903 am cdt fri may 1 2026

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...

no major changes to the going forecast this morning.

high pressure around 30.2 inches continues to sit over central 
canada through the end of the week and will bring light and 
varying winds across lake michigan through today. high pressure 
begins to work its way southeastward tracking across lake michigan
tonight through the day saturday. will begin to see more 
southerly winds develop saturday night and pick up into sunday as 
the high pressure continues to track southward while low pressure 
around 29.4 inches treks across ontario. this looks to drag a cold
front week cold front across the lake later sunday turning winds 
more westerly briefly, before another low pressure around 29.1 
inches develops right behind it for monday. expecting a stronger 
cold front to move across the lake through the day monday and turn
winds north-northwesterly overnight into tuesday.
