825 pm cst sun dec 16 2018

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...

strong low pressure of 29.0 inches over hudson bay will push into
northern quebec on monday. a trailing cold front will move across
the lake this evening into tonight, with gusty northwest winds as
the front passes. a period of gales to 35 knots is expected this
evening into tonight across the northern third of the lake, with
winds to around 30 knots expected further south. 

look for the northwest winds to settle down monday afternoon 
as high pressure of 30.3 inches moves across lake michigan monday
night. brisk south to southwest winds will prevail for tuesday 
afternoon through wednesday as low pressure of 29.5 inches moves 
east across southern canada.

by late in the week, low pressure of 29.4 inches is expected to
develop across the southern united states, and then lift north
into the upper ohio valley while deepening to around 29.1 inches.
this would likely result in a period of north gales across lake
michigan late in the week into next weekend.
