.SYNOPSIS...A weak cold front, averaging 29.90 inches, is settling
south of Lake Erie this evening. Weak high pressure will build in
behind this front and hold over the northern Ontario through
Wednesday. Low pressure will then organize over the central
plains and deepen to 29.50 inches as it tracks into the northern
Great Lakes by early Friday morning. A warm front will lift north
into the region during this time frame with a trailing cold front
pushing back south through the area on Friday in the wake of the
passing low pressure system.
