.synopsis...

low pressure around 29.5 inches will meander across northern

knots at time today/tonight. low pressure will continue to slowly
trek across ontario/quebec for thursday and drag a cold front 
across lake michigan later thursday into friday. expect lighter 
but still breezy winds to gradually turn westerly as the cold 
front approaches thursday afternoon before increasing and shifting
northerly overnight into friday. will see gusts around 30 knots 
spread down lake michigan on friday as the low pressure and cold 
front slide further east. there will be a potential for gale force
gusts during the day friday and will continue to monitor trends, 
but a gale headline may be warranted. then high pressure around 
30.3 inches is progged to build across the upper great lake region
through the weekend bringing lighter northwesterly winds.
