.synopsis...

modest south to southwest winds will continue today as low
pressure progresses into the hudson bay. a weak cold front will
gradually shift winds to northerly tonight before high pressure
around 30.3 inches builds into ontario and pushes a stronger cold
front southward over lake michigan wednesday afternoon and 
evening. brisk north to northeast winds can be expected along this
front. modest northerly winds will continue into thursday, 
becoming light by thursday night. 

another potential cold front may shift southward across the lake 
on friday, as another high pressure system around 30.3 inches 
develops to the north of the region. this may bring another round 
of brisk north to northeast winds behind it through saturday.

waves are the significant wave height - the average of the
highest 1/3 of the wave spectrum. occasional wave height is the

.synopsis... 

lake superior will remain under the influence of 29.8 inch troughing 
until tonight, when weak ridging of 30.1 inches builds in over lake 
superior thanks to a 30.4 inch high over the western shores of 
hudson bay. this parent high then shifts southward over lake 
superior on thursday, causing pressure to increase to 30.3 inches. 
on friday, the high weakens to around 30.1 inches as it continues 
its southerly propagation. following this, a second ridge pushing in 
from hudson bay brings 30.1 inch ridging back over lake superior 
late on friday, with the ridging increasing once again to 30.3 
inches by saturday midday as the parent high over hudson bay pushes 
south. by sunday morning, this ridging decreases to 30.1 inches as 
the parent high moves toward the lower great lakes.
