AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
332 AM CDT TUE APR 30 2013

.TODAY AND TONIGHT...FORECAST CONFIDENCE...MEDIUM

STRONG WARM AIR ADVECTION ASSOCIATED WITH 50KT LOW LEVEL JET WILL
CONTINUE TO TRIGGER CONVECTION ACROSS NORTHWEST CWA EARLY THIS
MRNG.  WEAKER WAA FARTHER EAST SO WL CONTINUE SMALLER POPS THROUGH
THE EARLY MORNING AS WELL.  WARM AIR PUSHES RAPIDLY NORTHWARD AS
CAPPING INVERSION BUILDS INTO SOUTHERN WI THIS MRNG INTO THE EARLY
AFTERNOON.  WL TRIM BACK POPS IN SOUTHEAST TO 20 OR LESS.

GUSTY SOUTH WINDS EXPECTED TODAY WITH GUSTS REACHING 30-35KTS LATER
THIS MRNG AND AFTN.

FOCUS OF CONVECTION THIS AFTERNOON AND TONIGHT CLOSE TO APPROACHING
COLD FRONT.  CAPPING INVERSION SHOULD WEAKEN ENOUGH LATER THIS
AFTERNOON AND EVENING TO ALLOW MORE SCATTERED CONVECTION...MOSTLY
NORTHWEST OF MSN.  WEAKENING CAP AIDED BY SLOPING FRONTOGENETICAL
FORCING AND PERIOD OF UPPER LEVEL DIVERGENCE.  HENCE WL KEEP LIKELY
POPS IN WEST DURING THIS PERIOD WITH DIMINISHING TREND OVERNIGHT AS
FOCUS SHIFTS FARTHER NORTHWEST.  PERSISTENT DRY AIR AND WARM MID
LAYERS SHOULD PREVENT OVERNIGHT CONVECTION IN THE FAR SOUTHEAST.

WILL BE THE WARMEST DAY OF THE YEAR TODAY...WITH 925 MB TEMPS
CLIMBING TO AROUND 22C. WILL LIKELY RESULT IN LOW 80S MOST PLACES.
WINDS WILL BE SLOWEST TO GAIN A WESTERLY COMPONENT IN THE
NORTHEAST...SO MAY SEE COOLER HIGHS THERE TOWARD THE LAKE.

.WEDNESDAY...FORECAST CONFIDENCE...MEDIUM

MODELS OVERALL SEEM A BIT SLOWER WITH THE COLD FRONT
WEDNESDAY...KEEPING MILDER AIR ACROSS MUCH OF THE AREA THROUGH THE
DAY. BIGGEST CONCERN IS TEMPS...AS THE FRONT WILL BE CLOSE BY...AND
THERE WILL BE A SHARP DROP-OFF IN HIGHS ON THE OTHER SIDE OF THE
FRONT. FEEL PRETTY CONFIDENT IN WARM TEMPS IN THE SOUTHEAST...BUT
LESS CERTAIN FARTHER NORTH AND WEST. WILL ALSO LIKELY SEE A LAKE
BREEZE DEVELOP...AS WINDS WILL BE LIGHTER THAN ON TUESDAY. THE
TIMING OF WHEN THIS DOES DEVELOP WILL PLAY A PRETTY BIG ROLE IN
HIGH TEMPS EAST AS WELL.

HAVE SOME SMALL POPS WEDNESDAY...AS A MODEL OR TWO SHOW SOME
DEVELOPMENT AS THE COLDER AIR SLOWLY APPROACHES. BULK OF DEEPER
MOISTURE WILL BE NW OF THE FORECAST AREA THOUGH...SO NOT EXPECTING
MUCH PRECIP...IF ANY AT ALL MOST PLACES.

.THURSDAY THROUGH MONDAY...FORECAST CONFIDENCE...LOW TO MEDIUM

THE STORY FOR LATE THIS WEEK INTO EARLY NEXT WEEK CONTINUES TO BE
THE LARGE UPPER LOW THAT WILL MEANDER THROUGH THE REGION. AS IS
OFTEN THE CASE WITH CUTOFF LOWS...MODELS CONTINUE TO STRUGGLE WITH
THE TRACK OF THIS LOW. BY SUNDAY EVENING...THE GFS HAS THE LOW
CENTERED OVER MISSOURI...WITH THE ECMWF PUTTING THE LOW JUST NORTH
OF MINNESOTA...AND THE CANADIAN OVER WEST-CENTRAL WISCONSIN. QUITE
A VARIANCE AMONG MODELS IN TIMING OF PRECIP CHANCES AND TEMPS
THROUGH THIS PERIOD. GENERALLY TRIED TO GO DOWN THE MIDDLE OF THE
ROAD FOR NOW. OVERALL...LOOKS COOLER AND WET THROUGH MUCH OF THE
EXTENDED FORECAST.

&&

.AVIATION/12Z TAFS/...

SCATTERED THUNDERSTORMS EARLY THIS MRNG WILL RAPIDLY DIMINISH AS
STRONG WARM AIR ADVECTION PUSHES NORTH.  BEST CHANCE AT KMSN.
OTHERWISE VFR CONDITIONS EXPECTED FOR BULK OF THIS PERIOD WITH
BREEZY SOUTH WINDS DEVELOPING THIS MRNG.  MORE THUNDERSTORMS WILL
THREATEN MOSTLY THE KMSN AREA LATER THIS AFTERNOON AND EVENING AS
COOL FRONT APPROACHES.

WL PROBABLY USE VCNTY REMARK IN EASTERN TAF SITES OR NO MENTION AS T
CHANCES VERY SMALL AFTER THIS MRNG.

&&

.MARINE...

TIGHTENING PRESSURE GRADIENT ALLOWING GUSTY WINDS TO MIX DOWN TO
SURFACE OVERNIGHT.  HENCE WILL BUMP UP START TIME OF SMALL CRAFT
ADVY TO COINCIDE WITH NEW NEARSHORE FORECAST.  DEWPTS IN THE LOW TO
MID 50S MOVING ACROSS COOL LAKE WATERS WILL LIKELY RESULT IN AT
LEAST PATCHY FOG OVER THE NEARSHORE WATERS TODAY...ESPECIALLY AWAY
FROM THE SHORE.

&&

.MKX WATCHES/WARNINGS/ADVISORIES...
WI...NONE.
LM...SMALL CRAFT ADVISORY UNTIL 7 PM CDT THIS EVENING FOR LMZ643>646.
