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...

a high pressure ridge averaging 30.0 inches continues eastward
from the ohio river valley and eastern great lakes this evening,
allowing a light south breeze to overspread lake michigan,
strengthening (gusts to 20 kt) on thursday as the ridge builds to
30.2 inches and a trough of low pressure deepens over the great
plains.

a more organized low pressure system evolves over the central
great plains on thursday, tracking northeastwards and strengthening
to 29.3 inches as it crosses lake michigan late thursday night.
gusty south to southeasterly winds will occur over the southern 
half of lake michigan thursday evening as the low pressure 
approaches, veering southwesterly late. slower east winds expected
for the north half. 

as this low pressure departs northeastward (predawn friday 
morning), it swings a cold front southward across the lake, with 
gusty north to northwest winds behind it, which persist through
early friday afternoon. both of these periods of gusty winds are 
expected to be below gale force.

weak high pressure crosses the lake friday night with light and
variable winds turning east. another low pressure system tracking
northeastward from arkansas/louisiana will pass south of lake
michigan on saturday, and the west to northwest winds behind this
system (saturday night into sunday) may reach gale force over lake
michigan.

open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
240 pm cst wed jan 7 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...

a high pressure ridge averaging 30.0 inches continues eastward
from the ohio river valley and eastern great lakes this evening,
allowing a light south breeze to overspread lake michigan,
strengthening (gusts to 20 kt) on thursday as the ridge builds to
30.2 inches and a trough of low pressure deepens over the great
plains.

a more organized low pressure system evolves over the central
great plains on thursday, tracking northeastwards and strengthening
to 29.3 inches as it crosses lake michigan late thursday night.
gusty south to southeasterly winds will occur over the southern 
half of lake michigan thursday evening as the low pressure 
approaches, veering southwesterly late. slower east winds expected
for the north half. 

as this low pressure departs northeastward (predawn friday 
morning), it swings a cold front southward across the lake, with 
gusty north to northwest winds behind it, which persist through
early friday afternoon. both of these periods of gusty winds are 
expected to be below gale force.

weak high pressure crosses the lake friday night with light and
variable winds turning east. another low pressure system tracking
northeastward from arkansas/louisiana will pass south of lake
michigan on saturday, and the west to northwest winds behind this
system (saturday night into sunday) may reach gale force over lake
michigan.
