....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE LOWER
MISSISSIPPI VALLEY...

....SUMMARY...
A few strong thunderstorms could occur across the Lower Mississippi
Valley on Friday.

....Southeast Texas to Lower Mississippi Valley...
Linearly organized thunderstorms are expected to be ongoing Friday
morning, near/east of the Mississippi River around daybreak,
potentially including western Tennessee south-southwestward across
Mississippi into Louisiana. Some strong to locally severe storms
could occur early in the day, perhaps mainly across Mississippi
where a modest reservoir of instability may reside coincident with a
deep-layer/low-level wind field that will remain strong during the
day, even while the main upper system quickly shifts away from the
region. Some air mass recovery is possible during the day on the
south-southwest periphery of the early day storms across the
ArkLaMiss.

Thunderstorms may increase in a northward-expanding trend Friday
night across southeast Texas toward the ArkLaMiss, as the low-level
baroclinic zone begins to return northward and isentropic ascent
increases. Some hail potential cannot be ruled out in the presence
of moderate elevated buoyancy and around 35-40 kt of shear within
the cloud-bearing layer.
