.SYNOPSIS...Low pressure averaging 29.60 inches will push northeast

on the rise as a broad surface high pressure system starts to move
east into the Midwest. Pressure is expected to average 30.20 inches
by Thursday afternoon and will increase to 30.40 inches by Friday
afternoon. High pressure will reside across the Great Lakes region
through the weekend.
