.UPDATE...
Issued at 943 PM CDT Fri Sep 20 2024

Isolated convection earlier this evening over extreme lower
portions of southeast Louisiana coastal parishes has dissipated.
Updated ZFP to remove the afternoon portion of the the forecast
and remove temporal wording from the overnight period.

.SHORT TERM...
(This evening through Saturday night)
Issued at 216 PM CDT Fri Sep 20 2024

All is quiet for the short term period as upper level ridging
continue to build into the area from the west. This has kept
little to no convection from forming today, outside of a few
showers offshore. This will continue tomorrow with PoPs ~0% as the
ridge moves further overhead.

On the other side of things, the ridge continuing to build in
also helps temperatures rise just a bit. Adjusted tomorrow`s
MaxT`s using a blend of the 50th and 75th percentile to get them
closer to guidance. High temperatures tomorrow afternoon will be
in the low to mid 90s for all. HRL

.LONG TERM...
(Sunday through Thursday night)
Issued at 216 PM CDT Fri Sep 20 2024

At the beginning of the extended period we will be under upper level
ridging anchored to our west.  As the week progresses the high
pressure stays in place but blends with the Bahama high.  The result
of this setup is dry, warm weather.  By mid-week, we see a trough
moving off the Rockies and as it moves eastward provides a path for
Gulf moisture to move into the area bringing PoPs up into
general/typical summertime ranges of 20-30% through the end of the
period. Temperatures will also drop slightly as the week
progresses.

.AVIATION...
(06Z TAFS)
Issued at 1137 PM CDT Fri Sep 20 2024

Mainly VFR conditions at 05z, although there may be some
occasional minor visibility restrictions at KHUM. Any issues
around sunrise are expected to remain isolated. Could be a bit of
late night cirrus at KGPT, as there is a patch of clouds over
northern Mississippi that could track near or just east of coastal
Mississippi. During the day on Saturday, with forecast
precipitable water values in the 1.1 to 1.3 inch range, don`t
anticipate any more than scattered cumulus clouds for much of the
area.

.MARINE...
Issued at 216 PM CDT Fri Sep 20 2024

Winds hold calm through early tomorrow, then we will see a more
steady easterly flow setup around ~10-15kts. This will bring an
increase in seas, ~2-3ft, through the later part of the weekend
and into early next week. These conditions will stick around for
the next several days.
