AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
217 PM CDT SAT SEP 22 2012

.SHORT TERM...TONIGHT AND SUNDAY.
COMPLEX FORECAST FOR TONIGHT REGARDING FROST/FREEZE HEADLINES DUE
TO DRIER AIR MOVING INTO THE AREA FROM THE WEST...CLOUD COVER AND
THE POTENTIAL FOR WINDS TO REMAIN UP THROUGH MUCH OF THE NIGHT...
ESPECIALLY ACROSS THE EAST. MODELS ARE PERSISTENT IN ADVECTING
DEW POINTS INTO THE 20S ACROSS MUCH OF THE AREA EXCEPT THE FAR
EAST LATE TONIGHT. THIS SEEMS REASONABLE SINCE DEW POINTS WERE
NOW DROPPING INTO THE 20S ACROSS MINNESOTA.

THE SCATTERED SHOWERS ACROSS THE AREA SHOULD COME TO END ACROSS
MUCH OF THE AREA LATE THIS AFTERNOON OR EARLY THIS EVENING. THE
ONLY EXCEPTION WILL BE ACROSS THE FAR NORTH WHERE LAKE EFFECT RAIN
OR SNOW SHOWERS WILL LINGER INTO SUNDAY MORNING. BASED ON 850MB
FLOW AND CELLULAR NATURE OF THE CLOUD COVER...MOST AREAS WILL
BECOME MOSTLY CLEAR LATER TONIGHT. THE ONLY EXCEPTION WILL BE
ACROSS THE FAR NORTH WHERE SKIES COULD RANGE FROM CLEAR TO
CLOUDY. NUMERICAL GUIDANCE AND THE CANADIAN MODEL ALSO SUGGESTED
THIS SCENARIO WITH CLOUD COVER DECREASING AFTER MIDNIGHT FROM
RHINELANDER TO IRON MOUNTAIN.

AS FOR WINDS...CLEARING SKIES COULD ALLOW FOR WINDS TO DECOUPLE
FOR A PERIOD OF TIME TOWARDS SUNRISE...ESPECIALLY AWAY FROM THE
BAY AND LAKE. WINDS WERE NOT AS STRONG AS EXPECTED THIS AFTERNOON...
THUS SOME CONCERN IS WARRANTED FOR THE LIGHTER WINDS OVERNIGHT.

AS FOR NUMERICAL GUIDANCE...IGNORED THE MET GUIDANCE LOW OF 30 AT
GREEN BAY SINCE IT WAS COLDER THAN WAUSAU AND NEARLY AS COLD AS
RHINELANDER. A HARD FREEZE IS EXPECTED ACROSS PORTIONS OF NORTH
CENTRAL AND CENTRAL WISCONSIN FROM RHINELANDER TO WAUPACA TO
STEVENS POINT AND WISCONSIN RAPIDS. FOR VILAS COUNTY...TOUGH
CALL ON MIN TEMPERATURES TONIGHT. WITH TEMPERATURES ONLY IN THE 40S
THIS AFTERNOON...IT WOULD ONLY TAKE A FEW HOURS OF CLEAR SKIES
TO ALLOW TEMPERATURES TO FALL TO FREEZING. FROM OCONTO AND MARINETTE
COUNTIES SOUTH THROUGH GREEN BAY AND THE FOX CITIES...LOW TEMPERATURES
WILL BE CLOSE TO FREEZING. THE MAIN PROBLEM IN THIS AREA WILL BE WINDS.
WINDS SHOULD REMAIN UP AT 5 TO 10 MPH THROUGH MOST OF THE NIGHT. MAIN
QUESTION HERE IS WILL THERE BE A BRIEF PERIOD OF LIGHT WINDS TOWARD
SUNRISE TO ALLOW FOR FROST TO FORM. DECIDED TO ERROR ON THE SIDE OF
CAUTION AND ISSUE A FROST ADVISORY FOR THIS AREA. FOR THE THREE LAKE
SHORE COUNTIES...WINDS SHOULD REMAIN UP TO PREVENT WIDESPREAD
FROST TO DEVELOP.

