AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
1113 AM CDT SUN APR 10 2016

.UPDATE...

FOCUSED WARM AIR ADVECTION AND SOME LOW LEVEL FRONTOGENESIS
RESPONSE HELPING TO DRIVE SHOWERS ACROSS SOUTHERN PORTIONS OF THE
AREA...AS WELL AS POINTS SOUTH AND WEST. MESOSCALE MODELS SUGGEST
THESE SHOWERS WILL CONTINUE AT TIMES THROUGH THE
AFTERNOON...ENDING FROM WEST TO EAST DURING THE EVENING AS A COLD
FRONT PUSHES EASTWARD THROUGH THE AREA. KEPT ISOLATED THUNDER
WORDING THROUGH THE AFTERNOON...AS NAM FORECAST SOUNDINGS INDICATE
WEAK ELEVATED CAPE.

GUSTY SOUTH TO SOUTHEAST WINDS WILL GRADUALLY WEAKEN DURING THE
AFTERNOON...AS THE COLD FRONT APPROACHES AND THE PRESSURE GRADIENT
WEAKENS. CLOUDY SKIES AND THE SHOWERS WILL COUNTER THE WARM AIR
ADVECTION...AS THERE IS AN INVERSION BELOW THE MAIN PUSH OF WARM
AIR. KEPT HIGHS IN THE LOWER TO MID 40S EAST...TO THE LOWER 50S
WEST.

WOOD

.AVIATION/18Z TAFS/...

SHOWERS WILL CONTINUE THIS AFTERNOON INTO EARLY EVENING...ENDING
FROM WEST TO EAST AS A COLD FRONT MOVES THROUGH THE AREA. THERE
WILL BE SOME BREAKS IN THE SHOWER ACTIVITY...ESPECIALLY EARLY THIS
AFTERNOON...WITH MORE ORGANIZED SHOWERS LATER THIS AFTERNOON AND
EARLY EVENING.

THIS MAY DELAY THE DROP OF CEILINGS SEVERAL HOURS...FROM VFR TO
BELOW ALTERNATE MINIMUMS. STILL THINK THIS DROP WILL OCCUR BY
LATER THIS AFTERNOON INTO THIS EVENING...ESPECIALLY TOWARD THE
EASTERN SITES. VISIBILITIES SHOULD REMAIN VFR CATEGORY...WITH SOME
3 MILE VISIBILITIES POSSIBLE IN THE SHOWERS.

SKIES WILL CLEAR OUT LATER TONIGHT...WITH MOSTLY SUNNY SKIES ON
MONDAY. SOME 5000 FOOT DIURNAL CUMULUS CLOUDS ARE POSSIBLE IN THE
LATE MORNING AND AFTERNOON.

THE GUSTY SOUTH TO SOUTHEAST WINDS WILL GRADUALLY WEAKEN THIS
AFTERNOON...AS THE FRONT MOVES TOWARD THE AREA. WINDS WILL VEER
WEST THIS EVENING...AFTER THE FRONT MOVES EAST OF THE AREA. WINDS
WILL REMAIN WESTERLY TONIGHT INTO MONDAY...BECOMING NORTHWEST BY
MONDAY AFTERNOON AND BECOMING GUSTY ONCE AGAIN.

WOOD

.MARINE...

EXPECT GALE FORCE GUSTS TO LINGER INTO THE EARLY AFTERNOON DUE TO
TIGHT PRESSURE GRADIENT AHEAD OF APPROACHING LOW PRESSURE
TROF...AND ENHANCED BY STEEP LOW LEVEL LAPSE RATES. LOW LEVEL
WARMING WILL ERODE LOW LEVEL LAPSE RATES THIS AFTERNOON AND
PRESSURE GRADIENT WEAKENS.

FOR NOW...EXTENDED GALE WARNING UNTIL 20Z AND WL LIKELY NEED TO
BE FOLLOWED BY SMALL CRAFT ADVISORY FOR SEVERAL HOURS AS WINDS AND
WAVES SLOWLY SUBSIDE.

.PREV DISCUSSION... /ISSUED 246 AM CDT SUN APR 10 2016/

TODAY AND TONIGHT...FORECAST CONFIDENCE IS MEDIUM.

