.SYNOPSIS...A cold front will continue to sag slowly through the area this
afternoon as low pressure lifts into Quebec. This front will stall
over the Ohio Valley this evening as a second low near 29.80 inches
moves in from the midwest. Once this low digs southeast on Friday,
the cold front will continue south and a large high pressure system,
30.20 inches, will build into the central Great Lakes and remain in
place through the upcoming weekend.
