OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
214 PM CST Mon Jan 5 2026

FOR WATERS BEYOND FIVE NAUTICAL MILES OF SHORE ON Lake Michigan.

Waves are provided as a range of significant wave heights, which
is the average of the highest 1/3 of the wave, along with the
average height of the highest 10% of the waves which will
occasionally be encountered.

.SYNOPSIS...

29.6 inch low pressure will form over northern Missouri this
evening, resulting in increasing east-southeast winds over
southern Lake Michigan with weaker east-northeast winds north. The
low will cross the southern third of the lake near daybreak
Tuesday, moving into Lower Michigan by the afternoon hours. Winds
will shift out of the northwest behind the departing low Tuesday
afternoon and evening. Gales are not anticipated during the low`s
passage. Rain is expected across the open waters tonight through
Tuesday, with some rain-snow mix possible over far northern Lake
Michigan. Some fog is possible tonight, though dense fog is not
anticipated at this time. Trends will be monitored through this
evening.

30.1 inch high pressure will build over the Ohio River Valley on
Wednesday, bringing a southwest wind shift across the waters.
South-southwest winds will continue through the day on Thursday
as 29.6 inch low pressure moves from the northern Great Plains
into the Mississippi River Valley. Low pressure of at least 29.6
inches will cross southern Lake Michigan on Friday, progressing
east into Quebec through Saturday night. The low`s approach and
passage will bring increasing northerly winds Thursday night into
Friday evening, with winds shifting out of the west-northwest
Saturday through Saturday night behind the departing low.
Depending on the low`s central pressure, periods of gales may be
possible Saturday and Saturday night. Forecast guidance remains
uncertain regarding said central pressure, so trends will be
closely monitored through this week. Periods of rain and snow are
expected Friday through Sunday.
