Area Forecast Discussion
National Weather Service Marquette MI
713 AM EDT Thu Apr 14 2022
.SHORT TERM...(Today and tonight)
Issued at 351 AM EDT THU APR 14 2022
Cooler air continues to work from west to east across the UP this
morning, as precipitation is changing over from rain to snow. The
snow isn't expected to last too long this morning, and has already
ended across the far west. A slushy light accumulation will be
possible with this snow and Houghton webcams do show around an inch
or so of slushy accumulations. The snow and precip should come to an
end through the rest of the morning hours with some clearing skies
as our resident low pressure system's dry slot lifts north across
the UP.
Sunny skies won't persist too long today as cyclonic flow around the
low pressure system will bring a cold front from west to east across
the area with developing stratocu. This cold front will bring steep
low-level lapse rates, allowing for a well-mixed boundary layer,
resulting in gusty SW winds across much of Upper Michigan. Any
sunshine this morning will only add to the low-level instability,
which could bring stronger gusts than currently in the forecast. The
strongest winds are expected across the Keweenaw and along the
downslope areas along Lake Superior with gusts around 35 mph the
norm, with some gusts approaching 45 mph this evening. Additionally
expect some iso to sct shsn this afternoon across the west half of
the UP, partially aided by Lake Superior instability. These showers
combined with the gusty winds could bring brief visibility
reductions as well.
Tonight, a little more of the same is expected, with shsn bcmg more
numr across the west half of the UP and the Keweenaw. Lake Superior
will enhance this snow potential, with some slushy accums possible,
especially across the Keweenaw where 1 to 3 inches of snow is fcst.
Snow could become pure LES by late tonight with 850mb temps falling
to around -13C, but winds will be out of the WSW, which isn't as
conducive as a wind direction to impact the UP. Late tonight, winds
veer slightly more westerly, which could bring some added
convergence with a band impacting somewhere along the western UP
somewhere btwn Twin lakes and Calumet. Temps will fall to around 20
across the west half with mid to upper 20s east, but with the
blustery winds, wind chills will fall into the single digits across
the west half by Friday morning.
.LONG TERM...(Friday through Wednesday)
Issued at 505 AM EDT THU APR 14 2022
Medium range forecast models indicate an active pattern setting up
across the Upper Great Lakes through the extended fcst period.
Lingering impacts are expected Friday into Saturday from the storm
system currently bringing moderate to heavy rain to the Upper Great
Lakes. The impacts Fri-Sat will be mainly in the form of blustery
west winds, cold temperatures and scattered -shsn/LES as the storm
system lifts north through Ontario and then east into northern
Quebec. As the pattern deamplifies late this weekend into the early
to the middle part of next week and becomes more quasi-zonal a
series of systems will bring more oppportunies for pcpn. Looks like
below normal temperatures will continue to be the rule through the
period.
Friday into Saturday, the presence of a shortwave moving through the
area and CAA in a westerly flow lowering 850 mb temps to -14/-15C
could result in briefly moderate lake enhanced snow across the
Keweenaw on Fri morning. Once we lose the forcing/enhancement from
the shortwave as it passes east of the area, expect LES to become
lighter through the day on Friday. Looking at the mixed layer and
momentum transport off the KCMX BUFR soundings, it looks like there
could be a potential for west wind gusts to approach near 40 kts or
wind advisory criteria on Fri. With the storm system expected to
lift east from northern Ontario into northern Quebec late Fri night
into Saturday, expect winds to gradually come down a bit and veer
northwest. With the winds veering northwest and 850 mb temps still
around -14C, expect light LES to work a bit farther inland into the
northern zones later Fri night into Sat. Drying/subsidence from the
west late in the day as the sfc ridge begins to build into the area
should put an end to the light LES. Highs both Fri and Sat should
be mainly in the 30s with lows Fri night in the upper teens to mid
20s.
A broad Canadian sfc ridge building over the area should result in
dry and continued cool conditions Sat night into Sunday. Lows Sat
night will range from the mid teens to the mid 20s, coolest interior
west. Interior highs Sunday will be mainly in the lower to mid 40s
with cooler readings in the 30s expected near Lake Superior.
Model uncertainty still exists with the next low pressure system
approaching from the Northern Plains which most of the models have
tracking into Upper Great Lakes late Sun night into Monday bringing
widespread accumulating snow of at least a couple of inches to the
fcst area. Most of deterministic models and the GEFS mean suggest a
weaker low (around 1015 mb) tracking along the UP/WI border on
Monday. The 00Z GFS shows a slightly deeper low around 1010 mb
tracking across the northern UP on Monday while the 00Z UKMET
indicates a much weaker low of around 1020 mb tracking well south
through southern WI/northern IL. Both these solutions appear to
represent respective northern/stronger and southern/weaker outliers
with regard to the low strength and track. Will stick closer to the
model blend solution for now on the fcst details. With both the
ECMWF and Canadian models advecting mixing ratios up to 2 g/kg into
the area with around a 6-9 hr window of isentropic ascent on the 280-
285K layer theta sfcs would expect snow amounts with the system
somewhere in the 1-2 inch range with maybe isolated higher amounts.
The active weather pattern will continue into at least the middle of
next week as deterministic models and ensembles indicate another
system could bring in another round of mixed pcpn into the fcst area
Wednesday into early Thursday.

.AVIATION...(For the 12Z TAFS through 12Z Friday morning)
Issued at 712 AM EDT THU APR 14 2022
Upper Michigan is within the dry slot of an occluded low pressure
system currently draped across northern Minnesota and northern Lake
Superior. With this low in the vicinity gusty west to southwest
winds will continue at all terminals through this period. As the low
lifts north today, clouds will begin to work back in from west to
east bringing a high-end MVFR stratocu deck across IWD/CMX. With
some daytime heating, this deck could lift into VFR. Scattered -shsn
are expected at IWD and CMX through most of the TAF period and could
bring IFR vsbys tonight. VFR conditions are expected through most of
the TAF period at SAW, but may fall down into high-end MVFR tonight
with isolated -shsn possible at times.

.MARINE...(For the 4 AM Lake Superior forecast issuance)
Issued at 452 AM EDT THU APR 14 2022
Southwest gales of 40 to 45 knots across the western half of the
lake this morning are expected to relax this afternoon, briefly into
the 20 to 30 knot range. Then tonight, winds will increase again
from the west to southwest with gales of 40 to 45 knots expected
across the western half of Lake Superior. By Friday, gales of 35 to
40 knots will be across the entire lake as a sfc low pulls away to
the north towards Hudson Bay. A ridge of high pressure will begin to
work in from the west on Friday night with a gradual decrease in
winds into the low 20 knot range by Saturday morning. As the high
pressure system expands across the lake on Sunday, winds will
decrease into the 10 to 15 knot range.
