.synopsis...

low pressure around 29.5 inches sits over mn/ia this evening.  
this will drive gusty southerly winds across the lake through 
wednesday. gales have ended across the lake though gusty winds to
30 kts will remain possible through wednesday night as the low
pivots north to the upper peninsula and deepens to 29.4 inches.
this system will weaken somewhat as it tracks east and gradually
pushes out of the area thursday night into friday. on the backside
of this low pressure system expected a period of breezy north
winds. perhaps a few gales will be possible, particularly on the
northern side of the lake earlier on and then becoming likely
during the day friday. gale warning may be needed for friday.

otherwise, expect periods of rain and perhaps a few rumbles of 
thunder will accompany low pressure tonight through midweek.
