.DISCUSSION...
Issued at 315 AM EDT Sun Jul 20 2025

- Quiet weather through Tuesday

Cold front moving through Michigan this morning will exit the
state by late this morning. Patchy fog to hang on through much of
the morning with low clouds slowly eroding through the afternoon.
High pressure brings dry weather today into at least Tuesday with
comfortable high temperatures in the upper 70s to lower 80s.

- Heat and Humidity returns midweek

Warming trend early this week will continue into midweek. Wednesday
and Thursday should see high temperatures get back into the lower
to mid 90s for most if not all of the area. Starting to look
likely we will see some 100 plus apparent temperatures both
Wednesday and Thursday and potentially Friday into the weekend as
well. Heat sticks around into early next week, though we could
fall off into the mid to upper 80s over the weekend for a tiny bit
of relief. Expected air mass will bring some chance for
afternoon/evening thunderstorms that could limit temperatures a
little. Best chance for this is starting to look like Thursday and
Friday versus earlier in the week.

.AVIATION /12Z TAFS THROUGH 12Z MONDAY/...
Issued at 721 AM EDT Sun Jul 20 2025

Fog and low clouds with a touch of drizzle on occasion to continue
this morning. IFR and LIFR conditions continue to be common for
the first few hours of the taf period before gradual improvement
occurs in conditions.

.MARINE...
Issued at 315 AM EDT Sun Jul 20 2025

Advancing high pressure could bring some increase winds and waves
to Lake Michigan...especially the northern zones where moderate
swim risk is likely later today. Could be a sneaky high risk swim
afternoon/evening if winds are a little stronger than currently
expected when they shift to the northwest later today.
