Area Forecast Discussion
National Weather Service Green Bay WI
1159 AM CST Thu Jan 5 2017

New Information added to update section

.UPDATE...
Issued at 1158 AM CST Thu Jan 5 2017

Wind chill headlines for today/tonight coded below.

UPDATE
Issued at 953 AM CST Thu Jan 5 2017

Wind chills got a lower than expected overnight, and as a result
have been recovering a little more slowly than anticipated. But
despite the fact that many of the ob sites in the portion of the
advisory set to expire at 10 am will still be AOB -20 at 10 am,
conditions are slowly improving. Will allow that portion of the
advisory to expire as scheduled.

The situation for tonight is still not totally clear. Winds are
expected to be a little lighter than Wednesday night/early this
morning. The west will likely meet criteria again tonight, but
the east is more uncertain. Will make a decision on new headlines
later today.
&&

.SHORT TERM...Today...Tonight...and Friday
Issued at 304 AM CST Thu Jan 5 2017

Very cold temperatures and winds continue to bring dangerous wind
chills to northeast Wisconsin early this morning. While sunrise
will allow temperatures to rise a bit later this morning,
decoupling will allow stronger winds to reach the surface and
cause wind chills to remain at criteria for several more hours.
Therefore will allow the Wind Chill Advisory to continue through
the morning hours before wind chills warm into the teens during
the afternoon.

A patch of clouds across Minnesota and western Wisconsin will
track east during the morning hours, which could bring a few
flurries to the area as they pass through. Otherwise quiet weatheris
expected across the majority of the area as light lake effect snow
showers wind down across Vilas County.

The main weather concern later tonight will once again be wind
chills. Although winds will be lighter than last night, overnight
lows are expected to be several degrees colder, making reaching
wind chill advisory criteria easier. At this time it appears
central and north central Wisconsin will likely need another Wind
Chill Advisory tonight and Friday morning, with east central and
northeast Wisconsin possibly needing a headline as wind chills get
very close to criteria. Given the current headlines in effect for
this morning will hold off on issuing headlines for tonights event
until later shifts.

.LONG TERM...Friday Night Through Wednesday
Issued at 304 AM CST Thu Jan 5 2017

Long range models are in good agreement with the handling of the
mean flow through this weekend into early next week with a deep
upper vortex over the eastern Pacific, a modest upper ridge over
the western CONUS and a deep longwave trough over the eastern
CONUS. There are subtle differences with the speed of a piece of
energy ejecting eastward across the CONUS from the Pacific vortex
toward the middle of next week. This system would be our first
chance of seeing widespread precipitation, with precipitation type
issues possible. Until then, arctic air will dominate our weather
through Sunday with temperatures 10 to 20 degrees below normal,
before a warm-up begins on Monday.

A weak cold front is still expected to move through WI Friday
night and help to reinforce the arctic air over the region. Air
mass appears too dry to sustain any precipitation, however a
subtle wind shift to the west-northwest may be enough to bring
lake effect snow showers or flurries into Vilas county toward
daybreak. Another frigid night on tap with min temperatures around
10 below zero north-central WI, to near zero along Lake MI. Models
send a shortwave trough into the Great Lakes on Saturday and with
a cyclonic flow in place, anticipated additional lake effect snow
chances mainly across Vilas county. Trajectories are not set up
the best (west-northwest versus preferred north-northwest), thus
do not expect to see much in the way of accumulation (under an
inch). The rest of the forecast area will see a mix of sun and
clouds with max temperatures ranging from zero to 5 above north-
central, to around 10 above over eastern WI.

The chances for lake effect snow showers will continue into
Saturday evening, mainly again over Vilas county with little in
the way of accumulation. This will be due to the approach of a
large area of Canadian high pressure over the Midwest that is
expected to back the winds to the west and keep additional lake
effect snows north of the MI border. Yet another very cold night
to deal with Saturday night as mostly clear skies allow
temperatures to easily fall below zero away from Lake MI. Look for
min temperatures to range from 10 below to 15 below zero north-
central, to around zero near the lake. Once again, there should be
enough wind to send wind chill values into the -15 to -30 degree
range and likely prompt another wind chill advisory for parts of
northeast WI. The northern extension of this large high pressure
is forecast to move across WI Sunday morning and reside to our
east by Sunday afternoon. Winds will slowly back through the day,
going from west-northwest to south-southwest by 00z Monday. The
core of arctic air will get shoved to the east and the start of a
warm-up is expected, but not really be noticed until Monday.
Northeast WI should see one more cold day with max temperatures of
5 to 10 above central WI, 10 to 15 above eastern WI. Winds will be
relatively light with the surface high nearby, therefore wind
chills are forecast to be a few degrees either side of zero by
Sunday afternoon.

A relatively weak system is forecast by the models to impact our
weather later Sunday night into Monday. This system, consisting of
a very weak low pressure, a cold front and modest mid-level trough
energy may have enough moisture available to bring a chance of
light snow to all of northeast WI. Right now, it appears any
accumulations would be on the light side. Other than the snow
chance, the bigger story would be the return of temperatures to
normal levels for early January. Look for readings to reach around
20 degrees north, middle 20s south.

The better likelihood of seeing a more widespread precipitation
event arrives later Monday night into Tuesday as an area of low
pressure moves northeast from the central/southern Plains into the
Great Lakes. Models are still waffling on the exact track that the
surface low would take ranging from northern IL into Lower MI, or
from northwest IA into central WI. A western track would bring
precipitation type issues into play over eastern WI. Obviously,
this track could easily shift several times in the coming days,
thus a system to closely watch. Another issue with this system
will be the strength of the surface low which varies greatly among
the models. A strong low pressure would impact wind speeds and
potential for more blowing/drifting of any snow. Max temperatures
for Tuesday to range from the upper 20s north-central, to the
middle 30s east-central WI.

Snow chances would carry over into Tuesday night before ending as
the surface low pulls away into southeast Canada. Wednesday looks
to be dry and a bit cooler with high pressure moving across the
region. Max temperatures to be closer to normal with readings
around 20 degrees north-central, middle 20s east-central WI.

.AVIATION...for 18Z TAF Issuance
Issued at 1119 AM CST Thu Jan 5 2017

Generally good flight conditions expected during the period.
Surface winds will slowly decrease. Patches of clouds will drift
through the region at times. Although brief MVFR ceilings are
possible, uncertainties in the timing/location/duration of those
preclude being able to specify them in the TAFs. The one TAF site
where a period of MVFR cigs seems more likely is RHI this
afternoon, as patchy clouds off Lake Superior drift south before
dissipating.
