.SHORT TERM...
(This evening through Friday night)
Issued at 323 PM CDT Thu Sep 19 2024

All is quiet for the short term as the upper level ridge tries to
push east. While we do see some isolated showers out there, mainly
along the MS Coast, a lack of any deep layer moisture will
prevent anything further than a shower or two. PWs on this
morning`s 12z sounding were ~1.60" showing that moisture continues
to very gradually go down.

Into tomorrow we will see much of the same as the ridge continues
to try to push eastward further into our area. We likely see even
less shower activity tomorrow afternoon than we saw today. Did
adjust temperatures a tad, on par with the NBM50, to bring them
up a touch closer to model guidance. The low to mid 90s are likely
for the majority of the area tomorrow.

.LONG TERM...
(Saturday through Wednesday night)
Issued at 323 PM CDT Thu Sep 19 2024

Upper level ridging drapes across Texas and coming into Louisiana
will drift eastward early next week as a trough deepens from the
Great Lakes. There is uncertainty with specifics on the trough with
guidance though. But for the most part weak sfc high will keep PoPs
relatively low with the best chances at the end of the week around
20-30%ish.  Temperatures remain near seasonable in the upper 80s/low
90s with lows in the low 70s.

For the tropics, there is decent agreement on something forming in
the Caribbean somewhere in the 7-10 day range, but since there`s no
circulation for models to track on. The track will depend on a few
things, but primarily where exactly the circulation forms and the
aforementioned trough. Don`t get too caught up in specific runs or
models as there will still be a lot of uncertainty at this point of
the forecast.

.AVIATION...
(00Z TAFS)
Issued at 618 PM CDT Thu Sep 19 2024

Isolated convection continued at forecast issuance time, but is
not expected to impact any forecast terminals in the near term.
Little to no convection is expected on Friday, and will not carry
in any terminals. Low end threat of reduced visibilities around
sunrise Friday, but not high enough to justify mentioning in
forecast at this time.

.MARINE...
Issued at 323 PM CDT Thu Sep 19 2024

Light wind and calm seas will remain in place over the next couple
days as high pressure remains centered over the waters. As this
system drifts inland over the weekend, we will see a more
established easterly flow around 10-15kts. This will bring seas up
to 2-3ft later into the weekend.
