Weather Wednesday April 10 2024 Heavy weather east Texas and most of the lower Mississippi Valley

The Weather Man Podcast, I talk about weather!

Heavy rain, flash flooding and severe weather threat will expand into
the central Gulf Coast States, Tennessee Valley and parts of the Southeast
on Wednesday, reaching into the Midwest, Ohio Valley and the East Coast by
Thursday.
Critical fire danger remains over the Texas Big Bend and Rio Grande
Valley through this evening.
A very active weather pattern is currently unfolding throughout much of
the southern Plains and lower Mississippi Valley as numerous showers and
thunderstorms impact the region, with several modes of hazardous weather
possible. Ample atmospheric moisture content, nearby frontal boundaries,
and a supportive upper level environment are expected to continue the
threat of severe weather and flash flooding over the next few days.
Through tonight, the bulk of the impactful weather is forecast to remain
across the southern Plains and lower Mississippi Valley, where many
locations have already been dealing with soaking rain and intense
thunderstorms over the last 12 hours or so. With more heavy rain on the
way, numerous instances of flash flooding are likely overnight from
east-central Texas to parts of western Mississippi. A Moderate Risk (level
3/4) of Excessive Rainfall remains in effect, as well as Flood Watches
extending from Texas to Alabama. Additionally, thunderstorms will be
capable of producing a few tornadoes, large to very large hail, and severe
wind gusts.
The disruptive weather is anticipated to expand eastward on Wednesday
throughout the central Gulf Coast States, Tennessee Valley, and Southeast.
Multiple rounds of strong thunderstorms could dump around 2 to 4 inches of
rainfall over a relatively short time period from northeast Louisiana to
southwest Georgia and the Florida Panhandle. This has prompted the
Moderate Risk of Excessive Rainfall to be extended into these regions on
Wednesday. A Moderate Risk (level 4/5) for severe thunderstorms also
exists on Wednesday from east-central Louisiana to southwest Mississippi,
where the potential exists for several tornadoes (a few of which could be
strong), and widespread damaging wind gusts. Residents and visitors are
advised to have multiple ways to receive warnings and never drive through
flooded roadways.
This storm system is forecast to become better organized by the latter
part of Wednesday and continue on a northeastward progression over the
lower Great Lakes by Thursday night. Showers and thunderstorms will shift
into the Ohio Valley, Southeast, and Mid-Atlantic, but should become more
progressive in nature. The greatest threat for damaging wind gusts
associated with strong thunderstorms on Thursday extends from the
Carolinas to northern Florida, as well as the Ohio Valley. Heavy rain may
also lead to scattered instances of flash flooding from the
southern/central Appalachians to the northern Mid-Atlantic. Lastly, strong
southerly flow along the East Coast could lead to gusty winds and coastal
hazards from the Southeast to the Mid-Atlantic on Thursday.
Mostly tranquil weather is forecast elsewhere throughout the Nation as
upper ridging builds over the Intermountain West. Rain and snow showers
are expected to swing from the Northwest to the northern High Plains
tonight as a frontal system quickly moves east and over the northern
Plains on Wednesday. Otherwise, gusty winds and low relative humidity will
continue to create Critical Fire Weather over the Texas Big Bend and Rio
Grande Valley into tonight, with Elevated Fire Weather continuing into
Wednesday.
