south of the lake, will then carry the front southeast of the lake 
this evening. a 30.4 inch high will then build from northwest 
ontario province thursday night to southern quebec by saturday 
morning before moving off the new england coast by sunday while 
weakening to 30.2 inches. another 30.4 inch high will then build 
from northwest ontario province sunday to western quebec monday. 
meanwhile, a 29.8 inch low will move into the lower ohio valley by 
monday.
