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 25, 7:00 PM EDT, 13 minutes earlier.

Area forecast discussion, Sep 25, 7:00 PM EDT, 13 minutes before
Area Forecast Discussion
National Weather Service Gaylord MI
700 PM EDT Fri Sep 25 2020

.NEAR TERM...(Through Saturday)
Issued at 347 PM EDT Fri Sep 25 2020

...Remaining warm, with increasing shower and thunderstorm chances...

High impact weather potential: Hazardous swimming conditions along
parts of Lake Michigan tonight into Saturday morning. Chance for a
few thunderstorms at times tonight into Saturday.

Pattern synopsis/forecast:

Relatively fast mid and upper level zonal flow found across the
northern Conus and southern Canada early this afternoon. Weak mid
level ridge axis across our neck of the woods, with dual shortwave
troughs located upstream...one pivoting east across North Dakota,
with another more impressive one punching into southwest Canada. At
the surface, weak cold front extending south from northern Manitoba
low pressure into Minnesota, with a maturing warm front extending
southeast from this low across Lake Superior into eastern upper
Michigan. Increasing warm air advection and a drying mid level
environment within strengthening southwest winds behind this front
overspread northern Michigan, bringing well above normal
temperatures and plenty of sunshine, especially for areas south of
the big bridge.

Mid and upper level flow regime begins to amplify tonight into the
weekend, made to do so by intense upper level jet punching off the
Pacific into the west coast and Intermountain West. This transition
punts current North Dakota wave northeast across Lake Superior
overnight, reaching western Quebec by Saturday afternoon. Attendant
Minnesota cold front makes steady progress east into Upper Michigan
tonight, steadily weakening in the process with detachment of its
mid level support.

Primary forecast concerns/challenges: Addressing shower and
thunderstorm potential tonight and Saturday.

Details:

As mentioned, upstream cold front makes steady east progress into
the northwest Great Lakes tonight, expected to stall and eventually
wash out vicinity eastern upper Michigan on Saturday as mid level
support completely detaches. Showers and thunderstorms will
initially expand and become better organized to our west this
evening, with overall intensity and organization of these showers
likely decreasing as they head east into eastern upper Michigan
later this evening and overnight as that mid level support
decreases. Shower threat will nudge southeast with time into
northern lower Michigan late tonight into Saturday. Still cannot
rule out a few rumbles of thunder as elevated instability
plume/elevated mid level lapse rates fold overhead. Still,
pronounced low level cap and greatly reduced deep layer forcing
should keep storms well below severe limits. In addition, above also
supports minimal shower coverage on Saturday, much much of the time
and most of the area likely remaining dry through the day.
Definitely another mild day, although more cloud cover will likely
prevent temperatures from reaching the values observed this
afternoon. Still, projected highs ranging from around 70 (eastern
upper) to upper 70s (south side of the sunrise side) are several
degrees above normal for this time of year.

&&

.SHORT TERM...(Saturday night through Monday)
Issued at 347 PM EDT Fri Sep 25 2020

High Impact Weather Potential: A few thunderstorms possible for some
Saturday night.

Pattern Synopsis:

Mainly zonal flow will be in place across the northern CONUS to
start the period before a shortwave digs from the Pacific NW into
the southern Great Plains by Monday, amplifying a longwave trough
centered over the middle of the country. At the surface, a cyclone
near 990 mb over Manitoba will gradually weaken as a second cyclone
develops over Ontario collocated with more favorable
divergence/ascent aloft. Embedded shortwaves/speed maxima are
expected to rotate through the main flow over the Great Lakes into
early this upcoming week. A relatively weak front looks to pass
through northern Michigan on Sunday before a stronger cold front
sweeps across in the late Sunday night/early Monday time frame,
ushering in colder weather for the Great Lakes.

Forecast/Details:

A cluster of thunderstorms look to initiate along a warm front
draped across central Wisconsin Saturday afternoon, eventually
trekking across Lake Michigan and into eastern upper and Tip of the
Mitt Saturday evening/night amidst strong SW/WSW flow aloft. These
storms are expected to be elevated as forecast soundings display
steep mid-level lapse rates producing around 1,000 J/kg MUCAPE
overtop of capped/stable low-levels. With strong upper-level shear
in place, an organized storm or two capable of producing hail can't
be ruled out, but is not anticipated. These storms should vacate to
the east by Sunday morning.

Additional rain chances arrive Sunday late morning/afternoon along
and behind a cold front moving across the state. While relatively
weak, this should wipe favorable low-level moisture from the region.
Rain chances are expected to continue into Monday with continued
warm air advection/frontogenetical forcing setting up over the area
while slowly moving eastward. This will bring more of on-and-off
rain showers to the area as opposed to a washout as rain totals are
expected to be less than 0.25" for most. A second front swings
across the Great Lakes late, likely early Monday, ushering in colder
temperatures across the region. Otherwise, high temps in the low to
mid 70s are expected on Sunday before cooling off into the upper
50s/low 60s on Monday.

.LONG TERM...(Monday night through Friday)
Issued at 347 PM EDT Fri Sep 25 2020

High Impact Weather Potential: Low...Cool temps arrive this
upcoming week

Amplified longwave troughing is expected to encompass much of the
central CONUS through the upcoming workweek. Embedded
shortwaves/speed maxima could provide favorable ascent to support
relatively weak cyclone development to our north and east, aiding
continued northwest flow across the Great Lakes into the end of the
week. With a colder air mass being funneled in over the relatively
warm lake waters, lake effect rain showers are possible across
typical northwest flow areas for a chunk of the workweek. The main
story of this upcoming week will be the cool afternoon temperatures
as amplified troughing sits overhead into next weekend. Highs in the
mid 50s are anticipated across much of the area on Tuesday and are
only expected to get colder during the week. By Thursday, highs
could struggle to reach above 50 for most.

&&

.AVIATION...(For the 00Z TAFS through 00Z Saturday evening)
Issued at 700 PM EDT Fri Sep 25 2020

A cold front will sweep thru Wisconsin and into Northern Michigan
tonight...and will then stall over our area thru Saturday. Dry wx
and VFR conditions will continue thru much of tonight for all
Northern Lower Michigan TAF sites despite increasing and lowering
cloud cover. Chances of showers will develop late tonight into
Saturday along and ahead of this front...but overall VFR
conditions will prevail. Thunderstorms are also possible but the
chance is too small to specifically include in the TAF forecasts
for now. LLWS will develop tonight and persist into Saturday
morning as low level winds strengthen ahead of this system.
Surface winds will remain from the south at 10 to 15 kts with some
higher gusts expected on Saturday.

&&

.MARINE...
Issued at 347 PM EDT Fri Sep 25 2020

Gusty south and southwest winds into this evening will gradually
subside overnight into Saturday. Southerly winds increase quickly
heading into Sunday evening and night as low pressure races across
the northern Great Lakes. Another round of small craft advisory
conditions are likely during this period on several of our nearshore
waters. Southwest winds, at times gusty, continue into Sunday. A few
showers and thunderstorms are expected at times through this
weekend, although much of the time will remain dry.
