AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
1151 AM CDT SUN SEP 23 2012

UPDATED AVIATION PORTION FOR 18Z TAF ISSUANCE

.SYNOPSIS...COOL TODAY AND TONIGHT...THEN WINDY AND WARMER
MONDAY.

LARGE SCALE PATTERN OVER NOAM WAS HIGHLY AMPLIFIED...FEATURING A
LARGE RIDGE IN THE W AND A TROF IN THE E. THE OVERALL TREND WL BE
TOWARD A LESS AMPLIFIED AND MORE PROGRESSIVE PATTERN...THOUGH
ADDITIONAL SHRWVS DROPPING INTO THE ERN TROF WL BRIEFLY REENERGIZE
IT AT TIMES.

THE OVERALL TREND WL BE FOR WARMER TEMPS...BUT IT WON/T BE A
SMOOTH...GRADUAL WARMUP. AFTER ANOTHER COOL DAY AND NGT...TEMPS WL
WARM CONSIDERABLY FOR THE START OF THE WORK WEEK...FOLLOWED BY A
SETBACK MID-WK AS A SHRTWV BRIEFLY RE-ENERGIZES THE LARGE SCALE
TROF. A LONGER-TERM RETURN TO AOA NORMAL TEMPERATURES IS THEN
EXPECTED FOR LATE IN THE WEEK AND NEXT WEEKEND. THE DEVELOPING
ZONAL REGIME WL BE VERY UNFAVORABLE FOR WIDESPREAD SIG PCPN...SO
GENERALLY DRY WX IS EXPECTED.
&&

.SHORT TERM...TDA/TNGT/MON. FROST/FREEZE HEADLINES NOT WORKING OUT
WELL. CLOUDS HOLDING TEMPS UP IN THE N. BUT EVEN WHERE SKIES HAVE
CLEARED...TEMPS NOT FALLING TOO MUCH...WITH 35 F THE COLDEST TEMP
AT 3 AM. NOT GOING TO CARRY THE FROST/FREEZE WORDING IN THE NEW
ZONES ANYWAY...BUT WL PROBABLY OUTRIGHT CANX THE HEADINES IF WE
DON/T GET A TEMP DROP BY 500 AM.

OTHERWISE...QUIETER WX SETTLING INTO THE AREA. LAKE-EFFECT OFF
LAKE SUPERIOR WL LINGER INTO THE MORNING...BUT COME TO AN END AS
THE LOW-LEVEL FLOW BACKS MORE WLY. HAVING COLD UPR TROF STILL
OVERHEAD WOULD SEEM TO SUPPORT AT LEAST ISOLD SHRA THIS AFTN. BUT
RADAR LOOP FM YDA AFTN WAS RATHER UNIMPRESSIVE WITH EVEN MORE
FAVORABLE CONDITIONS. AND GUID INDICATES QG FORCING WL FAVOR
SUBSIDENCE BEHIND A SHRTWV THAT WL BE DEPARTING THE AREA THIS
MORNING. SO OPTED TO STICK WITH DRY FCST FOR THE AFTN.

HAVE ANOTHER POTENTIAL FROST/FREEZE SITN TO DEAL WITH TNGT. THIS
TIME THERE SHOULDN/T BE ANY LOW OR MIDDLE CLDS TO DEAL
WITH...THOUGH SOME CI COULD START STREAMING IN ACRS THE N LATE.
SFC PRESSURE GRADIENT ALSO PROGGED TO TIGHTEN UP FM N-S LATER IN
THE NGT. GIVEN ONGOING HEADLINE...WL SIMPLY ALLOW THE DAY SHIFT TO
POST ANY NEW HEADLINES FOR TNGT. BEST CHC OF HARD FREEZE APPEARS
TO BE IN CENTRAL WI.

STG WAA WL DEVELOP MON AS SFC HIGH PASSES OFF TO THE SE AND COLD
FRONT ASSOCIATED WITH ANOTHER SHRTWV HEADING INTO THE ERN TROF
STARTS DROPPING TOWARD THE AREA. EXPECT BLUSTERY/WINDY
CONDITIONS...BUT WITH TEMPS REBOUNDING SHARPLY FROM THE COOL TEMPS
EXPECTED TDA.

.LONG TERM...MONDAY NIGHT THROUGH NEXT SATURDAY.

