…There is a Slight Risk of excessive rainfall over parts of the Middle
Mississippi Valley/Ohio Valley and Southern Plains on Sunday…
…There is a Marginal Risk of severe thunderstorms over parts of the
Southern High Plains into Ohio Valley on Sunday and Middle Mississippi and
Ohio Valleys on Monday…
A slow-moving front extending from the Great Lakes/Ohio Valley
southwestward to the Southern Plains advances to the Lower Great
Lakes/Ohio Valley roughly southwestward to the Southern Plains by Tuesday
evening. Showers and thunderstorms will develop along the boundary from
the Great Lakes/Ohio Valley to the Southern High Plains. The showers and
thunderstorms will produce heavy rain over two areas. The first area of
heavy rain will be over parts of the Middle Mississippi/Ohio Valleys.
Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive
rainfall over parts of the Middle Mississippi/Ohio Valleys 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 the most vulnerable.
The second area of heavy rain will develop over parts of the Southern
Plains. Therefore, the WPC has issued a Slight Risk (level 2/4) of
excessive rainfall over parts of the Southern Plains 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 the most vulnerable.
Along the front showers, strong to severe thunderstorms will also develop
over parts of the Middle Mississippi/Ohio Valleys to the Southern Plains.
Therefore, the SPC has issued a Marginal Risk (level 1/5) of severe
thunderstorms over parts of the Middle Mississippi Valley to the Southern
Plains through Monday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts,
hail, and a minimal threat of tornadoes.
On Monday, showers and thunderstorms will develop along the boundary from
parts of the Mid-Atlantic, Central Appalachians, Ohio Valley/Lower Great
Lakes, and into parts of the Middle/Lower Mississippi Valley and Southern
Plains. Strong to severe thunderstorms will develop over parts of the Ohio
Valley and Middle/Lower Mississippi Valley. Therefore, the SPC has issued
a Marginal Risk (level 1/5) of severe thunderstorms over parts of the Ohio
and Middle/Lower Mississippi Valleys from Monday through Tuesday morning.
The hazards associated with these thunderstorms are frequent lightning,
severe thunderstorm wind gusts, hail, and a minimal threat of tornadoes.
Moderate to heavy rain will also develop over parts of the Middle
Mississippi Valley, Ohio Valley, and Central Appalachians.
On Tuesday, showers and thunderstorms will continue along and near the
front from parts of the Lower Great Lakes, Ohio Valley, Central
Appalachians, Mid-Atlantic, and from the Central Gulf Coast to the
Southern Plains.
