The Frost Advisory continues later tonight into early Thursday

frost to develop. Patchy frost is possible elsewhere away from
Lake Michigan during this period, with lows in the upper 30s.

Sheboygan and Ozaukee Counties overnight, as any drops lower
than currently forecast may allow for areas of frost to develop

.SHORT TERM...
Issued 302 AM CDT Wed Oct 8 2025

Tonight through Friday

High pressure centered over Wisconsin this afternoon will shift
eastward tonight into Friday. Mostly clear skies and light winds
tonight will allow temps to fall into the 30s most places away
from Lake Michigan. The coldest conditons are expected roughly
northwest of Highway 151, with a Frost Advisory in effect again
tonight.

Southerly winds will develop tomorrow as the high shifts
eastward ahead of an approaching low. The high will maintain a
strong enough influence to keep mostly clear skies and dry
weather going through the day. Temperatures are expected to
return to right around normal for afternoon highs.

There will be a chance for showers Thursday night into at least
early Friday as low pressure passing by to the north drags a
cold front through the area. Kept precip chances on the lower
end (20-30%) for now, given a fair amount of dry air in the
lowest 5 kft and also above about 10 kft. A few showers may
linger into Friday night as the low drops southward just east of
the forecast area. Highs Friday will likely be a couple degrees
warmer than Thursday under southwest winds, though there is
some uncertainty in these temps, which will be impacted by the
timing of the front along with cloud cover and shower chances.

High pressure will slowly move to the east of the area overnight
into Thursday night. Light to calm winds are expected overnight

.MARINE...
Issued 936 PM CDT Wed Oct 8 2025

High pressure around 30.5 inches over the eastern Upper
Peninsula of Michigan will shift eastward overnight into
Thursday, becoming centered over New York by Thursday evening.
East winds overnight will veer south to southeast by late
Thursday morning, as the high shifts eastward.

Southwest winds will then increase Thursday night into Friday,
ahead of an approaching low around 29.8 inches and an associated
cold front. Wind gusts up to 30 knots will be possible through
this period. The forecast gusts may need to be raised upwards to
reflect this possibility. In addition, the winds may bring a
Small Craft Advisory possibility for the nearshore waters for
Friday.

North to northeast winds will return Saturday, as the low moves
into southern Michigan.
