tonight. friday, a 30.0 inch ridge builds over the lake associated
with a 30.2 inch high over the northern canadian prairie 
provinces. friday night, ridging weakens over the lake as a 29.7 
inch low approaches the southern portions of the great lakes 
basin. as the low moves through southern lake michigan early 
saturday, an inverted 29.8 inch trough will move through lake 
superior. 30.0 inch ridge will return saturday night, then build 
to 30.1 inches sunday night. this ridge will remain over lake 
superior late weekend into early next week. a deepening low
pressure system moving into the lower midwest sometime monday
night thorough tuesday will lead to height falls over lake
superior, but exact timing and track of this system remains
uncertain.
