AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
350 AM CDT THU MAR 25 2010

.SHORT TERM...
TODAY...FORECAST CONFIDENCE...HIGH

THIS MORNING...500MB CLOSED LOW OVER THE SOUTH CENTRAL CONUS AND
ASSOCIATED SFC LOW PRODUCING THUNDERSTORMS IN THE GULF STATES AND
WIDESPREAD RAIN IN NORTHERN IL. SFC LOW OVER WESTERN QUEBEC
EXTENDING TROUGH DOWN INTO LOWER MI AND CENTRAL WI. STRONG COLD
FRONT ALONG THIS TROUGH IS PUSHING SOUTHWARD ACROSS NORTHERN LAKE
MI...NORTHERN WI...AND CENTRAL MN AT 830Z THIS MORNING.

THE SYSTEM TO THE SOUTH WILL CONTINUE TO SHIFT SOUTH AND EAST TODAY
AND ASSOCIATED HIGH CLOUDS SPREAD OVER SOUTHERN WI THIS MORNING WILL
GRADUALLY MOVE OUT AS WELL. HI-RES LOCAL WRF AND NAM MODELS RACE THE
COLD FRONT DOWN LAKE MI THIS MORNING...REACHING WINTHROP HARBOR IL
BY 12Z. INLAND WINDS WILL BE A LITTLE SLOWER TO INCREASE. THE
PRESSURE GRADIENT STARTS TO WEAKEN OVER SOUTHERN WI TODAY...WHICH
WILL KEEP WINDS FROM GETTING AS STRONG AS THEY HAVE BEEN AT UPSTREAM
LOCATIONS. STILL...WE SHOULD SEE A QUICK SPIKE IN WINDS WITH GUSTS
TO AROUND 20KT AT INLAND LOCATIONS AS THE FRONT PASSES OVER US.

LAKESHORE COUNTIES WILL STAY PRETTY COOL TODAY...WITH GUSTY NORTH TO
NORTHEAST WINDS OFF THE LAKE. TEMPS WILL BE MUCH COOLER EVERYWHERE
THAN WHAT THEY HAVE BEEN THE PAST WEEK. A FEW LAKE EFFECT CLOUDS ARE
POSSIBLE...MAINLY THROUGH EARLY AFTERNOON...THEN WE SHOULD CLEAR OUT
EVERYWHERE AS A DRY AIR MASS TAKES HOLD.

TONIGHT...FORECAST CONFIDENCE...HIGH

VERY DRY AIR WITH HIGH PRESSURE WILL SEEP OVERHEAD TONIGHT AND ALLOW
FOR CLEAR SKIES AND A COLD NIGHT. PRESSURE GRADIENT WILL BE VERY
WEAK...SO VERY LIGHT WINDS OUT OF THE NORTHEAST ARE EXPECTED.

FRIDAY...FORECAST CONFIDENCE...HIGH

SOUTHERLY WINDS AND SUNNY SKIES WITH RETURN FLOW AROUND THE HIGH ON
FRIDAY. HOWEVER...COOL AND DRY AIR MASS STILL IN PLACE AND SLIGHT
EASTERLY COMPONENT WILL KEEP LAKESHORE AREAS IN THE LOW 40S AND
INLAND LOCATIONS IN THE UPPER 40S TO AROUND 50.

.LONG TERM...
SATURDAY THROUGH MONDAY...FORECAST CONFIDENCE...MEDIUM

850MB TEMPS START TO INCREASE FRI NIGHT AHEAD OF ANOTHER TROUGH
CROSSING THE REGION. A SHORTWAVE ROTATING AROUND THE UPPER LOW NEAR
HUDSON BAY AND ANOTHER CLOSED LOW OVER THE SOUTHERN PLAINS STATES
WILL DRAG A TROUGH ACROSS WI SAT NIGHT INTO SUN. THE BEST FORCING
WILL BE TO THE NORTH AND SOUTH OF THE CWA ONCE AGAIN. THE ECMWF HAS
BEEN VERY CONSISTENT WITH A SLOWER SOLN. HOWEVER...BOTH MODELS SHOW
VERY LITTLE MOISTURE IN SOUTHERN WI. KEPT LOW POPS IN FCST FOR THE
PERIOD.

850MB TEMPS REBOUND FOR A SHORT PERIOD OF TIME ON SAT...SO IT SHOULD
SHAPE UP TO BE A PRETTY NICE DAY. CLOUDY SKIES ON SUN...BUT STILL
ABOVE AVG TEMPS EXPECTED. ECMWF KEEPS EASTERLY FLOW OVER SOUTHERN WI
THROUGH THE FIRST PART OF NEXT WEEK...WHICH WOULD MEAN COOLER TEMPS
BY THE LAKE WOULD CONTINUE. DRY FCST CONTINUES THROUGH EARLY NEXT
WEEK AS HIGH PRESSURE HANGS AROUND.

&&

.AVIATION...A STRONG COLD FRONT OVER NRN WI WILL SURGE SWD EARLY
THIS AM WITH GREATER SWD MOMENTUM OVER LAKE MI. COLD FRONT AND WIND
GUSTS AROUND 30 KTS WILL REACH SE WI TAF SITES BTWN 11Z AND 13Z.
FARTHER INLAND NEAR KMSN...WIND GUSTS AROUND 20 KTS ARE EXPECTED. BY
MID MORNING AFTER INITIAL SURGE OF COLD AIR AND HIGH WIND
GUSTS...WIND GUSTS WILL DECREASE TO 25 KTS FOR TAF SITES IN SE WI
WITH GUSTS TO 18 KTS AT KMSN.

ALONG THE COLD FRONT OVER NE WI AND UPPER MI IS A NARROW BAND OF
MVFR CIGS. BELIEVE FEW-SCT SC CLOUDS WILL PREVAIL THIS AM BUT CANNOT
RULE OUT A BRIEF MVFR CIG DURING THE MORNING HOURS ESPECIALLY OVER
ERN WI. OTHERWISE WINDS WILL DECREASE TNT AND FRI AS HIGH PRESSURE
SHIFTS INTO THE STATE WITH A COLD AND DRY AIRMASS IN PLACE. VFR
CONDITIONS WILL PREVAIL FOR MUCH OF TODAY THROUGH FRI.

&&

.MARINE...A STRONG CANADIAN COLD FRONT OVER NRN WI AND NRN LAKE MI
WILL SURGE RAPIDLY SWD EARLY THIS AM OVER LAKE MI. COLD FRONT AND
WIND GUSTS AROUND 30 KTS WILL SURGE SWD FROM NEAR OR JUST NORTH OF
MANITOWOC AROUND 09Z TO WINTHROP HARBOR IL AROUND 13Z. WILL START
PREVIOUS SMALL CRAFT ADVISORY EARLIER WITH A START TIME OF 10Z.
BRISK NELY WINDS WILL THEN CONTINUE FOR THE REMAINDER OF THE DAY
WITH WAVES REACHING 6-9 FEET THIS AFTERNOON. WINDS WILL DECREASE
THROUGHOUT THE NIGHT BUT HIGH WAVES WILL NOT SUBSIDE BELOW 4 FEET
UNTIL 15Z FRI...WHEN SCA WILL EXPIRE.
