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...

wildfire smoke from northern mn and northwestern ontario will 
continue to reduce visibility across the northern third of the 
open waters to 1 nm or less at times. thus a marine dense smoke 
advisory continues. smoke is expected to continue to spread 
southward, but uncertain on how low visibilities will fall for the
southern portions of lake michigan. we may need to expand the
advisory and we will continue to monitor lake visibilities today.

otherwise, lighter winds expected again today as another high 
pressure around 30.1 inches briefly builds back into the region 
before influence from a low pressure around 29.7 inches developing
over the northern plains pushes eastward through the weekend 
bringing more southwesterly flow for friday into saturday. then as
the low tracking northeastward, it will drag a cold front across 
the lake resulting in northerly wind shift through the day 
saturday with another high pressure building over the region for 
sunday. additionally will see periodic shower and thunderstorm 
chances across the lake for the end of the week through the 
weekend.
