What forecasters said that day
The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Gaylord, MI wrote its last area forecast discussion before this small craft advisory went out at Sep 14, 9:09 PM EDT, 1 hour 20 minutes earlier.
Area forecast discussion, Sep 14, 9:09 PM EDT, 1 hour 20 minutes before
Area Forecast Discussion
National Weather Service Gaylord MI
909 PM EDT Mon Sep 14 2020
.UPDATE...
Issued at 909 PM EDT Mon Sep 14 2020
High pressure is over Lk Huron this evening. Minimal water-based
clouds present (one lingering cu patch near Lewiston), but plenty
of haze/smoke well aloft. Strong warm advection is getting
underway in the western Great Lakes, with expanding high-based
stratocu there. Leading edge of this is still west of MBL/
Frankfort. Near-term guidance is reasonably aggressive in
eventually bringing this cloud cover east. Have increased cloud
cover overnight (especially late) into Tue morning. The bulk of
any actual precip will clearly be north of upper MI. Most (but not
all) of recent CAMs keep eastern upper MI dry, though the 18Z Nam
does spit out some QPF. A small chance for showers and perhaps a
thunderstorm very late tonight/Tue morning is still reasonable in
eastern upper MI.
Have lowered min temps in the se, with some spots near W Branch
and Hale dipping into the upper 30s before warm advection and
cloud cover increases.
&&
.NEAR TERM...(Through Tuesday)
Issued at 338 PM EDT Mon Sep 14 2020
...Gusty winds return for Tuesday...
High Impact Weather Potential: Gusty southerly winds develop
Tuesday leading to marine related issues.
Pattern Synopsis/Forecast: Larger scale ridge trough pattern remains
dominant across the northern half of the CONUS with strong W/NW
mid-upper level flow stretching from southwester Canada and the
northern Rockies dipping into the Great Lakes. Expansive smoke
plume from the western CONUS wildfires caught up in the strong
flow extends across the northern Plains into the Midwest/Great
Lakes region and further to the mid Atlantic, leading to a thin
milky overcast appearance.
At the surface, large expanse of high pressure is centered over
northern Michigan. Along with deep layer dry air, we've had a
fair amount of smoke filtered sunshine today...although a bit
more heating of the day Cu did manage to develop and fan out
across northern Lower Michigan.
Surface high pressure will migrate into the eastern lakes region
tonight and to the mid Atlantic coast on Tuesday, while low
pressure and associated warm front develops through the northern
Plains and eastward into the northern Great Lakes on Tuesday.
Tight pressure gradient between these two systems will lead to
strong S/SW warm/moist advection flow developing across the
region starting late tonight and persisting through Tuesday.
Details: Increasing S/SW flow will begin driving axis of higher
theta-e air into the Upper Midwest this evening and across the
western Great Lakes into Canada overnight into Tuesday. Strongest
theta-e advection/moisture convergence is still looking to drive
across the U.P./Lake Superior region later this evening and
overnight and eventually into Ontario on Tuesday...with a round of
showers sliding across Lake Superior, just skirting parts of
eastern Upper Michigan early Tuesday morning. Guidance has trended
precip just a little further northward, but I'll keep our going
lower chances of showers going for now. Elevated thunder not out
of the question either as plume of steep lapse rates aloft (>7C/Km
700-500 MB layer) punches across the U.P.
Isolated-scattered shower chances linger into Tuesday morning. But
most if not all of the northern Michigan will end up punching into
the dry warm sector with +18C to +20C H8 air spreading across the
region. A good amount of sunshine again anticipated (smokey skies
notwithstanding) and temperatures warming well into the 70s. But,
gusty winds will be an issue as core of 40 to 50 knot low level
winds point into the region. Strong warm advection and a
pronounced inversion around 900 MB will curtail mixing/gust
potential to some degree. But gusts of 25 to 35 mph certainly look
attainable with which will lead to marine related issues and
headlines (gales/beach hazards and lakeshore flooding).
&&
.SHORT TERM...(Tuesday night through Thursday)
Issued at 338 PM EDT Mon Sep 14 2020
...Cold front to bring showers late Wednesday into Thursday...
High Impact Weather Potential: Minimal.
Synopsis/Forecast: Troughing pushes into Hudson Bay Tuesday night
with an 80-100kt upper level jet sagging south into the Great Lakes.
At the surface gusty south-southwest winds will continue into the
evening hours with the pressure gradient remaining tight as a
surface low treks into southern Ontario. The associated front starts
pushing south across our area Wednesday morning. There is only a
narrow corridor of decent moisture and dynamic lift ahead of a PV
anomaly scooting by just to our north, but nevertheless rain showers
are still possible as the front moves south through the day.
Wednesday night looks to dry out with drier air settling in ahead of
the next surface high. A cold pool at 850mb (0 to -2C) sinks down
from the north early Thursday morning, and remains in place into
Friday. This will give great overlake instability and lake effect
rain chances, but they will be fighting quite dry air. Thus decided
to keep very low pops downwind of the lakes.
High temperatures Wednesday bump up into the low to mid 70s for most
before the cold front comes sweeping through. Thursday will be much
cooler as CAA kicks in with temperatures in the upper 50s.
.LONG TERM...(Thursday night through Monday)
Issued at 338 PM EDT Mon Sep 14 2020
We head into a more progressive pattern late week and through the
weekend with a few waves transiting across the continent near the US-
Canadian border. At the end of the week the wave that will aid in
our cool temperatures will be rotating into Quebec. Another
transient wave quickly follows just behind it in northwest flow over
Ontario. Shortwave ridging quickly passes overhead Sunday with yet
another wave passing by early next week. Suffice to say there will
be low chances of showers off and on into early next week, but with
low confidence this far out will keep rain chances out of forecast
wording before Monday. Of more concern is how much cold air arrives
late week into the weekend...with guidance coming into much better
agreement with Friday night being the coldest of the week with a
>1030mb high moving over the area. Frost is possible each night
Thursday through Saturday, with the highest confidence for Friday
night. High temperatures will be meager, in the 50s, during this
time as well. We get into southerly return flow and warm things back
up late in the weekend into early next week.

.AVIATION...(For the 00Z TAFS through 00Z Tuesday evening)
Issued at 821 PM EDT Mon Sep 14 2020
VFR. LLWS late tonight PLN, and Tue evening at all sites.
High pressure over Lk Huron will continue to head east. Southwest
low-level flow will rapidly ramp up in the wake of the low. Some
showers and even thunderstorms could be spawned in upper MI late
tonight into Tue morning, though this should stay north of PLN.
Otherwise incoming airmass is relatively dry, so rain not
expected. Mainly VFR, though smoke/haze layer aloft will persist.
GUsty sw winds on Tuesday. LLWS works into PLN very late tonight,
just before surface winds really ramp up. LLWS at all TAF sites
Tue evening.

.MARINE...
Issued at 338 PM EDT Mon Sep 14 2020
Gusty south to southwest winds develop late tonight and persist
through Tuesday/Tuesday evening. Will go ahead and upgrade gale
watches to warnings for the Lake Michigan nearshore areas. Small
craft advisories will eventually be needed for the remaining Lake
Superior and Huron nearshore areas. Winds gradually diminish
heading into Wednesday although small craft advisories will
probably linger through Wednesday.
