.DISCUSSION...(Today through next Tuesday)
Issued at 330 AM EDT Wed Sep 2 2020

-- Showers end this morning then clearing by noon--

A jet educed frontal wave moving through this area early to mid
morning is bringing and area of showers, some heavy north of a
Muskegon to Mount Pleasant line. There is only marginal
instabilitywith the greatest instability over Lake Michigan. A
40 knot low level jet tracking east northeast, north of Muskegon
by 5 am will be east of Lake Huron by 10 am this morning. So, the
the axis of the low level jet north of I-96, that is where most of
the rain will be between now and say 8 am. Rainfall amounts west
of US-131, and north of Big Rapids may approach an inch is
isolated locations before it comes to an end.

Areas near I-96 and maybe as far south as I-94 likely will see a
period of showers during the mid morning. These showers will move
to toward I-69 by mid to late morning.

Behind the area of showers is a sharp clearing so all areas should
have mostly sunny skies by early to mid afternoon. Since there is
not really any significantly cooler air behind this front, highs
should be in the mid to upper 70s in most locations.

High pressure moving over the area tonight means clear skies and
light winds, through the winds may ramp up toward morning as the
next system will begin to impact our area before sunrise.

-- Cold front brings windy conditions Thursday and cooler
 Friday--

The next system is very strong surface low (upper wave goes
negative tilt) and tracks a 980 mb surface low east northeast near
50N. That is so far north that we do not get much mid level
moisture with this frontal system, so rain seems rather unlikely.
On the other hand, we sure do get the wind with this frontal
passage. At this point is does not look like advisory criteria
winds inland but I could see gusts to near 35 mph. It will be warm
too, highs should be near 80. The cooler air moves in Thursday
night and remains in place Friday. Highs will struggle to make 70
on Friday.

-- A storm system brings showers and thunderstorms by Sunday--

The next upstream system looks more impressive than the Thursday
system and should move into the area by Sunday. The surge of warm
air ahead of the system should bring showers and thunderstorms to
the area by Sunday

--Cooler weather expected by early next week--

The colder air follows by Monday but there is some question as to
what happens to the trailing shortwave, does it close off an upper
low over the western states or dig a very deep eastern trough? If
the GFS version of this happens it will be a very wet and chilly
week.

&&

.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
Issued at 140 AM EDT Wed Sep 2 2020

A band of showers with MVFR/IFR cigs is approaching our TAF sites
from the west at I write this. The front will come through the
area just after sunrise, but prior to that there should be 3 to 4
hour period of MVFR/IFR cigs at all of our TAF sites. The area of
shower, which is currently nearly a solid area of showers from
easter Upper Michigan, across eastern Wisconsin into central
Illinois is expected to weaken considerably by the time it crosses
our TAF sites around 12z (more or less). I put the showers in the
MKG and GRR TAF sites only as I do not think the showers will last
long enough to impact the other TAF sites.

Once the front comes through skies will clear, winds will turn
northwest and become gusty. Skies should remain clear Wednesday
night but winds will diminish to under 10 knots by sunset.

&&

.MARINE...
Issued at 347 AM EDT Wed Sep 2 2020

We earlier through the frontal wave would briefly increase winds
to 20 to 30 knots north of Muskegon between 2 am and 6 am but that
does not appear to be the case so I have expunged the headline.

Winds behind the weak cold front today will increase to 10 to 20
knots from the west to northwest. That will result in 2 to 4 foot
waves.

High pressure will move across the near shore this evening
decreasing winds but as the high moves to the east of Michigan
later at night wind will turn to the south and increase to 15 to
25 knots toward morning.

A fairly impressive storm system (982 mb low) will track east
near 50N on Thursday. That results in a very strong pressure
gradient with the 1020 mb high over Kansas, so winds will increase
to 20 to 30 knots from the south and southwest during the day
Thursday, we may need gale warnings over northern sections. The
cold front comes through by midday Thursday, which turns winds to
the west then northwest. Our storm deepens to below 980 mb
(ECMWF). This should keep strong winds going into the Thursday
night. We will have to look at that more closely on the day shift
for possible headlines.