SOUTHEAST WISCONSIN IS IN THE RIGHT ENTRANCE REGION OF THE DEPARTING
JET FROM THE EAST COAST SHORTWAVE.  MEANWHILE AN UPPER SHORTWAVE
OVER SOUTH CENTRAL CANADA DROPS INTO THE UPPER MISSISSIPPI VALLEY
THIS EVENING WITH SOUTHERN WISCONSIN AGAIN IN THE ENTRANCE REGION OF
THE UPPER JET ACROSS THE NORTHERN GREAT LAKES. THIS RESULTS IN
PERSISTENT MAINLY WEAK UPPER DIVERGENCE TODAY AND THIS EVENING.
STRONGEST 700 MB UPWARD MOTION WAS OCCURRING EARLY THIS MORNING UNTIL
AROUND SUNRISE.  MODERATE UPWARD MOTION AGAIN OCCURS THIS AFTERNOON
DUE TO THE APPROACHING MID LEVEL TROUGH JUST NORTHWEST OF LAKE
SUPERIOR.

700 MB RH IS SATURATED EARLY THIS MORNING BUT DECREASES LATER THIS
MORNING OVER SOUTH CENTRAL WISCONSIN.  RH INCREASES AGAIN THIS
AFTERNOON BEFORE DRYING FROM THE NORTHWEST THIS EVENING. BY MIDNIGHT
THE DRYING EXTENDS ACROSS SOUTHERN WISCONSIN.

THE LOWER LAYERS BECOME SATURATED THIS MORNING...THEN DRY FROM
THE NORTHWEST TONIGHT.

THE NAM IS THE DRIEST MODEL WITH THE PRECIPITATION.  THE GFS HAS
MORE PRECIPITATION...WITH THE ECMWF IN BETWEEN.  WILL GO WITH THE
CONSENSUS WHICH TRENDS TOWARD THE ECMWF.

AS FAR AS THE WINTER WEATHER ADVISORY GOES WILL LEAVE IT FOR NOW.
THERE IS A STRONG TEMPERATURE GRADIENT AT 850 MB ACROSS THE FORECAST
AREA EARLY THIS MORNING AS THE WARM AIR ADVECTION CONTINUES. SURFACE
TEMPERATURES ARE ALSO RISING SLOWLY. THE GFS STILL HAS ELEVATED CAPE
AROUND 150 JOULES/KG OVER THE SOUTHEAST AT SUNRISE.  THERE IS STILL
AN OPPORTUNITY FOR A BRIEF PERIOD OF SNOW/SLEET AND FREEZING RAIN
SOUTHEAST.  TEMPERATURES WARM ENOUGH BY 8 AM AT THE SURFACE...AND BY
THEN THE WARM LAYER ALOFT WILL DOMINATE SO ALL PRECIPITATION WOULD
BE RAIN EXCEPT FOR SMALL POSSIBILITY OF GRAUPEL MAINLY NORTHEAST
AREAS UNTIL MID MORNING.

THEN PRECIPITATION CHANCES WILL INCREASE AGAIN ALONG THE COLD FRONT
THIS AFTERNOON AND INTO THE EARLY EVENING FAR SOUTHEAST.  TONIGHT
THE DRYING WILL BRING CLEARING SKIES FROM THE NORTHWEST MOST AREAS.

MONDAY - CONFIDENCE...MEDIUM TO HIGH
500 MILLIBAR FLOW PATTERN SHOWS BROAD TROUGH MOVING THROUGH WI
WITH SOME EMBEDDED WAVES THOUGH MOSTLY SHEARED VORT NOTED. SFC LOW
WILL CONTINUE TO SHIFT EAST OF LAKE SUPERIOR WITH DRY NORTHWEST
WINDS. BUFKIT SOUNDINGS SHOW STEEP LOW LEVEL LAPSE RATES WITH WELL
MIXED COLUMN TO AROUND 725 MILLIBARS...SO EXPECTING A RATHER
BREEZY DAY WITH SOME POTENTIAL FOR HIGHER BASED CU. LOTS OF DRY
AIR FURTHER UPSTAIRS. 925 TEMPS SUPPORT TEMPS IN THE 40S.

