...elevated waves continue this morning over southern lake 
huron...

.canadian high pressure will expand into the northern great lakes 
over the next couple days before departing to eastern canada over 
the weekend. this system will influence the region right through the 
end of the weekend. there is an ongoing push of seasonally cool air 
across the lakes as this high builds in. this is currently 
supporting gusty northerly winds across southern lake huron. the 
winds and waves will gradually decrease during the course of the day 
and into tonight as the gradient slowly relaxes. light to modest 
northerly winds will however persist across the the lakes through 
the day friday. persistent cold air advection across the lakes today 
into friday will promote enough over lake instability to support a 
chance for waterspouts.
