.SHORT TERM...

A CONTINUOUS FEED OF MOISTURE INTO SOUTHERN WI FUELED STORMS TO
DEVELOP AND REDEVELOP ALONG AN OUTFLOW BOUNDARY...AFFECTING THE
NORTHERN 3/4 OF THE CWA FROM MIDNIGHT THROUGH THE EARLY MORNING
HOURS. FLASH FLOODING OCCURRED IN THE HILLS OF THE WI RIVER VALLEY
AND IN THE URBAN AREAS OF WAUKESHA AND MILWAUKEE COUNTIES. MORE THAN
4 INCHES OF RAIN FELL IN THESE AREAS OVERNIGHT.

AT 0830Z...THE SFC COLD FRONT WAS DRAPED ACROSS THE WESTERN 2/3 OF
WI.

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

THE COLD FRONT WILL CONTINUE TO MARCH ACROSS THE STATE THIS
MORNING...AND EXIT THE FAR SOUTHEAST CORNER OF THE CWA BY MID
AFTERNOON. SHOWERS AND ISOLATED THUNDERSTORMS WILL TAPER OFF AS THE
FRONT PROGRESSES EASTWARD...MOST LIKELY CLEARING THE CWA BY MID
AFTERNOON AS WELL.

TEMPS ARE EXPECTED TO REBOUND QUITE NICELY THIS AFTERNOON...WITH
MOSTLY SUNNY SKIES AND 925MB TEMPS LINGERING IN THE 22 TO 23 DEGREE
RANGE. HIGHS EXPECTED IN THE MID 80S...COOLER NORTH AND WARMER
SOUTH.

QUIET WEATHER EXPECTED TONIGHT WITH HIGH PRESSURE BUILDING INTO THE
REGION.

FRIDAY...FORECAST CONFIDENCE...MEDIUM.

A SFC AND UPPER LEVEL TROUGH EXTENDING FROM THE CLOSED UPPER LOW
OVER ONTARIO WILL CROSS SOUTEHRN WI LATE FRI AFTERNOON INTO SAT
EVENING. MODEL SNDGS SHOW CAPE VALUES IN THE 2000 J/KG RANGE...SO
ADDED SCHC TSRA TO FCST FROM 21Z FRI TO 06Z SAT. NOT A LOT OF
MOISTURE TO WORK WITH...SO CONFIDENCE IS NOT HIGH AT THIS TIME.

QUIET WEATHER EXPECTED AS HIGH PRESSURE BUILDS INTO THE REGION.
LOWER DEWPTS. HIGHS IN THE LOWER 80S.

&&

.AVIATION...THUNDERSTORM OUTFLOW BOUNDARIES WILL COMPLICATE THE
SURFACE WIND FLOW PATTERN THROUGH DAYBREAK. ONE PERSISTENT BOUNDARY
EXTENDS FROM NORTHEAST CORNER OF ILLINOIS TO JUST SOUTH OF MADISON.
THIS BOUNDARY WILL HELP FOCUS STORMS DUE TO WARM SOUTHWEST WINDS AT
3000 TO 5000 FT AGL. DOWNDRAFTS WITH STRONGER THUNDERSTORMS HAVE AND
WILL CONTINUE TO GENERATE SURFACE WIND GUSTS TO 30 TO 40 KNOT RANGE
OUT OF THE NORTHWEST-NORTH. GIVEN AMPLE AMOUNTS OF MOISTURE AHEAD
OF COLD FRONT MOVING ACROSS WISCONSIN...EXPECT MULTIPLE LAYERS OF
CLOUDS WITH CIGS AND VSBYS CHANGING RAPIDLY WITH PASSAGE OF SHOWERS
AND STORMS. VFR CONDS OUTSIDE OF THE SHOWERS AND STORMS ARE
EXPECTED...WITH MVFR TO IFR CONDS WITHIN THE SHOWERS AND STORMS.
BEHIND THE COLD FRONT...EXPECT DAYTIME HEATING OF MOIST GROUND TO
RESULT IN SCATTERED TO BROKEN CIGS OF 3000 TO 5000 AGL. THESE CLOUDS
WILL DISSIPATE BY SUNDOWN THURSDAY.

&&

.MARINE...HIGHLY VARIABLE WEATHER CONDITIONS AND WINDS THROUGH
MID-MORNING THURSDAY DUE TO PERIODS OF SHOWERS AND STORMS. THERE
SHOULD BE ISOLATED POCKETS OF FOG AND LOW STRATUS CLOUDS UNTIL ABOUT
7 AM OR SO. SOME OF THE STORMS WILL GENERATE NORTHWEST TO NORTH WIND
GUSTS TO AROUND 30 KNOTS. OTHERWISE SOUTH TO SOUTHWEST WINDS OF 5 TO
15 KNOTS WILL SWITCH TO WEST TO NORTHWEST AT 5 TO 15 KNOTS BEHIND A
WEAK COLD FRONT WHICH WILL SLOWLY MOVE ACROSS LAKE MICHIGAN
THURSDAY. DO NOT EXPECT SMALL CRAFT ADVISORY CONDITIONS.
