Synopsis
30.7 inch high pressure is centered over Quebec today, keeping a 30.5 inch ridge over Lake Superior along with mainly easterly winds. The Quebec high begins to break down Thursday morning, weakening to 30.4 inches by Thursday night as winds veer southerly. By late Friday, the high weakens to 30.2 inches over the eastern Great Lakes basin as 29.5 inch low pressure develops over Montana. Southerly flow persists through Saturday as the high deteriorates further and the Montana low pressure deepens and moves north through the Canadian Prairies. By Sunday morning, high pressure shifts northeast, leaving pressure to 30.1 inches over Lake Superior, which decreases to 30.0 inches by Monday morning as the high shifts toward the Canadian Maritimes.
