low pressure around 29.5 inches over lower mi will continue to 
lift eastward up the st. lawrence river valley tonight. winds will
remain breezy and out of the northwest this evening accompanied 
by some rain and fog, where we cannot rule out seeing some pockets
of dense marine fog at times given the warm air moving in 
overnight. winds will also weaken and turn westerly into early 
wednesday morning before turning southwesterly as high pressure 
around 30.1 inches treks up the ohio river valley through the day 
wednesday. will see breezy south-southwesterly winds continue into
thursday before another low pressure around 29.6 inches tracks up
from the central plains and across the southern tip of lake 
michigan thursday night. behind this low pressure expected winds 
to increase and turn more northerly for friday before gradually 
easing friday afternoon and turning more easterly ahead of another
developing low pressure. this system is progged to lift from 
southern plains up into the eastern great lakes for saturday 
bringing a return of stronger northerly winds with the next 
potential to see some gales over the open waters of lake michigan
through saturday night.
