.SYNOPSIS...High pressure, 30.20 inches, over Quebec will move to
the Canadian Maritimes by Thursday morning. A ridge of high
pressure, 30.10 inches, will extend across the eastern Great

forecast to move from the central Plains Friday into the western
Great Lakes Saturday. This system will result in windy conditions
and periodic showers through the weekend.
