A storm over the Tennessee Valley will slowly move eastward to the
Southeast/Southern Mid-Atlantic by Tuesday evening.  Showers and
thunderstorms will develop along and ahead of the associated front
over parts of the Tennessee Valley into the Southeast moving off
most of the Southeast Coast except for parts of the Florida
Peninsula and the Southern Mid-Atlantic by Tuesday evening.  Rain
will also develop over parts of the Middle Mississippi and Ohio
Valleys that will expand into parts of the Central Appalachians
and the Northern Mid-Atlantic by Monday evening.  The rain will
move into parts of the Great Lakes and the Northeast on Tuesday
morning into Tuesday evening.

Meanwhile, upper-level energy over the Northern Rockies will move
southeastward to the Central Plains/Central Rockies by Tuesday
evening.  The energy will aid in producing higher elevation snow
and lower elevation rain over parts of the Northern
Rockies/Northern High Plains that will move southeastward into
parts of the Central Rockies overnight Monday into Tuesday
evening.
