The dreary conditions will continue through Friday for SE Texas
with mostly cloudy skies and chilly weather. Area will remain
mostly rain-free through sunrise (other than some spotty areas of
drizzle possible), but scattered light rain showers will return
along the coast by daybreak with continued chances likely through
Friday evening. Greatest chances of showers will be off the coast,
but areas along and south of I-10 may see some light rainfall.
The rainfall will be largely stratiform rain (a slow, steady
rainfall), not convectively driven showers like typical SE Texas
rainfall. Afternoon high temperatures will be in the low 50s
across much of the region, but may struggle to rise out of the
upper 40s if rain coverage is greater than expected. With overcast
skies persisting into overnight Friday night into Saturday
morning, low temperatures will be dropping into the low to mid 40s
across much of the region and staying in the upper 40s to low
50s.

The mostly cloudy skies will persist Saturday morning, but skies
will begin to clear northwest to southeast through the day. The
breaks in the clouds and a light southerly wind will bring high
temperatures closer to normal - in the mid to to upper 60s. These
warmer conditions will continue into Sunday with mostly sunny
skies expected, and with areas along and south of I-10 likely
climbing into the low to mid 70s. Enjoy your time with this milder
weather because a dry cold front moving through the area Sunday
afternoon/evening will lead to a return of cold temperatures to
start the work week. Overnight lows will return to the upper 30s
to mid 40s across much of the area Sunday night (and a breezy
north wind will make it feel colder). High temperatures on Monday
will be in the mid 50s to low 60s across the area. Dry conditions
with a gradual warm-up is then expected through the remainder of
the week.

Issued at 1009 PM CST Thu Dec 4 2025

Extended the Small Craft Advisory through late tonight as wind
gusts up to 25kt persist, and small craft will likely need to
exercise caution through Friday morning. Scattered to widespread
light to occasionally moderate showers are expected to develop by
daybreak and persist through Friday night. These showers will
exit to the east by Saturday morning. Light northerly winds
expected through early Saturday afternoon with winds veering to
onshore by Saturday evening. These onshore winds will not last
long as winds turn northwesterly Sunday afternoon following the
passage of a dry cold front. Strong northwesterly winds of
20-25kt with gusts to 30kt develop Sunday evening and continue
into Monday morning. These strong winds will also lead to seas of
5-7ft during this timeframe. Conditions improve through the day on
Monday with light north to northeasterly winds expected by Monday
night.