ON SUNDAY...SOME LINGERING RAIN OR SNOW SHOWERS ARE EXPECTED
SUNDAY MORNING ACROSS THE FAR NORTH. OUTSIDE THIS AREA...FAIR
WEATHER CUMULUS CLOUDS EXPECTED TO DEVELOP BY LATE MORNING OR
EARLY AFTERNOON. THE GREATEST CONCENTRATION OF CLOUD COVER WILL
BE ACROSS NORTHEAST WISCONSIN. THE CLOUD COVER SHOULD ERODE LATE
SUNDAY AFTERNOON AS DRIER ERODES THE CLOUDS. DID NOT STRAY FAR FROM
GUIDANCE FOR HIGHS ON SUNDAY.

.LONG TERM...SUNDAY NIGHT THROUGH NEXT SATURDAY.

LITTLE CHANGE IN PREVIOUS FORECAST PACKAGE THOUGHTS AS COLD
PATTERN WITH DEEP LONGWAVE TROUGH EXPECTED TO LIFT OFF INTO EASTERN
CANADA BY THE MIDDLE OF NEXT WEEK...WITH A FLATTER SPLIT FLOW
REPLACING IT OVER MUCH OF CONUS. MODELS BEGIN TO DIFFER ON THE
DETAILS OF SYSTEMS MOVING THROUGH FLOW AROUND MIDWEEK...THOUGH
THEY ALL SUGGEST MUCH OF AVAILABLE MOISTURE WILL BE TIED TO FRONT
LOCATED TO OUR SOUTH OVER THE OHIO VALLEY...SO STAYED WITH MAINLY
DRY EXTENDED FORECAST.

SUNDAY NIGHT THROUGH TUESDAY...CANADIAN HIGH PRESSURE WILL
SLIDE TO THE SOUTHEAST TOWARDS THE OHIO VALLEY SUNDAY WHILE A
COLD FRONT WILL DROP SOUTH INTO SOUTHERN MANITOBA AND ONTARIO BY
MONDAY MORNING. LOW LEVEL WINDS INCREASE OVERNIGHT WITH SOUNDINGS
SHOWING WINDS JUST ABOVE THE BOUNDARY LAYER AT 25KTS
SOUTH...CLOSER TO 35KTS OVER THE NORTH. TEMP GUIDANCE FROM MODELS
HAVE TRENDED UP THIS CYCLE. HAVE DONE LIKEWISE...GOING MORE WITH
PATCHY FROST WORDING. COLDEST TEMPS OR FASTER FALL EXPECTED OVER
THE SOUTH WHERE WINDS MAY DECOUPLE BRIEFLY DURING THE EARLY
EVENING.

THE COLD FRONT WILL CONTINUE SOUTH SLOWLY MOVING INTO GRB AREA DAY
PERIOD TUE. LOOK FOR TEMPS WARMING TO NORMAL BOTH MON AND TUE THEN
DROP BACK A BIT FOR THE REST OF THE WORK WEEK. BACKED DOWN A
DEGREE ON TEMPS FROM GUIDANCE FOR MON HIGHS GIVEN STRENGTH OF WINDS
EXPECTED DURING THE DAY.
&&

.AVIATION...SCATTERED SHOWERS WILL GRADUALLY END THIS AFTERNOON OR EARLY
THIS EVENING ACROSS MUCH OF THE AREA. SOME OF THE SHOWERS WILL CONTAIN
SLEET ACROSS THE FAR NORTH. THE ONLY EXCEPTION WILL BE ACROSS THE FAR
NORTH WHERE LAKE EFFECT RAIN OR SNOW SHOWERS WILL LINGER INTO
SUNDAY MORNING. OUTSIDE SOME MVFR CIGS OR VISIBILITIES DUE TO THE
SHOWERS THIS AFTERNOON...VFR CONDITIONS SHOULD PREVAIL EXCEPT FOR
SOME PATCHY MVFR CIGS ACROSS THE FAR NORTH DUE TO LAKE EFFECT RAIN OR
SNOW SHOWERS. NORTHWEST WINDS EXPECTED ON SUNDAY...WITH GUSTS OF
15 TO 20 KNOTS EXPECTED FROM LATE MORNING THROUGH LATE AFTERNOON.
