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...

breezy southwest winds continue as low pressure around 29.4 inches 
over western ontario swings into northern lake michigan this 
evening. the low will move into northern lake huron tonight and 
continue into eastern ontario by saturday. as this low moves through 
a cold front will move across the lake turning winds to the west. 
west to northwest winds will persist through saturday night. 

another low pressure system around 29.4 inches will track from 
alberta into lake superior sunday afternoon and evening. winds will 
turn to southwesterly and increase ahead of this system. a few gusts 
will approach gales sunday afternoon and evening. a cold front will 
move across the lake late sunday evening causing winds to further 
increase and turn to westerly. gales will become increasing likely 
sunday night into monday. 

as the low moves east into eastern ontario monday, strong northwest 
to west winds are expected with building waves. the pressure 
gradient will further tighten as a high around 30.5 inches 
follows on the heels of the exiting low. gales are likely during 
this time. freezing spray will also be expected as arctic air 
settles over the great lakes region. some heavy freezing spray is 
possible sunday night into monday. 

monday night into tuesday winds will begin to diminish and turn to 
southwesterly ahead of another low pressure system around 
29.9 inches tracking from alberta towards the great lakes.

a 29.4 inch low over western lake superior this morning will slowly 
meander over upper michigan through saturday morning, further 
weakening to 29.8 inches saturday afternoon when it reaches just 
north of gregorian bay. meanwhile, a 30.4 inch high sets up over the 
plains. while low lifts northeast through quebec saturday night, the 
high settles toward the southeast u.s., briefly extending 29.9 inch 
ridging over lake superior. this quickly is replaced by a clipper 
low of at least 29.6 inches on sunday. the low continues to quebec 
on monday as it deepens to 29.4 inches while another high pressure 
of 30.5 inches drops south over the plains. ridging of at least 30.2 
inches looks to return to the upper great lakes on tuesday.
