AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
300 PM CDT TUE MAR 27 2012

.SHORT TERM...TONIGHT AND WEDNESDAY.

LATEST RUC ANALYSIS AND SATELLITE/RADAR IMAGERY SHOW LOW PRESSURE
MOVING NE OVER FAR NORTHERN MINNESOTA...AND ITS ASSOCIATED COLD
FRONT NOW CROSSING THE MINNESOTA/WISCONSIN BORDER.  NO PRECIP ALONG
THE COLD FRONT SO FAR THROUGH EARLY THIS AFTERNOON WHERE
TEMPERATURES HAVE RISEN INTO THE MIDDLE TO UPPER 60S OVER WESTERN
WISCONSIN.  MUCH COOLER OVER NE WISCONSIN WHERE CLOUD COVER HAS KEPT
TEMPERATURES IN THE 40S AND 50S.  THE BIGGEST STORY SO FAR HAS BEEN
THE GUSTY WINDS...WHICH SEEM TO BE PEAKING ABOUT NOW.  HAVE SEEN
SEVERAL REPORTS ALONG THE LAKESHORE FROM SHEBOYGAN TO SISTER BAY OF
GUSTS TO 45 MPH...AND A FEW REPORTS IN THE 50S AT THE KEWAUNEE AND
ALGOMA MARINE STATIONS.  INLAND LOCATIONS HAVE BEEN CONSISTENTLY
GUSTING BETWEEN 35 AND 40 MPH.  HAVE BEEN TREATING THE STRONG GUSTY
WINDS ALONG THE LAKESHORE AS A LOCALIZED PHENOMENA...AND USING SPS/S
TO HIGHLIGHT THE THREAT.  BEHIND THE FRONT...SEE A PRETTY SOLID
STRATO-CU DECK OVER MINNESOTA AND THE DAKOTAS WITHIN A COLDER
AIRMASS.  FORECAST CONCERNS INCLUDE WIND THROUGH THE EVENING...THEN
CLOUDS AND TEMPS.

TONIGHT...OCCLUDED LOW PRESSURE OVER NORTHERN MINNESOTA WILL TRACK
ENE ACROSS NORTHERN LAKE SUPERIOR TONIGHT.  ASSOCIATED COLD FRONT
WILL DROP ACROSS THE SE 2/3RDS OF THE FORECAST AREA THIS
EVENING...SHIFTING OUR WINDS FROM THE SOUTH TO THE WEST.  WILL
PROBABLY SEE GUSTY WINDS ALONG THE LAKESHORE THROUGH EARLY THIS
EVENING AND SHOULD DIMINISH THEREAFTER ONCE THE FRONT MOVES THROUGH.
AM TEMPTED TO PULL OUT POPS TONIGHT GIVEN A LACK OF INSTABILITY AND
CU OF LITTLE VERTICAL EXTENT UPSTREAM.  WILL WAIT UNTIL THE LAST
MINUTE TO LOOK AT THE LATEST TRENDS BEFORE YANKING POPS OUT.  SHOULD
SEE A PERIOD OF CLEARING WORK ACROSS THE AREA ALONG AND BEHIND THE
FRONT BEFORE WRAP AROUND STRATO-CU DIVES IN FROM NW TO SE.  DEEPER
MOISTURE OVER LAKE SUPERIOR AND THE UPPER PENINSULA COMBINED WITH
UPSLOPE FLOW MAY LEAD TO SCT SHOWER ACTIVITY OVER N-C WISCONSIN AS
THE STRATO-CU WORKS INTO THE AREA.  OTHERWISE...DRY CONDITIONS ARE
EXPECTED ELSEWHERE UNDER COLD ADVECTION.  LOWS RANGING FROM THE
UPPER 30S NORTH TO MIDDLE 40S SOUTH.

WEDNESDAY...CYCLONIC FLOW WILL HANG AROUND WITH NW WINDS COLD
ADVECTING THE ENTIRE DAY.  STEEP LOW LEVEL LAPSE RATES COMBINED WITH
AMPLE MOISTURE UP TO AROUND 800MB SUPPORTS A WIDESPREAD BKN/OVC
STRATO-CU FIELD HANGING AROUND THROUGH THE AFTERNOON.  SCT LIGHT
SHOWER ACTIVITY WILL LIKELY CONTINUE THROUGH AT LEAST THE MORNING
HOURS OVER N-C WISCONSIN.  LOOKED INTO SNOW POSSIBILITIES...BUT
MOISTURE DOES NOT LOOK LIKE IT WILL EXTEND HIGH ENOUGH INTO THE COLD
AIR FOR SNOWFLAKES TO BE INTRODUCED INTO THE CLOUDS.  WITH COLD
ADVECTION AND CLOUD COVER...KNOCKED A DEGREE OR TWO OFF THE HIGH
TEMPS...WHICH WOULD PLACE THEM INTO THE LOWER 40S NORTH TO MIDDLE
50S SOUTH.

