.KEY MESSAGES...
- Surface high pressure will allow for dry conditions with cooler
  than normal night time lows tonight.
- Temperatures will warm Wednesday and the latter part of the

  become more from the east and southeast.
- An upper level high will build over the region late in the week
  into the weekend keeping rain chances out of the forecast.

.SHORT TERM...
(Tonight through Thursday night)
Issued at 1235 PM CDT Tue Sep 9 2025
Seeing a bit of a cu build up just east of the Atchafalaya Basin
as easterly low level flow tries to bring in some higher moisture.
This higher moisture may clip along the coast through Wednesday
afternoon and this will be the only locations that may see an
outside chance of a shower or storm.
Otherwise, mainly dry continental air will be maintained over the
forecast area. This will bring some cooler temperatures slightly
below climo norm again tonight. Then the air mass will slowly
modify with near climo norms each day and night for air
temperatures. Humidity values will remain low that will keep
afternoon heat at bearable levels.

.LONG TERM...
(Friday through next Monday)
Issued at 1230 PM CDT Tue Sep 9 2025
Good consensus in an upper level ridge building over the region
for the end of the week into the weekend. The dry and subsident
air aloft will keep a lid on convection and no significant shower
activity is expected.
As the dry air mass modifies and low level flow becomes a bit more
southeasterly, expect air temperatures to be on the warm side and
more summer-like. However, with some mixing of the dry air above
the surface during max heating, heat index will be kept in check
and near a just a little above the air temperature during the
period.

Issued at 619 PM CDT Tue Sep 9 2025
VFR conditions to persist past the end of the forecast period
thanks to a dry airmass in the region. There are isolated showers
across SELA, however most of this activity is expected to taper as
it moves west of the Atchafalaya.

.MARINE...
Issued at 1226 PM CDT Tue Sep 9 2025
Surface high ridging down from the northeast with a stalled
frontal boundary and lower pressure over the middle Gulf.
Interaction between these features will allow for a light to modest
easterly flow for the remainder of the week along with light to
modest seas. A scattered showers or storms will be possible into
Wednesday as a disturbance moves along the front, otherwise a dry
airmass aloft will help keep significant shower activity out of
the forecast for Thursday until the end of the period.
&&
.FIRE WEATHER...
Issued at 1222 PM CDT Tue Sep 9 2025
A dry airmass will settle over the region during the period. This
will bring little to no chance for significant rain and lower than
normal humidity. Afternoon minimum relative humidity values will
be below 50 percent on Wednesday, and below 40 percent for
Thursday and Friday.
