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 Apr 8, 1:49 PM EDT, 1 hour 36 minutes earlier.

Area forecast discussion, Apr 8, 1:49 PM EDT, 1 hour 36 minutes before
Area Forecast Discussion
National Weather Service Gaylord MI
149 PM EDT Wed Apr 8 2020

.UPDATE...
Issued at 1052 AM EDT Wed Apr 8 2020

Strong April sun working its magic...helping steadily scour out
the low overcast and fog, especially across northeast lower
Michigan. Expect this trend to continue for several more hours
yet, with clouds hanging on longest across eastern upper Michigan.
Developing upstream cold front and mid level wave still look to
drive an expanding area of showers into our area late this
afternoon and evening, with most areas likely seeing at least some
light rain amounts. Temperatures will continue to warm, helped
along by that sun, with much of the interior of northern lower
making a run at 60 degrees, or even a bit warmer.

&&

.NEAR TERM...(Today through Tonight)
Issued at 304 AM EDT Wed Apr 8 2020

...Warm today, showers late then turning colder tonight...

High Impact Weather Potential...Low.

Primary Forecast Concerns...How warm it will turn today and the
timing of showers later today.

Big changes are on the horizon but not before a relatively warm
day today. Low pressure moving by to our north will draw up
moisture from our south and west out ahead of a strong cold front
which will move across the region this evening. This is expected
to lead to a period of rain showers from late this afternoon into
the evening hours. In the meantime, low clouds and fog are
expected to break up just after sunrise (some spots will continue
to see pockets of dense fog in the meantime). Temperatures should
be on the warm side, ranging from the lower 50s north to the
lower 60s south (get out there and enjoy it because temperatures
do not look like they will resemble anytime close to that anytime
soon). The rain showers should come to an end early tonight as
colder air filters into the region behind the departing cold
front. An upper level disturbance dropping in late tonight will
lead to chances for rain and even snow showers (as the cold air
becomes established). Lows tonight in the low and mid 30s.

&&

.SHORT TERM...(Thursday through Friday Night)
Issued at 304 AM EDT Wed Apr 8 2020

Thursday through Friday night

...Chilly...

High Impact Weather Potential...Minimal.

Pattern Synopsis/Forecast and possible outcomes...12z/Thu when the
500 mb low sinks into Michigan, with a shortwave trough rotating
into the state as well. Temperatures look to get "cold enough" for
snow as the models soundings show most of the profile below
freezing, and the sfc layer just around the mid 30s, and wetbulbs
around freezing. So will have mainly snow or rain/snow mix for the
day on Thursday, then tapering off to flurries in the evening.
However, the 850 mb temperatures over the UP, Lake Superior and N
Lake Michigan look to be around -9C to about -10C. Will have to
watch for lake enhancement or lake effect snow, but with the dry air
in the 850-700 mb layer, will continue flurries/slight chance snow
into Friday morning. Friday, the potential for LES begins to
diminish through the afternoon as the 850 mb temperatures begin to
climb, as the 1000-850 mb wind ridge moves into the region ahead of
the next system. Friday night looks dry with the warming
temperatures and return flow.

.LONG TERM...(Saturday through Tuesday)
Issued at 304 AM EDT Wed Apr 8 2020

High Impact Weather Potential...Monday may have an accumulating
snow, but there is considerable uncertainty with the model tracks.

Extended (Saturday through Tuesday)...Saturday looks to be dry as
the system in the southern plains begins to advance into the central
part of the country. The rain breaks out in Lower Michigan
sometime late evening (like after 03z/Sun) and then spreading
across the state by 18z/Sunday. The rain is off and on through
MOnday on the ECMWF as the dry slot moves into the forecast area,
and dries us out before the 500 mb low drags the cold air and
precipitation back in. The GFS, on the other hand, keeps the low
centered in such a way that the precipitation continue through
Tuesday morning. By the looks of it, LES will be possible through
Wednesday morning.

The models have again gone all over the place with this pattern. So
will not be surprised with the changing forecast details. Right now,
the models have a 400 mile difference in the sfc low track Monday
morning.