TUESDAY - CONFIDENCE...HIGH
MID LEVEL TROUGH SHIFTS TO THE ERN LAKES AND ERN US WITH SFC HIGH
BECOMING DOMINANT. LIGHTER WIND REGIME IN PLACE WITH SOME
LINGERING INFLUENCE OF LOW LEVEL THERMAL TROUGH BEING REINFORCED
BY ONSHORE FLOW REGIME ASSOCIATED WITH THE HIGH.

TUESDAY NIGHT AND WEDNESDAY - CONFIDENCE...LOW TO MEDIUM
FAIRLY WEAK SHORTWAVE ARRIVES TUESDAY NIGHT AND PASSES TO OUR EAST
WEDNESDAY MORNING. RENEWED DAVA TAKES HOLD FOR WEDNESDAY AFTERNOON.
THE NAM AND GFS KEEP PRECIP TO OUR NORTH WHILE THE 00Z ECMWF SHOWS
QPF ACROSS PARTS OF THE CWA. WILL KEEP POPS QUIET FOR WITH THIS
BEING FIRST RUN OF ECMWF SHOWING PRECIP IN OUR AREA AND OTHER MODELS
KEEPING PRECIP CONSISTENTLY TO OUR NORTH. ALSO SOUNDINGS FROM THE
NAM AND ESP THE GFS SHOW A LARGE AMOUNT OF DRY AIR TO OVERCOME WITH
BETTER MOISTURE PUSH ASSOC WITH SW 850 JET TO OUR NORTHWEST. SO WILL
OPT TO KEEP DRY FORECAST INTACT THIS PERIOD.

THURSDAY THROUGH SATURDAY - CONFIDENCE...MEDIUM TO HIGH
APPEARS 500 MILLIBAR OMEGA BLOCK SETS UP FOR THE END OF THE WEEK
WITH THE RIDGE AXIS PROGGD TO BE SETTING UP NEAR WI. CENTER OF
SURFACE HIGH IS EXPECTED TO BE CENTERED FROM ERN CANADA RIDGING
THROUGH THE ERN LAKES INTO WI. 925 TEMPS WILL BE SLOWLY MODIFYING
THROUGH THE SINGLE DIGITS CELSIUS THIS PERIOD THOUGH ONSHORE FLOW
IS LIKELY EACH DAY KEEPING AN EAST/WEST GRADIENT IN TEMPS
PREVALENT.

AVIATION/12Z TAFS/...LOOKING FOR MVFR CIGS TO DEVELOP THIS MORNING
AND INTO THIS AFTERNOON. ANY REMAINING WINTRY MIX TO END BY 14Z
AS WARM AIR MOVES INTO THE LOWER LEVELS. PERIODS OF RAIN EXPECTED
THROUGH THE DAY...ENDING FROM NORTHWEST TO SOUTHEAST IN THE LATE
AFTERNOON AND EVENING AS A COLD FRONT PUSHES ACROSS THE STATE WITH
SHOWERS ENDING IN THE FAR SOUTHEAST BY MIDNIGHT.

ALSO WATCH FOR LOW-LEVEL WIND SHEAR AS STRONGEST WINDS IN THE 3 THSD
FT TO 5 THSD FT LAYER MOVE ACROSS SRN WISCONSIN THIS MORNING...BUT
EXPECT SURFACE WINDS TO BE STRONG ENOUGH TO KEEP DIFFERENTIAL BELOW
WIND SHEAR CRITERIA.

SKIES SHOULD CLEAR FROM THE NORTHWEST TONIGHT.

MARINE...STRONG SOUTHEAST WINDS WITH GENERALLY LOW-END GALE FORCE
GUSTS EXPECTED THROUGH MORNING. WINDS WILL EASE BY EARLY AFTERNOON
AS THE SURFACE TROUGH AND COLD FRONT APPROACH BUT THERE WILL BE A
PERIOD OF SMALL CRAFT ADVISORY LEVEL WINDS UNTIL THE SURFACE
TROUGH REACHES THE NEARSHORE WATERS.

WEST WINDS BEHIND THE FRONT WILL CLIMB TOWARD SMALL CRAFT LEVELS ON
MONDAY.
