AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
312 PM CDT TUE APR 17 2012

.TONIGHT AND WEDNESDAY...FORECAST CONFIDENCE...MEDIUM TO HIGH

SKIES WILL START OUT MOSTLY CLEAR THIS EVENING WITH HIGH PRESSURE
CENTERED OVER LAKE HURON. WARM ADVECTION ALOFT WILL RESULT IN
INCREASING MID LEVEL CLOUDS LATER THIS EVENING INTO TONIGHT. WINDS
WILL BE LIGHT THIS EVENING...AND THUS TEMPERATURES WILL FALL QUICKLY
THROUGH THE EVENING WITH THE LACK OF CLOUDS. THE LOWEST TEMPS
TONIGHT WILL BE IN THE EAST WHERE THE WINDS WILL BE LIGHTEST AND
SKIES MOSTLY CLEAR THE LONGEST. TEMPS MAY ACTUALLY HOLD STEADY OR
RISE DURING THE SECOND HALF OF THE NIGHT DUE TO THE WARM ADVECTION
AND CLOUDS.

SHOWERS AND THUNDERSTORMS EXPECTED AHEAD OF AN APPROACHING COLD
FRONT ON WEDNESDAY. RAISED POPS EVEN MORE...AS MODELS ARE SHOWING
ENOUGH LIFT IN Q-VECTOR CONVERGENCE AND FRONTOGENESIS FIELDS TO GO
ALONG WITH PRECIPITABLE WATER VALUES GETTING UP TO AROUND AN INCH.
BEST CHANCE WILL BE ACROSS THE NORTHEAST WHERE THE LIFT WILL BE
GREATEST AND MOISTURE DEEPEST. DECENT WARM SURGE AHEAD OF THE FRONT
UNDER BREEZY SOUTH TO SOUTHWEST WINDS WELL PUSH TEMPS ABOVE NORMAL
INTO THE MID AND UPPER 60S. WARMEST TEMPS WILL BE IN THE SOUTHEAST
WHERE THERE IS A BETTER CHANCE FOR SUNSHINE THROUGH AT LEAST LATE
MORNING.

.WEDNESDAY NIGHT...FORECAST CONFIDENCE IS MEDIUM.
TRAILING COLD FRONT SHOULD BE HANGING ACROSS THE SOUTHERN FORECAST
AREA EARLY...SO WILL KEEP A CHANCE OF SHOWERS IN THE EVENING.
THEN AS THE NEXT SYSTEM ARRIVES QUICKLY FROM THE WEST...THE WARM
AIR ADVECTION OUT AHEAD OF IT MAY SPREAD MORE RAIN INTO AREAS
SOUTHWEST OF MADISON AFTER ABOUT 09Z.

.THURSDAY THROUGH FRIDAY...FORECAST CONFIDENCE IS HIGH.

INTENSE LOW PRESSURE WILL ARRIVE ON THURSDAY WITH A STRONG...VERY
DEEP OMEGA FIELD SUPPORTED BY A DECENT LOW LEVEL JET AND EXCELLENT
UPPER LEVEL EXHAUST SUPPLIED BY THE DIVERGENCE FIELD FROM A
CLASSIC RIGHT REAR ENTRANCE REGION OF THE UPPER JET. THE
ISENTROPIC RESPONSE IS STRONG WITH SATURATION OCCURRING QUICKLY ON
THURSDAY. MIXING RATIOS AT 750MB CLIMB TO 4-6G/KG. THERE IS SOME
CAPE ON THURSDAY THAT MIGHT SUPPORT ISOLATED THUNDER...BUT THIS IS
MAINLY A COOL APRIL RAIN EVENT. TOTAL RAINFALL AMOUNTS IN SOME
AREAS COULD BE ON THE ORDER OF 2 TO 2.5 INCHES. GIVEN THE LONG
TIME FRAME OF WHEN IT FALLS...FLOODING DOESN/T APPEAR TO BE A
CONCERN AT THIS POINT. THE COOLER TEMPS ON THE BACK SIDE OF THE LOW
WILL BE DELAYED A BIT...WHICH PUTS THE CHANCE FOR A RAIN SNOW MIX
ACROSS THE NORTHWEST FORECAST AREA MORE INTO FRIDAY INSTEAD OF
THURSDAY NIGHT.

THE MID LEVEL ENERGY IS BUSY WITH THIS SYSTEM AND LOOKS LIKE IT
WILL HANG UP THIS LOW INTO FRIDAY. SO HAVE HUNG ONTO HIGHER POPS
ON FRIDAY. THE GEMNH AND ECMWF ARE LOOKING MUCH WETTER ON FRIDAY
COMPARED TO THE MORE PROGRESSIVE NAM/GFS.

.FRIDAY NIGHT AND BEYOND...FORECAST CONFIDENCE MEDIUM TO HIGH.

MODELS CONTINUE TO SHOW A QUIET EXTENDED FORECAST FOR THE WEEKEND
INTO EARLY NEXT WEEK AS HIGH PRESSURE MAINTAINS CONTROL. TEMPS
SHOULD BE CLOSE TO NORMAL.

&&

.AVIATION/00Z TAFS/...

VFR CONDITIONS EXPECTED THROUGH TONIGHT. OTHER THAN CUMULUS THROUGH
LATE AFTERNOON...SKIES WILL BE MAINLY FREE OF CLOUDS INTO THIS
EVENING. MID LEVEL CLOUDS WILL LIKELY PUSH INTO THE AREA LATER THIS
EVENING AND INTO TONIGHT DUE TO WARM AIR ADVECTION ALOFT AHEAD OF AN
APPROACHING LOW PRESSURE SYSTEM. THE LOW WILL PASS BY TO THE NORTH
WEDNESDAY...WITH SHOWERS AND THUNDERSTORMS EXPECTED LATE MORNING AND
AFTERNOON. SOUNDINGS SHOW THAT CIGS WILL GENERALLY REMAIN VFR
TOMORROW...BUT MVFR CIGS AND VSBYS CERTAINLY POSSIBLE WITHIN HEAVIER
RAINFALL. EXPECT BREEZY SOUTH TO SOUTHWEST WINDS THROUGH THE DAY
TOMORROW.

&&

.MARINE...

SOUTH TO SOUTHWEST WINDS WILL GUST TO 25 TO 30 KNOTS AHEAD OF AN
APPROACHING COLD FRONT WEDNESDAY. A SMALL CRAFT ADVISORY IS THUS
BEING ISSUED THIS AFTERNOON FOR THE DAYTIME HOURS TOMORROW. THE
HIGHEST WAVES OF 4 TO 6 FEET ARE EXPECTED FROM NORTH POINT LIGHT
HOUSE TO SHEBOYGAN DUE TO THE SOUTHERLY FETCH. WAVES WILL BEGIN TO
DIMINISH DURING THE AFTERNOON AS THE WINDS GAIN MORE OF AN OFFSHORE
COMPONENT.
