waves are the significant wave height - the average of the highest

.synopsis...high pressure will wash out into the west atlantic
through the end of the week while a low pressure system moves
from the northern plains into west ontario. this will strengthen
the pressure gradient over the great lakes, increasing wind
speeds through the afternoon and evening. low pressure, 29.20
inches, will then rapidly develop and move over michigan sunday,
bringing increasing potential to see gales for a greater portion
of the region.

for waters beyond five nautical miles of shore on lake michigan.

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...

high pressure around 30.1 inches continue to work eastward across
the eastern great lakes. breezy southeast to southerly winds will
continue tonight and pick up to around 20-30 knots across lake 
michigan into friday as a deepening surface low to around 29.2 
inches lifts across western ontario while dragging a cold front 
across the western great lakes. while cannot rule out seeing a few
gale force gust later friday and overnight, think it would be 
brief, thus will hold off on any headlines at this time. winds 
will briefly weaken as the cold front slides down the lake through
the day saturday with a northwest wind shift behind it. however, 
the front may stall across the southern tip of lake michigan 
saturday so may see more southerly flow toward the southern end 
during this time. however, another strong, deepening low pressure
around 29.2 inches is then progged to work its way across lake
michigan later saturday into sunday. this will bring stronger
northwesterly winds across the lake. gale force gusts are likely
to develop across eastern portions of the lake and headlines are 
looking increasingly likely sunday into monday morning.
