Area Forecast Discussion
National Weather Service Marquette MI
253 PM EDT Tue Sep 21 2021

.SHORT TERM...(This evening through Wednesday)
Issued at 253 PM EDT TUE SEP 21 2021

Latest RAP analysis and water vapor imagery show one shortwave
moving slowly w-e across the Upper Great Lakes this afternoon. As
this shortwave pushes e of the area late afternoon/early evening
expect any remaining isolated afternoon showers to end. Another
shortwave farther upstream over southern Manitoba/nw Ontario is
expected to move across the Upper Great Lakes late tonight/early Wed
and bring another chance for some lake-induced showers into the
north central U.P.

Tonight and Wednesday, models suggest 850mb temps will fall
slightly, closer to 0-2C and considering Lake Superior water temps
are near 15-16C, these temperatures will be near the pure lake-
effect threshold for lake showers as model soundings indicate
saturation through roughly 5kft. As a sfc high pressure ridge builds
in from the west tonight, winds will turn northerly across the area
and become slightly convergent into the north central U.P. late
tonight. The combination of the lake induced instability, convergent
northerly winds and perhaps some weak forcing from the nw Ontario
shortwave moving across the area could spawn some light isolated
showers into eastern Baraga, Marquette and western Alger counties.
These showers could continue into Wed morning, but then ridging
building in behind the weak shortwave trough should put an end to
any showers by afternoon with a trend toward clearing skies.

Under clear to partly cloudy skies, expect min temps ranging from
the upper 30s interior west to mostly the lower to mid 40s
elsewhere. Highs Wednesday under a mix of sun and clouds will range
from the mid to upper 50s north to around 60s along the WI border
and south central.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 236 PM EDT TUE SEP 21 2021

Long term period continues to present a few opportunities for rain
showers. While there still exists some uncertainty in the
Thursday/Thursday night low lifting north out of the Ohio Valley,
guidance is starting to paint a much clearer picture than earlier
runs. High temps through the period look to be mostly in the 60s,
with Thursday being the coolest with highs close to 60. Overnight
lows look to range from the 40s near the lakeshores, to 40s and some
30s in the interior spots.

Ridging extending out of the northern Plains is progged to extend
into western Upper Michigan Wednesday night. This should help
support mostly clear skies early on in the west, which will translate
into a decent amount of radiational cooling. Models have been
consistent with this thinking and bring lows down into the 30s in
the interior west half and 40s by the lakeshores. Areas of frost are
looking probable in the interior west given the light winds. More
cloud cover is expected in the east thanks to a system lifting
northward out of the Ohio Valley toward Lake Huron. There, lows
should bottom out in the low 40s to near 40F.

The aforementioned system lifting out of the Ohio Valley is progged
to take on a negative tilt, then close off aloft as it lifts
northward. The surface low is expected to move through or near Lake
Huron Thursday and then into Ontario Thursday night. The exact
position and track of the low varies among the guidance, but the
western edge of the low's deformation zone is expected to bring rain
showers to the east through the day and gradually end through the
night. How far west this will extend is where the uncertainty lies.

As the low lifts out, brief ridging will shift eastward through
Friday night before the next upper level low dips southeast into the
region late Friday. Previous model runs either had this system
remaining an open wave, then quickly lifting out, or a close low
parking on top of the Upper Great Lakes for the weekend. Well, now
model runs now have honed on a solution with a mix of the two
solutions. Current thinking is for an upper level low dropping
southeast through the region and exiting by the later half of the
weekend. This suggests rain showers will progress west to east along
the low's cold front late Friday into Friday night with periods of
showers afterwards as a secondary front/trough and some lake effect
rain showers follow on Saturday. As the system lifts out on Sunday,
rain showers should gradually end west to east.

Issued at 135 PM EDT TUE SEP 21 2021

MVFR/VFR cigs at IWD/CMX/SAW are expected to lift to VFR toward
evening. Later tonight, model soundings suggest a developing
light convergent northerly wind may bring a MVFR cig back into SAW
with some light drizzle or isolated showers possible before
improvement to VFR Wed afternoon.

.MARINE...(For the 4 PM Lake Superior forecast issuance)
Issued at 253 PM EDT TUE SEP 21 2021

With the exception of a few localized gusts near gale, northwest
winds have subsided blo gales over the east half of Lake Superior.
East half winds will then subside into the 15 to 25 knots range
through much of tonight. Winds will remain less than 20 kts over the
west half of the lake through tonight. A low developing over the
Ohio Valley on Wednesday is expected to lift north-northwest towards
Lake Huron by Thursday. Depending on the track and strength of this
low, there could end up being some gale force gusts on the far
eastern lake Thursday. However, confidence is still low at this
point, so have decided to just mention that here rather than
explicitly include it in the forecast. Light winds over the west
half of the lake will persist through Thursday. A trough moving
across the region will cause westerly winds to increase to around 20
knots Friday into Saturday.
