Area Forecast Discussion
National Weather Service Brownsville TX
417 AM CST Tue Jan 2 2018

.SHORT TERM (Now through Wednesday): Surface observations indicate
that freezing temperatures are occurring over the northwest corner
of the BRO CWFA, with the remainder of the area experiencing
temperatures just a few degrees above freezing, likely due to
moderate to breezy winds and overcast skies. A Freeze Warning
remains in effect for all of Deep South Texas and the Rio Grande
Valley except the coastal portions of Cameron and Willacy Counties,
with a Wind Chill Advisory in effect for the entire area. KBRO
Doppler radar shows light precipitation confined to the adjacent
Gulf of Mexico waters.

For today, the aforementioned Freeze Warning and Wind Chill Advisory
will expire around mid-morning. Meanwhile, weak inverted surface
troughiness along the Lower Texas Coast, combined with a 500 mb
trough dropping into the Central Plains, will produce isolated to
scattered precipitation along and east of the Interstate 69E
corridor. An analysis of forecast soundings suggest that not enough
sub-freezing air will exist in the lower levels of the atmosphere
to produce any frozen precipitation.

Tonight, another Freeze Warning and Wind Chill Advisory has been
issued for all of Deep South Texas and the Rio Grande Valley. As the
500 mb trough rapidly moves east and southeast past the Mississippi
River Valley, and surface high pressure plunges into Texas and
brings a surge of much drier air, precipitation will be isolated
along and east of the Highway 69E corridor, and should end well
before surface temperatures reach the freezing mark. Thus, freezing
rain is not anticipated at this time and neither is sleet.

On Wednesday, the continued surge of much drier air and surface high
pressure becoming positioned over the BRO CWFA will result in dry
weather. Temperatures will finally begin to moderate as nearly
clear skies will be in place beginning around sunrise.

.LONG TERM (Wednesday Night through Monday): The main impacts in
the long term will come Wednesday night as another shot of cold,
arctic air brings freezing temperatures to Deep South Texas
Thursday morning. A mid-level shortwave trough will move eastward
into the Southeast U.S., bringing strong subsidence into our
region Wednesday night. N/NW flow and much drier air will allow
for clearing skies, which may drop temperatures several degrees
below freezing in some locations. Most model guidance continues to
show low temperatures in the 26 to 32 degree range, so additional
Freeze or Hard Freeze Warnings will be possible. The somewhat
good news is wind chill values should not be much cooler than the
ambient temperatures as winds will be lighter at around 5 mph.

The rest of the week, mid-level ridging will build over the
Southwest U.S. with east to southeast flow returning to the
surface across South Texas. Dew points will slowly rebound with
temperatures struggling to reach normal for early January. This
weekend, normal to above normal temperatures will finally return
with highs in the low to mid 70s. There is only a very slight
chance of a shower each day as moisture will remain confined to
the surface to 850mb. The next cold front may come early next
week as the next storm system develops in the Central Plains.

&&

.MARINE (Now through Wednesday): Buoy 42019 reported north-northeast
winds around 16 knots gusting to around 21 knots with seas slightly
under 6 feet with a period of 7 seconds at 03 CST/09 UTC. Increasing
winds and building seas are expected along the Lower Texas Coast as
surface high pressure plunges south into Texas and tightens the
pressure gradient. As a result, Small Craft Advisories have been
raised and extended until sunrise Wednesday morning. Additional
Small Craft Advisories may be needed for the remainder of
Wednesday.

Wednesday night through Monday: Surface high pressure will shift
to the east, returning a lighter easterly flow for the rest of the
week. Marine conditions will improve with seas dropping to 1 to 3
feet Friday and Saturday. Winds will increase this weekend out of
the southeast with seas building to 4 to 6 feet Saturday night
through Monday as the next storm system develops in the Central
Plains.
