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...

northeasterly winds this afternoon will gradually turn more 
easterly tonight into thursday as high pressure around 30.3 
inches tracks across the region. the stronger winds are expected
across the southern half of the lake during this time. then two
areas of low pressure are progged to merge over the great lakes
region into a single low pressure for thursday and deepens to 
around 29.5 inches as it shifts into the eastern great lakes 
later thursday through friday. expect a northwesterly wind shift
to ramp up and increase to gales and nearing storm force at 
times on the backside of the departing low pressure while a 
strong high pressure around 30.7 inches builds to the west. thus
will maintain a gale watch for all the open waters of lake 
michigan friday morning into friday night.
