.DISCUSSION...
Issued at 1141 AM CST Thu Dec 4 2025

Several locations around the Houston Metro and Coastal Plains have
finally made it to the 50 degree mark. Elsewhere, temperatures
remain in the mid to upper 40s. Have brought the highs down a few
degrees due to the persistent cloud deck and CAA. Light drizzle
continues across portions of the area this afternoon.

Lingering moisture and a passing upper level disturbance will
result in scattered showers and isolated thunderstorms continuing
along the coast Friday into Friday night.

Lows tonight through early next week will generally be in the
upper 30s to 40s. Sunday`s lows will be slightly warmer with
temperatures in the 40s to mid 50s.

Highs will remain in the 40s to 50s through Friday, before warming
into the 60s to low 70s for the weekend. A reinforcing cold front
will move through Sunday night, ushering in another round of
colder temperatures to start off the next week.

(12Z TAF Issuance)
Issued at 539 AM CST Thu Dec 4 2025

Widely scattered SHRA, areas of drizzle, and low cigs expected
today. Drizzle, patchy fog, and low clouds will also result in
reduced visibility. LIFR/IFR conditions expected to continue
through the TAF period. Winds will increase from the north today,
particularly near the coast where winds could gust 25-30 knots
this afternoon and evening. By tomorrow morning, another round of
scattered SHRA is expected to develop, with the best chance of
morning rain being in our southern and coastal zones.

.MARINE...
Issued at 1141 AM CST Thu Dec 4 2025

Widely scattered showers and isolated thunderstorms will continue
through the afternoon as the front sits just offshore. Moderate
to strong northerly winds will develop behind the cold front of
around 20kt with gusts to 25kt. A Small Craft Advisory has been
issued for this afternoon into tonight. These strong offshore
winds plus already low astronomical tides will lead to lower than
normal water levels in the Bays during low tide Friday morning,
down to around 0.5ft below MLLW. Winds lower through tonight with
light to occasionally moderate northeasterly winds persisting
through Saturday. Lingering moisture and passing upper- level
disturbance will bring continued chances of scattered showers
Friday into Saturday.

Drier conditions return by Sunday, but a reinforcing cold front is
expected to move through the coastal waters Sunday night bringing
a brief period of moderate to strong northerly winds that
persists into Monday morning.
