AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
316 PM CDT WED APR 6 2016

.TONIGHT AND THURSDAY...FORECAST CONFIDENCE...MEDIUM

SURFACE LOW VCNTY SRN LAKE MI WILL CONTINUE TO SHIFT EAST THIS
PERIOD. THIS WILL INCREASE CAA ACROSS SRN WI. SHRA CLIPPING FAR SRN
CWA ON NRN EDGE OF PRIMARY MID LEVEL CIRCULATION ACRS SE IA PER
WATER VAPOR LOOP. THERE IS STILL MORE UPSTREAM VORTICITY TO CONTEND
WITH. MESO MODELS SHOW MORE SHRA SPREADING SEWD INTO SRN WI.
LOW LEVEL THERMAL TROUGH AMPLIFIES AS THE NIGHT GOES ON. COULD SEE
SOME FLAKES MIXING IN WITH ANY SHRA AS THE THE COLDER AIRMASS MOVES
SOUTHWARD INTO THE AREA. CONSENSUS OF THE MODELS KEEPS SOME LIGHT
QPF AROUND THE EASTERN CWA ON THURSDAY DUE TO CLOSER PROXIMITY OF
BETTER 500 MILLIBAR CYCLONIC FLOW REGIME. RATHER CHILLY AIRMASS
ARRIVING WITH 850 TEMPS -5 TO -7C SO SOME SNOWFLAKES POSSIBLE WITH
ANY ADDITIONAL SHRA FROM LATER THIS EVENING THROUGH THURSDAY.

.THURSDAY NIGHT THROUGH SATURDAY...FORECAST CONFIDENCE...MEDIUM

PRECIP CHANCES END THURS NIGHT BEHIND LOW PRESSURE OVER THE EASTERN
GREAT LAKES BUT SOUTHERN WI REMAINS UNDER THE INFLUENCE OF BROAD
CYCLONIC FLOW WITH A MID LEVEL TROUGH AXIS OVER THE EAST GREAT LAKES.
PRECIP CHANCES RETURN FRIDAY ASSOCIATED WITH WEAK LOW TO MID LEVEL
FRONTOGENESIS AND A WEAK SURFACE TROUGH. THE BEST CHANCE IS FRIDAY
AFTERNOON AS A POTENT MID LEVEL SHORTWAVE DROPS THROUGH THE REGION.
PRECIP MAY LINGER THROUGH THE EVENING ASSOCIATED WITH SHEARED
VORTICITY.

NAM IS ON THE WARM SIDE OF GUIDANCE FOR MILWAUKEE AND FAR SOUTHERN
WI. ITS WET BULB TEMPS GET TO JUST ABOVE FREEZING MIDDAY WITH SFC
TEMPS IN THE MID 30S FRIDAY AFTERNOON. MOST OTHER GUIDANCE SUGGESTS
ALL SNOW ACROSS MOST OF THE CWA. SO PRECIP TYPE LOOKS TO BE MAINLYSNOW
EARLY FRIDAY WITH A RAIN AND SNOW MIX FOR MADISON AND MILWAUKEE
SOUTH MIDDAY FRIDAY THEN SNOW FRIDAY EVENING. SOME ACCUMULATION IS
POSSIBLE MAINLY FRIDAY MORNING AND EVENING FOR THE NORTHERN CWA
SINCE DAYTIME TEMPS WILL LIMIT MIDDAY ACCUMULATION.

EXPECT BREEZY NORTHWEST WINDS ON FRIDAY WITH STEEP LAPSE RATES AND
DEEP MIXING TAPPING INTO A 30 KT LOW LEVEL JET.

TEMPS WILL BE CHILLY FOR THIS PERIOD UNDER STRONG NORTHWEST FLOW.
HIGH PRESSURE DOMINATES FOR SATURDAY. 925 TEMPS BOTTOM OUT AROUND -9
TO -10 C SATURDAY MORNING.

.SUNDAY THROUGH TUESDAY...FORECAST CONFIDENCE...MEDIUM

SOUTHWEST FLOW AT SURFACE SETS UP AS LOW PRESSURE APPROACHES FROM
THE SOUTHWEST. PRECIP MAY START AS LIGHT SNOW OR A MIX EARLY SUNDAY
MORNING. THEN RAIN IS LIKELY SUNDAY WITH STRONG WARM AIR AND
MOISTURE ADVECTION. THERE IS ALSO A CHANCE OF THUNDER WITH A FEW
HUNDRED J/KG CAPE ACROSS THE SOUTH SHOWN BY THE GFS. BETTER
INSTABILITY IS OVER IOWA.

WARMER AIR IS SHORT LIVED AS NORTHWEST FLOW SETS UP AGAIN ON MONDAY
WITH FRONTAL PASSAGE BEHIND THE DEPARTING LOW. PRECIP ON MONDAY
DEPENDS ON THE PLACEMENT OF A FRONTAL BOUNDARY SOUTH OF THE STATE.

TEMPERATURES WILL BE MILDER FOR THIS TIME PERIOD. THEN HIGH
PRESSURE BRINGS DRY WEATHER FOR MIDWEEK.

&&

.AVIATION/00Z TAFS/...BROAD SFC LOW ACRS SRN LM SHIFTING INTO LWR MI
AND ERN GRT LAKES THIS PERIOD. INCREASING CAA WITH LINGERING
CYCLONIC FLOW WILL RESULT IN SCT RAIN OR SNOW SHOWERS FROM TIME TO
TIME. BEST CHANCE TONIGHT INTO TOMORROW MORNING. IFR CIGS SHOULD BE
PREVALENT WITH THE CYCLONIC FLOW AND AMPLIFYING LOW LEVEL THERMAL
TROUGH. FLOW REMAINS COOL AND CYCLONIC INTO THURSDAY SO EXPECT MORE
SHRA ACTIVITY THOUGH QPF NOT THAT IMPRESSIVE. EXPECT MVFR CIGS TO BE
MORE PREVALENT ON THURSDAY...THOUGH SOME IFR CIGS IN THE MORNING
POSSIBLE.

&&

.MARINE...SMALL CRAFT ADVISORY HAS BEEN ALLOWED TO EXPIRE.
CONSIDERED ANOTHER ONE WITH GRADUALLY TIGHTENING GRADIENT WITH
INCREASING CAA REGIME IN THE WAKE OF THE DEPARTING LOW CENTER. WILL
HOLD OFF FOR NOW AS CONFIDENCE NOT HIGH ATTM IN SUSTAINED SCA
CONDITIONS.

.MKX WATCHES/WARNINGS/ADVISORIES...
