...There is a Slight Risk (level 2/5) of severe thunderstorms over parts
of the Southern Plains on Saturday and Sunday...

... There is a Slight Risk (level 2/4) of excessive rainfall over parts of
the Lower Mississippi Valley on Saturday and Sunday...

A front lingering along the Gulf Coast will produce showers and
thunderstorms from the Southeast to the Southern Plains through Sunday.
Heavy rain will accompany the thunderstorms producing heavy rain.
Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive
rainfall over parts of the Lower Mississippi Valley on Saturday and
Sunday. The associated heavy rain will create mainly localized areas of
flash flooding, with urban areas, roads, small streams, and low-lying
areas being the most vulnerable. 

In addition, showers and severe thunderstorms will develop over parts of
the Southern Plains on Saturday. Therefore, the SPC has issued a Slight
Risk (level 2/5) of severe thunderstorms over parts of the Southern Plains
from Saturday into Sunday morning.  The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts,
hail, and a few tornadoes.

On Sunday, showers and severe thunderstorms will redevelop over parts of
the Southern Plains and the Lower Mississippi Valley. Therefore, the SPC
has issued a Slight Risk (level 2/5) of severe thunderstorms over parts of
the Southern Plains and the Lower Mississippi Valley from Sunday into
Monday morning.  The hazards associated with these thunderstorms are
frequent lightning, severe thunderstorm wind gusts, hail, and a few
tornadoes.

Meanwhile, a front extending from the Great Lakes to the Northern High
Plains will move southward to the Gulf Coast and eastward to the Eastern
Seaboard by Monday. The boundary will produce scattered rain from the
Great Lakes to the Northern High Plains on Saturday morning. Showers and
thunderstorms will also develop along the front in the late afternoon into
the late evening.

As the front moves to the East Coast, rain will develop over the Northeast
on Sunday into Monday. Showers and thunderstorms will develop over parts
of the Mid-Atlantic on Sunday afternoon and continue over the Southeast
into Monday morning.
