waves are provided as a range of significant wave heights, which
is the average of the highest 1/3 of the wave, along with the
average height of the highest 10% of the waves which will
occasionally be encountered.

.synopsis...

29.6 inch low pressure is moving toward the ontario-quebec border
this evening, resulting in continued gusty northwest winds across
the open waters of lake michigan. said gusty winds will continue 
into sunday morning as the low deepens to near 29.2 inches over 
quebec. the potential for a few gale force gusts will continue 
through sunday morning across the northern third of lake michigan.
continue to anticipate that that headlines won't be necessary 
given the isolated nature of any such higher gusts. winds will 
taper sunday afternoon & night as 30.4 inch high pressure builds 
into the great plains. scattered rain and snow showers ongoing 
through this evening will taper through the second half of the 
overnight hours tonight. additional rain and snow showers are 
forecast sunday night into monday.

northwest winds will increase once more during the day monday as a 
small area of 30.0 inch low pressure develops over lake huron. 
similar to ongoing conditions, a few gale force gusts are possible
over the northern half of the open waters during the afternoon 
hours, but are expected to be isolated and brief enough to 
preclude the need for any headlines. trends will continue to be 
monitored. winds will decrease monday night into tuesday as 30.5
inch high pressure moves over and east of the open waters. areas 
of moderate freezing spray are possible over the northern half of 
the lake monday afternoon and evening.

29.6 inch low pressure will form over the northern great plains &
approach lake michigan tuesday night into wednesday, resulting in
increasing southerly winds across the waters. winds will remain 
gusty into wednesday night as the low passes near or just north of
northern lake michigan. will be monitoring for more widespread 
gale potential during this time frame, with the need for headlines
being evaluated as this portion of the period draws closer. winds
will taper during the day thursday, when 30.4 inch high pressure 
is forecast to move from the northern great plains toward lake 
superior. showers and a few thunderstorms are expected wednesday 
into thursday, with severe weather potential appearing low at this
time.
