Issued at 326 PM EST Wed Jan 4 2017

Lake effect snow showers will continue tonight, and likely right on
through the weekend. Winds will weaken a little tonight, shifting
the better snow showers back toward the lake a little. Accumulations
are not expected to be heavy, but will gradually add up over time
for western areas. Areas generally along and west of U.S.-131 will
see the highest amounts. Cold air will remain in place through the
weekend with highs mainly 15 to 20, and lows 5 to 15 degrees.

.UPDATE...
Issued at 952 PM EST Wed Jan 4 2017

No change in the headlines planned with this update. The item of
note however is the moisture streaming east out of Iowa and
Southern Minnesota. This moisture is associated with an upper
shortwave trough that is moving our direction from the Dakotas.
The moisture mainly affects the southern half of the forecast
area, but the shortwave drives right through the entire area
Thursday morning. Expecting an uptick in lake effect snow coverage
and intensity late tonight and Thursday morning. Looking at
probably a 6 to 9 hour period of enhanced, more widespread snow
showers.

Bottom line, the Winter Weather Advisory continues as is, with
travel impacts going forward especially given the cold
temperatures and persistent snow. The expected increase in coverage
and intensity late tonight and tomorrow morning only strengthens
the cause for the headline.

.SHORT TERM...(This evening through Friday night)
Issued at 326 PM EST Wed Jan 4 2017

We will be extending all of the counties in the advisory, except
Osceola county, out through Friday afternoon. We will keep the
original expiration time of 10 am Thu for Osceola county as we
expect the impacts will lessen enough there by then.

The lake effect pattern is in place now with the arrival of the cold
air, and will not change significantly through the short term. H850
temps of around -20C are producing moderate to extreme instability
over the lake. Accumulations have been limited as expected with
inversion heights a bit limited, strong cloud layer winds spreading
the bands out, and a shallow DGZ low in the clouds and below cloud
bases.

We expect that snow may accumulate a little better starting tonight
with winds coming down a little and breaking up the bands less. The
other aforementioned factors remain in play tonight, so accums
should not get out of hand. The mean cloud layer flow will remain
generally 280-300 which will favor the SW quarter of the CWFA.
Accums might become a little better on Thu and Thu night as a short
wave approaches. This will bring the area forcing and mid/upper
level moisture, and inversion heights will come up some.

Conditions will gradually become a little less favorable on Fri as
the system and mid/level moisture moves east of the area and
inversion heights drop again. Snow showers will remain however with
more light accumulations expected. Winds will shift a bit on Fri
night ahead of an incoming

.LONG TERM...(Saturday through Wednesday)
Issued at 326 PM EST Wed Jan 4 2017

The long term period starts off with another vort max digging down
the backside of the mid level trough over the Great Lakes Region.
This feature sharpens the trough axis up Saturday into Saturday
night over MI.  With the airmass still plenty cold enough for lake
effect...there should be a continuation of the snow showers.  The
flow becomes northerly behind this feature.  That will raise the
risk for a stronger band of snow to set up along the shoreline.  If
this happens...heavier snow could occur.  The main period for this
to possibly occur would be Saturday night into Sunday.

Warm air and moist advection is shown to develop Sunday night which
then continues through Tuesday.  Thus the risk for precipitation
will increase.  Initially snow will result...but as the temperatures
warm up...some rain will be possible.  A cold front pushes through
by Wednesday.  This will support more in the way of snow for the
region.  It looks like this will be a shallow cold airmass moving in
on Wednesday as the 925 mb temps are shown to be colder than the 850
mb temps.

.AVIATION...(For the 00Z TAFS through 00Z Thursday evening)
Issued at 724 PM EST Wed Jan 4 2017

Lake effect snow will continue to pour off of Lake Michigan the
next 24 hours. MVFR conditions will be the dominant mode with
ceilings between 2000-3000ft being common. Visibilities towards
Lake Michigan (AZO, GRR, MKG) will also be in the MVFR category,
occasionally dipping into the IFR category as well.

There may be a flare up in the coverage and intensity of snow late
tonight into Thursday morning between 09z and 18z. Winds will
gradually tone down some as we move through tonight. Late tonight
and on Thursday winds should be more on the order of 10 to 20
knots.

.MARINE...
Issued at 326 PM EST Wed Jan 4 2017

We will make a last minute decision on whether to keep the Gale
Warning, or to transition the headlines to a Small Craft Advisory.
The core of the winds aloft have moved by the nearshore waters, and
winds have come down slightly. They will come down a little more,
but remain up high enough and long enough (through Thu) to require
an advisory. Freezing spray will become less of an issue as winds
and waves come down.

.HYDROLOGY...
Issued at 1221 pM EST Wed Jan 4 2017

We have seen considerable improvement in river levels for sites
affected by advisories. Two of the four have been cancelled and a
third (Ionia) could be dropped in the near future. That would
leave us with just one advisory at Maple Rapids. Other sites are
showing signs of stabilizing and this trend should continue with
the cold temperatures and freezing of potential ground runoff.

Temperatures today through Friday will remain well below 20
degrees with sub-20s possibly extending into much of Saturday. Ice
formation is likely on rivers and will require monitoring through
the weekend. Liquid precipitation equivalent through Saturday
will remain fairly light inland (likely less than 0.25") with
anything higher along and west of U.S. 131 and confined to heavier
snow bands. Much of this will remain locked up in the snowpack
until conditions warm up again.
