…There is a Slight Risk of excessive rainfall over parts of the Southern
High Plains/Southern Rockies and Eastern Gulf Coast on Thursday and
Northern Plains/Upper Mississippi Valley on Friday…
…There is a Slight Risk (level 2/5) of severe thunderstorms over parts
of the Northern Plains and parts of the Northeast and northern
Mid-Atlantic on Thursday…
On Thursday, a front along the Southeast Coast and Central Gulf Coast will
linger through Friday morning before dissipating on the 4th of July.
Tropical moisture over Florida and upper-level energy will trigger showers
and thunderstorms with heavy rain over parts of the western coast of the
Florida Peninsula. Therefore, the WPC has issued a Slight Risk (level
2/4) of excessive rainfall over parts of the Eastern Gulf Coast through
Friday 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.
In addition, moisture streaming northwestward over the Southern Plains
will produce showers and thunderstorms with heavy rain over parts of the
Southern High Plains/Southern Rockies. Therefore, the WPC has issued a
Slight Risk (level 2/4) of excessive rainfall over parts of the Southern
High Plains/Southern Rockies through Friday 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 second front over the Northern Rockies/Northern
Intermountain Region and into parts of the Pacific Northwest will move
eastward, the Northern High Plains to the Northern Rockies and into the
Northern Intermountain Region by late Thursday night. The front will
produce showers and severe thunderstorms over parts of the Northern Plains
Thursday evening into Friday morning. Therefore, the SPC has issued a
Slight Risk (level 2/5) of severe thunderstorms over parts of the Northern
Plains through Friday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts,
hail, and a few tornadoes. There will be an added threat of hail two
inches or greater over the area.
Moreover, a front extending from the Great Lakes to the Northern Plains
will move eastward off the Northeast Coast by Friday morning. On Thursday,
the front will trigger showers and severe thunderstorms over parts of the
Northeast and northern Mid-Atlantic. Therefore, the SPC has issued a
Slight Risk (level 2/5) of severe thunderstorms over parts of the
Northeast and the northern Mid-Atlantic through Friday morning. The
hazards associated with these thunderstorms are frequent lightning, severe
thunderstorm wind gusts, hail, and a minimal threat of tornadoes.
Additionally, on Thursday, upper-level energy, daytime heating, and
moisture will develop showers and thunderstorms over parts of the Pacific
Northwest, Northern Intermountain Region, Northern Rockies, and Great
Basin.
Meanwhile, on the 4th of July, as the front over the Northern High Plains
moves across the Northern Plains into the Upper Mississippi Valley, strong
to severe thunderstorms will develop over parts of the Northern/Central
Plains and Upper Mississippi Valley. The showers and thunderstorms will
produce heavy rain over parts of the Northern Plains/Upper Mississippi
Valley. Therefore, the WPC has issued a Slight Risk (level 2/4) of
excessive rainfall over parts of the Northern Plains/Upper Mississippi
Valley from Friday through Saturday 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.
Also on the 4th of July, showers and thunderstorms will develop over parts
of the Pacific Northwest, Northern California, Northern Rockies, and the
Northern Intermountain Region/Great Basin. Further, upper-level energy and
ample moisture will trigger showers and thunderstorms over parts of the
Central/Southern Rockies and Central/Southern Plains on Friday.
Furthermore, upper-level energy and ample moisture will create showers and
thunderstorms over parts of the Central Gulf Coast, Tennessee Valley,
Southeast, Central/Southern Appalachians, and southern Mid-Atlantic on the
4th of July.
