Area Forecast Discussion
National Weather Service Houston/Galveston TX
1124 PM CST Sun Jan 3 2021

.AVIATION [06Z TAF Issuance]...

Winds are steadily decreasing and have already become light and
variable at most of the area airports. With skies remaining clear
as well, radiational cooling will be maximized. This is important
because the onshore flow we had earlier today has increased dew
points across the area into the mid-to-upper 40s. As a result, hi-
res model guidance is indicating fog development early Monday
morning in the time frame between 11z-15z. TEMPO IFR ceilings
have been added to all area airports except for CLL, UTS, and GLS.
For those three airports, MVFR visibilities have been added in
the 11z-15z time frame since their dew point depressions are not
low enough to instill the same amount of confidence as with the
other airports. Nevertheless, fog is expected to dissipate by 15z
with VFR conditions returning afterwards for all the area
airports. This is also when winds will kick back in out of the
southwest around 5 knots. On Monday evening, winds are expected to
become light and variable once again.

.PREV DISCUSSION /Issued 532 PM CST Sun Jan 3 2021/...

.DISCUSSION...

Relatively quiet weather remains the expectation this week, with
the most impactful weather feature being a midweek cold front that
will put a halt to an early week warming trend and bring in a
chance for showers and an isolated thunderstorm.

Otherwise, look for temperatures that are generally seasonable (a
little warmer than average early in the week, a little cooler than
average late in the week). Late night/early morning fog should
become more of a feature over the next couple of nights as
humidity increases ahead of that midweek front.

.SHORT TERM [Through Monday Night]...

The satellite is again quite clear, with maybe a stray scrap of
cirrus marring a completely blue sky. With the full sun and
relatively dry air, temperatures have drifted a little above
seasonal averages, into the middle to upper 60s across the area.

Winds today are south-southwesterly as high pressure moves off to
the east, which is helping to usher in some more humidity, though
it's still relatively dry - particularly inland - as we are still
moderating a drier airmass. Along with the high moving off, low
pressure far to our northwest is deepening. This tighter pressure
gradient has made winds today a little gusty as well.

Tonight, we'll see that low and perhaps even a very weak front
make its way to the area, while another high slides in behind it.
This means that while we can probably expect light winds overnight
(and perhaps some patchy fog if we have enough low level moisture
in place), we may see winds turn offshore because of this Monday.
Regardless, this will be short-lived as a more substantial low
will begin to develop in the lee of the Rockies, establishing
onshore - but that's a matter for the long term...

.LONG TERM [Tuesday Through Sunday]...

With surface high moving east of the area, onshore winds are set to
return by Tues. This along with the steady increase of moisture via
the Gulf could also signal the return of some low will also POPs by
Tues night/early Weds morning in the form of WAA-type showers along
the coast. But, the main rain chances look to be with the approach/
passage of a strong cold front and its associated upper low through
the region Weds afternoon and evening. Showers and isolated thunder
storms are likely for this time frame, but there are hints that the
cap will remain too strong for any significant/strong development.

Given the rather progressive nature of this overall pattern of late,
all this activity should be moving quickly to the E/NE by late Weds
night. Cooler temperatures along with mostly clear/sunny skies will
be back over SE TX for the rest of the week. Looking way ahead into
next weekend, not a lot of consensus so far with the the next upper
level shortwave moving in from the W/NW. ECMWF/Canadian seems to be
leaning toward one for Fri night or Sat...ahead of a more organized
upper low/trof currently progged for late Sun afternoon/night.

.MARINE...

Expect light, generally onshore winds today to stay light, but
become more offshore tomorrow. Since the winds are light, they are
also likely to be somewhat variable. Look for winds to establish
themselves as onshore again Tuesday in advance of the next
frontal passage in the midweek. Expectations are for this front
to cross the waters Wednesday night. Offshore winds and elevated
seas will develop in the wake of the front late Wednesday into
Thursday with Caution or Advisory conditions likely.

.HYDROLOGY...

For the moment, the only flood warnings in effect are on the San
Bernard River - at East Bernard, Boling, and Sweeny. The East
Bernard warning will likely be able to be canceled this evening,
as the river is falling and is nearly to flood stage this
afternoon. Warnings will be needed at Boling and Sweeny for some
time yet.

Additionally, we continue to watch Normangee closely. While
forecast crests have been slightly lower of late, it is still
above flood, and the river is forecast to reach flood stage very
late tonight. Will give things one more forecast cycle from the
RFC this evening before a final decision will have to be made.
Should expectations remain that the river reaches flood stage
tonight, a warning will have to be issued by the evening shift.
