Areas affected...Southern Mississippi and southeast Louisiana

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

Valid 261247Z - 261415Z

Probability of Watch Issuance...20 percent

SUMMARY...An MCS will likely persist while approaching the coast by
mid morning. Isolated wind damage will be possible, but a watch
does not appear necessary.

DISCUSSION...An MCS is moving south-southeastward along the
low-level moisture/buoyancy gradient across southern MS and
southeast LA, supported by sufficient northwesterly deep-layer shear
to keep convection upright along the gust front. The MCS motion
toward the south-southeast at about 30 kt and velocity data from
KHDC suggest mostly 30-40 kt outflow gusts are probable, though
isolated tree damage may occur with the strongest gusts. Given only
weak low-level flow noted in regional VWPs, it appears unlikely that
these storms will intensify substantially this morning. Thus, a
watch does not appear necessary.
