national weather service milwaukee/sullivan wi
843 am cdt fri jul 10 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...

high pressure of 30.0 inches over the great lakes this morning will 
strengthen to 30.2 inches this weekend while remaining in place. the 
high will largely stay put through the first half of next week,

approaching trough of low pressure. northerly winds generally under 
15 knots through at least saturday will become southerly by monday, 
increasing a bit early next week.
