no major changes to the going forecast this morning.

southerly winds will increase this morning, as low pressure 
around 29.7 inches approaches the lake. the low pressure system 
will drag a cold front southeast over the region later this 
morning into late this afternoon. southwest to south winds may 
approach gale force at times over the southern half but with the 
cooler lake conditions winds should largely stay below gale force.
winds will become westerly for a brief period behind the front
later tonight, before returning to southwesterly and becoming 
breezy again on monday ahead of another stronger low around 29.2 
inches and another cold front. light and more variable winds
should be expected to return to the region through at least the
middle of the week given weak high pressure over the region.
