open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
303 am cst thu jan 29 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...
light to moderate west northwest winds prevail over lake michigan
through this evening as a weak low pressure around 30.0 inches in
the eastern great lakes region moves into the northern new
england states. meanwhile a broad high pressure around 30.5 inches
stretches from the northern plains into the lower missouri river
valley. this high pressure will strengthen friday to around 30.6
inches as a low pressure system around 30.0 inches in the mid
mississippi river valley moves east into to the mid atlantic
coast. these two systems will briefly turn winds to the north to
northeast across lake michigan. during this time lake effect snow
will develop and wobble across the lake.
winds shift back to north- northwesterly and increase friday
night as low pressure deepens to 29.8 inches off the coast of the
mid atlantic states. moderate to heavy freezing spray will likely
develop during this time. a second brief period of northeast
winds is possible saturday morning as the high pressure around
30.6 inches in the great plains slides southward into the u.s.
southeast and low pressure in the atlantic further deepens. winds
become light and variable saturday night into sunday as the high
pressure finally dominates the pattern.
