AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
838 PM CDT THU SEP 17 2015

.UPDATE...
NOT MUCH TIME FOR AN UPDATE DUE TO ONGOING SEVERE WEATHER. TRENDS
SHOULD BE SLOWLY WEAKENING WITH DIURNAL STABILITY KICKING IN.
THAT AREA SOUTHWEST OF MADISON WAS IN A ZONE OF GOOD 850-700MB
WARM AIR ADVECTION ACROSS A STABLE COLD POOL FROM EARLIER
SHOWERS/STORMS. HELICITY VALUES WERE VERY HIGH. MONROE AWOS WAS
EVEN PEGGED AT A SOUTHEAST WIND SUSTAINED 19KTS FOR A TIME. A
CLUSTER OF DISCRETE STORMS WERE ROTATING...SOME SIGNIFICANTLY.
TORNADO WARNINGS WERE ISSUED...BUT AS OF THIS WRITING...NOTHING
WAS CONFIRMED AS A TOUCH DOWN OR DAMAGE. THE COLD FRONT STILL HAS
TO MOVE THROUGH AND THAT WILL OCCUR AFTER MIDNIGHT. BUT
AGAIN...THE INTENSITY OF THE CONVECTION SHOULD BE DIMINISHING
THROUGH THE NIGHT.

&&

.AVIATION/06Z TAFS/...
LOOK FOR MVFR TO IFR CONDITIONS TO DEVELOP AHEAD OF AND JUST
BEHIND THE APPROACHING COLD FRONT TONIGHT INTO FRIDAY MORNING. THE
FRONT SHOULD MOVE THROUGH KMSN AROUND 4-5AM AND KMKE 6-7AM.
CONDITIONS SHOULD IMPROVE TO VFR FOR A TIME FROM LATE MORNING
INTO THE AFTERNOON...BUT CONDITIONS ARE EXPECTED TO DETERIORATE
RAPIDLY FRIDAY AFTERNOON INTO FRIDAY NIGHT AS A LOW PRESSURE
SYSTEM MOVES NORTHEAST ALONG THE STALLED COLD FRONT TO OUR SOUTH.

&&

.PREV DISCUSSION... /ISSUED 335 PM CDT THU SEP 17 2015/

LATE THIS AFTERNOON... FORECAST CONFIDENCE MEDIUM.

A LINE OF THUNDERSTORMS IS CROSSING SOUTHERN WI AND NORTHERN IL THIS
AFTERNOON. IT IS ASSOCIATED WITH A MID LEVEL SHORTWAVE CROSSING THE
STATE... WARM AIR ADVECTION... LOW LEVEL JET AND MOISTURE TRANSPORT
OVER THE REGION. THE LINE IS HEADING INTO AN AREA OF HIGHER
INSTABILITY AND BETTER SHEAR DUE TO BETTER DAYTIME HEATING WITH
FEWER CLOUDS OVERHEAD TODAY. WITH TEMPS IN THE LOWER 80S AND
DEWPOINTS IN THE MID TO UPPER 60S... CAPE VALUES ARE IN THE 1000 TO
1200 J/KG RANGE AND 0-6KM SHEAR IS AROUND 30 KT. THESE VALUES
SUPPORT A RISK FOR SOME HIGH WIND GUSTS AND AN ISOLATED HAIL THREAT
SO WE ARE KEEPING A CLOSE EYE ON THE CONVECTION.

SHOWERS AND THUNDERSTORMS ENTERING SOUTHWEST WI ARE IN AN AREA
ALREADY WORKED OVER BY EARLIER CONVECTION TODAY AND ARE NOT EXPECTED
TO BECOME STRONG AS THEY SPREAD EAST THROUGH EARLY EVENING.

TONIGHT... FORECAST CONFIDENCE MEDIUM.

