.DISCUSSION...
Issued at 252 PM EDT Fri Aug 16 2024

- Potential for Thunderstorms into Saturday

The mid level low in northern WI will slowly drop down into lower MI
on Saturday.  The deeper cyclonic flow associated with this feature
along with the cooling aloft will support a continued environment
favorable for shower formation. PWAT's remain elevated with
values up around 1.5 inches based off of the ensemble plots.
Ensemble qpf plots suggest most locations will be seeing some
rain during this period as most members are showing qpf. We also
maintain some instability through the period so a risk for
thunderstorms exists. The convection that has persisted this
morning along the lakeshore was weakening. Overall the forcing
remains weak this afternoon but decent surface based CAPE is
expected with inland values up over 1000 J/kg. There will also be
weak low level convergence inland. Based on this, any renewed
convection this afternoon should be further inland with the
coverage forecast to be isolated/scattered. Early this evening a
stronger mid level vort max moves in and the lift associated with
this feature is expected to lead to a an area of storms tracking
eastward into the CWA. As for the severe thunderstorm risk, the
core of stronger mid levels winds stays south and west of the CWA
which will limit the deep layer shear and degree of storm
organization. As for Saturday, much less instability is forecast.
However with the cold temperatures aloft and deep cyclonic flow,
any heating will generate showers and a few storms. We will
maintain the risk for storms in the forecast into Saturday.

- Mostly dry and cool next week

A few lingering showers on Sunday will exit the area as the upper
low in our neck of the woods finally moves off to the east. In it's
wake, Lower Michigan will spend the bulk of the upcoming week under
the influence of northwest flow, thanks to an upper level ridge that
reasserts itself over the plains. What this means for us is a cooler-
than-normal airmass (highs pleasantly in the 70s), low humidity,
plenty of sunshine, and relatively light winds. Overall, a very
tranquil week appears to be on track for us.

There are some indications that a shortwave comes over the ridge
sometime in the 2nd half of the week and could produce a few showers
for us, but this is far from certain, and regardless is not likely
to "ruin" any days. Of note, overnight temperatures especially early
in the week are likely to be fairly chilly and will be dropping down
into the 40s - especially in rural/northern areas.

&&

.AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...
Issued at 139 PM EDT Fri Aug 16 2024

Widespread MVFR and occasional IFR ceilings and visibilities from
earlier are slowly improving, with some sunshine trying to spread
into the area from the southwest. While conditions should spend
most of the afternoon VFR at most locations, showers and scattered
thunderstorms are expected to begin redeveloping by mid afternoon,
primarily affecting northern and eastern areas. A more widespread
line of storms is likely this evening - generally between 6pm and
10 pm - to move in from Lake Michigan and sweep across Lower
Michigan. Behind this line of storms, winds shift a bit to come
from a due west direction and thunderstorms taper off to hit-or-
miss showers. This showery pattern, with steadily worsening MVFR
or even IFR ceilings and visibilities overnight and continuing
throughout much of the day Saturday with only very limited
improvement expected.

&&

.MARINE...
Issued at 252 PM EDT Fri Aug 16 2024

The winds and waves have decreased this afternoon as expected but
they will increase again on Saturday, especially later in the day.
We will likely see at least a moderate swim risk for parts of the
area later in the day as waves start topping 3 feet. We will hold
off on issuing a headline for that risk at this point given the
marginal setup.
