...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR SOUTHERN
LOUISIANA...

...SUMMARY...
A tornado is possible over southern Louisiana Thursday night.

...Central Gulf Coast...
Hurricane Delta is forecast to move north over the west-central Gulf
of Mexico on Thursday and Thursday night and approach the Louisiana
coast according to the National Hurricane Center's latest forecast. 
A maritime tropical airmass will gradually infiltrate the coastal
parishes of Louisiana during the day and the I-10 corridor during
the evening and overnight.  Within the outer northeastern envelope
of Hurricane Delta, low-level flow is forecast to intensify across
southern Louisiana with enlarged hodographs.  As low-level moisture
increases and surface dewpoints rise into the lower-mid 70s F, the
development of 200-800 J/kg MLCAPE is possible across southern
Louisiana.  A few of the stronger updrafts located in the outer
bands of Delta may yield intermittent storm-scale rotation and a
possible tornado risk, mainly late Thursday night into early Friday
morning.

Elsewhere, generally tranquil conditions will occur across much of
the contiguous United States.
