inch high over the tennessee valley will slide out across new 
england today...while a surface trough averaging 29.8 inches passes 
just to the north of the lake. another 29.3 inch low will then move 
from western ontario tuesday to southern quebec wednesday. this 
system will push its trailing cold front across the lake wednesday 
night, when a secondary 29.4 inch coastal low will develop along the 
mid-atlantic coastline. this secondary low will then track northeast 
to the gulf of maine thursday and to newfoundland friday...while 
30.0 inch high pressure slowly builds east across the great lakes.
