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 Marquette, MI wrote its last area forecast discussion before this gale warning went out at Mar 9, 6:51 PM EST, 2 hours 29 minutes earlier.
Area forecast discussion, Mar 9, 6:51 PM EST, 2 hours 29 minutes before
Area Forecast Discussion
National Weather Service Marquette MI
651 PM EST Tue Mar 9 2021
.SHORT TERM...(This evening through Wednesday)
Issued at 520 PM EST TUE MAR 9 2021
Mostly sunny skies and warm southerly winds allowed temperatures to
warm to 60F at several sites across the western U.P. this afternoon.
Warm southerly winds continue overnight ahead of an approaching
negatively tilted shortwave that is the main feature of interest in
the short term.
Southerly winds continue overnight ahead of a weak cold front
dropping south across the area Wednesday morning. The pre-frontal
air mass will be characterized by dew point temperatures well above
freezing, which is likely to produce fog over existing snow cover.
Additional lift provided by the passing cold front could produce a
brief period of dense fog. A moist post-frontal air mass will likely
prolong fog for areas favored by northerly upslope flow.
Synoptic scale lift increases on Wednesday as the negatively tilted
shortwave accelerates to the northeast resulting in a deepening sub-
1000mb low tracking across the CWA. Isentropic lift combined with
mid-level frontogenesis results in a swath of generally 0.50-1.00
inches of QPF that is expected to fall primarily as rain. However,
the lowest layer of the atmosphere is marginally cold enough for
precipitation type problems across higher elevations of the western
CWA. Raw model guidance (except the ECMWF) produces up to 3/4" of
QPF with surface temperatures below freezing indicating potential
for substantial ice accretion. However, warm antecedent
temperatures, a deep warm nose aloft, marginally cold boundary layer
temperatures, and potential for heavy precipitation rates suggests
relatively slow ice accretion rates. Colder air arriving late
Wednesday night will allow precipitation to change over to snow with
up to 2 inches expected by Thursday morning.
It's worth mentioning that recent HRRR and NAM-nest model guidance
has enough elevated instability to support an isolated clap of
thunder, but did not include it in the grids at this time. If
thunderstorms do develop Wednesday afternoon and evening then more
substantial hydro hazards may occur. However, current expectations
are for localized ponding on area roadways.
.LONG TERM...(Wednesday night through Tuesday)
Issued at 403 PM EST TUE MAR 9 2021
Long term period this shift will begin at 12z Thursday. At this
point the earlier mentioned surface low should over central Lake
Superior with the 700mb low over the Arrowhead with stout fgen
maximum/deformation zone extending into Ontario. Across western Lake
Superior, winds should become northwest, allowing for some moisture
with upslope enhancement into the Keweenaw to be possible into the
early afternoon. Initially a wintry mix will transition to snow as
the low lifts out and the cold air sufficiently cools the column. In
the central and east, any lingering precip in the morning would
likely be rain. Mid-upper level ridging will build in behind the
departing system allowing subsidence to eventually take over and
help clear out the skies by evening. Thursday highs should top out
in the upper 30s in the west and low 40s east. Overnight lows look
to be in the upper teens in the interior west half and 20s in the
east and by the lakeshores.
A shortwave looks to drop southeast through Lake Superior beginning
early on Friday. Strong CAA will help send 850mb temps down to
around -15 to -18C. Increasing low level lapse rates and sharp
pressure rises will allow for stronger winds aloft to mix down to
the surface. This will likely contribute to widespread westerly to
northwesterly breezy conditions. With stronger winds over eastern
Lake Superior, the northwest winds could build waves high enough to
create some lakeshore flooding east of Munising by evening. The
colder airmass will also result in more seasonable daytime highs in
the 30s with maybe some low 40s in Menominee County. With this front
being devoid of much moisture, the better precip chances look to be
on the north end of Lake Superior.
Little ambiguity is expected in the forecast across the region
through the weekend as a predominately dry air mass sits overhead.
With gradual warming at 850mb expected, daytime highs in the 30s on
Saturday will return back into the 40s west and south and upper 30s
north and east on Sunday. Through the weekend, an upper level low
will very slowly eject out of the central Rockies. The structure of
the feature is a little uncertain, but it appears to linger over the
Northern Plains on Monday. Guidance is suggesting some snow could
move into the region late in the day on Monday.
&&
.AVIATION...(For the 00Z TAFS through 00Z Wednesday evening)
Issued at 649 PM EST TUE MAR 9 2021
VFR conditions are expected to prevail for much of the night at
KIWD/KCMX/KSAW. In addition, low-level jet ahead of an approaching
cold front will also lead to LLWS. This LLWS will end from w to e
overnight into early Wed morning. Southerly flow advecting moisture
northward thru the night will bring MVFR cigs to all terminals prior
to daybreak with cigs lowering further to IFR by mid morning. Shra
will also spread quickly northward into the area during the morning.
During the aftn, IFR conditions will prevail at all terminals with
LIFR probably developing at KIWD/KSAW where an upslope wind
component will aid deteriorating conditions. There is a low
potential for -fzra at KIWD/KCMX late aftn as sfc temps may fall to
around 32F.
&&
.MARINE...(For the 4 PM Lake Superior forecast issuance)
Issued at 429 PM EST TUE MAR 9 2021
Southerly winds will of 20-30 knots are expected over the central
and eastern parts of Lake Superior this afternoon and tonight. Some
gale force gusts to 35 knots can't be ruled out, particularly for
higher reporting platforms. Winds will become light by Wednesday
morning and become northerly as the next system approaches from
the south. Northeast winds are expected to increase to gales over
the west as low pressure approaches and deepens over western WI.
The low should move through central Lake Superior during the
morning on Thursday, with winds becoming northwesterly lake-wide.
Some gale force gusts will be possible in the eastern part of the
lake by Thursday afternoon. A cold front will cross the lake on
Friday with a round of west to northwest gales possible.

A low pressure system lifting northeast across Upper Michigan Wednesday night will bring periods of moderate rainfall to the area Wednesday afternoon and evening. Rainfall totals of around an inch are expected. This rain, along with melting snow, could lead to some ponding of water on area roadways and in low-lying areas. Some minor rises on area rivers and streams could also occur. In addition, with frozen ground, water may find its way into basements. If your home has a sump pump, ensure it is functioning. Late Wednesday afternoon and evening, the rain may change over to a mix of snow and freezing rain. The best chance of freezing rain is over the highest elevations. However, there is some uncertainty on whether it will be cold enough for ice to form. If temperatures do fall to around freezing, there could be up to a tenth of an inch of ice accumulation, mainly on elevated surfaces.
