Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
239 PM CST Wed Jan 4 2017

.TONIGHT AND THURSDAY...Forecast Confidence Is High.

The pressure gradient will remain tight tonight into Thursday
morning, before slowly relaxing during the afternoon hours. This
will still bring gusty west northwest winds during this period.
Lows tonight will drop into the 5 below to 5 above zero range,
coldest northwest of Madison. Highs Thursday should be in the 5 to
10 above zero range.

Wind chills will drop into the 10 below to around 20 below zero
range tonight into Thursday morning, coldest across northern
portions of the area. However, not expecting wind chills to dip
below 20 below zero long enough to issue a Wind Chill Advisory at
this time.

.FRIDAY - Confidence...High
A continued cold period expected. Weak vort lobe passes across with
surface ridging nosing in from the southwest. Expect a somewhat more
slack pressure gradient but enough to keep a west wind going for
much of the day. 925 temps -18c to -22c so still bitterly cold.

.FRIDAY NIGHT THROUGH SATURDAY NIGHT - Confidence...Medium to High
A little modification due to brief waa ahead of the next reinforcing
cold front. Oner weaker shortwave passes to our north friday night
and then another stronger one passes north again Saturday. An
associated low and cold front will slide through Saturday. 925 winds
turn northwest and bring another 925 -20c thermal trough into the
area. So likely to see some more negative double digit wind chills
Saturday night.

.MONDAY THROUGH WEDNESDAY - Confidence...Medium
A more unsettled period is expected though a considerable
modification in temperatures is expected for Monday and Tuesday
before next cold front is proggd to arrive Tuesday night. 850 waa
will likely lead to some light snow development on Monday then
stronger push of waa sets up Monday night into Tuesday pushing the
thermal profile into a potential mixy scenario with even some pure
rain possible as 850 through surface temps modify enough to support
the liquid phase in parts of the area. At this time there is decent
agreement for a cold front to push through in the Tuesday night
timeframe. This should shut down the precip and potentially change
any lingering rain or mix to light snow before ending. While some
differences in synoptic pattern on Wednesday the models are showing
a dry scenario.

&&

.AVIATION/00Z TAFS/...Gusty west northwest winds will linger tonight
and Thursday across the area, as Arctic air continues to move into
the region. Gusts up to 30 knots are possible near Lake Michigan
at times.

An area of middle to high clouds will gradually move into the area
from the southwest later this evening into Thursday morning. Not
confident that ceilings will lower Thursday afternoon at this time,
with dry air in the low levels lingering.

&&

.MARINE...A Small Craft Advisory continues through tonight, as west
northwest winds will remain in the 15 to 25 knot range, with gusts
up to 30 knots at times. This is a result of the tight pressure
gradient lingering over the area. Waves of 3 to 4 feet are
anticipated, highest toward the open waters.

Winds may continue to reach Small Craft Advisory levels into Thursday
morning, until the pressure gradient weakens further. Winds and waves
may reach Small Craft Advisory levels Saturday into Saturday
night, and again at times Monday into Tuesday.
