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.

waterways until this evening. the ridge briefly centers over
southern lower michigan tonight, but then gets forced out on

the northern waters of lake huron which results in a few
additional light snow showers. a warm front lifts across the
great lakes region wednesday offering milder and wetter
conditions midweek.
