Update
The lake effect snow band is taking shape just off shore over lake
michigan. The latest radar observations and short term model
guidance indicate that the heaviest portion of this band should
remain just off shore, with only a few light snow showers
affecting extreme eastern portions of milwaukee, racine and
kenosha counties. Any additional snow accumulation should
generally be around an inch or less, and mostly confined to areas
between i-94 and lake michigan.

Given the limited additional snowfall and winter weather impacts,
have gone ahead and cancelled the winter storm warning a few hours
early.

Marine
Gusty north winds will persist overnight across lake michigan,
with gales ongoing over the far southern portion of the open
waters. In addition, very cold temperatures will combine with the
gusty winds to produce a risk for heavy freezing spray, especially
where wave action is a bit higher. A heavy freezing spray warning
is in effect until mid day Sunday for all of the open waters and
lake michigan, as well as the nearshore waters off of the
shoreline of southeastern wisconsin.

Freezing spray (and occasionally heavy freezing spray) will remain
a concern for the next few days, as very cold temperatures region
over the region.

The next system of interest will approach the area Tuesday, with
increasing southeast winds ahead of it, especially across the
southern part of the lake. Winds may approach gale force with this
system.

Another shot of very cold air will build into the area mid to late
week, bringing with it a renewed threat for heavy freezing spray.

Aviation(00z tafs)
A band of lake effect snow will continue to move along the lake
michigan shoreline this evening into the overnight hours. This
will bring periods of ifr visibility to mke and enw, along with
MVFR ceilings. Expect to see another 1 to 2 inches of snow at the
airports, with slightly higher amounts right along lake michigan.

Winds will also remain gusty, with north winds gusting in the
25-30 knot range at times. The gustiness should subside late
tonight, though winds will remain breezy.

Further west, waukesha will see flurries for another hour or two,
and then should be done through the rest of the TAF period. Once
the flurries end,VFR will prevail. No additional precipitation
is expected at msn, withVFR expected through tomorrow. Both
sites could see some minor blowing drifting of snow, however, with
the breezy north winds.

Prev discussion... (issued 325 pm cst Sat jan 19 2019)
short term...

tonight and Sunday - confidence... Medium to high.

Moderate lake effect band extending from the northern open waters
of lake michigan toward northern sheboygan county should swing
south across the lake shore counties through the evening. Latest
rap indicates lake band may reintensify over eastern portions of
milwaukee,racine and kenosha counties during the evening as low
level winds re-energize to around 25 knots, increasing the low
level convergence and omega. Will continue winter weather advisory
for sheboygan and ozaukee counties for the rest of the afternoon
as this band swings through, with the winter storm warning for the
southern lakeshore counties through the evening. Lake effect band
looks to shift just east of the lakeshore around midnight. Partial
clearing and somewhat diminishing winds along the fresh snow cover
will allow temperatures to fall into the single digits most areas
as 925h temps dip to -16 to -18c. But will need to watch for
potential low clouds from the northern wi slipping into the area
as low level winds increase more from the north. Also, some mid-
high clouds from increasing isentropic lift in the plains may
spread in later tonight in the western areas.

This isentropic lift will remain mostly to the west and southwest
of southern wi on Sunday, with mainly the mid-high clouds sweeping
across wi. Any -sn from this weak lift should remain to the west
as well.

Long term...

Sunday night through Monday... Forecast confidence is medium to
high:
winds will become northeast to east and then eventually southeast
Sunday night into Monday, allowing some lake effect to push back
inland. Any accumulations should be on the low end since the wind
direction will be changing through most of the event, not allowing
the showers to focus on one particular area.

Temps will likely fall below zero most places away from lake
michigan Sunday night given mostly clear skies and light winds.

Below normal temperatures will continue Monday, with temperatures
struggling 20 at best.

Monday night through Tuesday night... Forecast confidence is medium
to high:
models are in pretty good agreement that low pressure will move by
to the south early next week and bring more accumulating snowfall
to southern wisconsin. Warm advection ahead of the system should
result in light accumulations brushing the northern forecast area
Monday night. The meat of the system is then expected to come
through during the day Tuesday, particularly during the afternoon
and evening. Though there is high confidence in widespread
precipitation, there are still some variations among forecast
models with the low track and timing. The northern solutions could
result in some rain mixing in for a period in the southeast,
though the overall picture suggests primarily snow across
southern wisconsin. The latest blend of models suggests a 3 to 5
inch event, though there is still plenty of time for the finer
details to change.

Wednesday through Saturday... Forecast confidence is medium:
below normal temperatures are expected for the second half of
next week, especially toward the end of the week. A shortwave or
two will bring snow chances at times. There is no major system on
the horizon during this period. Though models are all showing
occasional snow chances, there isn't great agreement with
timing placement strength of these systems.
