AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
348 PM CDT THU APR 19 2012

.SHORT TERM...

TONIGHT AND FRIDAY...FORECAST CONFIDENCE MEDIUM TO HIGH

WIDESPREAD RAINFALL EXPECTED TONIGHT ALONG WITH A FEW RUMBLES OF
THUNDER AS LOW PRESSURE SLIDES BY JUST SOUTH OF THE STATE. BIGGEST
ISSUE TONIGHT WILL BE TIMING AND PLACEMENT OF DRY SLOT OVER CENTRAL
IOWA. IT IS BEGINNING TO LOOK LIKE THIS DRY PUNCH MAY GO QUITE A BIT
FARTHER WEST THAN ANTICIPATED...BRING A LULL IN THE PRECIP TO A
LARGE CHUNK OF SRN WI THIS EVENING. WILL HAVE TO MONITOR AND UPDATE
POPS IF THIS TREND CONTINUES. KEPT A SLIGHT CHANCE FOR A SNOW MIX
ACROSS THE NORTH LATE TONIGHT AND INTO EARLY FRIDAY MORNING...AS
TEMPS COLLAPSE ON THE BACK SIDE OF THE LOW. SOUNDINGS DRY OUT PRETTY
QUICK UNDER THE COLD ADVECTION...SO NOT ENTIRELY CONFIDENT IN THIS
MIX.

PRECIP WILL EXIT THE EAST FRIDAY MORNING...WITH LINGERING CLOUDY
SKIES THROUGH MOST OF THE DAY. TEMPS WILL STRUGGLE INTO THE MID AND
UPPER 40S WITH THE CLOUDS AND A COLDER AIRMASS IN PLACE. NORTHERLY
WINDS WILL BE BREEZY AS WELL...WHICH WILL PUT AN EXTRA BITE IN THE
AIR.

FRIDAY NIGHT THROUGH SUNDAY...FORECAST CONFIDENCE MEDIUM

THE SHORTWAVE TROUGH PASSAGE WILL OCCUR EARLY FRIDAY EVENING
FOLLOWED BY CLEARING SKIES AND HIGH PRESSURE. GOOD RADIATIONAL
COOLING WILL OCCUR SO WENT WITH AREAS OF FROST GIVEN LOW TEMPS IN
THE LOWER TO MID 30S.

NWLY FLOW ALOFT WILL PREVAIL FOR THE WEEKEND WITH WEAK SHORTWAVE
TROUGHS WITHIN THE FLOW. SFC LOW PRESSURE OVER THE NRN PLAINS ON
SAT WILL WEAKEN AS IT MOVES INTO THE UPPER MS RIVER VALLEY. THE
WARM ADVECTION AND OVERALL QG LIFT WILL REMAIN TO THE WEST UNTIL
SUNDAY WHEN A SHORTWAVE TROUGH PASSES BUT WILL BE WEAK. LOW POPS
ARE FCST SAT NT OVER SOUTH CENTRAL WI AND OVER THE ENTIRE CWA FOR
SUN. TEMP FORECASTS ARE CHALLENGING GIVEN THE WEAKENING SYSTEM
APPROACHING AND NOT KNOWING HOW MUCH CLOUD COVER WILL DRIFT ACROSS
THE STATE. DID ACCOUNT FOR SOME SUNSHINE DURING THE DAY.

.LONG TERM...

MONDAY THROUGH THURSDAY...FORECAST CONFIDENCE MEDIUM

NW FLOW ALOFT WILL LIKELY CONTINUE FOR MUCH OF NEXT WEEK AS A
LARGE UPPER TROUGH BECOMES ESTABLISHED OVER THE NERN
USA...ALTHOUGH SHOULD WEAKEN SOME BY MID WEEK. SMALL CHANCES OF
RAIN FOR PORTIONS OF THE CWA FOR MONDAY AS WEAK VORTICITY MAXIMUMS
ON THE WEST SIDE OF THE UPPER LOW MAY STILL AFFECT THE REGION. LOW
PRESSURE WILL THEN TRACK FROM THE NRN PLAINS TOWARD THE GREAT
LAKES AND WEAKEN. SLY WINDS AND WARM ADVECTION TO BEGIN TUE AND
CONTINUE INTO THE MIDDLE OF THE WEEK. SMALL CHANCES OF PCPN FOR
TUE NT AND WED WITH THE WARM ADVECTION. MEANWHILE...TEMPS BECOME
MORE MILD TOWARD THE MIDDLE OF THE WEEK.

&&

.AVIATION/00Z TAFS/...

WIDESPREAD RAINFALL NORTH WILL CONTINUE INTO TONIGHT ACROSS SOUTHERN
WISCONSIN...ALONG WITH A RUMBLE OR TWO OF THUNDER. STILL LOOKS LIKE
THERE MAY BE A PERIOD OF DRIER WEATHER IN THE SOUTHEAST THIS EVENING
AND EARLY NIGHT AS A DRY SLOT PUSHES INTO THE AREA.

MVFR TO IFR CONDITIONS EXPECTED INTO TONIGHT...THOUGH SOME BRIEF VFR
POSSIBLE AS THE DRY SLOT MOVES THROUGH. RAIN WILL WIND DOWN FRIDAY
MORNING WITH CONDITIONS SLOWLY IMPROVING INTO THE AFTERNOON AS THE
SFC LOW HEADS EAST OF THE AREA.

&&

.MARINE...

WILL BE ISSUING A SMALL CRAFT ADVISORY FOR AREAS NORTH OF WIND
POINT...AS WAVES OF GREATER THAN 4 FEET EXPECTED THROUGH THE NIGHT
UNDER PERSISTENT GUSTY NORTHEAST WINDS. GUSTS TO 25 KNOTS POSSIBLE
AS WELL. THINK A FEW GUSTS TO 25 KNOTS WILL BE POSSIBLE THROUGH LATE
AFTERNOON...BUT LIGHTER WINDS THEN EXPECTED THROUGH THE EVENING AS
LOW PRESSURE DRAWS NEAR AND THE GRADIENT WEAKENS. NORTHERLY GALE
FORCE GUSTS THEN POSSIBLE LATE TONIGHT AND FRIDAY AS THE PRESSURE
GRADIENT TIGHTENS ON THE BACK SIDE OF THE LOW. WILL THUS BE
UPGRADING THE GALE WATCH TO A WARNING.
