.SYNOPSIS...High pressure, 30.30 inches, will remain anchored over
the eastern Great Lakes through Tuesday, providing tranquil
boating conditions. Deepening low pressure is forecast across the

front across Lake Huron. This system will cause an increase in
winds and waves and provide rain to the region late Wednesday and
Wednesday night.
