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

.synopsis...

gusty northwest winds will continue early this morning, as low 
pressure strengthens to around 29.3 inches off the mid-atlantic 
coast and strong high pressure over manitoba builds to around 31.1
inches. 

as the high pushes eastward into ontario tonight, expect gales to
develop across the southern two-thirds of the open waters of lake
michigan. a gale warning is now in effect this evening into 
midday monday. moderate freezing spray is also expected, with some
heavy freezing spray possible in the central to northern third of
the lake.

winds will gradually diminish into monday, as strong low pressure
around 28.7 inches moves toward nova scotia and high pressure 
around 30.6 inches lingers over the western great lakes region. 

a modest south wind develops tuesday, as the strong high pressure
system continues eastward and weak low pressure around 29.5 
inches moves eastward through the northern great lakes. a cold 
front from this low will turn winds northwesterly again tuesday 
night into wednesday morning.
