evening. following the passage of a weak warm front, a 30.2 inch 
high will build across the great lakes region thursday and thursday

the lower lakes friday, with another 29.6 inch low then moving from 
near james bay to the canadian maritimes between saturday and sunday 
and pushing a cold front across the lake. a 30.4 inch high is then 
forecast to build across the great lakes on monday.
