.DISCUSSION...(This evening through next Sunday)
Issued at 300 PM EDT Sun Sep 25 2022
-- Strong storms possible mid-late evening tonight --
We continue to monitor the potential for some strong to locally
severe storms that could affect the area west of U.S-131 mid to late
evening tonight. SPC has pulled the Marginal risk of severe weather
to the U.S.-131 corridor for this evening, as was indicated they may
do that after coordination this morning.
We have showers that have been affecting the area for the last few
hours starting to wind down at the lakeshore and moving east out of
the area. These showers were associated with a well defined short
wave that is starting to push east of the area per WV imagery. The
visible satellite imagery shows some breaks developing in the clouds
in the wake of the first wave.
We are expecting to see another increase of showers by mid evening,
with potentially a line of storms moving in toward and just after
00z this evening. This line of storms will be driven by the more
potent short wave that is pushing into Central Wisconsin this
afternoon. The models and ensemble means are in fairly good
agreement showing a few hundred J/kg of CAPE over the lake ahead of
this wave. Then as the wave moves over the lake, it jumps to around
1,200 J/kg of MU/SB CAPE. Forecast soundings shows this instability
well.
These types of events tend to overperform given the strong heat and
moisture flux off of the mid 60s F lake water interacting with the
colder air aloft. The HRRR and HREF members are showing good
potential of gusty winds, which makes sense given the setup. Deep
layer shear is only around 30 knots, which could be better. The
storm outflow, and unstable conditions over the lake will help to
compensate for the ok shear. Mid level lapse rates around 7.0 C/km
will also help with some hail generation.
The thunder threat should drop a bit after this wave moves through
later this evening. We can not rule out an isolated storm along the
immediate lakeshore tonight and Monday with the upper low/trough and
associated cold pool firmly entrenched over the area.
-- Unsettled weather to persist through Tuesday and end Wednesday --
This cool, damp, and unsettled weather pattern will linger into at
least Tuesday for all of the area, before shifting more toward the
lakeshore for Wednesday, and then ending after that.
The cyclonic flow and cold pool aloft with the upper low in place
and jet stream to our south will help to ensure some showers will
persist. We will continue to see tough to time short waves move
through in the general NW flow. The showers will eventually be more
driven by lake effect processes as delta t's will be around 20C with
inversion heights at least 9-10k ft high if not higher. NW flow
favored areas will see much of the shower activity.
Tuesday night and early Wednesday, the cyclonic flow will persist.
However, the orientation of the flow with ridging trying to build in
will turn the flow to NNE and push lake effect rain showers offshore
except near Little and Big Sable Points. We will see ridging build
in by Thursday, and bring seasonable temperatures and dry weather
for Thursday and Friday.
-- Some rain next weekend from "Ian"? --
We are watching the medium to longer range for next weekend for the
possibility of some rain making it to Michigan from "Ian". There
remains a lot of uncertainty with this. If Ian can miss the upper
trough moving out, it may meander a bit more west around the Bermuda
High and possibly bring some rain on its NW flank. If it were to
move further east, we would likely miss it, and stay dry and mild
with ridging overhead while it moves out of the way.

.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 655 PM EDT Sun Sep 25 2022
Gusty showers and thunderstorms will be on the increase for the
TAF sites in Southwest Lower MI to start the period. Radar trends
show the storms to the west of KAZO extending into eastern WI. The
strongest activity should occur prior to 04z here in Southwest
Lower MI. IFR and lower conditions look likely and wind gusts
could top 35 knots as the showers and thunderstorms roll through.
Widespread MVFR conditions should settle in overnight and continue
into Monday. There is a potential for the cloud bases to lift to
VFR in the afternoon but confidence on that happening were not
high enough to reflect the trend. Any stronger shower could
temporarily lower the conditions to IFR through the period.

.MARINE...
Issued at 300 PM EDT Sun Sep 25 2022
We believe we have the upcoming wind/wave event handled well at this
point with the upgrade to the Gale Warning earlier. The Small Craft
Advisory in effect until 8 pm tonight looks good with winds
frequently gusting to around 20 knots or so, and waves at the buoys
and on webcams around 3-4 ft.
We expect that a line of storms will come through this evening,
mainly south of Grand Haven. These storms have a good potential for
producing winds of 40-50 knots. Then behind the storms, the winds
will stay up around 30-35 knots in the colder air filtering in
behind the line. There looks to be two or three surges of gales
after the storms this evening, through tomorrow evening.
We continue to advertise the potential of some waterspouts this
afternoon and evening with the colder air coming in over Lake
Michigan. The waterspout potential will likely go down a bit as the
stronger winds make the conditions a little more hostile for the
formation of waterspouts.
It looks like headlines are likely to persist through Tuesday night
before winds and waves will come down enough.
