AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
343 PM CDT SAT APR 24 2010

.SHORT TERM...TONIGHT THROUGH SUNDAY. WINDS ARE THE MAIN CONCERN
FOR THIS FORECAST PERIOD AS STRONG SURFACE LOW MOVES FROM MISSOURI
TO INDIANA. GRADIENT IS STRONGEST LATE TONIGHT THROUGH SUNDAY
MORNING. LOW LEVELS COOL AND BECOME MORE UNSTABLE AND CONDUCIVE
TO MECHANICAL MIXING AROUND THAT TIME AS WELL. 925MB WINDS OF 50
KNOTS BY 12Z SHOULD PRODUCE SUSTAINED WINDS OF 25 TO 30 MPH AND
GUSTS TO 45 MPH NEAR LAKE MICHIGAN AND IN THE NORTHERN FOX VALLEY.

SCATTERED SHOWERS IN LOW LEVEL WARM ADVECTION PATTERN SHOULD
DIMINISH THIS EVENING...WITH AN AREA OF STEADY RAINS ARRIVING LATE
TONIGHT IN THE EAST CENTRAL COUNTIES AS LEFT EXIT REGION OF UPPER
JET APPROACHES. THE RAIN SHOULD DIMINISH BY MIDDAY...WITH SOME SUNSHINE
IN THE FAR NORTH AS SOME DRIER AIR ARRIVES LATER IN THE DAY.

.LONG TERM...SUNDAY NIGHT THROUGH NEXT SATURDAY.

LATEST HPC RECOMMENDATIONS LEAN AWAY FROM THE GFS/GFS ENSEMBLE FOR
THE NEXT UPPER TROUGH PROGGED TO SLOWLY MIGRATE ACROSS THE WEST AND
CENTRAL CONUS TOWARDS THE MIDDLE TO END OF NEXT WEEK.  WENT WITH A
BLEND OF THE 00Z ECMWF/GEM THROUGH 00Z FRI TO TRY TO MITIGATE
SMALLER DETAIL DIFFERENCES...WHICH REALLY START TO RAMP UP ON
THURSDAY.  THEREAFTER...TOUGH TO HANG YOUR HAT ON ANY ONE MODEL
SOLUTION...SO TRIED TO BLEND THE GFS/GEM ENSEMBLES.  IN THE
END...CHANGES MADE TO THE FRIDAY/SATURDAY PORTION WERE MINOR.

SUNDAY NIGHT THROUGH MONDAY NIGHT...LOW PRESSURE WILL MOVE ACROSS
THE NORTHERN OHIO VALLEY SUNDAY NIGHT...WITH DECREASING CLOUDS AND
WINDS FROM NORTHWEST TO SOUTHEAST ACROSS THE AREA.  WITH DRIER AIR
MOVING IN FROM THE NE...MODELS PROJECT DRY CONDITIONS SUNDAY EVENING
DESPITE CONTINUED CYCLONIC FLOW.  SHORTWAVE ENERGY THEN DIVES
SOUTHEAST ACROSS THE NORTHERN PLAINS INTO THE MID-MISSISSIPPI VALLEY
MONDAY AND MONDAY NIGHT.  LOTS OF DRY AIR WILL BE PRESENT ACROSS NE
WISCONSIN...THANKS TO CONTINUED NORTHERLY FLOW...SO WILL ONLY SEE
CIRRUS MOVE ACROSS CENTRAL WISCONSIN.  AS A RESULT...DRY CONDITIONS
ARE EXPECTED MONDAY AND MONDAY NIGHT...WITH ONSHORE FLOW KEEPING THE
FOX VALLEY AND LAKESHORE COOLER THAN FARTHER INLAND.  UPPER 50S TO
LOWER 60S LOOK GOOD FOR HIGHS ON MONDAY...COOLER LAKESIDE.   COOL
CONDITIONS MONDAY NIGHT MAKE FROST POSSIBLE SOUTH OF A WAUSAU TO
WAUSAUKEE LINE.  WILL ADD A PATCHY MENTION TO START GETTING THE WORD
OUT.

TUESDAY THROUGH SATURDAY...AS SHORTWAVE ENERGY SLIDES TO OUR SOUTH
ACROSS THE OHIO VALLEY...NORTHERLY FLOW ALOFT WILL PROMOTE HIGH
PRESSURE AT THE SURFACE FOR TUESDAY AND WEDNESDAY.  SHOULD SEE
MOSTLY CLEAR SKIES BOTH DAYS WITH HIGH TEMPERATURES WARMING FROM THE
UPPER 50S TO LOWER 60S ON TUESDAY TO THE MIDDLE 60S ON WEDNESDAY.
WITH THE MOSTLY CLEAR SKIES AND LIGHT WINDS...SOME FROST/FREEZE
HEADLINES MAY BE NEEDED TUESDAY NIGHT. LOW PRESSURE WILL MOVE
INTO THE PLAINS ON WEDNESDAY NIGHT...WITH A WARM FRONT SLOWLY
ADVANCING TO THE NORTHEAST.  WILL LEAVE WEDNESDAY NIGHT DRY...BUT
INTRODUCE LOW CHANCE POPS ON THURSDAY...HIGHEST ACROSS CENTRAL
WISCONSIN.  THE WARM ADVECTION PATTERN CONTINUES INTO FRIDAY WITH
SMALL PRECIP CHANCES.  HARD TO GO DRY ON SATURDAY WITH THE UPPER AND
SURFACE LOWS PARKED TO OUR WEST AND SW FLOW ALOFT...BUT FEEL
COMPELLED TO LET THIS PLAY OUT A LITTLE FIRST.  TEMPERATURES WILL BE
ABOVE NORMAL THURSDAY ONWARD...PENDING CLOUD COVER AND PRECIP.
&&

.AVIATION...STRONG NORTHEAST WINDS MAY CAUSE MECHANICAL TURBULENCE
AND CROSS WIND CONSIDERATIONS AT MTW/SUE/OSH/ATW/GRB LATE TONIGHT
AND SUNDAY. OTHERWISE MVFR AND OCNL IFR CIGS/VSBYS EXPECTED THIS
EVENING IN EAST CENTRAL WISCONSIN WITH POSSIBLE IMPROVING CIGS AND
VSBYS LATE TONIGHT. REST OF THE AREA SHOULD HAVE VFR/MVFR CIGS AND
VSBYS THIS EVENING WITH BRIEF IFR IN CENTRAL WISCONSIN.

.MARINE...GALE WARNINGS ISSUED FOR 09Z THROUGH 21Z.
