URGENT - MARINE WEATHER MESSAGE
National Weather Service Detroit/Pontiac MI
343 AM EDT Mon Oct 15 2018

...NORTHWEST GALES TODAY FOLLOWED BY SOUTHWEST GALES TUESDAY...

.An active period of marine wind and wave conditions is set to unfold 
through mid week as two main low pressure systems and associated 
fronts affect the central Great Lakes. The first is a cold front 
moving through early today which brings gusty northwest wind to all 
marine areas. A Gale Warning remains in effect for the open waters 
of Lake Huron north of Harbor Beach and a Small Craft Advisory 
remains in effect for all other marine areas.

A diminishing trend of only a few hours occurs overnight as the next 
low pressure system approaches the northern Great Lakes. Northwest 
wind quickly backs to southwest and strengthens rapidly to gales 
again by early Tuesday morning. The cold air mass remains in 
residence during this time and maintains an unstable thermal profile 
over Lake Huron and Saginaw Bay as the wind ramps up. Southwest wind 
gusts of 35 to 40 knots are likely again across the open waters of 
Lake Huron north of Harbor Beach but also including Saginaw Bay. The 
Gale Warning is therefore extended through Tuesday for Lake Huron 
and transitions from a Small Craft Advisory tonight to a Gale 
Warning Tuesday for Saginaw Bay. The associated cold front moves 
through the central Great Lakes Tuesday night with northwest wind 
gusting mainly around 30 knots with a few gusts to marginal gales 
possible over central Lake Huron through Wednesday.

URGENT - MARINE WEATHER MESSAGE
National Weather Service Detroit/Pontiac MI
352 PM EDT Mon Oct 15 2018

...Gusts to gales through Tuesday...

.Post frontal westerly winds gusts will top out around 35 knot gales 
across much of Lake Huron late this afternoon and early this evening 
within strong post frontal cold air advection. There will be an 
overall weakening trend to the winds overnight as the gradient 
relaxes and the cold air advection eases. 

Another cold front will approach the Great Lakes from the west 
Tuesday morning. The result will be a backing of the winds to the 
southwest. Ample low level cold air will support decent over-lake 
mixing depths so that wind speeds will increase. There is reasonably 
high confidence that gusts will once again top 35 knots gales on 
Lake Huron, with the strongest winds expected across Saginaw Bay out 
into the middle of Lake Huron. The cold front will traverse Lake 
Huron Tues afternoon and evening, resulting in a veering of the 
winds to the west-northwest. The front will mark another push of 
cold air, keeping winds elevated through the day Wednesday. There is 
actually another chance for gale force gusts on the open waters of 
Lake Huron Wednesday. A fairly active weather pattern in terms of 
wind speeds will persist across the lakes well into the weekend as 
yet another strong cold front is forecast to impact the area Friday 
night.

URGENT - MARINE WEATHER MESSAGE
National Weather Service Detroit/Pontiac MI
350 AM EDT Tue Oct 16 2018

...SOUTHWEST GALES TODAY AND NORTHWEST GALES POSSIBLE WEDNESDAY...

.Northwest gales over the open waters of Lake Huron have settled down 
to around 30 knots during the early morning. The wind will now shift 
southwest and increase again into the 35 to 40 knot gale range 
through today affecting mainly Saginaw Bay along with central and 
northern Lake Huron. Gale Warnings remain in effect through this 
evening for Saginaw Bay and Lake Huron north of Harbor Beach. Small 
Craft Advisories remain in effect for all other marine areas through 
western Lake Erie. 

Gales subside to gusts around 30 knots by mid evening through the 
overnight as the pressure gradient relaxes in the vicinity of the 
cold front moving through the central Great Lakes. However, wind 
veers and strengthens Wednesday with northwest gales possible 
once again. Given the lengthy break tonight, and some uncertainty 
on timing and magnitude Wednesday, a Gale Watch has been issued 
for central and northern Lake Huron for Wednesday into Wednesday 
evening. High pressure then builds into the Ohio valley and 
southern Great Lakes for a short time through Thursday before the 
active weather pattern resumes with another strong cold front 
Friday night.

What forecasters said that day

The local office's own words before this gale warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Detroit, MI wrote its last area forecast discussion before this gale warning went out at Oct 15, 3:29 AM EDT, 14 minutes earlier.

Area forecast discussion, Oct 15, 3:29 AM EDT, 14 minutes before
Area Forecast Discussion
National Weather Service Detroit/Pontiac MI
329 AM EDT Mon Oct 15 2018

.DISCUSSION...

