...New AVIATION...

.KEY MESSAGES...

- A robust storm system will bring periods of moderate to heavy
  rainfall and strong to severe thunderstorms tonight through
  Sunday morning:

    - A Flood Watch in effect from midnight tonight until 4AM
      Sunday morning. Please read the hydrology discussion for
      more details.

    - Two rounds of rain and thunderstorms are expected, the first
      late tonight into Saturday morning and the second late
      Saturday afternoon through early Sunday morning.

    - Damaging wind gusts over 60 MPH are the primary concern.
      However, large hail and a few tornadoes cannot be ruled out.

- Moderate to strong onshore flow will lead to hazardous marine
  condition today through the weekend. In addition to gusty winds
  and elevated seas, there will also be a high risk of rip
  currents along area beaches and elevated tides.

- Much cooler weather expected by the second half of the week.

.DISCUSSION...
Issued at 957 PM CDT Fri Oct 24 2025

Writing this forecast discussion a few hours before I typically
would as the radar is expected to be quite active during the
normal time. As of 9pm, the MCS that we were expecting to
develop this evening has developed with a line of thunderstorms
along and east of I-35. This line of strong to severe
thunderstorms is expected to pass through the Brazos Valley
between 1-3am, along the I-45 corridor (including the Houston
Metro) between 3-5am, and off the coast/to the east between 5-8am
this morning. In addition to the thunderstorms along the line
itself, isolated discrete storms may pop up ahead of the line.
Heavy rainfall (with rates up to 2-3" per hour possible) and
damaging wind gusts over 60mph will be the greatest threats if
severe thunderstorms occur, but large hail and even an isolated
tornado will be possible. A Severe Thunderstorm Watch has already
been issued for portions of the Brazos Valley (Burleson, Brazos,
and Madison counties) through 3am CDT. Expansions and/or
extensions of this Watch, or an additional Watch for the rest of
SE Texas will be possible through the night.

We will likely enter a lull in the activity once this first round
of strong to severe thunderstorms exits to the east. It's
possible the the morning storms stabilizes us enough in its wake
that we see no activity during the afternoon, but some scattered
light to moderate showers or thunderstorms will be possible. As
the sun sets, out attention will once again be turning to the west
as yet another line of potentially strong to severe thunderstorms
develop. One difference of this line of storms compared to the
line of storms we are dealing with tonight is that it is expected
to form much closer to our region - along or east of I-35,
compared to tonight's storms initializing out in west Texas. This
will lead to more uncertainty on the strength and timing of this
second round of storms. The most likely scenario at this point is
that a line of thunderstorms will begin to form along the I-35
corridor around or shortly before sunset. It will then move
southeasterly through our region through the evening and exit off
the coast possibly as early as Midnight or as late 3-4am. Again,
all severe weather hazards will be possible.

A Flood Watch remains in effect across the the area through early
Sunday morning. Rainfall totals through the Sunday morning
(including tonight's storms, Saturday afternoon scattered
activity, and Saturday night's storms) will generally be up to
2-4", but isolated higher amounts of 4-6" will be possible. Minor
urban and small stream flooding will be the most likely impact,
however a few instances of flash flooding cannot be ruled out.
While the area remains very dry after an extended period of above
normal temperatures and near-zero rainfall, the intense rainfall
rates (possibly up to 2-3" per hour or higher) and possibility of
repeated heavy rainfall over the same area led to the issuance of
the Flood Watch. More info can be found in the Hydro section
below.

Expected drier, sunnier weather on Sunday with a gradual warming
trend through Tuesday. A more traditional cold front (one that will
actually bring us colder air) is expected to pass through SE Texas
midweek, likely sometime late Tuesday into Wednesday morning. It
may bring some isolated to scattered showers and storms with its
FROPA, but it's biggest impact as of now is the ushering in of
below normal temperatures. High temperatures beginning Wednesday
will generally be in the low to mid 70s (maybe not rising above
the upper 60s in the Piney Woods) with overnight lows generally
into the low to mid 50s (a bit cooler in the Piney Woods and a bit
warmer at the coast). This cooler weather will stick around
through at least Halloween.

