302 am cdt fri jun 19 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

.synopsis...

a light northwest breeze continues over lake michigan this
morning as low pressure around 29.3 inches lingers near the saint
lawrence river / gulf. winds turn south for a brief period this
afternoon as a weak trough of low pressure approaches the lake. it
crosses northern portions of the lake late tonight with nearly
calm winds underneath it and light southwest to west winds 
further south. winds then remain relatively light and variable 
until sunday. 

low pressure tracks northeastward from the central great plains 
on sunday, reaching illinois sunday afternoon then the ohio river
valley by monday morning. east winds overspread lake michigan
sunday afternoon, becoming gusty over southern portions of the
lake and turning northeast later sunday into sunday night (as the
low makes its closest approach). winds turn north and remain gusty
into monday, particularly over southern portions of the lake. 

lighter winds return tuesday and wednesday as high pressure builds
into the region.
