an upper disturbance crossing the region may bring light rain/freezing
rain to the southern half of lake michigan this morning. winds 
will continue to weaken through tonight across the lake, as weak 
high pressure around 30.3 inches develops over the area.

light south to southwesterly winds will continue across the

out of the east further south in response to developing low
pressure around 29.9 inches in the middle mississippi river 
valley. this low will pass just to the south of lake michigan 
wednesday night into thursday, allowing for east to northeast 
winds to become established. rain showers will spread north 
across the open waters as the low pressure system passes. a few 
thunderstorms are possible over far southern lake michigan 
thursday. 

low pressure around 29.5 inches will develop in the central plains
thursday night, and track toward the upper mississippi river 
valley by friday evening. this low will move near or just north 
of lake michigan later friday night into saturday morning, 
quickly moving into quebec by saturday evening. as the low passes
to the north, south to southwest winds will steadily increase 
friday afternoon into saturday morning, ultimately veering 
westerly saturday afternoon. winds will be gusty at times during 
this period, with a few gales possible friday night into saturday 
morning. widespread rain and embedded thunderstorms will accompany
the approaching and passing low friday through saturday.
