AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
608 PM CDT WED MAR 23 2011

.UPDATE...WILL SEND OUT UPDATE AT 7PM...CANC HEADLINES. WILL
ISSUE SPS TO HIGHLIGHT LINGERING LIGHT SNOW AND BLOWING INSTEAD OF
ISSUING AN ADVISORY FOR SOUTHEAST ZONES FOR 1 OR 2 MORE HOURS
UNTIL WINDS BACK DOWN. LINGERING BAND OF SNOW TO BE OUT OF AREA
AND OVER LAKE AROUND 8PM.

TE
&&

.PREV DISCUSSION...ISSUED AT 249 PM CDT WED MAR 23 2011...

SHORT TERM...TNGT AND THU. MAIN FCST CONCERNS CENTER AROUND THE
SNOW'S DEMISE THIS EVENING...MIN TEMPS TNGT AS SKIES ATTEMPT TO GO
PARTLY CLDY AND WINDS DIMINISH AND MAX TEMPS ON THU WITH NEW SNOW
COVER.

THE 19Z MSAS SFC ANALYSIS SHOWED A DOUBLE-BARRELED AREA OF LOW
PRES OVER SE INDIANA AND ERN OHIO. AN AREA OF HI PRES EXTENDED
FROM THE CNTRL PLAINS NWD TO THE CANADIAN PRAIRIE. THE LATEST
WATER VAPOR SATL IMAGERY INDICATED AN UPR LOW MOVING ACROSS SRN WI
AND THIS SYSTEM WAS MAINLY RESPONSIBLE FOR THE AFTERNOON SNOW OVER
THE FCST AREA. LATEST RADAR MOSAIC HAD THE BACK EDGE OF THE SNOW
OVER FAR NRN WI WITH A SLOW SAG TO THE SOUTH.

SNOW WL CONT TO PULL AWAY FROM NORTH TO SOUTH THIS EVENING AS THE
UPR LOW PUSHES TOWARD THE ERN GREAT LKS AND WEAKENS WITH TIME.
BASED ON WHERE THE BACK EDGE OF THE PCPN IS LOCATED...WL DROP THE
WINTER STORM WARNING FOR NRN WI BY 21Z. OTHERWISE...HAVE LEFT THE
HEADLINES ALONE FOR CNTRL/E-CNTRL WI TIL 00Z THU AS SNOW STILL IS
FALLING AND GUSTY E-NE WINDS TO PERSIST. SNOW ACCUMULATIONS EARLY
THIS EVENING TO REMAIN LESS THAN AN INCH WITH THE STG WINDS
STARTING TO DIMINISH. DURING THE OVERNIGHT HOURS...HI PRES IS FCST
TO BEGIN BUILDING INTO WI FROM THE UPR MS VALLEY AND START TO
USHER DRIER AIR INTO THE FCST AREA. EXPECT TO SEE SOME BREAKS IN
THE CLDS DVLP AFT MIDNGT AND HAVE GONE FOR PARTLY CLDY SKIES LATE
IN THE FCST. IF SKIES CAN CLEAR OUT FAST ENUF WITH THE DIMINISHING
WINDS AND NEW SNOWPACK...TEMPS COULD PLUNGE TNGT. BELIEVE THERE WL
BE ENUF BNDRY LAYER WIND TO KEEP READINGS FROM FREE-FALLING...
NONETHELESS SINGLE DIGITS AND TEENS ARE ANTICIPATED.

THE HI PRES MOVES INTO THE WRN GREAT LKS RGN ON THU AND BRING A
MOST WELCOME QUIET WEATHER DAY TO NE WI. THE AIR ALOFT IS QUITE
CHILLY FOR LATE MARCH STANDARDS (8H TEMPS AROUND -12C)...THUS MAX
TEMPS TO ONLY REACH THE MID TO UPR 20S UNDER PARTLY CLDY SKIES.

LONG TERM...THURSDAY NIGHT THRU NEXT WEDNESDAY.

A QUIET PERIOD OF WEATHER IS EXPECTED FOR MUCH OF THE LONG TERM
PERIOD AS CANADIAN HIGH PRESSURE SLOWLY SHIFTS SOUTHWARD FROM
HUDSON BAY ON FRIDAY...TO THE WESTERN GREAT LAKES BY TUESDAY.
NORTH WINDS CROSSING LATE SUPERIOR WILL BRING SOME LAKE EFFECT
CLOUDS...OR EVEN SOME FLURRIES TO NORTHERN WISCONSIN...BUT DRY AIR
WILL LIMIT EXTENT AND COVERAGE OF ANY ACTIVITY...KEEPING IT MAINLY
ACROSS UPPER MICHIGAN. AN UPPER LEVEL TROF WILL SWING THRU THE
REGION LATE THIS WEEKEND...HOWEVER DRY SURFACE HIGH PRESSURE
SHOULD KEEP THE AREA DRY.

WILL NEED TO KEEP AN EYE ON THE SOUTHERN STREAM SYSTEM TAKING
SHAPE EARLY NEXT WEEK...AS IT IS FORECAST TO MOVE TOWARD THE OHIO
VALLEY BY TUESDAY. MODEL GUIDANCE KEEPS ALL THE PRECIP ASSOCIATED
WITH THIS SYSTEM SOUTHEAST OF THE AREA...BUT ANY SHIFT TO THE
NORTHWEST WILL BRING A PRECIP INTO THE AREA.

TEMPERATURES ARE EXPECTED TO REMAIN MAINLY BELOW NORMAL THRU THE
PERIOD WITH COLD AIR FILTERING IN FROM CANADA. NEW/FRESH SNOWPACK
WILL ALLOW TEMPS TO FALL INTO THE SINGLE DIGITS AT NIGHT...WITH
SOME BELOW ZERO READINGS POSSIBLE ACROSS N/C WI LATE THIS WEEK AND
THIS WEEKEND IF WE CAN GET A CALM/CLEAR NIGHT.

AVIATION...MAINLY MVFR CONDITIONS EXPECTED INTO THE EVENING HOURS
WITH IMPROVING CONDITIONS FROM NORTH TO SOUTH AS THE UPR LOW PULLS
AWAY FROM THE RGN. HIGH PRESSURE BUILDING INTO WI ON THU WL ALLOW
FOR VFR CONDITIONS TO PREVAIL.

MARINE...GALE FORCE NE WINDS WL CONT INTO EARLY EVENING AND BE
REPLACED BY A SMALL CRAFT ADVY FOR THE REMAINDER OF THE NGT AS
WAVES SLOWLY SUBSIDE.
