Areas affected...southwest MS vicinity

Concerning...Severe potential...Watch unlikely=20

Valid 270705Z - 270800Z

Probability of Watch Issuance...20 percent

SUMMARY...Potential for a tornado or two may linger in the southwest
Mississippi vicinity for a few more hours. This potential is
expected to remain too conditional/short-lived for a watch issuance.

DISCUSSION...Arcing band of convection had largely weakened last
hour with notable warming in IR cloud tops. Still, the environment
conditionally supports supercell development through about 09-10Z.
The potential for a tornado or two will be most prominent along the
northern edge of the mid 60s surface dewpoint plume, which has its
apex up the Lower MS Valley. This northern extent of surface-based
instability is not expected to expand much farther north during the
pre-dawn hours. In addition, hodograph curvature will gradually
diminish as strong low-level flow becomes further displaced from the
lingering convective arc.
