GREAT LAKES ON THURSDAY, SUPPORTING LIGHT WINDS. THE EXCEPTION WILL 
BE ACROSS THE NORTHERN THIRD OF LAKE HURON WERE THE WESTERLY 
GRADIENT WILL SUSTAIN SOME MODEST WINDS. STRENGTHENING HIGH PRESSURE 
IS FORECAST TO EXPAND ACROSS THE UPPER MIDWEST THURS NIGHT INTO 
FRIDAY. ARCTIC AIR WILL BE ENTRENCHED ACROSS THE REGION, SUPPORTING 
UNSTABLE CONDITIONS OVER THE LAKES. THESE FACTORS WILL LEAD TO

...GALE FORCE WINDS POSSIBLE OVER LAKE HURON FRIDAY...

.WINDS WILL CONTINUE TO DIMINISH THIS MORNING AS LOW PRESSURE OVER 
HUDSON BAY PIVOT SLIGHTLY NORTH AND WEAKENS. ALL MARINE WARNINGS AND 
ADVISORIES WILL BE ALLOWED TO EXPIRE. MOST LOCATIONS WILL EXPERIENCE 
LIGHT WIND CONDITIONS INTO TODAY, BUT A DECENT WESTERLY GRADIENT 
WILL MAINTAIN GUSTS OF 25 TO 30 KNOTS OR THE NORTHERN THIRD OF LAKE 
HURON.

STRENGTHENING HIGH PRESSURE IS FORECAST TO EXPAND ACROSS THE UPPER 
MIDWEST TONIGHT INTO FRIDAY WHILE ARCTIC AIR WILL REMAIN ENTRENCHED 
ACROSS THE REGION, SUPPORTING UNSTABLE CONDITIONS OVER THE LAKES. 
THESE FACTORS WILL LEAD TO STRENGTHENING NORTHWEST WINDS. THERE IS A 
FAIRLY HIGH PROBABILITY THAT WIND GUSTS ACROSS PARTS OF LAKE HURON 
WILL EXCEED GALE FORCE ON FRIDAY AND A GALE WATCH REMAINS IN EFFECT 
IN ANTICIPATION OF THIS EVENTUALITY. THE COMBINATION STRONG
WINDS, LARGE WAVES, AND VERY COLD TEMPERATURES WILL ALSO CREATE 
AREAS OF FREEZING SPRAY, WHICH MAY BE HEAVY AT TIMES. WINDS WILL 
THEN WEAKEN DURING THE COURSE OF THE WEEKEND AS THE HIGH EXPANDS 
ACROSS THE GREAT LAKES.

Area Forecast Discussion
National Weather Service Detroit/Pontiac MI
400 PM EST Tue Mar 7 2017

.DISCUSSION...

A steady diminishing wind trend will follow clearing sky during the
late afternoon into the evening. The incoming cooler air under clear
sky will allow some wind decoupling along the idea of model
soundings. This will eliminate the gusty conditions while the
surface pressure gradient remains steep enough to maintain steady
gradient flow. Southwest wind holding in the 10 to 15 knot range is
expected to keep min temps above freezing across the region despite
the clear sky.

Full sunshine Wednesday morning will then give surface heating a
jump start and lead into the very windy conditions expected to
develop by late morning. Confidence remains high that a damaging
wind event will develop with no big changes to the large scale
weather features governing the event. Satellite imagery today shows
the upper level cold pool moving through the northern Plains as good
observational evidence of the upper trough leading the low level
cold air reinforcement from southern Canada. Surface observations
also report mid afternoon temperatures in the teens across North
Dakota with several peak wind gusts of 50+ kts. Members of the 12Z
model cycle have a good handle on this cold air reinforcement and
project it to arrive over Lower Michigan and deepen during Wednesday
morning based on the progress of the 850 mb -5C isotherm. This is
also a good measure of the dividing line between clear sky and
stratocu observed today over the northern Plains which sets up the
key opportunity for strong surface heating into the afternoon over
Lower Michigan during Wednesday. The incoming upper jet max will
take it from there and sharpen the mid level height gradient which
will then feed into strengthening the front and low level wind
field. This strengthening wind field is further illustrated in model
soundings that show development of a deep mixed layer through the
diurnal cycle which normally results in some evening and lowering of
wind speed through the layer as momentum is redistributed. In the
case of this event, wind speed is shown to increase through the
diurnal cycle despite the deep mixed layer. Model soundings across
solutions show 850 mb wind holding above 50 kts while the mixed
layer builds toward 750 mb during mid afternoon. This backs up
inhouse probability guidance that suggests frequent gusts reaching
50 mph as early as 9-10 am and lasting through early evening as late
as 8-9 pm, along with nonzero probability for reaching 60 mph. The
potential for a nearly 12 hour event with frequent 50 mph wind
gusts, and with gusts to 60 mph possible, warrants the high wind
watch for prolonged high wind impacts to power, structures, and
travel conditions.

The front will settle south of the Great Lakes Wednesday night into
Thursday while fast flow aloft transitions toward a more zonal
configuration. The zonal flow continues to exhibit smaller scale
waves with typically low predictability, the first of which is shown
to move through Thursday night. Chance POPs near the Ohio border
seem reasonable for this scenario which is likely to continue
shifting from run to run. This will lead to a more convincing surge
of surface high pressure and colder air for the weekend as the
transitional zonal flow begins a new round of trough development
over the Great Lakes. Below normal temperatures are then projected
to last into next week.

&&

.MARINE...

Winds will rapidly diminish this evening allowing small craft
advisories to expire before midnight local time. Gale warnings are
in effect for all area waters through the day Wednesday as southwest
flow rapidly re-intensifies. Strong southwest or west-southwest wind
will gust up to 45 knots. Due to relatively stable conditions over
the lake...the highest wind gusts are forecast to occur in the
nearshore zones. Offshore flow will force the highest waves to focus
over central Lake Huron and areas east of the International Border.
Unsettled marine conditions will persist through the week.

.PREV DISCUSSION...
Issued at 1211 PM EST Tue Mar 7 2017

AVIATION...

Back edge to MVFR cloud shield now approaching KMBS. Steady west-to-
east clearing expected through 20/21z with passage of cold front.
Gusts will hover around 30 kts through the daytime period with a few
localized higher gusts not out of the question...particularly near
FNT/MBS. Nocturnal stabilization will bring an end to gustiness 23-
00z. Clear skies and steady southwest gradient overnight will
rapidly intensify with the passing of an upper wave on Wednesday.
Strong pressure gradient will support SW wind gusts veering to WSW
through the day becoming sustained near 30 kts by the end of the
forecast period with gusts near 40 kts. Strengthening wind field
above the inversion could lead to a couple hours of wind shear
concerns toward sunrise.

For DTW...Wind shift to westerly anticipated by 19z, leading to
crosswind concerns as gusts hold steady around 30 kts. Wind will be
slightly more backed on Wednesday, but not enough to negate
crosswind concerns once again.

//DTW THRESHOLD PROBABILITIES...

* High for cigs aob 5kft through 20z.

* High for exceeding crosswind thresholds this afternoon and again
  by late Wednesday morning.
