AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
1043 PM CDT FRI APR 3 2015

.UPDATE...

&&

.AVIATION/06Z TAFS/...

VFR CONDITIONS WILL PREVAIL THROUGH THE DAY SATURDAY AS HIGH
PRESSURE BUILDS INTO THE OHIO RIVER VALLEY. A NEARLY STATIONARY
FRONT WILL SAG A BIT FARTHER SOUTH SATURDAY...BUT REMAIN ACROSS
CENTRAL WISCONSIN. SOME MID LEVEL CLOUDS WILL MOVE ACROSS PORTIONS
OF SOUTHERN WISCONSIN SATURDAY.

&&

.PREV DISCUSSION... /ISSUED 235 PM CDT FRI APR 3 2015/

TONIGHT AND SATURDAY...FORECAST CONFIDENCE...HIGH

CLOUDS WILL EXIT TO THE EAST THIS EVENING...WITH MOSTLY CLEAR SKIES
EXPECTED FOR MUCH OF THE NIGHT. THE COMBINATION OF A COOL/DRY
AIRMASS...LIGHT WINDS...AND THE MOSTLY CLEAR SKIES WILL ALLOW TEMPS
TO DROP TO A FEW DEGREES BELOW NORMAL VALUES FOR EARLY APRIL.

MID LEVEL CLOUDS WILL INCREASE LATE TONIGHT INTO EARLY SATURDAY
MORNING AS A WEAK WAVES PASSES THROUGH. THE CLOUDIEST CONDITIONS
WILL BE IN THE NORTH. SHOULD SEE MOSTLY SUNNY SKIES FOR THE
AFTERNOON THOUGH AS THE WAVE MOVES ON. BUMPED UP HIGHS A BIT FOR
TOMORROW GIVEN WARMING TEMPS ALOFT...THE EXPECTED AFTERNOON
SUNSHINE...AND CONTINUED LOWER RH CONDITIONS.

SATURDAY NIGHT AND SUNDAY...FORECAST CONFIDENCE IS MEDIUM.

HIGH PRESSURE SLIDING OFF TO THE EAST WILL ALLOW A TROF OF LOW
PRESSURE/WARM FRONT TO POKE EAST INTO CENTRAL WI SATURDAY NIGHT.
THE LOW LEVEL JET INTENSIFIES RAPIDLY SOUTH OF THE FRONT...
BRINGING A STRONG SURGE OF WARM AIR ADVECTION AND MOISTURE INTO
THE STATE...IMPINGING ON THE FRONT. THE BEST FORCING AND
SATURATION WILL BE OVER THE NRN HALF OF THE FORECAST AREA...WITH
THE FAR SOUTH/SOUTHWEST FORECAST AREA LIKELY STAYING DRY.

THE FRONT WILL PUSH VERY SLOWLY SOUTH...LOOKING MORE LIKE A
STATIONARY FRONT AS IT DOESN/T MOVE SOUTH OF THE STATE LINE UNTIL
LATER SUNDAY NIGHT. THE TEMP CONTRAST ACROSS THE BOUNDARY WILL BE
SHARP ON SUNDAY WITH THE NE FLOW NORTH OF THE FRONT BRINGING VERY
CHILLY AIR TO THE SHEBOYGAN AREA VS A MUCH WARMER AIR MASS
EXPECTED SOUTHWEST OF MADISON. THE TEMP CONTRAST ACROSS THE
FORECAST AREA COULD BE 20F...MID 40S VS MID 60S. PRECIP CHANCES
ON SUNDAY LOOK VERY LOW AS ALL THE FORCING HAS MOVED OFF...BUT
WILL HANG ONTO A SMALL CHANCE ACROSS THE NE FORECAST AREA.

SUNDAY NIGHT AND MONDAY...FORECAST CONFIDENCE IS MEDIUM.

