Area Forecast Discussion
National Weather Service New Orleans LA
256 PM CDT Sat Sep 14 2019

.SHORT TERM...
A westward moving upper low will traverse the Gulf the next couple
of days resulting in enhanced chances for convection across the
coastal waters and adjacent near coastal land areas. Otherwise,
generally dry conditions will prevail for much of the forecast
area. NHC does indicate a low end chance of tropical development
over the northwest Gulf primarily beyond 48 hours in association
with this feature. Any such eventual development would not have
any significant impact on the local forecast area. Temperatures
will continue to run above normal. 11

.LONG TERM...
Mid and upper level ridging will dominate the central Gulf Coast
region through the upcoming week resulting in a continuation of
above normal temperatures and below normal rain chances. High
temperatures in the mid and upper 90s will be possible on
multiple days. Some weakening of the ridge may occur next weekend.

&&

.AVIATION...
VFR category conditions will generally prevail at the terminals
through the TAF forecast period. An isolated shower or
thunderstorm could impact KHUM. 11

&&

.MARINE...
A tight pressure gradient across the northern Gulf will result in
in enhanced easterly flow across the coastal waters through
Sunday. Exercise caution headlines will be highlighted tonight
for most of the open waters and this may need to be extended into
Sunday. Shower and thunderstorm chances will also be enhanced the
next couple of days as a westward moving upper low traverses the
Gulf. Thereafter, light and occasionally variable winds will
prevail across the coastal waters as a ridge of high pressure
dominates the area. Easterly winds will likely increase again at
the end of next week as the pressure gradient tightens up again.
