of the Northeast by Monday.  Rain will also develop over parts of
the Upper Mississippi Valley to parts of the Middle Mississippi
Valley that will move southeastward to parts of the
Mid-Atlantic/Southeast by Monday morning and off the coast by
Monday evening.  Overnight Sunday, showers and thunderstorms will
develop along the boundary over parts of the Lower
Mississippi/Tennessee Valleys that will move to Southern Georgia
by Monday evening. 

Meanwhile, a second front over Central Canada will move southward
to the Great Lakes to parts of the Upper Mississippi Valley on