THE COLD FRONT IS LOCATED OVER NORTHEAST AND CENTRAL MN AS OF 3 PM
THIS AFTERNOON. IT WILL REACH SOUTH CENTRAL WI BETWEEN 09Z AND 12Z
/4-7 AM/ EARLY SATURDAY MORNING. THERE IS CONVECTION GOING ON ALONG
IT AND AHEAD OF IT. SOUTHERN WI CAN EXPECT SCATTERED SHOWERS AND
THUNDERSTORMS TO DEVELOP ASSOCIATED WITH CONTINUOUS WARM AIR
ADVECTION... MOISTURE TRANSPORT AND THE NOSE OF THE LOW LEVEL JET
THROUGH LATE EVENING. NOT SURE ABOUT WHERE EXACTLY THESE WILL
DEVELOP AND IF THEY WILL BE ABLE TO BECOME STRONG OR NOT. THE
CURRENT CONVECTION IS PUTTING A DENT INTO THE CAPE AND ADDING CIN...
AND I AM NOT SURE IF WE WILL HAVE TIME TO RECOVER BEFORE STORMS GO
ELEVATED. THUS... SPC KEPT US IN THE SLIGHT RISK FOR SEVERE FROM
MADISON AND WEST FOR TONIGHT.

THERE IS A CHANCE FOR SHOWERS AND THUNDERSTORMS RIGHT ALONG THE COLD
FRONT AS IT CROSSES SOUTHERN WI LATE TONIGHT.

FRIDAY... FORECAST CONFIDENCE MEDIUM.

EXPECT LOW CLOUDS AND MAYBE A FEW SHOWERS TO LINGER ACROSS SOUTHERN
WI FRIDAY MORNING. SHOWERS AND A FEW THUNDERSTORMS ARE POSSIBLE WITH
LINGERING INSTABILITY LINGERING THROUGH FRIDAY AFTERNOON...
DEPENDING ON HOW MUCH SUNSHINE CAN BREAK THROUGH THE CLOUDS. WINDS
WILL BE LIGHT AND THERE MAY BE AREAS OF FOG FRIDAY MORNING.

FRIDAY NIGHT - CONFIDENCE...MEDIUM
CONTINUING THE IDEA OF A HIGH POP SCENARIO WITH SURFACE/850 WAVE
MOVING ALONG 850/925 BAROCLINIC ZONE. MID LEVEL SHORTWAVE ARRIVES
WITH DECENT CVA COMING INTO PLAY AS THE EVENING AND OVERNIGHT
HOURS WEAR ON. MORE OF A DEF ZONE SETUP. 850 FRONTOGENETICAL
FORCING LOOKS PRETTY STRONG ALONG WITH A FAIR AMOUNT OF 700-300
MILLIBAR Q-VECTOR CONVERGENCE. 06Z NAM HAD REALLY INTENSIFIED
SURFACE LOW WITH LARGE QPF DEF ZONE ACROSS WI. THE 12Z NAM HAS
TEMPERED THE 6Z RUN SOMEWHAT BUT IDEA OF A WIDESPREAD RAINFALL
EVENT STILL THERE. SO WILL KEEP THE VERY HIGH POPS GOING.

SATURDAY - CONFIDENCE...MEDIUM
MID LEVEL SHORTWAVE SHIFTS EAST INTO THE EASTERN LAKES WITH
APPRECIABLE AVA WORKING INTO SRN WI. WILL CONFINE ANY LINGERING
SHRA TO THE EARLY MORNING HRS WITH MOS/RH PROGS SHOWING CLEARING
SKIES TAKING HOLD WITH TIME. LOW LEVEL THERMAL TROUGH MOST
PRONOUNCED IN THE MORNING WITH SOME MODIFICATION NOTED INTO THE
AFTN HRS.

SUNDAY THROUGH WEDNESDAY - CONFIDENCE...MEDIUM
LOOKS LIKE A QUIET AND OVERALL SEASONAL PERIOD WITH A FAIRLY
LARGE AREA OF HIGH PRESSURE INFLUENCING THE CONDITIONS. MID LEVEL
FLOW BECOMES CYCLONIC AGAIN SUNDAY AND SUNDAY NIGHT THOUGH BOTH
THE NAM AND GFS SHOW A NEARLY PARCHED COLUMN SO WILL LEAVE THE
QUIET SUPERBLEND POPS ESSENTIALLY AS IS. 500 MILLIBAR HEIGHTS THEN
BUILD AGAIN INTO MID WEEK. 925 TEMPS START TO CLIMB BACK UP AGAIN
THROUGH THE TEENS CELSIUS TUESDAY INTO WEDNESDAY.

