...There is a Slight Risk (level 2/5) of severe thunderstorms over
the Northern Plains, parts of Iowa, and South Carolina on Sunday...

...There is a Slight Risk (level 2/5) of severe thunderstorms over
the Upper Midwest on Monday...

...There is a Slight Risk (level 2/4) of excessive rainfall over
parts of the Mid-Atlantic, Tennessee Valley, and Northern High
Plains through Monday morning...

A slow-moving front across the Northern Plains will produce severe
thunderstorms. Therefore, the SPC has issued a Slight Risk (level
2/5) of severe thunderstorms over parts of the Northern
Plains/Middle Mississippi Valley on Sunday into Monday morning. 
The hazards associated with these thunderstorms are frequent
lightning, severe thunderstorm wind gusts, hail, and a few
tornadoes. 

Moreover, the WPC has issued a Slight Risk (level 2/4) of
excessive rainfall over parts of the Northern High Plains Sunday
through Monday morning. 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.

Meanwhile, an upper-level low over the Northwest will help produce
rain and higher-elevation snow over parts of the Northern Rockies
and Northern Intermountain Region Sunday evening into Monday. The
energy will also develop showers and thunderstorms over parts of
the Northern High Plains on Monday into Tuesday.

Furthermore, upper-level energy over the Carolinas will trigger
showers and severe thunderstorms with heavy rain over parts of the
Southern Mid-Atlantic. Therefore, the SPC has issued a Slight Risk
(level 2/5) of severe thunderstorms over parts of South Carolina
on Sunday into Monday morning.  The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind
gusts, hail, and a few tornadoes. 

Additionally, the WPC has issued a Slight Risk (level 2/4) of
excessive rainfall over parts of the Southern Mid-Atlantic.
Therefore, the WPC has issued a Slight Risk (level 2/4) of
excessive rainfall over eastern North Carolina on Sunday into
Monday morning.  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.

What is more, WPC has issued a Slight Risk (level 2/4) of
excessive rainfall over parts of the Central Appellations and
eastern Tennessee Valley through Monday morning. 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.

On Monday, an area of strong low pressure over the Northern Plains
into the Upper Mississippi Valley will add in producing severe
thunderstorms over the region. Therefore, the SPC has issued a
Slight Risk (level 2/5) of severe thunderstorms over parts of the
Northern Plains, Upper/Middle Mississippi Valley on Monday into
Tuesday morning. The hazards associated with these thunderstorms
are frequent lightning, severe thunderstorm wind gusts, hail, and
a few tornadoes. 

On Tuesday, showers and thunderstorms will extend along and ahead
of the front as it moves into the Upper Great Lakes, Upper/Middle
Mississippi Valley, and parts of the Central Plains. Upper-level
energy over the Northeast will produce showers and thunderstorms
over the area.

Overnight Monday into Tuesday, a weak front will linger over the
Southeast, developing showers and thunderstorms over the Southeast
and Central/Eastern Gulf Coast. In addition, Gulf moisture
streaming northward into the Southern Plains will produce showers
and thunderstorms along and east of the Dryline.
