possible. winds diminish overnight as a ridge of high pressure 
around 30.0 inches moves into the region. winds become 
southwesterly again as an additional low pressure system moves 
through the canadian prairies on monday, shifting to northwesterly
monday night as low pressure exits into ontario and another cold 
front sweeps southeastward. winds then shift westerly through 
tuesday into tuesday night before turning northerly as low 
pressure deepens in the southeast u.s. on wednesday. wednesday 
into thursday, expect a strong band of lake effect snow and rain 
to develop north to south. gales are possible on thursday.

.synopsis...

low pressure of 29.4 inches over the canadian prairies will move
east through ontario overnight, bringing steady southwesterly
winds to lake michigan. a cold front from this low will shift
winds to west-northwesterly into sunday, with gusts up to 30 kt
possible. winds diminish overnight as a ridge of high pressure 
around 30.0 inches moves into the region. winds become 
southwesterly again as an additional low pressure system moves 
through the canadian prairies on monday, shifting to northwesterly
monday night as low pressure exits into ontario and another cold 
front sweeps southeastward. winds then shift westerly through 
tuesday into tuesday night before turning northerly as low 
pressure deepens in the southeast u.s. on wednesday. wednesday 
into thursday, expect a strong band of lake effect snow and rain 
to develop north to south. gales are possible on thursday.
