Area Forecast Discussion
National Weather Service Marquette MI
343 PM EDT Fri Aug 20 2021

.SHORT TERM...(This evening through Saturday)
Issued at 327 PM EDT FRI AUG 20 2021

Currently, we are looking almost like a complete repeat of
yesterday. Satellite imagery shows diurnal cu popping up in the U.P.
this afternoon as a dry high pressure ridge slowly makes its way
eastward. Some areas in the elevated terrain near Lake Superior (and
near southern Houghton County) are already around 90F! The only
saving graces right now is that RHs are around 40% in those areas
this afternoon and there is a light south/southwesterly breeze
across most of the area. Some light haze can still be seen across
the area, particularly in the east (as seen in the vertically
integrated smoke product in the HRRR smoke model).  This haze should
slowly leave the area tonight as a cold front approaches from the
west.

Tonight, expect temperatures to bottom out near the 60s across the
area, as some cloud cover associated with the cold front should
start rolling into the western CWA late. As the front approaches,
expect southerly winds to pick up from west to east. These winds
should bring some breezy conditions across the area ahead of the
cold front tonight and Saturday. Not expecting the rainfall
associated with the cold front to arrive in the far west until late
tonight. Given that only the NAM12km was showing some CAPE along the
frontal boundary during the overnight and early morning hours,
decided to cap thunder chances to slight until late Saturday
morning.

As the front progs eastward throughout the day Saturday, expect
cooler temperatures (mainly upper 70s) in the west behind the front,
whereas the far east (near Newberry) could see still see
temperatures approach the mid-80s.  Could still see some pockets of
low 80s along the downslope areas near Lake Superior, as the
downslope of southerly winds could raise temperatures to get over
80. Also, could see the low-80s in the south central too Saturday,
as the front isn't expected to arrive until the afternoon.
Thunderstorm chances improve throughout the day Saturday, as some
diurnal heating ahead of the cold front should increase instability
in central and eastern Upper MI. Not expecting severe wx, as the
front should be dying as it moves east; while MUCAPEs look modest
(around 1000-1500 J/kg) and bulk shear looks marginal for severe wx
(around 30 knots at most spots near the frontal boundary), because
the front is dying, the forcing mechanism to produce convection
should weaken with time. Therefore, while I think convection is a
definite possibility, I'm doubtful that the modest instability and
marginal bulk shear will be enough to overcome the loss of forcing
in the cold front to produce severe wx. The better forcing for
convection is expected north of us in northern Ontario, as the low
associated with this cold front lifts northeast towards Hudson Bay.
Thinking we will see more breezy conditions behind the cold front
Saturday, particularly in the Keweenaw Peninsula, as significant
height rises and temperature advection is expected; the Keweenaw
could see some wind gusts over 35 mph late tomorrow afternoon! The
wind direction behind the front is expected to be westerly.

.LONG TERM...(Saturday night through Friday)
Issued at 341 PM EDT FRI AUG 20 2021

Through the extended fcst period, models indicate mean troughing
over western Canada, and at times over the western CONUS, as a
series of shortwaves eject eastward across the northern CONUS and
Upper Great Lakes region in a progressive flow through next week.
Based on dynamics and available moisture, it looks like the more
promising chances for widespread showers would not be until mid to
late next week. Temperatures will fluctuate from near to above
normal through much of the period.

Beginning Saturday night into Sunday, models indicate any remaining
showers ending in the evening over the eastern portion of the cwa,
then dry, cooler and less humid conditions thereafter into Sunday as
sfc high pressure builds in quickly from the west behind Saturday's
shortwave/cold front. Min temps Sat night will fall back into the
more comfortable 50s for most locations. Sunday's max temps will be
closer to seasonal normals with highs in the 70s and dew points in
the upper 40s to mid 50s. Waves generated from fairly gusty nw-n
winds behind the front will likely warrant a high swim risk for
Alger County on Sunday.

The next shortwave moving across the Northern Plains on Sunday will
weaken as it lifts into northern Ontario by Monday morning. Models
show a weaker pcpn signal with this weakening wave compared to the
wave on Saturday. Even though GFS soundings indicate MLCAPE values
increasing to 500-1000j/kg Mon ahead of the front, warm nose of
nearly 17C temps aloft and fairly significant CIN may prohibit
convective development on Mon across much of the area. In the end,
the better chc of pcpn with this wave looks to be late Sun
night/early Mon over the w in association with an approaching, but
weakening 30 kt low-level jet. Otherwise, nothing more than low
chc/schc pops are warranted late Sun night/Mon. Max temps will rise
back into the lower to mid 80s most locations on Monday and Tuesday.

Latest models indicating perhaps a better signal for showers/t-
storms with the next shortwave due in late Tue into Wed. Trends
indicate better shortwave dynamics and stronger WAA/moisture
transport ahead of the system. With MUCAPE values approaching 1000-
1500 j/kg and deep layer shear 40-50 knots there certainly could be
some strong to marginally severe storms associated with this system.
High pressure building in behind this system should result in dry
and cooler conditions on Thursday.

Models certainly differ on the timing/strength details but there
does appear to be a pretty consistent signal that a broader, deeper
trough will dig in from the Northern Plains late next week/weekend
bringing more opportunities for rainfall.
&&

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 155 PM EDT FRI AUG 20 2021

VFR conditions are expected at all TAF sites until Saturday morning,
when a cold front begins to move through the area. MVFR cigs are
expected at each of the TAF sites Saturday as the front moves
through. Some shra and tsra are possible with this front. Also, it
seems that some LLWS is possible at each of the TAF sites tonight
and tomorrow as the front approaches (there is quite a difference in
wind speed and direction between the sfc and 2 kft aloft). Could see
some LLWS later Saturday and Saturday night too behind the cold
front as the winds pick up again due to CAA behind the front. Sfc
winds should remain southerly this afternoon and tonight. However,
they should start becoming westerly from west to east near the end
of the TAF period as the cold front moves through Upper MI. Expect
breezy conditions at each TAF site Saturday morning.
&&

.MARINE...(For the 4 PM Lake Superior forecast issuance)
Issued at 327 PM EDT FRI AUG 20 2021

Winds should remain 20 knots or less until this evening. As a cold
front approaches the lake tonight, expect southerly winds to
increase to 20 to 30 knots ahead of the cold front. As the cold
front moves through Saturday, expect the southerly winds to weaken
ahead of the front and for the westerly winds behind the front to
strengthen to 20 to 30 knots. Some westerly gale force gusts up to
35 knots are possible behind the cold front in the western and
central lake Saturday afternoon and evening. As the winds become
northwesterly Saturday evening, expect wind speeds to diminish; by
Sunday morning the winds should be 20 knots or less. The winds
should remain around 20 knots or less for the remainder of next
week.
