…There is an Enhanced Risk of severe thunderstorms over parts of the
Central/Southern High Plains on Saturday and over parts of the Central
High Plains on Sunday…
…There is a Moderate Risk of excessive rainfall over parts of the
Central Gulf Coast on Saturday…
…There is a Slight Risk of excessive rainfall over parts of the Pacific
Northwest, Northern Intermountain Region, Upper/Middle Mississippi Valley,
and Northern/Central Plains on Sunday and the Northern Intermountain
Region on Monday…
…There are Heat Advisories over western Texas…
Moisture streaming northward over the Plains and a dryline over western
Texas will aid in creating showers and severe thunderstorms over parts of
the Central/Southern High Plains. Therefore, through Sunday morning, the
SPC has issued an Enhanced Risk (level 3/5) of severe thunderstorms over
the Central/Southern High Plains. 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 and hail, two inches or
greater over parts of the Central/Southern High Plains. Moreover, there is
a second area of hail, two inches or greater, over parts of western Texas
and southeastern New Mexico.
Further, upper-level energy will aid in producing showers and severe
thunderstorms over parts of the Western Gulf Coast. Therefore, the SPC has
issued a Slight Risk (level 2/5) of severe thunderstorms over the Western
Gulf Coast through Sunday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts,
hail, and a few tornadoes.
Moreover, showers and thunderstorms will develop over parts of the Central
Gulf Coast, creating heavy rain. Therefore, the WPC has issued a Slight
Risk (level 2/4) of excessive rainfall over parts of the Central Gulf
Coast 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 the most vulnerable.
Additionally, showers and thunderstorms will develop over parts of the
Central/Southern High Plains, creating heavy rain. Therefore, the WPC has
issued a Slight Risk (level 2/4) of excessive rainfall over parts of the
Central/Southern High Plains 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 the most vulnerable.
On Sunday, a cold front extending from the Northern Plains to the Great
Basin will move eastward to the Upper/Middle Mississippi Valley by Monday,
producing showers and severe thunderstorms over parts of the Central High
Plains. Therefore, the SPC has issued an Enhanced Risk (level 3/5) of
severe thunderstorms over the Central High Plains from Sunday 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.
Moreover, a second area of severe thunderstorms will also occur over the
Southern High Plains on Sunday. Therefore, the SPC has issued a Slight
Risk (level 2/5) of severe thunderstorms over the Southern High Plains
from Sunday through Monday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts,
hail, and a few tornadoes.
Furthermore, showers and thunderstorms will cause heavy rain over the
Upper/Middle Mississippi Valley and Northern/Central Plains. 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
from 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 the most vulnerable.
On Monday, the threat of severe thunderstorms and excessive rainfall will
decrease slightly over the Middle/Mississippi Valley and Central/Southern
Plains. Therefore, there will be a Moderate Risk of severe thunderstorms
and excessive rainfall over the area.
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 early
Saturday into Monday. On Sunday the rainfall will increase, therefore, the
WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts
of the Pacific Northwest from 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 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 from 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 the most vulnerable.
Moreover, on Monday, the rain and snow melt will produce heavy rain 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 on Monday. 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 over southern Texas will aid
in spawning Heat Advisories over Western Texas.
