.DISCUSSION...
Issued at 1236 PM CDT Thu Sep 24 2026

The weak boundary we have been talking about is in the area, but
rather diffuse. From wind observations, it`s likely just south of
the Houston metro area, but the lower dewpoints (not much lower)
are farther north toward Lufkin. Temperatures mid-day are
currently running an average of 2-4 degrees cooler than this time
yesterday, so at least there`s a small improvement! That though
with the dewpoints being slightly lower, more efficient warming
could still occur this afternoon and bring those temps right back
up to near yesterday. A few (very few) showers have been
developing south of the front, generally south of a line from
Freeport to Victoria. This will continue this afternoon, but
likely continue to drift farther south and out of our area.

As the briefly drier air continues to drift in tonight, we will
expect to see some cooler low temperatures across the area
tonight. Some outlying locations could drop into the upper 60s,
but will likely not see that for the city. Climo note: IAH has not
had a low temperature below 70 since May 28th. I dont think it
happens tonight, but it may not be too far away! (more on that in
a moment.) Similar conditions should persist through Friday into
Saturday with the slightly cooler temps - low to mid 90s for
highs and upper 60s to lower 70s for lows before moisture starts
to return with onshore flow later in the weekend.

Moving into next week we`ll be watching a pattern change with the
ridge that has been in place over us shifting south and weakening
a bit. A few things we`ll be keeping an eye on...Pacific moisture
in the mid-levels, Gulf moisture in the low levels, and a trough
progressing eastward from the Pacific. There are differences in
timing of especially the Pacific moisture and trough between
models, and this phasing will be key to how much deep moisture we
get moving toward Texas by mid-week, but the hope is that we can
get some increased rain chances in here by mid-week ahead of a
cold front. GFS ensembles have been more consistent and wetter for
our area while ECMWF has trended toward a the trough weakening as
it approaches and a drier solution. So we wont get too specific
about the details this far out, but with average or slightly
higher than average confidence, have medium to maybe high rain
chances Tuesday into Wednesday followed by the first actually
noticeable cold front of the season with temps at least back to
around normal. Stay tuned.

.AVIATION...
(18Z TAF Issuance)
Issued at 1236 PM CDT Thu Sep 24 2026

VFR conditions prevails across the area with predominantly ENE-NE
breeze. Increased dry air will reduce rain chances to be absent from
the TAFs. If any isol showers develop they will be confined to the
coast. The evening will bring relaxing winds to light and VRB.
Chances of BR and MVFR CIGs also remain low enough to out of the
TAFs due to that previously mentioned dry air. Tomorrows conditions
are anticipated to remain similar to today.

.MARINE...
Issued at 1236 PM CDT Thu Sep 24 2026

An isolated shower or storm will continue this afternoon mainly
around the Matagorda Bay area. Otherwise expect a moderate
northeasterly flow as a weak cold front sage through the region.
Weak to moderate east to northeast flow continues through early
Saturday before becoming more southeast through the early part of
next week with 2-3 foot seas. By mid-week we`ll could see an
increase to moderate to strong winds and would expect an
associated increase in seas.
