waves are provided as a range of significant wave heights, which

average height of the highest 10% of the waves which will
occasionally be encountered.

.synopsis...

southerly winds will persist this morning as high pressure moves 
into the ohio river valley. winds will continue to veer through 
today, with southwesterly readings becoming established as 29.7 
inch low pressure moves from the southern hudson bay into quebec. 
gusts between 25-30 knots are possible over the northern third of 
lake michigan after dawn this morning and into the early 
afternoon, though gales are not anticipated. 

winds will trend light and variable friday evening into saturday 
as 30.2 inch high pressure approaches and ultimately crosses the 
open waters. winds will veer south to southwesterly ahead of a 
weak cold front saturday night. the front is forecast to cross the
waters early sunday morning, bringing a brief northwesterly wind 
shift during the afternoon hours. winds will shift back to the 
southwest sunday night through monday, when 29.6 inch low pressure
is forecast to develop over northern ontario. 

stronger low pressure near 29.2 inches will form over the 
northern great plains during the day on tuesday, resulting in 
increasing southeasterly winds over lake michigan. winds will 
continue to increase tuesday night into wednesday as the low 
approaches and eventually crosses lake michigan. the low will 
progress east of the waters wednesday afternoon & evening, 
resulting in a gusty east-northeast wind shift wednesday night 
through thursday morning. a few gale force gusts are possible 
tuesday night through thursday morning, with trends being 
monitored for possible headlines over coming forecasts. rain and 
snow will accompany the approaching passing/low tuesday evening 
through thursday, with a few rumbles of thunder possible tuesday 
evening through wednesday. pockets of light to moderate freezing 
spray are possible late wednesday night into thursday morning over
the northern half of the waters.
