.SHORT TERM...
(This evening through Tuesday night)
Issued at 140 PM CDT Mon Oct 21 2024
Dry high pressure will remain planted across the area,
suppressing rain chances and keeping relative humidity seasonably
pleasant. Low dewpoints and clear skies will allow overnight lows
to fall into the low to mid 50s north and into the mid 50s to
lower 60s south, while afternoon highs will rebound into the low
to mid 80s.

.LONG TERM...
(Wednesday through Sunday night)
Issued at 140 PM CDT Mon Oct 21 2024
A gradual warming trend will continue into the latter part of the
work week. Expect afternoon highs to be in the mid to upper 80s
by Wednesday, which is 10-15 degrees higher than normal for this
time of year. The good news is highs look to level out at that
point with no additional warming. Can't rule out a few places
hitting 90 degrees, especially Thursday afternoon when many
locations along/north of a line from roughly New Iberia to Hammond
to Poplarville have a 10-20% chance of reaching 90 degrees. It's
a low chance, but one worth mentioning given how late in the year
it's getting. 90 degrees has only been observed a handful of
times after mid October, with our normal last 90 degree day
occurring in late September.
A weak boundary looks likely to sink toward the area over the
weekend, but there are questions regarding whether it will make it
to the coast. Even if the boundary makes it through the local
area, a lack of moisture will preclude any significant rain
chances and there is little to no air mass change. All in all,
temperatures may drop a few degrees over the weekend, but
otherwise, no appreciable changes to the sensible weather,
regardless of if the front clears the area.

.AVIATION...
(18Z TAFS)
Issued at 140 PM CDT Mon Oct 21 2024
VFR conditions will prevail through the period. Under the
influence of high pressure, winds will remain light with little to
no cloud cover.
&&
.MARINE...
Issued at 140 PM CDT Mon Oct 21 2024
Benign conditions will persist across the coastal waters through
the period as high pressure dominates the area. Winds will
continue to ease and should generally be below 10 knots by
tomorrow, remain below 10 knots through the remainder of the work
week. Wind direction should be generally E to NE, but will be
variable at times due to the weak gradient.
