Area Forecast Discussion
National Weather Service Marquette MI
211 PM EDT Tue Aug 27 2019
.UPDATE...
Issued at 732 AM EDT TUE AUG 27 2019
Last few HRRR and ESRL HRRR runs have shown the most robust
showers/storms in the south central this afternoon, so have
increased POPs there to likely to match the higher POPs out west.
Still think small hail and brief gusty winds would be the main
concerns with stronger storms.
&&
.SHORT TERM...(Today and tonight)
Issued at 425 AM EDT TUE AUG 27 2019
The cold front has cleared early this morning all but the far
eastern U.P., but the fun is just beginning. WV satellite this
morning shows drier air pushing in aloft behind the front and MSAS
analysis lines up with an approximately 1000 mb trough over eastern
Lake Superior. As rain associated with this system continues to move
out over the next few hours, attention will turn to the CAA aloft
today and its two ramifications: gusty winds both on land and water,
and instability showers and storms this afternoon.
Hedged high on winds and gusts today. Given the fact that we will
see at least some pockets of sunshine today while pressures rise
behind the trough, the mixing down of isallobaric driven gusts
should lead to gusts around 30 mph for most of the day - perhaps a
little less over the east and a little stronger over the Keweenaw.
These winds and gusts persist right through the night with most
models keeping the lowest 1 km or so mixed and the NAM showing the
strongest 925-850 mb height rises and CAA approximately 03z-09z Wed.
This also means that the statistically driven models and blends
(MOS, NBM, etc.) are all too cool tonight, especially over the west.
Therefore, hedged towards the raw model consensus for lows tonight,
which should stay above 50 for almost everyone despite the much
cooler air aloft.
As teased above, the other main story today will be the development
of afternoon instability showers and thunderstorms with steep low-
level lapse rates, with extra forcing provided by a vort lobe
rotating around the main closed upper low about 18-21z. NAM and GFS
both ticked CAPE up slightly from yesterday, now both resolving some
pockets of 1000-1500 J/kg CAPE - impressive given storm tops of only
7-8 km. CAMS are also actually quite bullish with thunderstorm
development after 18z over the west, spreading across the central
U.P. around 21z and then exiting east by sunset. This type of low-
top storm environment with low freezing levels and mixed out low
levels can sneak up on us, so don't be surprised if some storms
produce hail (though mostly small) and occasional 40+ mph gusts this
afternoon.
By tonight, we'll again shift gears - this time away from thunder
and into lake-effect (rain) mode. A secondary push of cold air aloft
(models generally agree on 850 mb temps getting as cool as 2-3 C for
a few hours) generates enough lake-based instability for a broken
convergence band of showers to focus into the western shore of
the Keweenaw late tonight and into Wednesday morning. Not
expecting anything too significant out of it except for perhaps
0.1-0.2" of additional rainfall for those areas, and a reminder
that winter is not too far off.
.LONG TERM...(Wednesday through Monday)
Issued at 504 AM EDT TUE AUG 27 2019
Models suggest that mid/upper level troughing through the northern
Great Lakes will give way to a more zonal pattern this weekend as
deep mid/upper level low lifts northward from northern Ontario
through Hudson Bay. Below normal temps Wednesday will recover with
readings near or slightly below average into this weekend.
Wednesday, cyclonic westerly low level flow with deep moisture over
the area and 850 mb temps to around 3C (lake temps around 17C-18C)
will support lake effect/enhanced rain showers into the the west and
portions of north central Upper Michigan during the morning as a
shrtwv moves through. Showers should taper off during the afternoon
as low and mid level drying takeover. Windy conditions will also
prevail with mixing through 4k ft supporting peak gusts to near 35
knots at KCMX and to near 30 knots over much of the rest of Upper
Michigan.
Thursday, as a shortwave trough and cold front moves through the
area, moderate to strong 700-300 qvector conv should be able to
support sct shra even with limited moisture inflow. A few TS will
also be possible by afternoon with forecast MLCAPE values to
around 500 J/Kg. WAA ahead of the front will help boost temps into
the low to mid 70s.
Fri-Sat, sfc high pressure and dry air will build into the northern
Great Lakes behind the front with pleasant conditions. Highs in the
upper 60s and lower 70s with breezy conditions Friday giving way to
light winds with lake breezes on Saturday. Lows may drop into the
upper 30s to lower 40s inland with readings closer to 50 along the
Great Lakes.
Sun-Mon, although Sun is also likely to remain dry with any stronger
shrtwvs remaining to the north through northern Ontario, there is
more uncertainty by Monday with model differences in handling the
WAA pattern. Some rain may return to the area depending on the
position of the developing warm front.
&&
.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 211 PM EDT TUE AUG 27 2019
A cluster of thunderstorm have developed near KIWD this afternoon,
and will continue to push east towards at last KSAW later this
afternoon and evening. Confidence wasn't high enough to include
prevailing mentions at KCMX, so for now just have VCTS for later
today. These thunderstorms will be capable of producing small hail
and gusty winds, stronger then the gusty prevailing southwesterly
winds expected today. Additional showers and thunderstorms will be
possible behind this first round later this evening at KIWD, and
potentially into the overnight hours at KSAW. MVFR ceilings will
overspread the TAF sites from the west tonight into Wednesday
morning, with lake-effect rain showers at KCMX. Winds will become
westerly overnight, with lingering elevated wind speeds.
&&
.MARINE...(For the 4 AM Lake Superior forecast issuance)
Issued at 425 AM EDT TUE AUG 27 2019
Cold front has cleared most of the lake early this morning and will
move entirely off the lake by mid-morning. Low pressure gradually
deepening and heading towards the Hudson Bay today through early
Thursday will keep a strong pressure gradient over Lake Superior,
and thus back to back days of strong WSW winds. Expect WSW winds of
25-30 kts west and 20-25 kts east today to increase to marginal
gales tonight on the western arm (where there is a Gale Watch in
effect) and 25-30 kts east. Winds become W and subside slightly
midday Wed west but increase east so that the whole lake sees about
30 kts of wind. Low pressure system finally moves away Thursday and
winds subside to around 20 kts across the lake. Next cold front, this
one weaker, pushes across the eastern arm Friday with some 25 kt
gusts. High pressure builds in Friday through the weekend and winds
subside to below 15 kts for that period.
