Area Forecast Discussion
National Weather Service Grand Rapids MI
329 PM EST Sun Dec 18 2016

LATEST UPDATE...
Synopsis/Short Term/Long Term/Hydro/Marine

.SYNOPSIS...
Issued at 330 PM EST Sun Dec 18 2016

Tonight into Tuesday will be very cold. Wind chill values below 0
are expected overnight and will be as cold as -15 F Monday morning
further south and east, toward Kalamazoo, Lansing, and Jackson.
Monday will be a cold day, and breezy winds certainly won't help.
Strong winds are expected on Tuesday, which will likely impact
travel for high profile vehicles. Mainly seasonal temperatures are
expected from Wednesday on with no major weather systems.

&&

.SHORT TERM...(This evening through Tuesday night)
Issued at 330 PM EST Sun Dec 18 2016

Main impact weather in the short term is bitter cold wind chills
tonight into early Tuesday. In addition, strong winds on Tuesday
will cause travel issues for high profile vehicles. These winds may
also blow the current snowpack around, especially in open country
and near Lake Michigan.

Light lake-effect snow showers will continue this evening and
overnight, transitioning from the northwest flow snow belt to west
flow zones tonight. Minor accumulations are possible in the
southwest forecast area through this evening. Little to no
accumulation expected overnight.

Light snow showers will continue in west flow mainly near and west
of US-131. The DGZ remains saturated through 7 am Monday, with
diminished lift confined closer to the lakeshore. Similarly, 925-850
mb Omega is forecast to be weak and organized in a narrow band along
the coast.

A very cold night is in store, especially further from the influence
of Lake Michigan. Moisture depth decreases tonight, and the eastern
and southern CWA will see clouds thin and scatter out. The boundary
layer will likely decouple, which should suppress the wind Monday
morning. But temperatures will plummet. The wind chill is expected
to drop to around -5 F in Grand Rapids at 7 AM Monday, with -10 to -
15 F readings further south and east in Lansing, Kalamazoo, and
Jackson areas. Monday will be a cold day with highs between 10-15
degrees for many areas. Areas north of a line from Holland to Mt.
Pleasant will stay relatively warmer thanks to southwest winds and
more of a lake influence with highs in the low 20s.

Strong winds are expected to develop Monday night and Tuesday. A
strong low level jet pushes across Michigan on Tuesday in advance of
a low pressure system moving across southern Ontario. The strongest
winds are expected early Tuesday morning into Tuesday afternoon, and
a Wind Advisory could even be warranted near the lakeshore. Wind
gusts to 35-40 mph will be possible inland, with gusts of 40-50 mph
near the immediate lakeshore.

.LONG TERM...(Wednesday through Sunday)
Issued at 330 PM EST Sun Dec 18 2016

The moderation in temperatures that occurs in the short term remains
in place through much of the long term. Today's model runs may even
be slightly warmer than yesterday's in terms of 850mb temperatures.
Much of the time we are between -4C and +4C at 850mb which would
lead to fairly seasonable to even slightly above normal temperatures.
The one time frame that looks cooler is on Thursday behind a mid
week low pressure system where we cool to -9C which is not all that
cold for this time of year and the thermal trough is very transient.
So, in general expecting a lot of highs in the 30s and lows in the
20s.

A fairly weak clipper type of system will move through the area
Wednesday and Wednesday night bringing light snow to the area.
Highest accumulations of possibly an inch or two will be across
Central Lower Michigan near the track of the low center. Any cool
down will be short lived behind the system with limited lake effect
potential as the upper flow is zonal. Any cold air is quickly swept
east.

The operational GFS and ECMWF diverge somewhat at the end of the
long term on Saturday and Sunday. The ECMWF has a more wrapped up
system for Saturday, whereas the GFS has a weaker surface trough. On
Sunday the ECMWF deepens a strong low in the plains lifting it into
the Western Great Lakes. The GFS is weaker and flatter with the
system. Like the GFS more here given its track record lately and the
zonal flow in place ahead of it.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 126 PM EST Sun Dec 18 2016

The dominant lake effect snow band that was over Western Lower
Michigan this morning is weakening and shifting inland at 18z. The
band recently moved through KAZO and the visibility dropped to
1/2SM for a time.

Conditions should be improving this afternoon as the band will be
weakening as it is driven inland away from its source, Lake
Michigan. We are still expecting MVFR ceilings this afternoon off
of Lake Michigan however with periods of VFR as well. The lake
effect snow showers will persist this afternoon and into tonight,
but will be much weaker than what occurred this morning.
Visibilities much of the next 24 hours will vary between VFR most
of the time and MVFR in heavier snow showers. Ceilings will be
much the same.

Winds will shift from northwest this afternoon to southwest
tonight and Monday morning.

&&

.MARINE...
Issued at 330 PM EST Sun Dec 18 2016

Dangerous conditions for small craft will continue on Lake
Michigan through Monday afternoon. A Gale Warning will be issued
for Lake Michigan Monday afternoon through Tuesday evening.
Southwest gales to 35 knots expected to develop late Monday. Large
waves are expected.

&&

.HYDROLOGY...
Issued at 330 PM EST Sun Dec 18 2016

Ice jam potential appears to be lowering at this time since
no significant triggers (ie. increased river flows, abrupt
warming, etc.) will be present this week. Given the erratic behavior
of ice jams, however, river ice will continue to be monitored.

Stable ice development is noted on the Grand River at Robinson
Township and is likely occurring in other areas on larger rivers as
well. This will continue into Tuesday morning before warmer
conditions this week will not be conducive to ice growth, but
neither will the temperatures be warm enough to start breaking up
and moving the ice.

Some gauges like the White River gauge at Whitehall and the Flat
River gauge at Smyrna have shown spikes in observed gauge height
readings due to ice likely impacting the gauge itself, not ice
jamming. These spikes can occur fairly frequently during the winter
and do not necessarily indicate ice jamming is occurring.

Current river ice analysis is showing ice coverage across the
Kalamazoo River at New Richmond. Possible ice development exists on
the Muskegon River at Big Rapids with the sensor still showing 0C.
