open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
245 pm cdt wed apr 2 2025
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 gale warning remains in effect for the entire open waters
until 0z, lingering longer in the far north. the surface low of
29.2 inches will progress toward lake superior this evening,
moving into ontario by early thursday morning. we cannot rule
out a few stronger storms across the far southern portions of
the lake late this afternoon into the evening. winds will turn
southwesterly & gradually decrease in the wake of the departing
surface low tonight.
30.1 inch high pressure will build into the northern great plains
thursday afternoon, allowing winds to turn more westerly across
the open waters. there is increasing potential for a period of
gales in the far north early thursday lasting into the
afternoon. thus we have issued another gale warning for the
northern parts of the lake from 9-19z. winds will become light
& variable thursday night as the high crosses lake michigan.
winds will shift out of the northeast on friday as low pressure
forms in the southern great plains. winds will increase during
the day on saturday as the low moves into the ohio river valley.
gales aren't forecast at this time, though trends will be
monitored. periods of rain will accompany the approaching low
friday afternoon through saturday, with a few thunderstorms
possible over far southern lake michigan.
