.KEY MESSAGES...

- A calm and pleasant Labor Day weekend is in store!

&&

.SHORT TERM /THROUGH TONIGHT/...
Issued at 310 AM EDT Fri Aug 29 2025

With mostly clear skies being realized across the area early this
morning and with fog not really being seen, temperatures have
already dropped into the mid 30s across the interior west and in
some isolated spots of the interior east and central. Thus, with
observations showing mostly calm winds across the area early this
morning, expect frost to develop over the interior west and for
patches of frost to develop over isolated spots in the interior
central and east too. Thus, the Frost Advisory over the interior
west this morning will continue until 9 AM EDT.

Once we see daylight today, expect the temperatures to rise up into
the 60s as mostly sunny skies continue via high pressure ridging.
With light winds dominating due to the ridging, the day should be
quite pleasant! Moving into tonight, we could see an isolated spot
or two develop patchy frost in the interior east (and to a lesser
extent interior west). However, with temperatures projected to be a
few degrees warmer than this morning, no widespread or areas of
frost are expected; thus, no Frost Advisory will be issued at this
time as temperatures in the interior are only expected to dip into
the upper 30s. In addition, while we may see some patchy fog develop
over the interior areas tonight, confidence in this occurring is low
as we really haven`t seen any fog develop across the U.P. early this
morning, and no rainfall is expected for the next several days.

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Issued at 254 PM EDT Thu Aug 28 2025

A warming trend kicks off into the weekend with temperatures turning
more seasonal. Meanwhile, dry weather persists with ridging over the
Great Lakes at least into early next week. Chances for rain finally
return sometime in the Tuesday-Wednesday timeframe as a trough drops
out of Manitoba/Ontario with an associated cold front, though
guidance is in some disagreement on timing. A midlevel low closes
off and deepens over the Great Lakes by early Thursday. Anomalous
troughing lingers somewhere over the Great Lakes through late next
week, keeping PoPs going through the end of the forecast period
while temperatures turn cooler than average again behind the midweek
cold front.

.AVIATION /06Z TAFS THROUGH 06Z SATURDAY/...
Issued at 105 AM EDT Fri Aug 29 2025

VFR conditions prevail overnight save for patchy fog that may
temporarily bring IFR or lower vis at IWD. So far tonight they`ve
already managed to bounce between VFR and LIFR a few times.
Confidence is less at CMX and SAW thus have opted to leave any
category changes in the TAF. Otherwise, any fog that does develop
will burn of come sunrise. VFR conditions and light winds prevail
under high pressure through the rest of the day (and rest of the
weekend for that matter)! Yay!

.MARINE...
Issued at 310 AM EDT Fri Aug 29 2025

With high pressure over the Great Lakes through the weekend and at
least into early next week, expect winds to remain light at 20 knots
or less before deepening low pressure heads towards the area by the
middle of next week.
