national weather service milwaukee/sullivan wi
215 pm cdt sat oct 31 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...

30.5 inch high pressure is centered near lake erie this 
afternoon, resulting in generally east to southeast winds across 
the open waters of lake michigan. the high will drift southeast 
into the northeastern united states through sunday, allowing winds
to trend southerly across the lake. low pressure near 29.5 inches will
develop over eastern colorado sunday evening, progressing into 
the upper mississippi river valley into early tuesday morning. 
winds will steadily become gusty ahead of the approaching low, 
approaching or exceeding gale force over at least the central 
third of the lake tuesday afternoon and evening. anticipate that 
headlines will become necessary in later forecasts. 

winds will remain breezy, though likely below gale levels wednesday 
and wednesday night as 30.1 inch high pressure slowly builds into
the canadian great plains. said high will move into the western 
great lakes through the second half of next week, allowing for 
westerly and eventually north winds by next weekend.
