open lake forecast for lake huron
national weather service detroit/pontiac mi
335 am edt fri apr 3 2026

for waters beyond five nautical miles off shore on lake huron

waves are the significant wave height - the average of the highest
1/3 of the wave spectrum. occasional wave height is the average of
the highest 1/10 of the wave spectrum.

.synopsis...a low pressure system crossing northern lake huron
will drag a cold front across the central great lakes today.
drier conditions are expected through the daylight hours before
unsettled weather returns friday night. the next warm front
slowly lifts into the southern waterways aloft, well ahead of the
surface boundary, triggering some nocturnal showers and perhaps a
few thunderstorms. the associated trailing surface low should
reach southern lake michigan by saturday morning as the elevated
warm front continues to track northward across lake huron. some
strong to marginally severe thunderstorms should affect the
waterways late tonight and saturday morning, before one final
round develops saturday evening with the passage of its cold
front.
