Area Forecast Discussion
National Weather Service Green Bay WI
228 PM CST Mon Dec 19 2016

Forecast discussion for routine afternoon forecast issuance

.SHORT TERM...Tonight and Tuesday
Issued at 228 PM CST Mon Dec 19 2016

There are a couple of items that will need to be dealt with over
the next 24 hours. First, there are temperatures which may drop
off a bit this evening, but then start to rise overnight as strong
WAA prevails over the region. Second, there is snow chance headed
into Tuesday as a weak system passes to our north.

The 20z MSAS surface analysis indicated a large area of high
pressure that extended from TX northeast through the Ohio Valley
into the northeast CONUS. A strong area of low pressure was
situated over northern Alberta. A tight pressure gradient was in
place from the Plains into the Great Lakes with the resultant
southwest winds helping to "warm" temperatures up.

The WAA, coupled with these brisk southwest winds at 10 to 20 mph,
will persist across northeast WI tonight. Expect to see patches of
mid/high clouds pass overhead through the night, but it is the
strength of the WAA that will impact temperatures the most.
Anticipate min temperatures to occur early this evening with
readings slowly rising through the night, reaching the 15-20
degree range by daybreak. Wind chills should only dip into the
single digits below zero through most of the night, thus no need
for headlines.

Attention turns to a relatively weak, fast-moving system moving
across southern Ontario/northern sections of the Great Lakes on
Tuesday. This system, compromised of the aforementioned area of
low pressure, a cold front and a mid-level trough, is forecast to
brush northern sections of WI mainly during the late morning/early
afternoon hours. Previous shift already had a small pop mainly
north of Highway 8 with flurries farther south. Central and east-
central WI appear to miss the snow altogether with low clouds as
far south as Highway 29. Anyway you slice it, this system will not
cause any problems for people out and about on Tuesday. Probably
the worst thing will be the gusty southwest winds that will veer
west behind the cold front. Wind gusts could surpass 30 mph at
times. Max temperatures for Tuesday will range from the upper 20s
to lower 30s throughout the entire forecast area.

.LONG TERM...Tuesday Night Through Monday
Issued at 228 PM CST Mon Dec 19 2016

Medium range models suggest that winter will take a
break from Wisconsin for the remainder of this week as the upper
flow becomes nearly zonal through Friday. They also forecast the
possible approach of a significant synoptic scale system Christmas
Day.

Dry and milder than usual weather expected Tuesday night with
clouds and warm advection as a clipper like system approaches from
the northern Plains. It is currently over the Gulf of Alaska, so
the track and time of arrival is likely to change. For now, the
models are fairly consistent in keeping the greatest snow north
of the Michigan border Wednesday and Wednesday evening with only
an inch or two across our forecast area.

Quiet and mild weather expected Thursday through Saturday with
temperatures 10 or more degrees above normal. The models are
currently in agreement about bringing a significant upper system
from the Four Corners region toward Minnesota Christmas Day through
Monday, with a surface low tracking well to our west. If this does
materialize it would bring some light snow Christmas day that
would change to a moderate rain over most of the forecast area
Christmas night before ending as snow showers Monday. The jet
energy for this system is now over the Sea of Japan, so it is
quite possible that the model forecasts will jump around with this
system over the next several days.

.AVIATION...for 18Z TAF Issuance
Issued at 1128 AM CST Mon Dec 19 2016

The main aviation issue from this afternoon into Tuesday night
will be strong winds just above the surface creating LLWS
conditions. Even surface winds could gust over 30 knots at times
on Tuesday as a tight pressure gradient remains in place between
high pressure to our southeast and low pressure move east across
southern Canada.

Expect to see patches of mid and high clouds to continue moving
over northeast WI this afternoon as warmer air replaces the arctic
air. These clouds may briefly depart this evening, but return late
tonight or early Tuesday ahead of a cold front/associated mid-
level trough. The bigger story will be the southwest winds of 40
to 50 knots in the 1K to 2K foot range above ground level tonight.
Have included LLWS wording for all TAF sites.

While VFR conditions should prevail across the vast majority of
northeast WI, northern sections of the state may see cigs briefly
go into the MVFR category on Tuesday with some passing flurries as
the cold front sweeps through.

CURRENT TRACK WOULD BRING RAIN, SNOW AND MILDER TEMPERATURES TO
WISCONSIN. THE FORECAST TRACK OF THE STORM AND RESULTING WEATHER
COULD EASILY CHANGE OVER THE NEXT FEW DAYS, SO BE SURE TO MONITOR