A PATTERN CHANGE IS STILL ON TRACK TO OCCUR MID-WEEK...WHEN A
DEEP UPPER TROUGH LIFTS TO THE NE OUT OF THE GREAT LAKES...AND
SPLIT FLOW ENCOMPASSES MUCH OF NORTH AMERICA. MODELS CONTINUE TO
STRUGGLE WITH AGREEMENT AFTER THE PATTERN CHANGE...AS IT SEEMS
LIKE THE STEERING CURRENTS TURN QUITE WEAK WITHIN THE SOUTHERN
BRANCH OF THE SPLIT FLOW. COMPARING GUIDANCE TO ENSEMBLE
DATA...THE 00Z GFS LOOKS LIKE IT HAS A BETTER HANDLE ON THE MASS
FIELDS...SO PREFER A BLEND OF THE 00Z GFS AND GFS ENSEMBLE MEAN.

MONDAY NIGHT THROUGH TUESDAY NIGHT...A SERIES OF SHORTWAVE
TROUGHS WILL SWING ACROSS ONTARIO AND LAKE SUPERIOR OVER THIS
PERIOD...BUT NORTHEAST OF THE REGION. IT WILL HELP HOWEVER TO
REINFORCE THE EASTERN NOAM TROUGH THAT HAS BEEN IN PLACE OVER THE
PAST 5 DAYS OR SO. THE SHORTWAVE MOVING OVER LAKE SUPERIOR MONDAY
NIGHT WILL PUSH A COLD FRONT SOUTHWARD OVER NORTHERN WISCONSIN AND
THEN OVER CENTRAL AND SOUTHERN WISCONSIN ON TUESDAY. WITH DYNAMICS
WELL NE OF THE AREA AND MOISTURE IN LIMITED SUPPLY...NO THREAT FOR
PRECIP. PROGGED SOUNDINGS INDICATE THAT THE ATMOSPHERE WILL
STRUGGLE TO SATURATE ALONG THE FRONT...AND PERHAPS WILL ONLY SEE A
SCT MID-DECK DECK DROPPING SOUTH AT BEST. WILL STICK WITH MOSTLY
CLEAR TO PARTLY CLOUDY CONDITIONS OVER THE PERIOD. LOW TEMPS WILL
BE WARMER MONDAY NIGHT...BUT TEMPS WILL LIKELY COOL DOWN OVER
NORTHERN WISCONSIN ON TUESDAY. CANADIAN HIGH PRESSURE BUILDS INTO
THE AREA TUESDAY NIGHT...BRINGING DOWN ANOTHER DRY COOL AIRMASS.
CLEAR SKIES AND LIGHT WINDS WILL PROMOTE FROSTY NIGHT TIME LOWS
ONCE AGAIN...MAINLY OVER N-C WISCONSIN.

REST OF THE FORECAST...QUIET CONDITIONS LOOK TO CONTINUE THROUGH
THE REST OF THE FORECAST AS THE LATEST INDICATIONS ARE THAT
WISCONSIN WILL RESIDE BETWEEN THE NORTHERN AND SOUTHERN BRANCHES
OF THE SPLIT FLOW. THOUGH WEAK SHORTWAVE ACTIVITY WILL UNDOUBTEDLY
MAKE A RUN AT THE STATE LATE THIS WEEK...MOISTURE LOOKS TIED UP
ALONG A FRONTAL BOUNDARY OVER THE FAR SOUTHERN GREAT LAKES AND
OHIO VALLEY. SO IN THE END...ANY PRECIP CHANCES LOOK PRETTY SMALL.
TEMPERATURES WILL BE SLOWLY WARMING OVER THE PERIOD...WITH HIGHS
MAINLY IN THE UPPER 50S TO MIDDLE 60S. LOWS IN THE 30S AND 40S.
&&

.AVIATION...ISOLATED SHOWERS ACROSS FAR NORTHEAST WISCONSIN WILL END
THIS AFTERNOON. THE CUMULUS CLOUDS (VFR CATEGORY) WILL DISSIPATE AROUND
SUNSET. OTHERWISE...APPROACHING SYSTEM FROM THE NORTHWEST WILL BRING
INCREASING LOW LEVEL WIND SHEAR LATE TONIGHT. WIND SHEAR IS IN THE 18Z
TAFS FROM 09Z TO 14Z. ON MONDAY...IT WILL BE VERY WINDY WITH SOUTHWEST
WINDS INCREASING TO 15 TO 30 KNOTS BY LATE MORNING AND WILL CONTINUE
THROUGH THE AFTERNOON. MOST PLACES WILL SEE GUSTS OF 30 TO 40
KNOTS WITH HIGHEST WIND GUSTS ACROSS NORTHEAST WISCONSIN.
