...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM
CENTRAL/EAST TEXAS TO THE LOWER MISSISSIPPI VALLEY AND TENNESSEE
VALLEY...
...SUMMARY...
Widespread strong thunderstorm development is expected from parts of
central and eastern Texas to the lower Mississippi and Tennessee
Valleys, and into the Cumberland Plateau by evening. This includes
potential for large hail and damaging wind gusts.
...Southern Plains to Lower Mississippi Valley/Tennessee Valley...
A residual MCS, with diminished intensity since early on the
overnight, persists at daybreak along the Red River and
Texas/Oklahoma border region eastward into the Mid-South largely
paralleling I-40, with a probable related MCV across eastern
Oklahoma. A relatively isolated severe potential will initially
exist with these storms this morning. However, an intensification of related/downstream storms is expected by midday, potentially
spanning parts of Arkansas into western/Middle Tennessee, western
Kentucky, and northern Alabama. Additional severe storm development
will be possible this afternoon northeastward into the middle Ohio
Valley and toward the Cumberland Plateau, as increasing
low-level/deep-layer southwesterly winds overlie a moderately
unstable boundary layer. Multiple organizing storm clusters can be
expected regionally this afternoon into evening.
Farther southwest across central/eastern Texas, while considerable
drying and stabilization is still apparent in observational data
after last evening's MCS, the air mass should steadily recover with
moistening and relatively aggressive destabilization into peak
heating. Initial thunderstorm development will be accompanied by the
potential for large hail, with supercells capable of very large hail
possible especially with west-southwestward extent into the Edwards
Plateau and toward the Rio Grande. Damaging wind potential will also
increase as convection organizes and spreads southeastward into this
evening across central/southeast Texas, and possibly Deep South
Texas tonight.
