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...an elongated trough axis expands into the southern

active stretch of weather gets underway tonight into wednesday as
low pressure, 29.50 inches, lifts across lower michigan. expect
several rounds of showers and thunderstorms, including some
strong to severe storms. all severe hazards will be possible. the
system's frontal passage eventually leads to a transition to
melting snowfall by wednesday evening. seasonably cool conditions
ensue thursday, followed by more rain, snow, and wind with
another system on friday.
