A cold front over parts of the Northern/Central Plains will become
quasi-stationary by Monday. The front will produce showers and severe
thunderstorms over parts of Central Plains. Therefore, the SPC has issued
an Enhanced Risk (level 3/5) of severe thunderstorms over the Central
Plains through Monday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts,
hail, and a few tornadoes. In addition, there is a threat of severe
thunderstorm wind gust, of 65 knots or greater over parts of the
Central/Southern High Plains. Moreover, there will be an area of hail, two
inches or greater, over parts of the Northern Plains and Central/Southern
High Plains.
Moreover, showers and thunderstorms will develop over parts of the
Upper/Middle Mississippi Valley and Northern/Central Plains, creating
heavy rain. Therefore, the WPC has issued a Slight Risk (level 2/4) of
excessive rainfall over parts of the Upper/Middle Mississippi Valley and
Northern/Central 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.
Additionally, showers and thunderstorms will develop over parts of the
Southern Plains, creating heavy rain. 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.
On Monday, the threat of severe thunderstorms moves east of the dryline as
upper-level energy moves over the Southern Plains/Lower Mississippi
Valley. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe
thunderstorms over the Southern Plains/Lower Mississippi Valley from
Monday through Tuesday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts,
hail, and a few tornadoes.
Moreover, the energy that produces the showers and thunderstorms will
cause heavy rain over the Middle/Lower Mississippi Valley and Southern
Plains. Therefore, the WPC has issued a Slight Risk (level 2/4) of
excessive rainfall over parts of the Middle/Lower Mississippi Valley and
Southern Plains from Monday through Tuesday 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.
On Tuesday, the threat of severe thunderstorms will decrease slightly over
the Upper/Middle Mississippi Valley and Central Plains. Therefore, there
will be a Moderate Risk of severe thunderstorms over the area.
However, the threat of excessive rainfall will continue over the
Upper/Middle/Lower Mississippi Valley and Central/Southern Plains.
Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive
rainfall over parts of the Upper/Middle/Lower Mississippi Valley and
Central/Southern Plains on Tuesday. 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.
Meanwhile, onshore flow and a steady stream of upper-level energy over
the Pacific Northwest will trigger rain and snow melt over parts of the
Pacific Northwest into the Northern Intermountain Region from Sunday into
Monday. Therefore, the WPC has issued a Slight Risk (level 2/4) of
excessive rainfall over parts of the Pacific Northwest 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.
Additionally, the heavy rain and snow melt will develop over parts of the
Northern Intermountain Region. Therefore, the WPC has issued a Slight Risk
(level 2/4) of excessive rainfall over parts of the Northern Intermountain
Region 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.
Moreover, heavy rain and snow melt will develop over parts of the Northern
Intermountain Region on Monday. Therefore, the WPC has issued a Slight
Risk (level 2/4) of excessive rainfall over parts of the Northern
Intermountain Region from Monday into Tuesday 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.
Furthermore, a developing upper-level ridging will build over California
and continue over southern/western Texas, aiding in spawning Heat
Advisories over western/southern Texas and Central California.
