...ARCTIC FRONT TO BRING GALES TO LAKE HURON WEDNESDAY AND
THURSDAY...

.THE FIRST OF TWO COLD FRONTS IS PASSING EAST THROUGH INTO LAKE ERIE
AT PRESS TIME. COLD AIR ADVECTING AND A TIGHTENING PRESSURE GRADIENT
BEHIND THE FRONT WILL KEEP WINDS ELEVATED TO SMALL CRAFT CRITERIA
THE REST OF TODAY THROUGH TONIGHT. THE PASSAGE OF A SECONDARY COLD
FRONT INTO THE NORTHERN GREAT LAKES ON WEDNESDAY WILL MARK THE
ARRIVAL OF MUCH COLDER AIR. IN ADDITION, THE GRADIENT WILL TIGHTEN
FURTHER AS THE TROUGH RUNS INTO STRENGTHENING HIGH PRESSURE BUILDING
INTO THE OHIO VALLEY. THIS GRADIENT AND DEEPER MIXING BEHIND THE
FRONT LOOKS TO SUPPORT WIDESPREAD GALES ACROSS LAKE HURON. GALES
SHOULD BEGIN WEDNESDAY MORNING, AND WITH LITTLE CHANGE IN THE
OVERALL PATTERN WILL PERSIST THROUGH THURSDAY. PERIODIC HIGH END
GALES WILL BE POSSIBLE AS WELL THROUGH THE EVENT.  THE STRONG WINDS
COMBINED WITH THE ARCTIC AIR WILL ALSO CAUSE SOME FREEZING SPRAY.

409 AM EST THU DEC 15 2016

...STRONG WEST WINDS AND FREEZING SPRAY TODAY...

.A SURFACE TROUGH AXIS IS NOW PUSHING INTO FAR NORTHERN LAKE HURON.
THIS TROUGH AXIS COMBINED WITH STRONG HIGH PRESSURE EXPANDING ACROSS
THE UPPER MIDWEST WILL ENHANCE THE NORTHWESTERLY GRADIENT ACROSS THE
THE REGION, ESPECIALLY CENTRAL AND SOUTHERN LAKE HURON. THIS WILL
SUSTAIN THE GALE FORCE WIND GUSTS ACROSS LAKE HURON THROUGH THE DAY.
ENHANCED FLOW JUST SOUTH OF THIS TROUGH AXIS MAY ALSO SUPPORT SOME
HIGHER END GALE FORCE GUSTS (UP TO 45 KNOTS) OVER SECTIONS OF
CENTRAL LAKE HURON. THE WIND GUSTS WILL BE SLIGHTLY LOWER ACROSS
LAKE ST CLAIR AND WESTERN LAKE ERIE TODAY IN COMPARISON TO
YESTERDAY. THE SUSTAIN WEST-NORTHWEST WINDS WILL STILL SUPPORT LOW
WATER CONDITIONS ACROSS THE WESTERN BASIN OF LAKE ERIE. THE COLDEST
AIR OF THIS ARCTIC OUTBREAK IS NOW OVERSPREADING THE REGION. THUS,
HEAVY FREEZING SPRAY WILL PERSIST OVER MOST OF LAKE HURON. 

THE GRADIENT WILL WEAKEN ACROSS THE LAKES TONIGHT AS THE ARCTIC HIGH
PRESSURE SETTLES INTO THE OHIO VALLEY AND THERMAL TROUGHING BECOMES
BETTER ESTABLISHED ACROSS THE LAKES. LOW PRESSURE IS FORECAST TO LIFT
ACROSS THE EASTERN GREAT LAKES ON SATURDAY. THIS WILL BE A
RELATIVELY WEAK LOW, THUS THE WINDS WILL REMAIN IN CHECK. THERE WILL
BE ANOTHER SURGE OF ARCTIC AIR FOLLOWING THIS SYSTEM ON SUNDAY.
CURRENT MODEL FORECAST SOUNDINGS SUGGEST ONLY A BRIEF PERIOD OF LOW
END GALE FORCE WINDS ARE POSSIBLE ACROSS LAKE HURON ATTM AS THERE IS
EXPECTED TO BE A MORE RAPID WEAKENING OF THE GRADIENT WITH THIS NEXT
PUNCH OF ARCTIC AIR.