.LONG TERM...WEDNESDAY NIGHT THROUGH NEXT TUESDAY.

FROST AND FREEZE POTENTIAL CERTAINLY THERE FOR WEDNESDAY NIGHT AS
SURFACE HIGH DRIFTS BY TO THE NORTH AND UPPER RIDGE APPROACHES
FROM THE NORTHERN PLAINS. RECORD WARMTH EARLIER THIS MONTH HAS
STARTED THE DEVELOPMENT OF SOME VEGETATION WHICH MAY BE THREATENED
BY THIS FROST OR FREEZE.

THEN A RATHER ACTIVE PERIOD OF WEATHER EXPECTED WITH SOME RATHER
ABRUPT SWINGS POSSIBLE LATER THIS WEEK AND EARLY NEXT WEEK AS HIGH
AMPLITUDE NEGATIVELY TILTED TROUGH FORECAST TO LIFT NORTHEAST FROM
THE SOUTHERN AND CENTRAL PLAINS. TWO MUCH WEAKER UPPER TROUGHS
MOVE BY THURSDAY NIGHT AND EARLY FRIDAY AND AGAIN SATURDAY. THESE
SHOULD PRODUCE SOME SHOWERS AND ELEVATED THUNDERSTORMS IN THE
SOUTH AND RAIN OR SNOW SHOWERS IN THE NORTH. UPPER RIDGE SHARPENS
SATURDAY AND SUNDAY AND SHOULD RESULT IN MORE VERY WARM
TEMPERATURES SATURDAY SUNDAY AND MONDAY. A WARM FRONT LIFTING
NORTH SUNDAY COULD BE ACCOMPANIED BY SHOWERS AND THUNDERSTORMS
WITH SOME POSSIBILITY OF MARGINALLY SEVERE HAIL.

DEEPENING SURFACE LOW MOVING FROM THE CENTRAL PLAINS TO NORTHERN
WISCONSIN SHOULD BRING 60F DEW POINTS INTO SOUTHERN WISCONSIN WITH
POSSIBLE SEVERE STORMS AS TRIPLE POINT LOW MOVES ACROSS THE AREA.
THEN SHARPLY COLDER TUESDAY WITH RAIN AND SNOW SHOWERS.
&&

.AVIATION...A SURFACE WARM FRONT WILL LIFT INTO CENTRAL AND
EAST-CENTRAL WISCONSIN THIS AFTERNOON...WHICH WILL BE FOLLOWED
CLOSELY BY THE PASSAGE OF A COLD FRONT LATE THIS AFTERNOON INTO THIS
EVENING.  A PERIOD OF MVFR CIGS IS EXPECTED OVER CENTRAL AND
NORTH-CENTRAL WISCONSIN THROUGH MID-AFTERNOON BEFORE CLEARING WORKS
IN FROM THE WEST.  NOT ANTICIPATING MUCH OF A SHOWER AND
THUNDERSTORM THREAT THIS AFTERNOON...SO REMOVED FROM THE FORECAST.
BEHIND THE COLD FRONT...MVFR CIGS WILL RETURN OVER CENTRAL AND
NORTH-CENTRAL WISCONSIN...AND POSSIBLY INTO NORTHEAST WISCONSIN VERY
LATE TONIGHT OR INTO TOMORROW MORNING.  LEFT CIGS AT LOW END VFR AT
GRB/ATW FOR NOW.  WIND SHEAR WILL CONTINUE TO BE PRESENT TONIGHT
THROUGH SHOULD ABATE BY MORNING.  MVFR CLOUDS TO LAST THROUGH THE
MORNING...BUT SHOULD SEE THEM LIFT IN THE AFTERNOON...POSSIBLY TO
VFR OVER CENTRAL WISCONSIN.

.MARINE...THOUGH STABILITY WILL BE INCREASING LATER THIS
AFTERNOON...STRONG SOUTHEAST TO SOUTH WINDS CONTINUE TO IMPACT THE
LAKESHORE WITH GUSTS MEASURED BETWEEN 45 AND 50 KTS AT KEWAUNEE AND
ALGOMA.  SINCE IMPACTS FROM STABILITY HAVE BEEN NON-EXISTENT SO
FAR...WILL EXTEND THE GALE WARNING THROUGH 03Z AFTER COORDINATION
WITH OFFICES TO THE SOUTH. ONCE THE GALE IS OVER...WINDS WILL SWING
AROUND TO THE WEST BEHIND A COLD FRONT THIS EVENING AND
DIMINISH...THOUGH A SMALL CRAFT ADVISORY WILL BE NEEDED DUE
LINGERING WAVES THROUGH THE REST OF THE NIGHT.
