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

.synopsis...

breezy northerly winds continue as a tight pressure gradient 
remains over lake michigan between low pressure of 29.8 inches 
over lake huron and high pressure of 30.3 inches over the 
northern plains. northerly gales around 35 kt are expected to 
linger through this afternoon as the pressure gradient remains 
over the lake, and a gale warning remains in effect. winds will
diminish from north to south this afternoon. middle and southern
portions of the lake will continue to see waterspout potential

high pressure then builds over the upper great lakes this

winds. low pressure around 29.4 inches crossing ontario will drag
a weak cold front across lake michigan on sunday. highest gusts 
up to 30 kt are expected over the north half. the next low 
pressure system will cross lake superior monday night.
