(Tonight through Friday night)
Issued at 308 PM CDT Wed Sep 18 2024

Away from the very isolated few showers in Lower Acadiana, it`s
calm, quiet and hot. High pressure developing overtop east Texas
has brought about slightly warmer and drier conditions today, and
as the high continues expanding overhead, this trend will continue
to the end of the work week.

Temperatures have warmed into the upper 80s to low 90s today which
is only 1 to 2 degrees above climatological normal. The warming
trend will continue Thursday and Friday with area wide low 90s
expected each day.

.LONG TERM...
(Saturday through next Tuesday)
Issued at 308 PM CDT Wed Sep 18 2024

The long range portion of the forecast remains essentially unchanged
from yesterday with our mostly dry and mainly warm pattern
continuing. A mid/upper-level ridge initially extending from Old
Mexico through cntl/ern TX into the Mid-South is progged to
gradually shift ewd across the forecast area in response to a trof
digging ewd past the Rockies. Meanwhile, sfc ridging initially
centered over the East Coast will gradually shift ewd, maintaining
an onshore low-level flow. The result will be dry and warm
conditions continuing through the weekend. By the time we get into
next Tuesday, model solutions indicate the trof will have shifted
ewd enough to break down the ridge and allow for the capping to
cease enough for the potential for a few showers/storms on
Tuesday/Wednesday.

Highs Friday/Saturday look to run in the lower 90s as ridging reigns
supreme before a slow drop back into the upper 80s by Tuesday with
the onset of better moisture/cloud cover.

Light winds and VFR CIGS will prevail throughout the forecast

round of patchy fog is expected to develop area-wide. Fog will
burn off quickly post-sunrise.

.MARINE...
Issued at 308 PM CDT Wed Sep 18 2024

Expect dry, calm conditions as well as low winds and seas to
prevail through the end of the work week as high pressure ridges
in overhead. The pressure gradient tightens late into the weekend
as an upper disturbance nears the region. This should result in a
gradual increase of winds and seas by Sunday.
