.synopsis...

high pressure of 30.2 inches over the southeastern us will drift

east across the northern great lakes through friday bringing 
prevailing southwesterly winds to lake michigan along with shower 
and thunderstorm chances tonight through friday ahead of the cold 
front. then expect the cold front to push through the region later
friday into saturday bringing additional shower and thunderstorm 
chances along with a more northwest to westerly wind shift behind 
it into saturday. then winds weaken and become more variable as 
high pressure around 30.0 inches builds across the region later 
saturday into sunday. looking ahead to the start of next week will
bring an additional low pressure system to develop over the 
plains and bring a return of southerly winds to the upper great 
lakes.