.AVIATION...
(06Z TAF Issuance)
Issued at 1247 AM CDT Sat Oct 25 2025

Cigs at CLL have decreased to IFR ahead of the line of
thunderstorms. Winds at all terminals are southeasterly with some
gusts around 20 kts. Two rounds of thunderstorms will impact the
terminals in which case winds may become erratic and gust to 25
kts. The first line of storms will move in from the Northwest into
the early morning hours with no significant changes in timing
from earlier thinking based on the latest radar trends and hi-res
guidance, impacting CLL around 06-08Z, with the Metro terminals
seeing impacts around 08-12Z, and the Coastal terminals around
10-13Z. May see some lingering showers behind the first line of
storms, particularly close to the Metro and Coast. Otherwise,
expect a break in activity until the next round of storms is set
to move in Saturday night into Sunday morning from the Northwest,
impacting CLL/UTS 20-00Z, CXO 23-02Z, the Metro terminals 01-05Z,
with the coastal terminals later and beyond the current forecast
period; note that these times will be refined but confidence is
increasing in this second round of storms. All modes of severe
weather will be possible with both rounds of storms, with wind as
the primary threat. Large hail and isolated tornadoes could also
pose a threat.

&&

.MARINE...
Issued at 957 PM CDT Fri Oct 24 2025

Mariners should be prepared for strong to severe thunderstorms
late tonight into Saturday morning, and again Saturday night.
Strong wind gusts (over 50 knots), drastic wind shifts, and
locally high seas will be possible with any of the severe storm
that develop.

In addition, a Small Craft Advisory is in effect through at
least Saturday evening for all waters as the southeasterly winds
increase to sustained 20-25kt and gusts to 30kt. Wave heights are
expected to increase in response to the higher winds with seas
5-7ft and occasional higher seas. Winds are expected to lower
through the day on Saturday as the associated cold front
approaches from the west, but the elevated seas will likely linger
through late Saturday night or Sunday morning. So, the SCA may
need to get extended for the Gulf Waters into Sunday morning. A
brief period of offshore winds will be possible following the cold
front, but will quickly return to onshore flow by Sunday
afternoon.

A Beach Hazards Statement is in effect through Saturday evening
for a high risk of strong rip currents and elevated water levels
leading to minor coastal flooding/high wave run-up during times
of high tide.

Benign weather is expected Sunday night through Tuesday afternoon,
but a cold front is expected to pass through the coastal waters
Tuesday night or Wednesday. In its wake, strong offshore winds and
elevated seas will be possible.

.HYDROLOGY...
Issued at 410 PM CDT Fri Oct 24 2025

A FLOOD WATCH WILL BE IN EFFECT FOR MOST OF SOUTHEAST TEXAS FROM
EARLY SATURDAY MORNING TO EARLY SUNDAY MORNING.

Ahead of the upcoming heavy rainfall event, grounds/soils are on
the dry side. Majority of Southeast Texas is abnormally dry (D0)
or in moderate drought (D1). There are a few portions of the area
in severe drought (D2) including areas west of the Brazos River
and parts of Madison/Walker Counties. So, in most areas the
grounds will be able to take the rain and soak up quite a bit
before it runs off. In the areas where the drought is a bit more
severe, we'll see that rainfall become runoff much sooner. Our
rivers/bayous are in good shape ahead of this event as well, so it
would take quite a bit of rain to put those into flood. Even with
~4-6" of rain over a 24 hour period, we're only looking at
scattered instances of action stage and a low end chance of
isolated instances of reaching minor flood stage. The main concern
would be if we get those higher-end 4-6" amounts in a short
period time, which would be driven by high rainfall rates. In that
scenario is when we could see issues with flashy
rivers/bayous/streams and also street flooding especially in urban
areas and areas with poor drainage.

Flash flood guidance is generally in the 3-5" range for one hour
and 4-6" range for three hours. It's within the realm of
possibilities that we could see high rainfall rates (2-3+"/hr)
that could cause instances of flash flooding. We will also need to
monitor where the axis of heavy rain will fall during the main
storm windows (tonight into Saturday morning and Saturday evening
into early Sunday morning). If there are instances of prolonged
heavy rainfall over the Houston metro area, then we'd need to
watch the bayous a bit more closely to monitor for potential
impacts. Thankfully, there is expected to be a lull between the
rounds of heavy rain late Saturday morning into the afternoon to
allow for drainage, but elevated water levels along the coast
during high tide could briefly inhibit that drainage.
