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...

areas of fog will continue over the lake into friday due to 
relatively mild and moist air flowing over the cold lake. modest 
south to southeast winds will persist into friday as a trough of 
low pressure and cold front approaches from minnesota and iowa. 
however, breezy easterly winds are expected over the northern tip 
of the lake through friday afternoon, as the warm front will 
stall before reaching the upper peninsula. 

the low will pull a cold front across lake michigan friday afternoon 
and evening, resulting in modest northwest to north winds. 
showers and thunderstorms are expected late tonight through 
friday, both ahead of and along the front. severe weather is not 
anticipated at this time.

light north winds on saturday will then become easterly saturday
night and sunday before increasing into monday. 29.4 inch low 
pressure is forecast to track northeastward from the central great
plains (sunday night) near or over lake michigan (monday night), 
with gusty east to southeast winds ahead of its arrival and gusty 
west winds behind it (into tuesday). not seeing widespread gale 
potential with this system, though trends will be monitored.
