Area Forecast Discussion
National Weather Service Gaylord MI
1010 PM EDT Wed Jul 10 2019

.UPDATE...
Issued at 1010 PM EDT Wed Jul 10 2019

Low pressure center has reached Eastern Lake Superior late this
evening...with the associated cold front extending southward
along the Michigan shoreline of Lake Michigan. Area of strong
convection continues to fire along and ahead of this system across
the northern half of our CWA with a narrow axis of strong
instability...good low level moisture and modest shear. The front
will continue eastward progress thru our CWA over the next few
hours...and should push east into Lake Huron by 06Z. Remaining
convection will also push east with this feature and should show a
general diminish in intensity as we head into the overnight hours
and lose any remaining daytime instability enhancement.

&&

.NEAR TERM...(Through Tonight)
Issued at 334 PM EDT Wed Jul 10 2019

...Strong/severe storms possible thru 1 am...

High Impact Weather Potential: Severe storms possible thru this
evening, with wind/hail primary threats and a tornado possible.

Low pressure is north of Lake Superior. An initial cold front is
moving across western upper MI and central WI, while a secondary
front trails off across northern MN. Warm and muggy air is in
place ahead of the front; MlCape values are 1-1.5k J/kg over the
interior of northern lower MI, and 500-1k over eastern upper. Dew
points have been dropping since early afternoon, albeit only
slowly (not as many 70+f readings as earlier). Scattered
showers/t-storms have formed over ne lower MI, as well as
upstream over central upper MI and se Lake Superior.

Will be watching for spikes in activity late this afternoon in ne
lower MI. As mentioned earlier in the day, the better/deeper shear
is not here yet, but an instability gradient and backed surface
winds are parked (as usual) along the ne lower MI coastline. We'll
have to see if anything can take advantage of the better 0-3km
helicity that is present there (while not getting overwhelmed by the
decreasing instability as one heads further east).

That's not the main show. The main show (presuming we have one) will
be with the incoming cold front, along with an associated digging
shortwave and height falls crossing northern Lake MI. Anticipate
the cap eroding and eventually breaking in a more serious manner
over central upper MI over the next couple of hours. This activity
will lift ene-ward, primarily across Superior, initially. As
height falls migrate eastward, additional deep convection should
fire further east in upper MI and over northern Lake MI, perhaps
as soon as 6 pm but more likely towards 8 pm. Storms will have a
short window to congeal into a small MCS as they cross northern
MI, mainly between 8 pm and 1 am. Tendency for storms to organize
(0-6km bulk shear increasing to 40-50kt) will be countered by
decreasing instability as we approach and go past sunset. Pops and
severe threat both look to be highest north of M-72, where height
falls/forcing will be most prevalent.

Straight line winds are the primary threat, especially as any small-
scale bows and other curvilinear features emerge. Severe hail is
also possible, particularly early in the event while cells are more
discrete and instability is maximized. A stray tornado is not
terribly likely, but is not ruled out. Local boundaries (including
outflow boundaries, and the ne lower MI lake breeze convergence
zone) will be key in any tornado development.

A sharp airmass change will take place by morning in eastern upper
and nw lower MI, as cooler/drier air arrives. As is typical, the
initial dislodgement of warm/moist overlake air will shove some
status or stratocu ashore into western and northern portions of
the forecast area. A few sprinkles or even some drizzle could
develop overnight. Temps will lower into the mid 50s to near 60f
in eastern upper, near 60f in nw lower, but only into the mid 60s
in ne lower.

&&

.SHORT TERM...(Thursday through Saturday)
Issued at 334 PM EDT Wed Jul 10 2019

High Impact Weather Potential: Thunderstorms possible
Friday evening/night...mainly over northwest lower.

Primary Forecast Concerns/Challenges: Rain and thunder chances.

Pattern Synopsis/Forecast... A cold front associated with a low
pressure system to the east of Hudson Bay and attendant long wave
trough...along with ample moisture will continue rain showers
through the morning/early afternoon hours, mostly over northeast
lower. Surface high pressure will build into the Great Lakes region
from the central Great Plains and said upper level trough will exit
the forecast by Thursday afternoon. Aforementioned high pressure
will produce precipitation free weather and mostly sunny skies
Thursday evening through Friday. Temperatures will be much cooler
Thursday behind the cold front...possibly some locations not even
reaching 70. The warmest locations will be near Saginaw Bay as that
area will be the last area said cold front sweeps through. The next
chance for precipitation will be late Friday evening/night as
another cold front associated with a Canadian low pressure system
sweeps through the area and lasts through most of
Saturday...although this will not be a washout at all, only hit and
miss rain showers and possibly some rumbles of thunder. Highs will
warm back into the upper 70s to low 80s Friday and Saturday.

.LONG TERM...(Saturday night through Wednesday)
Issued at 334 PM EDT Wed Jul 10 2019

Long range models differ during this period with high pressure
mentioned in the previous forecast period hanging around longer over
the Great Lakes region than the other. However, there are
indications of weak cold fronts and upper level waves with moisture
that may produce periodic chances of showers and thunder beginning
the next work week. Hot weather appears to return as well, with
daytime temperatures reaching into the mid to upper 80s by Monday.

&&

.AVIATION...(For the 00Z TAFS through 00Z Thursday evening)
Issued at 703 PM EDT Wed Jul 10 2019

A potent cold front will sweep thru Northern Michigan tonight...
producing showers and thunderstorms across much of our area. The
best chance for precip will be along and north of M-72. Isold
severe storms are also possible. Conditions will temporarily
deteriorate to MVFR and possible IFR within any storms that do
develop...with strong gusty winds within any storms as well.
Precip chances should end by around 06Z...but MVFR cigs are
expected overnight as ample low level moisture moves into the
region in the wake of the cold front. S/SW winds at around 10 kts
this evening ahead of the front will become NW overnight and
strengthen to 10 to 20 kts on Thursday with some higher gust
possible.

&&

.MARINE...
Issued at 334 PM EDT Wed Jul 10 2019

Southerly winds are a little gusty this afternoon, especially
near Gd Trav Bay, in advance of a cold front pushing across WI.
Showers/t-storms should develop as the front moves in, and some
could be severe this afternoon/evening, with gusty winds and hail.
Winds will become nw behind the front late tonight into Thursday,
and will be gusty at times, especially on Thursday morning on
Lake MI. There is some potential for advisory-level gusts and
waves.
