306 am cst wed dec 11 2019

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... 

low pressure of 29.9 inches is passing to the north of the great 
lakes and will move east into quebec today. moderate westerly 
winds will continue this afternoon and combined with the colder 
temperatures, freezing spray will be possible at times through 
this evening. a surface high pressure of 30.6 inches will push 
across the northern great plains and move across lake michigan 
tonight. the winds will diminish and back to the south overnight 
as another weak surface low of 30.0 inches approaches the region. 
southerly winds will increase for thursday as the low pushes 
across lake michigan. gale force gusts are possible, especially 
over the center and south half of the lake, thus a gale watch is 
in effect for the southern 2/3rds of lake michigan thursday 
morning through thursday afternoon. the low will then move east of  
the lake thursday night and lighter winds are expected by friday
with northwesterly winds developing by the weekend.