Extended stretch of below normal temperatures will define this
forecast period, as the great lakes remain under the influence of
larger scale troughing reinforced by a series of shortwaves of north
pacific origin. One such wave now anchored over western lake
superior will accelerate northeast while deepening over the next 24
hours. Attendant cold front on track to sweep across southeast
Michigan this morning as the greater height falls spill into the
region. While stronger mid level forcing will reside to the north in
closer proximity to the mid level circulation trajectory, the
combination of modest frontal forcing and an uptick in cva will
maintain the potential for shower development locally throughout the
morning period. Precipitation potential diminishes quickly by midday
as both the moisture depth and available forcing wanes. The ensuing
increase in cold air advection augmented by a strengthening pressure
gradient within the immediate wake of a deepening low-mid level
system will then result in a period of gusty westerly conditions mid
afternoon into the evening. Recent model and probabilistic guidance
maintain gust potential in the 30 mph range. Limited diurnal
temperature response expected given the timing and strength of the
advective process. This will keep daytime temperatures parked
generally within the upper 40s to lower 50s range.

850 mb temperatures will bottom out near -5C as cold air advection
ceases tonight, translating into a cold Tuesday morning. The overall
magnitude of the radiational cooling potential does carry some
uncertainty yet, owing to the likelihood that the near surface layer
remains modestly mixed /5-7 kt west to southwest wind/ and the
potential for lake Michigan stratus to funnel downstream early
Tuesday morning. With that said, pure magnitude of the resident
thermal profile would suggest lows approaching the freezing mark are
attainable. Freeze/frost headlines certainly in play for tonight, but
will afford the daycrew the opportunity to access more near term
trends before delineating an appropriate headline if necessary.

Shortwave energy streaming across the northern great lakes will draw
another cold front across southeast Michigan late Tuesday. This
yields a brief window of opportunity for weak pre-frontal warm air
advection during the day. Any early day lake stratus mixes out
within this pattern, before thicker mid cloud accompanies the
frontal boundary late. Low level moisture recovery remains non-
existent given the quick turnaround from the fropa today, so
precipitation potential with this frontal passage remains minimal.
Gusty conditions once again during the daylight period, with
southwest winds gusting 30 to 35 mph by afternoon - strongest north
of I-69.

Period of strong height falls into the existing mean trough axis
Tuesday night into Wednesday will yield a solid reinforcing shot of
colder air for the midweek period. Temperatures within the 850-925
mb layer projected to run 2-3 degrees colder than the cold shot
noted today/tonight. This will keep daytime temperatures Wednesday a
good 10 degrees below normal. Potential for some influence of high
pressure building over the Ohio valley lends confidence for a greater
radiational cooling opportunity Wednesday night - assuming clouds
clear. Coldest conditions this forecast period likely noted Thursday
morning given the environment, with a more widespread distribution of
lows at/below freezing.

&&

.MARINE...

An active period of marine wind and wave conditions is set to unfold
through mid week as two main low pressure systems and associated
fronts affect the central Great Lakes. The first is a cold front
moving through early today which brings gusty northwest wind to all
marine areas. A Gale Warning remains in effect for the open waters
of Lake Huron north of Harbor Beach and a Small Craft Advisory
remains in effect for all other marine areas.

A diminishing trend of only a few hours occurs overnight as the next
low pressure system approaches the northern Great Lakes. Northwest
wind quickly backs to southwest and strengthens rapidly to gales
again by early Tuesday morning. The cold air mass remains in
residence during this time and maintains an unstable thermal profile
over Lake Huron and Saginaw Bay as the wind ramps up. Southwest wind
gusts of 35 to 40 knots are likely again across the open waters of
Lake Huron north of Harbor Beach but also including Saginaw Bay. The
Gale Warning is therefore extended through Tuesday for Lake Huron
and transitions from a Small Craft Advisory tonight to a Gale
Warning Tuesday for Saginaw Bay. The associated cold front moves
through the central Great Lakes Tuesday night with northwest wind
gusting mainly around 30 knots with a few gusts to marginal gales
possible over central Lake Huron through Wednesday.

.PREV DISCUSSION...
Issued at 1145 PM EDT Sun Oct 14 2018

AVIATION...

Efficient 925-700mb system relative isentropic ascent is leading to
midcloud formation over much of Lower Michigan. The strongest of
warm advection support will miss Southeast Michigan to the southeast
between 06-09Z. Synoptic scale forcing will strip out of Wisconsin
and U.P. of Michigan lifting into NW Ontario. Most favorable timing
for light precipitation over Southeast Michigan will be during the
08-14Z timeframe as leftover frontal precipitation is dragged across
the area. Conditions are expected to remain in the MVFR category as
residual dry air proves pesky in the lowest 2000 ft. Rapid dry air
advection will occur during the late morning between 5.0 and 20.0
kft agl ending precipitation potential. Northwest winds will kick in
post cold front ranging between 15-25 knots during the afternoon.

For DTW...Clouds will now lower steadily with light rain chances
between 08-16Z.

DTW THRESHOLD PROBABILITIES...

*  Low in ceilings aob 5000 feet this evening, then high late
   tonight into Monday morning.
