Area Forecast Discussion
National Weather Service Gaylord MI
408 PM EDT Sun Jul 29 2018

.NEAR TERM...(Through Tonight)
Issued at 347 PM EDT Sun Jul 29 2018

...Thunderstorms into the Evening...

Broad troughing remains across eastern Canada and down into the
Great Lakes with a core of -14C to -16C H5 temperatures sitting
across northern Michigan. SPC mesoanalysis reveals over 500 J/KG
MLCAPE and no CINH across eastern upper Michigan and a narrow
corridor from Manistee county up through Presque Isle county, pretty
much where agitated CU field and numerous small showers/storms have
developed over the last few hours.

As anticipated, weak winds aloft and a limited shear profile has
lead to short-lived "pulse" storms, with some hail up to nickel size
reported. DCAPE values in excess of 600 J/KG is supporting some
gustiness. A few updrafts have tried to push into brief severe
territory (mainly hail). But thus far, just the typical summertime
pop-and-drop storms.

Tonight: Ongoing showers and storms will obviously continue into the
early evening hours with further development eastward toward Lake
Huron. With loss of heating, convection will run it's course through
mid evening or so, giving way to quiet weather for the overnight
hours.

Severe weather threat: As mentioned, weak winds and limited shear
into the evening, not supportive of longer lived organized updrafts.
DCAPE values running 600 to 900 J/KG and sub 10K foot freezing
levels will continue to support a gusty wind and marginal severe
hail threat.

&&

.SHORT TERM...(Monday through Wednesday)
Issued at 347 PM EDT Sun Jul 29 2018

...Typical Northern Michigan Summer Weather...

High impact weather potential: Minimal. Perhaps some locally heavy
thunderstorms across portions of northern Michigan again Monday.

Pattern synopsis/forecast: Broad long-wave troughing expected to
remain across the Great Lakes through mid-week, with sharper
shortwave trough slowly working through it across the northern Ohio
Valley and southern Lakes. While the latter looks to focus the most
inclement weather off to our south, cool air aloft tied to broader
troughing will bring some additional shower and thunderstorm
concerns, especially Monday.

Primary forecast concerns/challenges: Addressing mostly low end
shower and thunderstorm chances through the period, with the
greatest focus on Monday.

Details: Another day of diurnally-driven showers and thunderstorms
expected Monday as cool air aloft and low level moisture both
linger. Early morning sunshine will once again give way to a
developing cu field through the morning hours, with these cu
developing enough organization and vertical depth to develop at
least a few showers during the afternoon. Target area for showers
looks to change a bit from the last few days, with diffuse pressure
fields supporting a bit more robust east flow off Lake Huron, likely
focusing "best" shower coverage across the interior highlands and
parts of northwest lower Michigan. Mean layer cape profiles of
several hundred joules/kg definitely supports some thunder
potential, with the strongest storms capable of producing some hail
and locally gusty winds (very similar to what has occurred this
afternoon).

Focus thereafter is more on that southern Great Lakes wave as it
slowly rotates northeast. Dprog/dt's of all guidance continues a
slow southern displacement to better dynamics, with much of the
deeper moisture and forcing occurring off to our south. Suppose some
deformation and deeper moisture may clip areas down near Saginaw Bay
by later Tuesday into Tuesday night. Otherwise, current trends
support much of the area and most of the time remaining dry Monday
night right through Wednesday.

&&

.LONG TERM...(Wednesday night through Sunday)
Issued at 347 PM EDT Sun Jul 29 2018

Guidance in reasonable agreement of next organized wave cutting
across the area later Wednesday night into Thursday, bringing at
least the threat for a bit more organized and widespread shower
activity along with it. Still cannot rule out a few more showers at
times through the rest of the period as waves pass overhead and
moisture lingers. Would like to stress again that per the usual with
summertime activity and all the attendant uncertainty, the forecast
will look much wetter than what will actually occur, with extended
periods of low pop shower mention. Very likely that most areas
experience little rain at all after Thursday. Temperatures will
gradually warm, with highs this weekend likely reaching well into
the 80s.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 228 PM EDT Sun Jul 29 2018

Daytime heating and cool air aloft has lead to the development of
scattered showers and thunderstorms across the region this
afternoon. APN will be impacted the most, with showers and storms
moving through or near that terminal site over the next few hours.
Otherwise, VFR weather will dominate today and tonight.

Additional showers and storms are possible on Monday.

&&

.MARINE...
Issued at 347 PM EDT Sun Jul 29 2018

Relative high pressure will continue to bring light winds
and lake breezes leading to no issues with winds and waves right
through the middle portion of this week, if not longer. Still
looking at a few showers and thunderstorms to end this afternoon and
again Monday to drift into portions of the Lake Huron nearshores, as
well as northern Lake Michigan. While no severe storms are expected,
any of the stronger storms will be capable of producing variable
gusty winds and some small hail.
