH AS MUCH
UNCERTAINTY AND LACK OF CONTINUITY WILL NOT ATTEMPT TO INTRODUCE ANY
PRECIPITATION AT THIS TIME AND CONFIDENCE ALSO LACKING WITH RESPECT
TO TEMPERATURES SO WILL DEFER TO CONSENSUS FORECAST WHICH IS CLOSE
TO CLIMATOLOGY.

.FIRE WEATHER...

FOR THE REMAINDER OF THE DAY AND OVERNIGHT HOURS...THE STRONG WEST
WINDS ACROSS THE REGION TODAY WILL BEGIN TO SUBSIDE AS THE SUN
SETS...AND BOUNDARY LAYER MIXING COMES TO AN END. OVERNIGHT WINDS
WILL REMAIN A LITTLE HIGHER THAN AVERAGE AS THEY BACK TO THE
SOUTHWEST...BUT THIS IS DUE TO THE STRONG PRESSURE GRADIENT TO THE
NORTH ASSOCIATED WITH THE LOW IN THE WESTERN GREAT LAKES.

WEDNESDAY...THE GUSTY WEST WIND WILL RETURN TO THE REGION DURING THE
MID-MORNING HOURS AS BOUNDARY LAYER MIXING AND A STRONG PRESSURE
GRADIENT COMBINE ONCE AGAIN. SURFACE WIND SPEEDS ARE EXPECTED TO BE A
LITTLE SLOWER WEDNESDAY THAN TODAYS SPEEDS...BUT HUMIDITY VALUES
COULD BE EVEN LOWER. CURRENT WEST...AND FUTURE SOUTHWEST WIND
OVERNIGHT...WILL BE PULLING AIR FROM A SOURCE REGION THAT IS FAIRLY
VOID OF MOISTURE. THIS COULD ALLOW DEW POINTS TO BOTTOM OUT EVEN
LOWER WEDNESDAY AFTERNOON...ULTIMATELY FLIRTING WITH RED FLAG
CRITERIA. MIDNIGHT SHIFT WILL NEED TO MAKE A DETERMINATION BASED ON
LATEST READINGS AND FORECAST EXPECTATIONS...BUT AT A MINIMUM THERE
WILL BE AN ENHANCED FIRE WEATHER DANGER FOR WEDNESDAY.

CUTTER

.AVIATION...

VFR CONDITIONS EXPECTED THROUGH THE PERIOD. STRONG GRADIENT FLOW
AROUND DEPARTING UPPER MIDWEST POWERHOUSE CYCLONE WILL CONTINUE TO
INFLUENCE THE REGION THROUGH TOMORROW AS MODIFIED CANADIAN AIRMASS
SLOWLY BUILDS ACROSS THE AREA. SOUTHWEST WINDS AROUND 10 KNOTS WILL
INCREASE TO 15 TO 20 KNOTS AFTER 15Z WITH GUSTS APPROACHING /AND
LOCALLY EXCEEDING/ 30 KNOTS DURING THE AFTERNOON -- ESPECIALLY AT
KSTJ. DIRECTION WILL GRADUALLY SHIFT TOWARD THE WEST AND THEN WNW
AFTER 00Z WITH GUSTY WINDS CONTINUING INTO TOMORROW EVENING WITH
SECONDARY COLD FRONT PASSAGE.