THURSDAY - CONFIDENCE...LOW
THE GFS BREAKS DOWN THE MID LEVEL RIDGE WITH SOME SHORTWAVE
ENERGY WHILE THE ECMWF HANGS ONTO A MORE BROAD SW ANTICYCLONIC
FLOW WITH ANY SHORTWAVE ACTIVITY STILL WELL TO THE WEST. FOR NOW
THE SUPERBLEND POPS ARE MORE REFLECTIVE OF THE MORE PROGRESSIVE
GFS SOLUTION.

AVIATION/00Z TAFS/...SHOWERS AND THUNDERSTORMS TRACKING ACROSS
SOUTHERN WI AS OF 3 PM MAY PRODUCE WIND GUSTS UP TO 35 KT BUT
THEY ARE SHOWING SIGNS OF WEAKENING. THERE IS A CHANCE FOR
THUNDERSTORMS THROUGH THE EVENING.

A COLD FRONT WILL TRACK SOUTHEAST THROUGH WISCONSIN TONIGHT.
THUNDERSTORM CHANCES INCREASE JUST AHEAD OF THE FRONT IN SOUTH
CENTRAL WI THIS EVENING AND ARE EXPECTED ALONG THE FRONT OVERNIGHT.
MVFR CIGS AND VSBYS ARE ANTICIPATED FRIDAY MORNING AS THE SHOWERS
DIMINISH DUE TO THE COLD AIR ADVECTION BEHIND THE FRONT.

SHOWERS AND MAYBE THUNDER ARE POSSIBLE DURING THE DAY FRIDAY... BUT
WE EXPECT ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS FRIDAY NIGHT
AHEAD OF ANOTHER COLD FRONT.

MARINE...SOUTH WINDS OF 10 TO 20 KNOTS WITH GUSTS TO 25 KNOTS
NORTH OF PORT WASHINGTON WILL DIMINISH THIS EVENING. WINDS AND
WAVES REMAIN MARGINAL SOUTH OF PORT WASHINGTON. THUNDERSTORMS ARE
EXPECTED IN THE NEARSHORE WATERS BY LATE AFTERNOON AND AGAIN
TONIGHT AHEAD OF A COLD FRONT. SOME STORMS COULD PRODUCE STRONG
WIND GUSTS AND HAIL.

WINDS WILL BE LIGHTER ON FRIDAY. THEY WILL BECOME NORTHEAST IN THE
AFTERNOON. THEN A STRONG COLD FRONT WILL DROP SOUTH THROUGH LAKE
MICHIGAN EARLY SATURDAY MORNING. NORTH GALE FORCE GUSTS COULD
ACCOMPANY THE FRONT. THE MODELS VARY ON THE WIND SPEEDS WITH THIS
SYSTEM... SO WILL HOLD OFF ON A GALE WATCH AT THIS TIME.

BEACHES...WITH SOUTH WINDS OF 15 TO 25 KNOTS AND WAVES OF 3 TO 5
FEET...A BEACH HAZARD STATEMENT FOR THE BEACHES OF SHEBOYGAN COUNTY
LINES UP WITH THE SMALL CRAFT ADVISORY IN EFFECT. HAZARDOUS CONDITIONS
WILL LINGER INTO THE EVENING BEFORE WINDS AND WAVES LOWER. A MODERATE
SWIM RISK EXISTS AT THE LAKE MICHIGAN BEACHES FROM OZAUKEE COUNTY
SOUTH THROUGH KENOSHA COUNTY THROUGH EARLY EVENING.

A STRONG COLD FRONT WILL DROP SOUTH THROUGH LAKE MICHIGAN EARLY
SATURDAY MORNING. NORTH WIND GUSTS OF 40 MPH OR HIGHER COULD
ACCOMPANY THE FRONT AND CAUSE HIGH WAVES AND DANGEROUS CURRENTS. A
BEACH HAZARDS STATEMENT MAY BE NEEDED.

&&

.MKX WATCHES/WARNINGS/ADVISORIES...
WI...BEACH HAZARDS STATEMENT UNTIL 10 PM CDT THIS EVENING FOR WIZ052.
