.SHORT TERM...
(Today through Saturday night)
Issued at 1159 AM CDT Thu Sep 4 2025

After a waterspout along the Cameron coast this
morning, lingering convection continues to work its way offshore
this afternoon with slightly drier air slowly advecting into central
Louisiana. Expect dewpoints to fall into the upper 60s to lower 70s
through the afternoon. Seasonable temperatures along with somewhat
drier air will continue across the region through late Friday.
Moisture will begin pooling both at the surface and aloft head of
another frontal boundary expected to push through the region Sunday.
This will allow dewpoints to climb back into the mid 70s along with
scattered afternoon convection Saturday.

.LONG TERM...
(Sunday through Thursday)
Issued at 1159 AM CDT Thu Sep 4 2025

A frontal boundary will push through the region Sunday
marked primarily by a wind shift to the north that will advect some
noticeably drier and slightly cooler air into the region through
the first half of next week. NBM guidance depicts dewpoints
falling into the 50`s Monday and Tuesday allowing overnight lows
to fall into the low to mid 60s. Meanwhile, afternoon highs will
peak in the upper 80s. Upper level ridging over northern Texas
will continue to stream dry air across the gulf coast through most
of next week maintaining mostly clear skies with comfortable
dewpoints each afternoon as the air mixes down to the surface.

.MARINE...
Issued at 1159 AM CDT Thu Sep 4 2025

Weak high pressure across the northern Gulf will allow for
mainly light southerly winds and low seas for the remainder of the
week. A few thunderstorms will continue across the coastal waters
this afternoon in the vicinity of a weak boundary. These should
dissipate this evening with no precipitation expected Friday.
Chances for showers and thunderstorms will increase over the
weekend into early next week as a frontal system moves into the
coastal waters. Light offshore flow will develop by Sunday behind
the front, with the offshore winds increasing early next week as
high pressure builds down from the Midwest.

.FIRE WEATHER...
Issued at 1159 AM CDT Thu Sep 4 2025

Slightly drier air will continue to work into the
region this afternoon behind a weak boundary. Dewpoints will fall
into the upper 60s to lower 70s with minimum RH values this
afternoon ranging from 40-50%. Humidity will increase Saturday ahead
of a frontal boundary that will push through the region Sunday. This
will produce scattered thunderstorms Saturday afternoon.
Noticeably drier air will filter into the region early next week
with minimum RH values falling as low as 30% during the afternoon.
