.DISCUSSION...
Issued at 1252 PM CST Sun Dec 14 2025

In the wake of last night`s cold front, temperatures are between
15-30 degrees colder than what we had this time yesterday. Skies
will clear from the east/northeast for the remainder of the day
and tonight and winds will gradually diminish. Combination of both
should allow for freezing overnight lows for a good part of SE Tx
tonight. The Freeze Watch previously in effect for locations that
haven`t received their first winter freeze has been converted to a
Freeze Warning. Also threw in Wharton and northern Brazoria
Counties where guidance trended a touch lower with temps. Kept
Galveston County out for now, as a NE wind trajectory off the
warmer bay should keep temps a few degrees above the freezing
mark (but we`ll monitor trends).

Gradual warm-up will begin Monday as cold high pressure area starts
moving further to our east and winds swing back around to a e/se
direction off the Gulf. Highs/lows will transition upward on a
daily basis and back into the 70s/50s by midweek.

Mid-upper trof will pass across the state Tue night-Wednesday night.
We should see enough of a moisture return by then for some scattered
shower and/or isolated thunderstorm development. The next cold
front, Pacific in origin and not nearly impressive as the current
one, is penciled in for Thursday afternoon & evening followed by
a quick return of the warm muggies heading into next weekend. 47

.MARINE...
Issued at 1253 PM CST Sun Dec 14 2025

Moderate-strong north to northeast winds 20 to 35 knots and
elevated seas will continue into the overnight hours before
slowly diminishing after midnight. Small Craft Advsy remains in
effect for the bays, and will transition the Gale Warning in the
Gulf back down to a SCA later this evening once gusts begin to
subside. Continued improvement is anticipated Monday. Winds will
gradually veer around to the east and southeast as high pressure
tracks away from the region. Light to moderate onshore flow will
then prevail through Thursday. We will need to be on the lookout
for some sea fog development Wednesday and Thursday in between
bouts of scattered showers and isolated thunderstorms. The next
front is forecast to push off the coast Thursday night. 47
