.DISCUSSION...
Issued at 1201 AM CDT Mon Sep 8 2025
The frontal boundary is currently well offshore. However, latest
observations still show PW values up to 2.2 inches over the
region. Therefore, lingering showers with a few thunderstorms are
expected overnight, particularly along the coast and over the
waters. Per water vapor satellite imagery and surface observations
(temps and dewpoints), a drier airmass is starting to filter in
from the northeast. This will result in decreasing cloud cover
from north to south and lower humidity (dewpoints), especially for
areas further inland today. This will lead to a comfortable early
morning with lows in the low 60s to low 70s. This pattern of
comfortable nights will continue through at least Thursday. While
it will remain warm during the day; expect comfortable nights as
temperatures drop into the 50s and low 70s (closer to the coast).
Beyond Thursday, a ridge of high pressure will strengthen over
the Plains and slowly expand eastward over the weekend. This
pattern will keep rain chances low, but will result in warmer
conditions. Highs are expected to climb into the mid 90s.
Precipitation-wise, little to no rain is anticipated through most
of the week. The only exception will be isolated activity along
the coast where the frontal boundary is expected to stall,
creating a focus for better moisture convergence.

VFR and NE winds throughout - 5-10 knots today, becoming light
after sunset. There is a deck of clouds around 070 moving through
the area that has merited some mentions in the TAFs, but will very
safely stay VFR despite that.

.MARINE...
Issued at 1201 AM CDT Mon Sep 8 2025
The frontal boundary responsible of bringing showers is currently
extending well-offshore. With ample moisture, scattered showers
with a few thunderstorms are expected to persist overnight. Drier
air from the northeast will filter in today, reducing the chances
of rain. This boundary will stall along the northwestern Gulf
through most of the week, becoming a focal point for isolated
rain/storms along the Upper TX coast. Light to occasionally
moderate northeast to east winds will prevail through most of the
week. With a moderate pressure gradient along the front, winds
around 15 to 20 knots and seas up to 5ft are possible today. Winds
will remain light to occasionally moderate before shifting to the
southeast next weekend. Seas will generally stay low for the
majority of the week.
