Southern Plains on Sunday…
…There is a Slight Risk of severe thunderstorms over parts of the
Southern High Plains on Saturday…
A slow-moving front extending from the Upper Great Lakes/Upper Mississippi
Valley southwestward to the Southern High Plains advances to the Lower
Great Lakes/Ohio Valley roughly southwestward to the Southern Plains by
Monday evening. Showers and thunderstorms will develop along the boundary
from the Upper Great Lakes/Upper Mississippi Valley to the Southern High
Plains. Rain will also develop over parts of the Central Rockies, with
some wet snow at the highest elevation. Further, upper-level energy will
aid in producing showers and thunderstorms over parts of the
Northeast/Mid-Atlantic and Central Appalachians, also on Saturday evening
into Sunday afternoon. Elsewhere, upper-level energy will trigger showers
and thunderstorms over parts of Florida.
The front over western Texas and eastern New Mexico will create showers
and severe thunderstorms over parts of the Southern High Plains.
Therefore, the SPC has issued a Slight Risk (level 2/5) of severe
thunderstorms over parts of the Southern High Plains through Sunday
morning. The hazards associated with these thunderstorms are frequent
lightning, severe thunderstorm wind gusts, hail, and a few tornadoes.
Moreover, there is an increased threat of hail, two inches or greater over
the area.
In addition, the showers and thunderstorms will produce heavy rain over
the Southern High Plains. Therefore, the WPC has issued a Slight Risk
(level 2/4) of excessive rainfall over parts of the 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, the threat of severe thunderstorms will decrease slightly.
Showers and strong to severe thunderstorms will develop over parts of the
Middle Mississippi Valley 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 from Sunday into
Monday morning. The hazards associated with these thunderstorms are
frequent lightning, severe thunderstorm wind gusts, hail, and a minimal
threat of tornadoes.
Moreover, heavy rain will be associated with the showers and thunderstorms
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 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.
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 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.
Overnight Sunday, weak onshore flow will create rain showers over parts of
the Pacific Northwest.
