AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
247 AM CST MON JAN 30 2012

.SHORT TERM...TODAY/TONIGHT/TUESDAY. CLEAR SKIES EARLIER TONIGHT
HAVE ALLOWED TEMPERATURES TO PLUMMET...BUT CLOUDS AND START OF THE
WAA HAVE RESULTED WITH TEMPERATURES ON A GRADUAL REBOUND EARLY
THIS MORNING. OTHERWISE RADARS OVER THE REGION SHOW THE WAA BAND
OF SNOW INCREASING OVER EASTERN MINNESOTA AND WESTERN WISCONSIN
AND GRADUALLY WORKING INTO THE AREA THIS MORNING. THIS BAND OF
PCPN IS THE PRIMARY WEATHER EVENT FOR THIS FORECAST PERIOD.

DUE TO THE INITIALLY DRY AIR MASS...SNOW OVERALL STARTING OUT SLOW
ON THE ADVANCING BAROCLINIC ZONE DUE TO THE SATURATION PROBLEM.
BEST UPPER JET DYNAMICS CONFINED THIS MORNING SO OVERALL FORECAST
APPEARS GOOD WITH A PERIOD OF LIGHT SNOW THIS MORNING BEFORE
SUBSIDING TO A NON MEASUREABLE MIX PCPN FROM SOUTH TO NORTH AS THE
DAY WEARS ON. SNOW AMOUNTS WILL LIKELY BE AROUND AN INCH WITH SOME
LOCALLY HIGHER AMOUNTS NORTH OF GREEN BAY.

FOR TONIGHT THE H8 WARM FRONT LIFTS NORTH OF THE STATE BUT A WEAK
SURFACE FRONT STALLS OVER CENTRAL WISCONSIN. MODELS DIVERT ON THE
DEVELOPMENT OF A LOWER STRATUS DECK BUT SOME POTENTIAL OF LIGHT
FREEZING DRIZZLE ALONG AND NORTH OF THIS SURFACE WARM FRONT. FOR
NOW WILL CONFINE A SMALL MENTION OF FREEZING DRIZZLE OVER THE
NORTH TONIGHT INTO TUESDAY MORNING WHERE THE AIR MASS COULD BE
MORE SATURATED AT THE SURFACE.

WILL KEEP SMALL POP MENTION NORTH ON TUESDAY AS THE FRONTAL SYSTEM
TRACKS OVER. WILL ALSO KEEP A BRIEF VERY LIGHT RAIN OR SPRINKLE
MENTION FOR EAST CENTRAL WISCONSIN AS THE COOL FRONT SLIDES OVER.

.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY. EXCEPT FOR A FEW FLURRIES
ACROSS THE FAR NORTH TUESDAY NIGHT...LITTLE IN THE WAY OF WEATHER
TO DEAL WITH UNTIL EARLY NEXT WEEK. THE ONLY CONCERNS THAT WILL
NEED TO BE ADDRESSED WITH LATER SHIFTS IS THE POTENTIAL FOR LATE
NIGHT/EARLY MORNING FOG DUE TO MELTING SNOW...LIGHT WINDS AND SOME
POTENTIAL FOR CLEARING SKIES AT TIMES ON SOME OF THE NIGHTS LATER
IN THE WEEK. ABOVE NORMAL TEMPERATURES WILL CONTINUE THROUGH THE
WEEKEND...ALTHOUGH NIGHT TIMES LOWS COULD BE TRICKY AT TIMES DUE
TO SNOW COVER AND THE POTENTIAL SOME DECREASE IN CLOUDS AND LIGHT
WINDS. MIN TEMPERATURES COULD BE SEVERAL DEGREES LOWER THAN WHAT
IS IN THE CURRENT FORECAST...ESPECIALLY AT THE TYPICAL COLDER
LOCATIONS ACROSS NORTH CENTRAL WISCONSIN.
&&

.AVIATION...CIGS AND VSBYS WILL FALL QUICKLY BETWEEN 09Z AND 12Z
TODAY AS AN AREA OF SNOW FORMS NORTH OF A WARM FRONT. THE SNOW
WILL TAPER OFF BY EARLY AFTERNOON. THERE IS A SMALL CHANCE OF
FREEZING DRIZZLE MONDAY AFTERNOON BUT DID NOT INCLUDE IN TAFS
RIGHT NOW AS CHANCE IS SMALL. MOST AIRPORTS SHOULD SEE 1 TO 2
INCHES AT MOST BY NOON.
