moves eastward across the northern great lakes. this low should move 
generally east-southeastward from near the northern great lakes to 
near the gulf of maine later sunday through this monday. the low 
track should allow a cold front to sweep eastward across lake 
ontario sunday evening through sunday night. behind the cold front, 
a high pressure ridge averaging 30.0 inches should attempt to build 
from the upper midwest through monday. the high is expected to move 
off the east coast tuesday.