Area Forecast Discussion
National Weather Service Detroit/Pontiac MI
601 AM EST Tue Dec 13 2016

.AVIATION...

A expanding region of light snow has developed across sw Lower Mi
along/ahead of a cold front. Although the rapid development to the
west has been a result of lake enhancement, there will be a brief
window of opportunity for light snow from FNT south this morning
ahead of this cold front. Any accums from the snow should be less
than a half inch. The passage of the front, early this afternoon,
will be marked by a wind shift toward the west. Ceilings associated
with remnant strato cu will lift during the afternoon as post
frontal cold air advection raises inversion heights. Dry air
advection may also scatter the clouds out.

.DTW...The southerly flow overnight lifted the MVFR stratus well
north of metro. This has however led to some pockets of fog and LIFR
ceilings due to radiational cooling under a moist boundary layer. The
approach of the front will result in the the development of light
snow, most likely to affect the airport between 14Z and 17Z. The
weak nature of the forcing and brevity of snow suggests minimal
accumulations (under an inch). More widespread stratus will funnel
back across the area this afternoon with the passage of the cold
front, marked by a more westerly wind direction around 20Z.

//DTW Threshold Probabilities...

* Moderate in ceilings below 5000 feet today and tonight.

* High for snow as precipitation type.

.PREV DISCUSSION...
Issued at 302 AM EST Tue Dec 13 2016

DISCUSSION...

Large upper low centered over Manitoba will slowly sink south of St
James Bay by late Wednesday, encompassing the Great Lakes through
the mid-week period. Main effect from this system will be an early-
winter arrival of bitter cold temperatures and wind chills, breezy
conditions, and occasional chances for light snow through the mid-
week period.

Southerly flow this morning has allowed for clearing south of I-94,
and in turn, allowed temperatures to rapidly fall over the fresh
snowpack into the low teens and prompted the development of patchy
freezing fog. This trend should spread north to about the M-59
corridor over the next few hours before clouds arrive from the west
ahead of the next upper wave and cold front. Temps should level off
or slowly rise again as clouds work in, and visibilities that have
lowered in light fog should begin to improve.

Initial surface trough and cold front in advance of the upper low
over Canada will push across the area this morning, during the
roughly 12-18Z period. Upper wave currently exiting Wyoming will
also slide through the Ohio Valley on the south side of the low this
afternoon, aiding lift and low-level moisture transport (850mb
dewpoint plume) into Southeast Michigan ahead of the front. This
will provide a good chance for light snow from about 7AM through
Noon, mainly south of the I-69 corridor. Accumulations look to reach
up to about 1/2 inch, with snow impacting at least some of the
morning commute across Southeast Michigan. Will keep pops in the
lower end of the likely category for now given dry air current in
place over the region and upstream ceilings over the Chicago area.
Otherwise, intrusion of cold air south of M-59 early this morning
will have an impact on max temperatures later today as clouds limit
insolation. Lack of real warm advection ahead of the front and early
day passage should limit max temps to the 20s across the entire
forecast area. Breezy west winds behind the frontal passage should
hold wind chills into the teens this afternoon, with many locations
falling to single digit wind chills by early evening. There should
be some clearing behind the cold frontal passage late in the
afternoon and early evening, before stratus fills back in under a
subsidence inversion formed as high pressure over the plains briefly
expands into the area and flow remains west off Lake Michigan.
Clearing during the evening will allow temperatures to initially
plummet before incoming clouds allow temperatures to level off late.
Mins are forecast to run in the single digits above zero to the low
teens in Detroit (sub-zero wind chills everywhere). Coldest readings
will be along/north of I-69 where clearing will linger the longest
until the ridge expands northward overnight and low clouds fill in.

