.SHORT TERM /THROUGH TONIGHT/...
Issued at 310 AM EDT Wed Aug 20 2025

High pressure will gradually build into the Great Lakes today.
Lingering cloud cover is expected to start the day and may take
until late morning to scatter out. Sunshine should become more
dominant into the afternoon, though some patchy cloud cover may
hang on a bit longer in spots. Afternoon highs look to reach the
70s (cloud cover dependent), with light winds and overall quiet
sensible weather.

By tonight, the surface high will become more firmly
established overhead. Skies will trend mostly clear, and winds
will become calm. This will allow for efficient radiational
cooling, with overnight lows dipping into 50s, to even upper
40s for some locations. The combination of lingering surface
moisture, clear skies, and calm winds will likely support the
development of patchy fog tonight into Thursday morning,
especially areas that received recent rainfall. Any fog
development is expected to burn off quickly as the sun rises.

.LONG TERM /THURSDAY THROUGH TUESDAY/...
Issued at 310 AM EDT Wed Aug 20 2025

High pressure settles in place across the Great Lakes mid-week,
bringing a stretch of quiet weather and moderating
temperatures. Mornings may feature patchy fog that burns off
quickly, leaving plenty of sunshine. A warming trend develops
into Thursday and Friday, with highs well into the 70s to mid
80s by Friday. Overnight lows will be cool Wednesday and
Thursday nights, dipping into the 50s, to even possibly the 40s,
under clear skies and light winds.

Changes arrive later Friday into Saturday as an upper-level
trough digs across the region. A cold front will likely slip
through sometime during this period, though moisture looks
limited. Light showers will be possible along/ ahead of the
front, with perhaps a few embedded thunderstorms. Behind the
front, notably cooler air spills into the region Sunday, with
highs likely stuck in the 60s to low 70s and overnight lows
falling into the upper 40s and low 50s along with occasional
chances for lake induced showers through early next week.

Issued at 1212 AM EDT Wed Aug 20 2025

Cloud cover and associated lowered CIGs will linger across parts of
northern Michigan tonight, improving around and shortly after
sunrise this morning. Patchy FG/BR development will be possible
where breaks in the clouds materialize overnight -- most likely CIU
and PLN at this time. North-northeast winds between 5-10 kts are
anticipated across the area today with VFR conditions expected for
all TAF sites by mid to late morning.
