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 Marquette, MI wrote its last area forecast discussion before this small craft advisory went out at Apr 4, 1:15 AM EDT, 3 hours 6 minutes earlier.

Area forecast discussion, Apr 4, 1:15 AM EDT, 3 hours 6 minutes before
Area Forecast Discussion
National Weather Service Marquette MI
115 AM EDT Sun Apr 4 2021

.SHORT TERM...(This evening through Sunday)
Issued at 321 PM EDT SAT APR 3 2021

Various satellite products support what anyone that's been outside
today already knows...a nice beautiful and mostly clear Saturday has
taken place across the forecast area today. With the ample sunshine
and 850mb temps ~2-4C, surface temps have climbed into the 60s in
the west except by the lakeshores and in the Keweenaw. There and in
the interior east, temps have climbed into the 50s. Daytime mixing
into an increasingly dry airmass has allowed RH values to drop into
the 20s in parts of the interior west. For the rest of the
afternoon, high res guidance supports a slug of upstream dry air
continuing eastward into the west and central parts of Upper
Michigan. As mixing decreases as the sun sinks lower though, RH
values should start to recover, but they should sink a little lower
here and there. I also wouldn't be surprised if RH less than 30%
across the west became more widespread.

Tonight, high pressure helping to support today's dry airmass will
continue to influence the region. Upstream, a shortwave and surface
low over Minnesota will slowly meander east, allowing WAA and
isentropic lift to build mid to high cloud cover over the west.
These should limit how cold it gets and keep most in the low to mid
30s. Where skies will likely stay clear in the east, lows could dip
into the 20s. Lakeshore communities should stay in the 30s.

Sunday, as WAA continues, expecting another warm and dry day. Much
of the west should eclipse the 60 degree mark, except in the
Keeweenaw. There mid-50s are expected. In the east, mainly low to
mid 50s are expected. Model soundings show a large vertical dry
sector underneath the clouds. While the clouds should limit mixing
potential, some daytime mixing should still allow drier air and
afternoon gusty winds of around 15 to 20 mph to mix down. RH values
in parts of the interior west could sink to near 25%, but most of
the region is expected to bottom out in the 30%s.

.LONG TERM...(Sunday night through Saturday)
Issued at 349 PM EDT SAT APR 3 2021

Models indicate a blocky pattern will persist over the North
Atlantic and Eastern Canada through much of the extended. Ensembles
then show the anomalously strong ridge over the North Atlantic
beginning to retrograde toward Hudson Bay for mid to late next week
which should lead to more of a split flow pattern across much of the
CONUS at that time. Main fcst challenge will revolve around the
models handling of a closed low which forms by midweek in southern
stream of developing split flow pattern and the potential impacts,
if any, of the low as it tracks into the western Great Lakes. In
general, expect above normal temperatures will prevail with
precipitation chances increasing mainly late Monday into early
Tuesday then falling somewhat Tuesday afternoon through the end of
the week.

Sunday night, models indicate a weak shortwave rippling through
broad mid-upper level ridging late in the day with a sfc response of
a weak inverted sfc trough nosing into the western fcst area.
However, air mass from NAM fcst soundings looks prohibitively dry
for rain to occur so will maintain dry fcst in grids into Sun night.
With more mid-level clouds fcst over the area, expect milder min
temps, generally in the upper 30s to lower 40s.

Late Monday into Tuesday, a stronger shortwave/closed low moving
from northern Manitoba toward Hudson Bay will result in a frontal
boundary getting pushed across the fcst area. Weak forcing and
limited or weak moisture transport ahead of the frontal boundary
should keep any developing rain showers light across the area. WAA
ahead of the frontal boundary may result in a slight increase in
high temps over the west half on Monday into the mid 50s to lower
60s, but weak CAA behind the boundary will lower max temps on Tue
into the upper 40s near Lake Superior to maybe the lower 60s near
the WI border south central.

Model uncertainty greatly increases by mid to late next week with
regards to track of closed low developing over the Central Plains in
split flow pattern. The 12Z GFS model brings the closed low north
into Upper Mi by Friday. This farther north solution seems to be the
outlier among deterministic models and even the GEFS emsemble. Both
the 12Z Canadian and UKMET take the closed low track to northern IL
or the IL/WI border by 12Z Fri and the 00Z ECMWF is even farther
south into central IL. Clustering of ensemble members and consensus
of deterministic models would support the track through northern IL
or IL/WI border. This more southern track solution would probably
support only light rainfall amounts into most of Upper Mi for mid to
late next week with maybe a better chance for periods of moderate
rainfall into south central portions. The latest 12z ECMWF has
trended farther north, more in line although not quite as north as
the GEFS mean solution. At any rate, model trends of this low track
will definitely be worth monitoring to determine the potential of
much needed rainfall for mid to late next week. Given model
uncertainty will utilize low chance model blended PoPs for the mid
to late week fcst.

.AVIATION...(For the 06Z TAFS through 06Z Sunday night)
Issued at 112 AM EDT SUN APR 4 2021

VFR conditions are expected through the forecast period with only
periods of mid and high clouds. South to southeast winds will
increase today and become gusty at times to near 20 knots in the
afternoon.
&&

.MARINE...(For the 4 PM Lake Superior forecast issuance)
Issued at 321 PM EDT SAT APR 3 2021

Weak northwesterly winds should filter across the remainder of the
lake though the afternoon hours as the pressure gradient relaxes
behind today's surface trough. Expecting these lighter winds to
continue overnight tonight and into the early part of Sunday
morning. High pressure building eastward into the James Bay region
as a system moves east through Minnesota will allow winds to
increase to 20-30 knots over parts of the north and western Lake by
Sunday afternoon and east into Monday night. Following the trough's
exit Monday night into Tuesday morning, winds should again return to
20 knots or less. A little further out, low pressure is progged to
develop in the Central Plains and track northeast toward the Great
Lakes. Northeast winds look to begin increasing to near 25 knots in
the western third of the Lake Wednesday.
