.synopsis...

no major changes to the going forecast at this time.

brisk north to northeast winds are expected today as high 
pressure around 30.7 inches builds over ontario. breezy easterly 
winds are then expected tonight into thursday between the high 
east of james bay in canada, and low pressure of 29.4 inches 
lifting from the central plains into wisconsin. gusts appear more 
likely to reach gale force over far northern lake michigan on 
thursday and thus a gale watch continues for thursday morning 
through most of the afternoon. 

the breezy easterly winds will shift southerly from south to 
north across the lake thursday afternoon into the evening with the
passage of a warm front, then followed by the cold front with 
winds shifting westerly late thursday night. precipitation is 
expected wednesday night through thursday with a chance for some 
freezing rain toward far northern parts of the lake, particularly
thursday morning. then expect some storm chances primarily over 
the southern half of the lake thursday afternoon and evening as 
the 29.5 inch low pushes through the northern lake thursday night.
