.synopsis...

low pressure around 29.5 inches will quickly deepen to 28.8 inches 
as it moves from southern lake michigan to lake huron from this 
afternoon into monday morning. as this deepening occurs, a very 
strong pressure gradient is expected to move over lake michigan, 
causing widespread northwesterly storm force winds. gales should 
begin over the southern end of lake michigan around 7pm cst tonight 
and quickly spread northward over the lake. storm force winds are 
then anticipated to start around 3am cst and continue into monday 
afternoon. winds will back off slightly from storms to gales late
monday afternoon and then continue into early tuesday. a storm 
warning has been issued for all of lake michigan tonight into 
early tuesday. marine dense fog is also expected to linger over 
the southern half of lake michigan through the rest of the 
afternoon until winds increase this evening. a marine dense fog 
advisory is ongoing. 

after the period of storms and gales, breezy northwest flow below 
gale force will last late into the week.