THE FRONT WILL CONTINUE TO DRIFT FARTHER SOUTH WITH MUCH COOLER
AIR OVERSPREADING ALL OF SOUTHERN WISCONSIN AS EAST TO NORTHEAST
WINDS BECOME MORE ENTRENCHED. SUNDAY NIGHT LOOKS FAIRLY DRY. ON
MONDAY...LOW PRESSURE WILL BEGIN TO DEVELOP OVER THE CENTRAL
PLAINS WITH AN INCREASING LOW LEVEL JET AND ISENTROPIC LIFT ACROSS
THAT FRONT BRINGING INCREASING PRECIP CHANCES BY MONDAY
AFTERNOON. TEMPS MONDAY LOOK QUITE COOL.

MONDAY NIGHT THROUGH WEDNESDAY...FORECAST CONFIDENCE IS MEDIUM.

THE UNSETTLED WEATHER CONTINUES...BUT WE MAY SEE SOME DRYING ON
WEDNESDAY. THAT LOW OVER THE CENTRAL PLAINS WILL SLIDE EAST
THROUGH TUESDAY NIGHT. MONDAY NIGHT THROUGH TUESDAY NIGHT SHOULD
BE PRETTY WET WITH ON AND OFF RAINFALL AS A SERIES OF DISTURBANCES
ROLL THROUGH AND WE CONTINUE TO GET GENTLE UPGLIDE ACROSS THE
FRONT TO THE SOUTH.

HIGH PRESSURE RETURNS ON WEDNESDAY AND SHOULD BE A PERIOD WHERE WE
CAN REMOVE PRECIPITATION CHANCES. TEMPERATURES BY THE MIDDLE TO
END OF NEXT WEEK WILL BOUNCE BACK TO NORMAL LEVELS.

AVIATION/00Z TAFS/...

LOCATIONS NORTHEAST WILL DEAL WITH MVFR CIGS AT TIMES INTO LATE
AFTERNOON...MAYBE EARLY EVENING. THESE LOWER CLOUDS COULD SNEAK
FARTHER SOUTH TOWARD MKE AND ENW...BUT ARE REMAINING SCT FOR NOW.
WILL KEEP AN EYE ON TREND AND UPDATE TAFS IF NEED BE.
OTHERWISE...VFR CONDITIONS WILL PREVAIL THROUGH THE DAY SATURDAY.

MARINE...

WIND GUSTS TO AROUND 25 KNOTS ARE STILL LIKELY THROUGH LATE
AFTERNOON...SO WILL KEEP SMALL CRAFT ADVISORY AS IS WITH 00Z
EXPIRATION.

MAY NEED ANOTHER SMALL CRAFT ADVISORY FROM MID/LATE MORNING THROUGH
LATE AFTERNOON SATURDAY AS A PASSING TROUGH BRINGS GUSTY SOUTHWEST
TO WEST WINDS.

FIRE WEATHER...

ELEVATED FIRE WEATHER CONDITIONS ARE EXPECTED ON SATURDAY ACROSS THE
AREA. SHOULD SEE VERY LOW RELATIVE HUMIDITY VALUES OF 19 TO 28
PERCENT ACROSS MOST OF THE AREA WITH WESTERLY WINDS OF 14 TO 18 MPH.
SOME GUSTS OF 25 TO 30 MPH ARE EXPECTED IN THE AFTERNOON...WITH
ROBUST AND DEEP MIXING. MAY SEE EVEN LOWER RELATIVE HUMIDITY VALUES
INTO THE TEENS IF MIXING IS STRONGER THAN CURRENTLY FORECAST.

IF A FRONT REMAINS FURTHER NORTH THAN CURRENTLY FORECAST ON
SUNDAY...THEN BREEZY SOUTHWEST WINDS WILL USHER IN WARMER
TEMPERATURES AND LOWER RH VALUES FARTHER NORTHEAST INTO THE FORECAST
AREA. BEST CHANCES FOR WARMER/DRIER CONDITIONS WILL BE IN THE
SOUTHWESTERN HALF OF THE AREA. SOME UNCERTAINTY HERE...AS FRONTAL
BOUNDARY POSITION MAY CHANGE.
