.synopsis...

high pressure over the upper great lakes will continue to
strengthen to 30.1 inches today. warm and humid air lingering 
over the relatively cool waters of lake michigan will likely cause
marine fog over the north half of lake michigan. a marine dense 
fog advisory remains in effect until midday. 

broad low pressure over the great plains and high pressure over 
the northeastern states will lead to modest southeast winds over 
the lake late tonight through tuesday. 

occasional chances for showers and thunderstorms are in the 
forecast, particularly late monday through monday night.
additional chances later in the week.
