Area Forecast Discussion
National Weather Service Marquette MI
737 AM EDT Mon Jun 21 2021

.SHORT TERM...(Today and tonight)
Issued at 503 AM EDT MON JUN 21 2021

WV imagery and RAP analysis indicated a mid/upper level trough from
Hudson Bay through northwest Ontario into the Upper Mississippi
Valley. A vigorous shortwave trough was located over northern
Wisconsin. Deformation/fgen associated with the shrtwv supported
lingering areas of rain through central and eastern Upper Michigan.
At the surface, a 994 mb low was lifting northeast through the
northern end of Lake Michigan. NNW winds were increasing with CAA
and a tightening gradient behind the low. Winds were already gusting
into the 30-40 mph range over northern Lake Superior and at KCMX.

Today, expect the rain showers to diminish early as the shrtwv and
supporting dynamics lift off to the northeast. Moist cyclonic
upslope nnw flow may sustain some light rain into portions of
northern Upper Michigan into the mid morning while the showers in
the east depart. Strong winds will also develop as 925 mb winds into
the 40-50 knot range develop this morning through mainly east
central Upper Michigan from KP53 to KISQ. Most high res models
suggest that with the CAA enough mixing and momentum transfer will
develop to support wind gusts to around 45 mph. So a Wind Advisory
was issued into this afternoon. Some higher gusts into the 30-40 mph
range will also be possible for adjacent portions of central Upper
Michigan, especially near Lake Superior. A Beach Hazards Statement
remains in effect for dangerous waves on Marquette and Alger county
beaches. Even with clearing and sunshine this afternoon highs will
struggle into the low to mid 50s near Lake Superior and to around 60
south.

Tonight, Diminishing winds and mostly clear skies early tonight may
allow temps to quickly drop. However, a weak clipper shrtwv
approaching overnight will bring increasing clouds and keep temps
from falling off as far and limit any frost potential. Isold light
showers or sprinkles may also be possible over the north.
Nevertheless, temps may still drop off into the upper 30s over
inland locations while readings in the lower to mid 40s are expected
near the Great Lakes.

.LONG TERM...(Tuesday through Sunday)
Issued at 332 AM EDT MON JUN 21 2021

Broad troughing extending southward out of an upper level low over
Hudson Bay will persist over the Upper Great Lakes Tuesday. The
result will be cooler than normal temperatures persisting. Weak WAA
will help warm things up though and 850mb temps early on near 1C are
progged to climb to near 4C by 0z Wednesday. This should translate
to highs in the 60s across the region. A passing shortwave coupled
with weak instability and increased convergence along the lake
breeze boundaries could support some shower activity across the
central and east. Vertical growth should largely be limited due to
capping around 12k ft; if the 300-500 j/kg MLCAPE is realized
though, some rumbles of thunder could be observed across the central
and east in the late afternoon and evening. Weak upper level ridging
will build in overnight and allow winds to become more southerly as
high pressure at the surface moves into the middle-Mississippi River
Valley. Overnight lows are largely expected to be in the 40s except
near the lakeshores where low 50s are possible.

The high will push toward the east coast through the day Wednesday,
allowing for stronger WAA and temps to climb into the 70s. Some weak
theta-e advection could kick off some shower activity across the far
south, but there's a good bit of uncertainty between the 0z guidance
and its more likely that any activity would stay south of the
forecast area.

Late Wednesday night, an elongated cold front is progged to dip
toward Lake Superior. Weak jet dynamics, healthy theta-e advection
and MLCAPE near 500j/kg will be enough to support shower activity by
sunrise in the west and central. Some thunderstorms can't be ruled
out as well. With this boundary slowly pushing eastward through the
day, there could be another opportunity for widespread rain across
the region. Ahead of the front, ~45kt LLJ at 925mb will be able to
support 25 to 30 mph southerly wind gusts in the east, particularly
near Lake Michigan, until late Thursday when the front exits into
Ontario.

Guidance the past few days has shown a consistent signal for an
upstream shortwave near the Dakotas to push eastward into the Upper
Midwest Thursday night. Through the day Friday, surface cyclogensis
would follow, with the low lifting through Lake Michigan and Lower
Michigan. With strong moisture advection with this system, there
could be another opportunity for rain. This track currently favors
the low's deformation zone moving over the central or eastern UP,
which could contribute to improving drought concerns. It should be
noted that there is considerable spread among the GEFS and GEPS
members on where the low tracks. If the low trends southward, then
it could end up being a dry Friday afternoon and evening.
&&

.AVIATION...(For the 12Z TAFS through 12Z Tuesday morning)
Issued at 736 AM EDT MON JUN 21 2021

IFR or low end MVFR conditions will improve to VFR/MVFR during the
morning and VFR this afternoon as drier air moves in behind a
cold front exiting the region. Winds behind the front will be
blustery from the northwest with gusts into the 30-35 knot range.
Winds then diminish around sunset Monday evening.

&&

.MARINE...(For the 4 AM Lake Superior forecast issuance)
Issued at 503 AM EDT MON JUN 21 2021

Unseasonably cold air wrapping around a strong low departing to the
northeast this morning result will result in strong NW winds. Gale
Warnings remain in effect for central and eastern portions of Lake
Superior into this afternoon. Winds will quickly diminish tonight
to 20 kts or less and remain that way through at least next Thursday.
