Discussion
Rest of this morning through tonight... Forecast confidence is
medium...

light precipitation continues across the region early this
morning, mostly in the form of drizzle or freezing drizzle, though
a few snowflakes have been mixing in on occasion. Temperatures
south of i-94 are generally above freezing, with readings at or a
degree or so below freezing north. Thus far, impacts from any
freezing precipitation have been little to none, with pavement
temps seemingly a couple of degrees warmer than ambient air
temps, and thus just above freezing. We'll continue to closely
watch any travel impacts as we head toward the Monday morning rush
hour.

Most precip should be done by daybreak, with clouds sticking
around through most of the morning. Clearing should begin to take
place by afternoon, though the exact timing of that clearing
remains in question.

Temperatures today should range from the upper 30s north to low to
mid 40s south, where sunshine should be more widespread.

Temperatures tonight are expected to fall back into the low to mid
30s area-wide.

Tuesday through Wednesday night - confidence... Medium
strong northwest mid level flow becomes broadly anticyclonic this
period with low level surface ridging being dominant. There is a
hint of a return flow setting up later Wednesday with some of this
possibly reaching our far north or northwest. The gem and ecmwf
keep this out of our area while the GFS brings it in. Will ride
with the superblend pops for now which keep our area dry. A little
surprised the superblend isn't giving us at least some small pops
Wednesday night as that isentropically induced band skims our
northern cwa. Will leave dry forecast for now.

Thursday through Friday night - confidence... Medium
main focus of the forecast centers on a potent storm system
lifting northeast from the central southern plains. The progs
continue to show surface 850 tracks and baroclinic zone placement
that favors the better snow potential across the northern and
northwest cwa. The consensus of the GFS and ECMWF surface tracks
brings it either into extreme southeast wi or extreme northeast
il. The 850 low tracks are across central wi with the ECMWF quite
broad with this feature. The cold air doesn't really get pulled
into the southeast until later Friday or Friday night. The ecmwf
is slower in this regard. So still potential for a potpourri
across our forecast area with the southeast looking more rain than
snow at this time and the north seeing a longer window within a
more thermally favorable environment for snow production. So at
this time the thinking is our northern CWA will be more under the
gun for the most impactful conditions. Both the GFS and ECMWF pull
some fairly warm 850 temps into the southeast CWA Thursday night
and Friday morning so have adjusted the blended numbers a bit
warmer to account for this consensus.

Saturday and Sunday - confidence... Medium
colder air arrives with still some timing differences on how
quick the bitter air arrives. The GFS is overall quicker and
colder bringing 925 temps of GOES down to the minus teens celsius
for Saturday and into the -20s celsius for Sunday along with a
gusty wnw wind regime. Meanwhile the ECMWF develops some light
snow Saturday night into Sunday along the slower arriving arctic
front. Will stick with the superblend numbers this far out. Bottom
line looking like a bitterly cold christmas eve and some
locations may need some temp reduction due to the potentially
fresh snow cover in place.

Aviation(09z tafs) Mix of light rain and drizzle continues to
affect the terminals this morning. At sites appear to be at or
just above freezing, limiting impacts from any freezing
precipitation.

In general, ifr conditions will continue through mid morning,
before ceilings begin to lift and gradually scatter out.

Winds will pick up from the southwest today as well, with a few
gusts possible by afternoon.

Marine Winds will increase from the southwest today and
tonight, and a small craft advisory will go into effect this
evening through tomorrow evening, with gusts between 25 and 30
kts.

Winds will decrease for a time Wednesday, before the next storm
system begins to impact the region Thursday and Friday.

Mkx watches warnings advisories
Wi... None.

Lm... Small craft advisory from 6 pm this evening to 6 pm cst Tuesday
for lmz643>646.

Today tonight and aviation marine... Boxell
Tuesday through Sunday... Collar
