...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE CENTRAL GULF COAST...
...SUMMARY...
A marginal tornado threat may continue for another hour or two
across parts of the central Gulf Coast.
...Central Gulf Coast...
A shortwave trough is evident on water vapor over the mid
Mississippi Valley. This feature will move northeastward into the
Ohio Valley this evening. At the surface, a moist airmass will
remain in the central Gulf Coast states. Scattered thunderstorms are
ongoing within the moist airmass from far southeast Louisiana into
southwest Alabama. Most of the airmass is weakly unstable. However,
the southern edge of a mid-level jet is located in the central Gulf
Coast region, which is creating moderate deep-layer shear. This,
combined with backed southeasterly flow at the surface and veering
winds with height, could be enough for a marginal tornado threat
over the next hour or two with supercells that persist. The severe
threat is expected to diminish as instability drops across the
region.
