...There is a Slight Risk (level 2/4) of excessive rainfall over
parts of the Southern on Saturday and the Great Lakes,
Upper/Middle Mississippi Valley on Sunday...

Low pressure over the Mid-Atlantic will move eastward out over the
Atlantic overnight Saturday. The system will produce rain over the
northern Mid-Atlantic/Northeast and showers and thunderstorms from
Virginia southward to the Gulf Coast. Showers and thunderstorms
will linger over the Southeast through Monday morning, while rain
showers linger over the Northeast and Mid-Atlantic Coast through
Monday.

Another low over the Southern Plains will lift northward to the
Upper Mississippi Valley by Monday evening. Showers and severe
thunderstorms will develop over parts of the Southern Plains on
Saturday. Therefore, the SPC has issued a Moderate Risk (level
4/5) of severe thunderstorms over parts of the Southern Plains
through Sunday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind
gusts, hail, and a few tornadoes.

In addition, the showers and thunderstorms will produce heavy
rain. Therefore, the WPC has issued a Slight Risk (level 2/4) of
excessive rainfall over parts of the Southern Plains and adjacent
Lower Mississippi Valley through Sunday 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 Sunday, showers and severe thunderstorms will develop over
parts of the Central Plains and adjacent Middle Mississippi
Valley. Therefore, the SPC has issued an Enhanced Risk (level 3/5)
of severe thunderstorms over parts of the Central Plains and
adjacent Middle 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.

On Monday, showers and severe thunderstorms will once again
develop over the Middle Mississippi Valley and Western Ohio
Valley. Therefore, the SPC has issued an Enhanced Risk (level 3/5)
of severe thunderstorms over parts of the Middle Mississippi
Valley and Western Ohio Valley on Monday. The hazards associated
with these thunderstorms are frequent lightning, severe
thunderstorm wind gusts, hail, and a few tornadoes.

Moreover, the showers and thunderstorms will produce heavy rain
over the region. Therefore, the WPC has issued a Slight Risk
(level 2/4) of excessive rainfall over parts of the Upper/Middle
Mississippi Valley and Upper Great Lakes on Monday. 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 energy moving onshore over California on
Saturday will move to the Upper Midwest by Monday evening. The
system will produce rain with embedded thunderstorms over parts of
Northern California and Nevada on Saturday and Sunday. The system
will produce late-season light snowfall over the higher elevations
of the Northern Rockies, the Northern Intermountain Region, the
Sierra Nevada Mountains, the Great Basin, and the Central Rockies
Saturday into Sunday.
