SYNOPSIS
Low pressure, 29.10 inches, will move across northern
Ontario today and into Quebec on Wednesday. This low will drive
an arctic cold front across Lake Huron Wednesday morning. The
post frontal arctic air will lead to near gale force winds,
freezing spray and snow squalls. Lingering troughing will hold
across the eastern Great Lakes through Thursday while high
pressure, 30.10 inches expands across Lake Superior. Another low
pressure system is forecast to track across the northern Great
Lakes on Friday, bringing more gusty winds and snow showers.
