Valid 12Z Sun Jun 09 2024 – 12Z Tue Jun 11 2024…There is a Moderate Risk of excessive rainfall over parts of the Middle
Mississippi Valley on Sunday……There is a Slight Risk of severe thunderstorms over parts of the
Northern/Central High Plains on Monday……There are Heat Advisories over parts of western Texas…
A front extending from the Mid-Atlantic southwestward to the Tennessee
Valley and then westward to the Central Rockies will move eastward to off
most of the Eastern Seaboard by Monday evening. Moisture pooling along the
boundary will aid in creating showers and thunderstorms with heavy rain
over southern Missouri. Therefore, the WPC has issued a Moderate Risk
(level 3/4) of excessive rainfall over parts of the Middle Mississippi
Valley through Monday morning. The associated heavy rain will create
numerous areas of flash flooding. Furthermore, many streams may flood,
potentially affecting larger rivers.Moreover, showers and strong to severe thunderstorms will develop along
the front from the Southeast to the Northern Intermountain Region.
Therefore, the SPC has issued a Marginal Risk (level 1/5) of severe
thunderstorms over parts of the Southeast, Tennessee Valley, lower
Mississippi Valley, Southern Plains, Central Rockies, and the Northern
Intermountain Region through Monday morning. The hazards associated with
these thunderstorms are frequent lightning, severe thunderstorm wind
gusts, hail, and a minimal threat of tornadoes.Meanwhile, a front over the Eastern Pacific will move inland to the
Pacific Northwest/Central California by early Sunday afternoon. On Sunday,
the boundary will produce showers and thunderstorms over parts of the
Pacific Northwest and Northern Intermountain Region. The front will
continue to move eastward to the Northern Plains by Monday. The front will
trigger showers and severe thunderstorms over parts of western South
Dakota, northwestern Nebraska, and extreme eastern Montana/Wyoming.
Therefore, the SPC has issued a Slight Risk (level 2/5) of severe
thunderstorms over parts of the Northern/Central High Plains from Monday
through Tuesday morning. The hazards associated with these thunderstorms
are frequent lightning, severe thunderstorm wind gusts, hail, and a few
tornadoes.Further, the showers and thunderstorms will also cause heavy rain to
develop over parts of the Northern Plains/Upper Mississippi Valley.
Therefore, the WPC has issued a Marginal Risk (level 1/4) of excessive
rainfall over parts of the Northern Plains/Upper Mississippi Valley from
Monday through Tuesday morning. In addition, the associated heavy rain
will create localized areas of flash flooding, affecting areas that
experience rapid runoff with heavy rain.Furthermore, along the front over the Southern High Plains, showers and
thunderstorms will cause heavy rain to develop over parts of the region.
Therefore, the WPC has issued a Marginal Risk (level 1/4) of excessive
rainfall over parts of the Southern High Plains from Monday through
Tuesday morning. In addition, the associated heavy rain will create
localized areas of flash flooding, affecting areas that experience rapid
runoff with heavy rain.Elsewhere, tropical moisture and upper-level impulses will aid in
producing showers and thunderstorms with heavy rain over parts of southern
Florida. Therefore, the WPC has issued a Marginal Risk (level 1/4) of
excessive rainfall over parts of southern Florida from Monday through
Tuesday morning. In addition, the associated heavy rain will create
localized areas of flash flooding, affecting areas that experience rapid
runoff with heavy rain.Moreover, upper-level energy over the Great Lakes/Northeast will help
produce rain over parts of the Great Lakes and the Northeast through
Monday night. Furthermore, upper-level ridging over Texas helps spawn Heat
Advisories over parts of western Texas.
