.AVIATION /18Z TAFS/...VFR THIS FORECAST PERIOD. SURFACE/850 HIGHS
SLIDE ACROSS AND SLOWLY TO THE EAST. GRADIENT TO RELAX AND EASE

SHORT TERM...
TODAY AND TONIGHT-FORECAST CONFIDENCE MEDIUM
COLD TEMPS IN THE 30S FIGHTING AGAINST LIGHT BOUNDARY LAYER MIXING
IN PATCHY FROST FORMATION ACROSS CWA THIS MRNG. BOUNDARY LAYER WINDS
STILL EXPCD TO BE LIGHTEST IN WEST EARLY THIS MRNG...SO WL CONTINUE
FROST ADVY UNTIL 13Z. PATCHY FROST POSSIBLE EARLY THIS MRNG IN
EASTERN CWA LOW AREAS...WHERE SFC WINDS SLIGHTLY LOWER.
OTRW...STRONG SUBSIDENCE BEHIND VIGOROUS SHORT WAVE EXITING EASTERN
WI EARLY THIS MRNG ALONG WITH LINGERING PARCHED ATMOSPHERE SHOULD
RESULT IN MOSTLY SUNNY DAY WITH CHILLY TEMPS REBOUNDING CLOSE TO AN
AVERAGE OF MAV AND MET NUMBERS. A FEW NORTHERN WI LAKE EFFECT
STRATUS MAY MAKE IT INTO NRN PARTS OF CWA EARLY THIS MRNG.
TEMPS SHOULD DROP OFF RAPIDLY LATE THIS AFTN AND EVENING UNDER CLEAR
SKIES AND LIGHT WINDS. STILL EXPECT HIGH CLOUDS TO INCREASE OVER
PORTIONS OF SOUTHERN WI TONIGHT IN RESPONSE TO WEAK ISENTROPIC
UPGLIDE AND LOWERING CONDENSATION PRESSURE DEFICITS ABOVE
700MB...AHEAD OF WEAK CENTRAL PLAINS SHORT WAVE. HIGH CLOUDS WILL
BE MAJOR PLAYER IN DETERMINING LOW TEMPERATURES TONIGHT. THINKING
TEMPS WILL BEGIN TO LEVEL OFF IN THE UPPER 30S IN SOUTHWEST CWA
AROUND MIDNIGHT...BUT WL CONTINUE TO FALL INTO THE LOW TO MID 30S
ACROSS THE NORTH AND EAST...AWAY FROM LAKE MI. DUE TO LIGHTER
WINDS...WL BEEF UP FROST MENTION...WITH BEST CHANCE IN MY NORTH FROM
WESTFIELD AND PORTAGE EAST TO WEST BEND...INLAND SHEBOYGAN...FOND DU
LAC AND BEAVER DAM. WL LET DAY CREW MAKE FINAL DETERMINATION OF
HIGH CLOUD ARRIVAL...BUT MAY NEED FROST ADVY IN THIS AREA FOR LATE
TNGT.
FRIDAY-FORECAST CONFIDENCE HIGH
UPPER TROUGH CURRENTLY OVER WYOMING HAS 1.5 POTENTIAL VORTICITY
PRESSURE AROUND 400 MB AND IS EXPECTED TO MOVE OUT OF IOWA AND
ALONG THE WISCONSIN/ILLINOIS BORDER DURING THD DAY. DECENT
MOISTURE AND LIFT FROM THIE FEATURE AT MID LEVELS BUT DRY AT LOW
LEVELS AS SURFACE HIGH OVER LOWER MICHIGAN IS SLOW TO RETREAT.
EXPECT PLENTY OF MID AND HIGH CLOUDS BUT IT SHOULD STAY DRY. WITH
850 MB TEMPERATURES AROUND 2C...LAKE INSTABILITY WILL BE RATHER
STRONG WITH WATER TEMP AROUND 20C. GFS DOES HINT AT BRINGING SOME
LAKE EFFECT RAIN SHOWERS ONSHORE IN WEAK SOUTHEAST FLOW REGIME BUT
THIS SEEMS A TAD OVERDONE.
SATURDAY-FORECAST CONFIDENCE HIGH
UPPER RIDGE BUILDS OVER WISCONSIN AHEAD OF APPROACHING TROUGH IN
THE PLAINS. SLOW MOVING POLAR HIGH OVER THE NORTHEAST STATES
SHOULD CONTINUE TO PROVIDE A DRY SOUTHEAST LOW LEVEL FLOW FOR MOST
OF THE PERIOD. LATE SATURDAY NIGHT THE GFS AND GEMNH START TO
BRING WARM ADVECTION PRECIPITATION INTO THE MISSISSIPPI RIVER
VALLEY. CHANCE OF SHOWERS AFTER MIDNIGHT FAR WEST APPEARS
REASONABLE.
LONG TERM...
SUNDAY-FORECAST CONFIDENCE HIGH
MODELS IN GOOD AGREEMENT IN BRING TROUGH AND DEEP MOISTURE INTO
WISCONSIN. FEATURE APPEARS TO BE WEAKENING BUT DECENT COVERAGE OF
PRECIPITATION SHOWN ON GFS AND ECMWF SO RAISED POPS A BIT.
MONDAY-FORECAST CONFIDENCE MEDIUM
USUAL UNCERTAINTY FOR EXTENDED FORECAST STARTS TO CREEP IN AS MOST
OF THE GUIDANCE HAS DRY NORTHWEST FLOW BEHIND THE TROUGH WHILE
GEMNH IS OUTLIER WITH A SLOWER AND DEEPER CLOSED LOW OVER NORTHERN
WISCONSIN. CONSENSUS OF AREA WFOS WAS TO DISREGARD THIS FEATURE
AND LOWER POPS PER GFS AND ECMWF SOLUTIONS. ALSO MAKE ADJUSTMENTS
TO FLOW AND WENT WITH LIGHT NORTHWEST FLOW BEHIND THE SURFACE
TROUGH...AND PER BLEND OF GFS AND ECMWF.
TUESDAY-FORECAST CONFIDENCE MEDIUM
CONSENSUS OF MODEL GUIDANCE HAS ANOTHER TROUGH MOVING THROUGH AND
NOW ALL HAVE A CLOSE LOW MOVING ACROSS WISCONSIN/MINNESOTA/ONTARIO
AREA. ECMWF IS THE DRIEST SOLUTION...WHILE THE GFS AND DGEX ARE
THE WETTEST.
WEDNESDAY-FORECAST CONFIDENCE LOW
YESTERDAY THE ECMWF WAS MOST AGGRESSIVE WITH A DEEP CLOSED LOW
OVER THE MIDWEST. TODAY...THE ECMWF HAS BACKED OFF ON THAT IDEA
BUT THE GFS NOW EMULATES WHAT THE ECMWF DID YESTERDAY. AS IS OFTEN
THE CASE ON DAY 7 FORECASTS...NOT A LOT OF CONFIDENCE.
