DISCUSSION...
High pressure centered over South Dakota with a ridge axis that
extends east across the Great Lakes will provide dry cool weather
along with mainly clear skies through Wednesday night. Exception
will be band of some mid and high level clouds this afternoon and
evening. This is being produced by long narrow ribbon of strong pva
from the Midwest through the Great Lakes and will drop south of the
area by midnight. Clear skies and light winds tonight will allow for
good radiational cooling down to dew points in the mid to upper 20s.
Should see a good deal of frost in the morning.

Plenty of sunshine Wednesday with winds backing to the west
southwest as surface high pressure slowly sinks south. Highs will be
slightly below average in the low to mid 40s.  Clear skies will
continue  the first half of Wednesday night before clouds begin
increasing from the northwest ahead of the seasons first arctic
airmass that will sweep into the area Thursday afternoon. Increasing
warm air advection ahead of the cold front will keep lows Wednesday
night a bit warmer mainly in the low 30s.

The arctic front will reach the Saginaw Valley late Thursday morning
and exit the state by evening. Moisture will be lacking with best
moisture and dynamics remaining across northern Lower. Will still
have a scattering of rain showers just ahead of the front and
possibly mixing with snow after passage. Sky will clear for Thursday
night with exception along Lake Huron shoreline in the Thumb where
lake effect clouds and light snow is possible. Lows Friday morning
mainly teens with wind chills possibly in the single digits in some
locations.

Cold air will continue to funnel into the area on Friday as high
pressure drops in from the north and over the Great Lakes region.
Temperatures at 850mb by Friday morning look to be in the -15C to -
18C range.  Highs Friday will be the coldest temps in the extended
as highs struggle just below freezing.  The high pressure situated
over the area will move eastward by later in the day on Saturday,
which will give way to the next wave.  This wave is currently
advertised to move across the Ohio Valley, bringing a chance for
snow showers and possibly a mix of snow/rain Saturday evening
through Sunday.  The start of next week switches around to dry
conditions again as more expansive high pressure builds in from the
Plains.

MARINE...

A ridge of high pressure nosing into the Great Lakes will maintain
relatively tranquil marine conditions across much of the area
tonight. West southwesterly flow will then increase on Wednesday as
this ridge settles south and a cold front approaches from the north.
Expect wind gusts into the 25 knot range at times over parts of Lake
Huron.

This flow will increase late Wednesday night into early Thursday as
this strong cold front reaches the northern portions of Lake Huron.
The front will then surge south through the rest of the Great Lakes
region on Thursday, bringing a good likelihood of northwest gales
over much of Lake Huron with 40 knot gusts possible over the open
waters. A Gale Watch will continue in anticipation of these
conditions, which will linger into Thursday night.