Second arctic front will push across the area Wednesday
afternoon/evening as another surface trough swings across Ontario.
This will again provide a chance for snow showers, with some lake-
enhancement added in. Low-level moisture coming off the lake may
have only a limited period of residence in the dendritic growth zone
before air becomes too cold with H850 temps diving to -20 to -25C.
This may limit coverage and duration of snow showers. Timing
differences with the frontal passage in the models precludes too
much detail in the forecast at this point with regard to timing.
Deepening boundary layer behind the front will tap into stronger
core of winds aloft that will slide along the south side of the
large upper low to our north Wednesday afternoon and into the early
overnight hours, providing windy conditions with gusts in the 35 to
40 mph range. Max temps in the teens will be reached before frontal
passage, then fall. Wind chills will be in the low single-digits
ahead of the front, before falling back below zero, dipping as low
as -10 to -15F overnight.

Lake-effect will drive any precipitation that falls over Lower
Michigan on Thursday, as the upper low pulls away and heights start
to recover. West-northwest flow will favor locations along and south
of I-94. Thursday is still on track to be the coldest day with max
temps reaching from near 10 to the low teens, and overnight lows
barely above zero. Breezy conditions will maintain sub-zero wind
chills during the day, with weakening wind field overnight perhaps
keeping us from reaching wind chill advisory criteria of -15F.

Large upper trough swinging down through central Canada is forecast
to interact with or phase with energy off the Pacific Northwest
coast late this week. Resultant trough, or shortwave lifting ahead
of the main trough, will send low pressure across the region on
Saturday. There are still many uncertain aspects with this storm
system, leading to questions with precip type by Saturday as the
center of the surface low lifts across Michigan or northern Ohio.
Further north track (00Z GFS) would draw warmer air further
northward, and cause a fast changeover to rain to a portion of
Southeast Michigan while more southerly track of the GEM would favor
all snow. There are also large differences with QPF between the GFS
and the Euro/GEM, with the GFS more than an inch higher as it taps
into better plume of warmth and moisture. Questions with QPF and
precip type lead to even more questions when it comes to snow
amounts. There is high confidence that precipitation will initially
start out as snow Friday night as the elevated portion of the warm
front lifts into Lower Michigan, as arctic air remains fully
entrenched over the area. We could see several inches area-wide
overnight. Any changeover to rain would occur on Saturday before
colder air wrapping into the backside of the system changes precip
back to snow Saturday night. Regardless of precip type, it will at
least be noticeably warmer on Saturday with temperatures reaching
the upper 20s to possibly mid 30s. Warm-up will be short-lived
however as very cold air fills back in behind a cold front for the
second half of the weekend, dropping temps Sunday and Monday back
into teens for highs.

MARINE...

A cold front will traverse Lake Huron this morning before advancing
across Lake Erie this afternoon. Despite a marginally stable over-
lake profile, the prefrontal southwest gradient is strong enough to
support gusty winds across the lakes (Gravelly Shoal actually
reporting a gust to 31 knots at 1 AM). Winds will gradually veer to
the west with the passage of the front. Post frontal cold air
advection will sustain gusty winds (around 25 knots) through
tonight.

The passage of a secondary cold front into the northern Great Lakes
on Wednesday will mark the arrival of much colder air. The
increasing gradient and deep mixed layer will support gale force
wind gusts. A prolonged period of gale force wind gusts (lasting
through Thursday) is expected with this arctic air outbreak. The
persistent gradient supporting these gales will be the result of
surface troughing parked over the northern Great Lakes and arctic
high pressure centered over the Midwest. The probabilities in gale
force wind gusts are high Wednesday and Thursday. There is still
some uncertainty as to how quickly the winds will increase Wednesday
morning. So the gale watch will remain in tack through one more
forecast cycle. The strong winds combined with the arctic air will
also cause some freezing spray.
