the low lifts to james bay tuesday as 30.1 inch high pressure builds 
over the canadian rockies. as the high shifts to the canadian 
prairie wednesday, the low continues lifting into northern quebec. 
thursday into friday, the weather pattern becomes nebulous as major 
pressure systems remain far away from the upper great lakes.
