Area Forecast Discussion
National Weather Service Houston/Galveston TX
1135 AM CST Sat Dec 17 2016

.AVIATION...
Clouds continue to erode across SE TX and MVFR/VFR cigs to
prevail for much of the afternoon. Winds will begin to mix
especially in the western corridor so kept guts for KLBX/KSGR and
KCLL. A strong cold front will approach from the north this
evening. Ahead of the front a brief period of IFR cigs could
develop near the coast along with some dense fog. Aviation
interests should prepare for an abrupt wind shift to the NW-N
tonight and a increase in speeds in the wake of the front.
Instability is limited so maintained showers with the fropa.
Strong winds expected most of Sunday with generally VFR
conditions. 43

&&

.PREV DISCUSSION... /ISSUED 1004 AM CST Sat Dec 17 2016/

UPDATE...
Strong WAA continues across the area with gusty southwest winds
and mostly cloudy skies. A few sprinkles this morning and may see
some showers underneath the cap this afternoon mainly south and
east of a Columbus to Crockett line. Temperatures running well
above normal and with a few breaks in the cloud cover this
afternoon temperatures should easily reach the upper 70s to lower
80s. Windy and cold tonight in the wake of the arctic cold front.

45

ARCTIC COLD FRONT PUSHES THROUGH SE TEXAS TONIGHT...

DISCUSSION...
Latest observations have temperatures in the upper 60s to low 70s
with a very moist/humid airmass over SE Texas. In about 24 hours
that will change as an arctic cold front pushes through the area
and temperatures plummet during the early morning hours of Sunday.
At 10Z the cold front was located over central Oklahoma. Upper
level pattern shows strong trough axis from the Canadian prairies
SW towards the Great Basin/Four Corners region where an upper
level low is beginning to move east. This low should shear out as
it moves into the plains by this evening. Overall there is not a
lot of change in the forecast data so here are a few highlights.

Severe Weather Threat...quite simply there is not much of a
threat. SPC has moved the marginal risk east out of the area
mainly due to there being a strong cap ask discussed previously.
There may be an isolated strong storm or two along the front but
the severe risk will be rather limited.

Cold Front Timing...College Station to Huntsville by 8-9PM
tonight. Houston area around 11PM to midnight. Upper Texas Coast
by 1-2AM Sunday.

Potential Freeze...Temperatures will be dropping into the 30s
behind the front by Sunday morning. A freeze warning may be needed
for Burleson, Brazos, Grimes and Washington counties Sunday
morning. If temperatures do not drop below freezing in these areas
Sunday then one will be required Monday morning as temperatures
should be in the 20s. A freeze warning may be needed for a large
portion of SE Texas Monday morning. Even some of the coastal
counties may need a freeze warning since the freezing line could
reach the coast. Temperatures will need to be watched since it
will still be windy but clouds should be clearing.

Note...no frozen precipitation is expected with this event.

Winds/Wind Chill...Winds will be quite strong behind the front so
a wind advisory will likely be needed for the area starting Sunday
morning and continue for much of the day. Winds will likely be
about 20 to 25 mph from the north with some gusts. This means that
wind chill values during the day Sunday into Monday will be in the
teens to low 20s at their lowest.

High pressure will build over the Plains through the weekend and
early next week. Surface ridge Monday into Tuesday will stretch
from Texas to New England which will keep cold conditions in
place. Wednesday there is some return flow off the Gulf so
temperatures begin to moderate more. There is a short wave trough
that both the GFS/ECMWF/Canadian bring across the plains.
ECMWF/Canadian are a bit faster with the trough. Another cold
front pushes through with this system on Thursday. Return flow is
rather weak so only slight rain chances are expected going into
Thursday ahead of the front.

By the end of next week model solutions diverge quite a bit but
the GFS/ECMWF do hint at a trough developing over the central U.S.
for next weekend. The models have varied quite a bit in the
strength of this system compared to yesterday's runs. Possible
another front could push through for the weekend. Overall
temperatures will be held in check with climo or even a few
degrees below.

Overpeck

MARINE...
Deepening low pressure in the lee of the Rockies has tightened
the pressure gradient and small craft conditions exist in the
20-60nm waters. Though it may relax a little for a brief period
this evening, the small craft has been extended to the opening of
the gale watch as the gradient is expected to keep southerly winds
near to a little above 20 knots in that area for the majority of
that stretch. Cooler shelf waters also create the potential for
sea fog underneath near-surface air with such high dewpoints. To
this point, only limited reductions in visibility have occurred,
but it's also hard to justify dropping the marine fog advisory
with so little change in the environment. Will leave it up for now
out of an abundance of caution, but it may be cut loose early if
more significant fog still fails to develop in the late night
hours.

Next up, the very well-advertised strong cold front still looks
to cross the coastal waters Saturday night. Winds will quickly
shift to the north behind the front between midnight and 3 AM.
They will then quickly increase and sustained winds near 30 knots
seems reasonable with frequent gusts to 40 knots and perhaps even
a little higher on occasion. A Gale Watch remains in effect for
all waters for Sat Night through Sunday, but expect final
decisions to be made on a gale warning later in the morning. The
strong offshore winds may also produce some low water issues on
Sunday over the upper reaches of the Bays, and a low water
advisory has been issue until wind trajectories become a little
less favorable on Sunday afternoon. A moderate northeast wind will
prevail through Tuesday night.

Looking farther ahead, another strong cold front is expected in
the mid to late week, most likely late Wednesday or Thursday.
