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...

30.4 inch high pressure is centered over the upper mississippi 
river valley this morning, with 30.1 inch low pressure along the 
ontario-quebec border. placement of the two features is resulting
in generally light northerly winds across the open waters. winds 
will weaken further tonight, becoming light and variable wednesday
morning as the aforementioned area of high pressure moves across 
lake michigan. lake effect snow is possible over the southern half
of the open waters wednesday morning and afternoon. winds will 
trend west-southwesterly wednesday night into thursday as 29.5
inch low pressure moves from the canadian great plains to the 
western hudson bay. areas of snow are possible during the day on 
thursday ahead of the developing low.

low pressure will deepen further to near 29.3 inches over the 
central hudson bay thursday night, ultimately progressing into 
northern quebec during the day on friday. the low will pull a cold
front across the open waters in the process, resulting in a gusty
northwest wind shift early friday morning. a period of 
northwesterly gales remains possible during the afternoon and 
evening hours, with trends being monitored for potential headlines
in coming forecasts. areas of snow showers will continue along & 
ahead of the passing front thursday night into early friday 
morning. elevated wave heights will combine with arctic air 
settling in behind the cold front to support areas of moderate 
freezing spray friday afternoon into saturday morning. heavy 
freezing spray is possible, with the need for possible headlines 
being evaluated in coming forecasts. winds will briefly taper 
saturday afternoon as 30.4 inch high pressure crosses lake 
michigan, prior to increasing once more saturday night as the 
feature moves east of the waters.
