Low pressure developing over the Gulf of Mexico will move into the
Eastern Gulf Coast by Friday morning then across northeast Florida
to the Southeast Coastline by Saturday morning.  Showers and
thunderstorms with heavy rain will develop over the
Central/Eastern Gulf Coast on Friday morning will, likewise, move
eastward across Florida overnight Friday.  Additionally, moderate
to heavy rain will develop over parts of Southeast on Friday
afternoon into evening, with light rain over parts of the Southern
Mid-Atlantic Coast by Saturday morning. 

Meanwhile, a front over the Great Lakes to the Southern Plains
will move eastward to the Northern/Central Appalachians while
dissipating by Saturday morning.  Light rain will develop over
parts of the Great Lakes moving eastward to the Maine Coast by

A front moving onshore over the Pacific Northwest will move

Furthermore, a weakening upper-level low off the Southern
California Coast will move inland to the Southwest by Saturday. 
The energy will aid in producing scattered showers and

parts of the Southern High Plains by Saturday morning.  Rain will
also develop over parts of the Central/Southern Rockies and the
Southeast by Saturday morning.
