waves are provided as a range of significant wave heights, which

average height of the highest 10% of the waves which will
occasionally be encountered.

.synopsis...

no major changes to the going forecast this morning.

northerly winds will remain steadily breezy (though below gale 
thresholds) through today and into saturday with high pressure of
30.4 inches positioned well to the northwest. winds will taper 
sunday into monday as 30.5 inch high pressure builds directly over
the open waters.

persistent northerly winds will allow for continued lake effect 
precipitation today. low level temperatures will be supportive 
for mainly rain, though some snow could mix in over the northern 
half of the lake. a few thunderstorms are possible, particularly 
over the southern half of the waters. can't rule out a waterspout 
in any deeper thunderstorms that manage to develop.
