AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
318 PM CDT MON MAY 28 2012

REST OF THIS AFTERNOON AND TONIGHT - CONFIDENCE...MEDIUM
STRONGEST VORTICITY PUNCH HEADING FROM THE DAKOTAS THROUGH NORTHERN
MINNESOTA INTO CANADA. 500 MILLIBAR PROGS GRADUALLY OOZE THE HEIGHT
FALLS INTO THE NORTHWEST CWA WITH SOME MID/UPPER LEVEL COLD AIR
ADVECTION. OVERALL VORTICITY ADVECTION LOOKS WEAK/CHANNELIZED INTO
NW CWA. STILL SOME DECENT INSTABILITY PARAMETERS PROGGD INTO WRN CWA
THROUGH EARLY EVENING. MID LEVEL LAPSE RATES ARE OK...AROUND 7 PER
MESO PLOTS. DRY SLOT WORKING NORTHEAST FROM IOWA INTO WI. TWO
SEPARATE N/S LINES HAVE POPPED ON THE LEADING EDGE OF THE DRY SLOT
IN WRN WI AND THE FURTHER EAST ACTIVITY HAS WEAKENED CONSIDERABLY.
THE MORE WESTWARD LINE WILL HAVE TO BE WATCHED FOR MOST LIKELY
INTENSIFICATION. NOT CONFIDENT THAT FURTHER WESTWARD DEVELOPMENT
WILL TAKE PLACE WITH BRUNT OF DRY SLOT ACROSS IOWA AND NO REAL UPPER
WAVE OF NOTE TO KICK THINGS OFF. PLUS AS OF 18Z...A DECIDED SHIFT IN
WINDS TO A MORE WESTERLY DIRECTION INTO EXTREME EASTERN IA.
PREFERRED AREA IS USUALLY ALONG THE LEADING EDGE OR NOSE OF DRY
SLOT...SO WE/LL SEE. LOW PRESSURE SHIFTS OFF TO THE NORTHEAST AND
DRAGS COLD FRONT THROUGH EASTERN WI LATER THIS EVENING. WINDS SHIFT
TO THE WEST.

TUESDAY - CONFIDENCE...MEDIUM
STRONG VORT CENTER MOVES FROM NORTHERN MN TO EAST OF LAKE SUPERIOR.
SECONDARY VORT MAX CRUISES INTO CENTRAL WI BY 00Z. 850/925 COLD
ADVECTION WILL BE THE RULE AND BUFKIT SOUNDINGS DO SHOW THE BETTER
MOISTURE FURTHER NORTH. THE MAIN CONCERN MAY END UP BEING THE WIND
WITH DECENT MIXING TAPPING INTO SOME OF THE STRONGER WINDS OFF THE
DECK. POTENTIAL FOR 30-35 KNOT GUSTS.

TUESDAY NIGHT THROUGH THURSDAY...FORECAST CONFIDENCE MEDIUM

A COUPLE WEAK SHORTWAVE TROUGHS WILL MOVE ACROSS WI TUE NIGHT AND
WED IN THE WAKE OF THE STRONG SHORTWAVE TROUGH MOVING EAST ACROSS
SRN CANADA. AT THE SFC...COLD ADVECTION ON NLY WINDS WILL AFFECT THE
AREA INTO WED AM WITH HIGH PRESSURE TO FOLLOW THROUGH WED NT.
ATMOSPHERE WILL BE TOO DRY WITH LITTLE TO NO LIFT SO NO PCPN IS
FORECAST. SOME SUNSHINE EXPECTED ON WED.

FOR WED NT AND THU A 100 KT NWLY JET STREAK AND DIGGING SHORTWAVE
TROUGH WILL MOVE INTO THE GREAT PLAINS. AN INVERTED TROUGH WILL
DEVELOP AT THE SFC WITH CYCLOGENESIS ALONG IT ON THU AS A 1000 MB
SFC LOW MOVES TO THE IL/MO BORDER BY 00Z FRI. THE TRACK OF THE
SYSTEM ALONG WITH DRY AIR OVER WI WILL LIKELY KEEP MOST OF THE CWA
DRY. JUST A SLIGHT CHANCE OF SHOWERS IS FORECAST FOR THE SRN CWA ON
THU. TEMPS WILL REMAIN COOL DURING THIS PERIOD.

LONG TERM...

FRIDAY THROUGH MONDAY...FORECAST CONFIDENCE LOW

EXTENDED MODELS DIVERGE WITH THE TRACK AND EVOLUTION OF THE LOW
PRESSURE AREA THAT WILL BE LOCATED OVER THE MIDDLE MS RIVER VALLEY
THU NT. VARIOUS MODELS TAKE LOW ANYWHERE FROM A NWD TRACK THROUGH
LOWER MI VERSUS MOVING NEWD JUST NORTH OF THE OHIO RIVER VALLEY.
EITHER WAY WILL HAVE TO KEEP RAIN CHANCES IN THE FORECAST THROUGH
SAT. THEN MODELS DIVERGE ON HOW QUICKLY SLY FLOW AND WARM...MOIST
ADVECTION RETURNS TO THE AREA FOR SUN/MON. THUS SMALL POPS ARE
FORECAST AS WELL. COOL TEMPS WILL GRADUALLY WARM WITH ABOVE NORMAL
TEMPS RETURNING EARLY NEXT WEEK.

&&

.AVIATION/00Z TAFS/...WITH COLD FRONT ON THE WAY FOR THIS EVENING
STILL POTENTIAL FOR SHRA/TSRA UNTIL THE FRONT MOVES OFF TO THE
EAST. EXPECTING CEILINGS/VSBYS VFR INTO TUESDAY...THOUGH AN
ISOLATED MVFR CIG/VSBY NOT OUT OF THE QUESTION WITH ANY
CONVECTION. MAIN STORY FOR TUESDAY WILL BE GUSTY WEST
WINDS...POTENTIALLY GUSTING 25 TO 35 KNOTS. MAIN LOW LEVEL CLOUD
SHIELD AND POTENTIAL FOR PRECIP WITH SECONDARY SHORTWAVE LOOKS TO
REMAIN TO THE NORTH.

&&

.MARINE...CURRENT SMALL CRAFT ADVISORY LOOKS GOOD WITH GUSTY
SOUTHWEST WINDS AHEAD OF APPROACHING COLD FRONT. AS TROUGH AXIS
APPROACHES EXPECT WINDS TO SLACKEN FOR A TIME THIS EVENING.
POTENTIAL FOR MORE GUSTY WINDS TUESDAY AS WEST WINDS INCREASE WITH
MIXING. HIGHEST WAVES POTENTIALLY TOWARDS OPEN WATER THOUGH LESS
MIXING FURTHER FROM SHORE MAY LIMIT WAVE ACTION A BIT.
