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 overnight into sunday, 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 sunday night, expect 
gales to develop across the southern two-thirds of the open waters
of lake michigan. a gale watch is in effect sunday night into 
midday monday. moderate freezing spray is also expected, with 
some heavy freezing spray possible in the central 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 breeze 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.
