Area Forecast Discussion
National Weather Service Marquette MI
401 PM EDT Tue Mar 18 2025

.KEY MESSAGES...

-A late-season winter storm will bring heavy snow and strong
 winds to portions of Upper Michigan Wednesday and Wednesday
 night with the worst conditions starting in the late
 afternoon/evening hours. The combination of high winds and
 heavy, wet snow will result in difficult travel conditions and
 potential power outages.

-Light snow Wednesday morning will become moderate to heavy
 into the afternoon and evening, with rates of 1-2"/hr expected
 in the heaviest bands.

-Snow will become more fluffy in the evening, leading to
 possible whiteout conditions, especially near the Lake Superior
 shorelines. Travel will be very difficult.

&&

.SHORT TERM /THROUGH TONIGHT/...
Issued at 127 PM EDT Tue Mar 18 2025

Early afternoon water vapor and 500 mb RAP analysis shows mid/upper
level moisture increasing into the Upper Great Lakes amid confluent
flow. Deep southern stream trough that will be responsible for our
next weather system is currently pushing through the Desert
Southwest, while a northern stream shortwave is crossing the
Canadian Rockies. At the surface, low pressure is emerging onto the
central Plains, while a ridge of high pressure is located from
around Lake Nipigon to James Bay.

As the low continues to eject off of the Plains, weak bands of
isentropic lift will set up in the vicinity of the UP. However,
forcing is expected to be weak through tonight, and drier air
draining from the high to the north should keep any precipitation to
nuisance levels at most. This is currently manifest by virga on area
radars. The threat of any freezing rain overnight appears to have
lessened relative to prior forecasts, but a few patches of freezing
rain or freezing drizzle can't be ruled out around interior portions
of Alger/Marquette and back toward Iron/Dickinson. This does not
appear to warrant any advisories but will monitor for the need of
any short-fused SPS. With saturation aloft, seeder-feeder processes
may result in p-type being rain or snow instead of freezing rain.
Lows tonight mainly in the upper 20s to low 30s.

&&

.LONG TERM /WEDNESDAY THROUGH TUESDAY/...
Issued at 400 PM EDT Tue Mar 18 2025

The anticipated late season winter storm begins to take shape
tomorrow as a deep trough swings out of the Rockies, reflecting a
~987 surface low pressure somewhere along the IA/MO border by 15z
Wednesday morning. The low lifts northeast reaching southern Lake
Michigan by the evening, increasing PoPs as the f-gen circulation
shifts northward. Though not as pronounced as previous model
guidance suggested, a NE-SW thermal gradient will start off
precipitation as rain or a wintry mix across the south and east
closer to Lake Michigan before transitioning to snow as colder air
wraps into the area.

Global models have trended towards a flatter upper level wave
interacting with the opening Colorado low, leading to a slightly
weaker surface low elongating into southern Michigan early Thursday.
This places the heaviest QPF axis a bit south and east than
previously forecast, highlighted well by the 12z CAM guidance, which
decided to take a significant shift southeast, further decreasing
confidence on snowfall amounts over the west and Keweenaw. At the
same time, this shunts the encroaching midlevel warm nose further
south east, decreasing freezing rain accumulation potential. Latest
HREF and NBM probabilities for 0.01" of freezing rain have lessened
to below 30% (basically 0% in the NBM) Wednesday afternoon. As for
snowfall totals, there is still a high amount of uncertainty as model
trends continue their shift south and east. The west and Keweenaw
could only see a few inches, but depending on the overnight guidance
its possible they could remain dry. Elsewhere, a heavy band of snow
is likely across the central UP, and in combination with
upslope/lake enhancement could potentially see upwards of 12-15" by
12z Thursday, though the latest ensemble trends are becoming
unfavorable for this solution.

Interestingly, there is a signal for some CSI (conditional symmetric
instability) release atop the south-central U.P. during the
afternoon and evening hours where CAMs depict negative theta-e lapse
rates and EPV slightly below zero in a saturated layer near the 700-
600mb fgen max. This could provide a slight enhancement to precip
rates and additional dynamical cooling, quickening the transition
from mixed precip to snow. If this occurs after the transition to
snow, a period of heavier >1" snowfall rates is possible. This may
be outlined in the latest 12z HREF run, where probability for >1"
snowfall rates increases >60%.

Impacts are increasingly likely with heavy, wet snow possible
accompanied by gusty winds up to 30-40 mph; there is a 30-60% chance
for wind gusts exceeding 40 mph in the Keweenaw and east half,
particularly near Lake Superior. With the bulk of snow falling as
wet snow, primary impacts are expected to be difficult travel and
potential power outages with gusty winds, however a brief period of
significantly reduced visibilities Wed evening over the west and
overnight into Thursday is possible as snow becomes dry and fluffier.

High pressure building in from the W on Thu dries out lingering lake
enhanced showers over the E by the evening hours with dry weather
likely carrying into Fri. Beyond the midweek system, PoPs increase
late in the day Fri into Sat as a mid level trough dives SE over the
Upper Great Lakes and another trough quickly emanates off the N
Rockies. Additional chances for precip is anticipated early next
week with another trough tracking off the N Rockies.

&&

.AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/...
Issued at 127 PM EDT Tue Mar 18 2025

Low (IFR/LIFR) cigs at the start of the TAF period expected to rise
somewhat to MVFR for the remainder of the afternoon. CMX/IWD could
rise to VFR overnight as well, with SAW likely stuck at MVFR and
trending back to IFR. There is a 20-30% chance for light snow at the
terminals during the overnight hours as well, and about a 10% chance
for freezing drizzle at SAW 06-12Z, but confidence too low to
mention in the TAFs. Strong low pressure system organizing to our
south will bring steadier snow to SAW starting between 12-15Z Wed,
resulting in a return to IFR vsby, although the heaviest snow won't
occur until after 18Z. IWD/CMX will be more on the periphery of the
snowfall, so PROB30s were used 12-18Z. Northeast winds will increase
with gusts to 25 kt 12-18Z Wed.

&&

.MARINE...
Issued at 400 PM EDT Tue Mar 18 2025

Northeast winds across the lake increase to 20-30 kts tonight as a
strong low pressure approaches the Great Lakes. Winds gradually back
north Wednesday afternoon through Wednesday night, increasing up to
gales to 35-40 kts over the eastern two thirds of the lake. The
strongest winds are expected over the east half where there is a 50%
chance for high end gales up to 45 kts, particularly near the
southern shores. Gales likely fall off by Thursday afternoon as
winds back west. 15-25 kt winds back southwest for Thursday night
and Friday. Winds quickly veer northwest Friday evening, increasing
to 20-30 kts through Saturday morning behind a cold front. There is
a 40-60% chance for gales to 35 kts behind this front Friday night
into Saturday with the strongest winds expected along the
international border. Winds likely settle below 20 kts again
Saturday night, remaining 20 kts or less the rest of the weekend.

Otherwise, some light freezing spray is possible late Wednesday
night through Thursday, primarily over the east half of the lake.
