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 and cold front work through the
central great lakes, supporting continued showers and
thunderstorms into the evening and early overnight hours. a brief
break in activity emerges wednesday with weak high pressure. a
secondary stronger low pressure system follows late wednesday
into thursday, capable of more intense thunderstorms and stronger
non-thunderstorm winds. additional chances exist for
thundershowers over the weekend.
