NWS Brownsville, TX wrote its last area forecast discussion before this gale warning went out at Dec 30, 11:29 AM CST, 2 hours 27 minutes earlier.
Area forecast discussion, Dec 30, 11:29 AM CST, 2 hours 27 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Brownsville TX
1129 AM CST Wed Dec 30 2020
.DISCUSSION...Updated for latest aviation discussion below.
&&
.AVIATION...VFR conditions will prevail at all aerodromes through
this evening and into the overnight. Strong southeasterly winds
will continue into this afternoon with gusts up to 35 kts. Showers
and thunderstorms are expected to develop tonight ahead of a cold
front this evening and overnight with rain lingering into late
morning. MVFR ceilings are expected for a few hours Thursday
morning before returning to VFR. Strong northwesterly winds are
expected in the wake of the cold front passage with gusts up to 35
kts on Thursday.
&&
.PREV DISCUSSION... /issued 547 AM CST Wed Dec 30 2020/
DISCUSSION...Updated for latest aviation discussion below.
AVIATION...Strong southeast/south winds will continue today as a
strong mid-level low approaches from the west. The low-level jet,
around 850 mb, is forecast to mix down to the surface later this
morning leading to very breezy and gusty surface winds through
much of the day, with gusts near 35 knots at times. Showers and
thunderstorms are expected to develop along and ahead of a strong
cold front late this evening and overnight.
PREV DISCUSSION... /issued 405 AM CST Wed Dec 30 2020/
SHORT TERM (Now through Thursday): Latest GOES-16 WV satellite
imagery shows a mid-level shortwave trough over New Mexico.
Brownsville Radar currently shows some ongoing streamer showers
moving across the lower Texas coastal waters. Also, VAD Wind
Profile is indicating winds between 35 to 45 knots at 2000 feet
AGL early this morning.
Breezy to windy conditions are expected today, especially near the
coast, as the low-level jet mixes down to the surface. A Wind
Advisory has been issued for Cameron, Willacy and Kenedy counties
from 10 am until 2 pm today. Otherwise, above normal temperatures
will continue today will highs in the low to mid 80s at most
locations under a mix of sun and clouds. Rain chances will increase
across the region later this afternoon into tonight as the 500 mb
trough across northwest Mexico moves eastward as a strong cut-off
low and surface low pressure develops across northeast Mexico.
The combination of these features and abundant moisture in place
will provide showers and elevated thunderstorms across the area
tonight ahead and along cold front. The Storm Prediction Center
/SPC/ has placed areas along the coast, Cameron, Willacy and Kenedy
counties, under a marginal risk of severe thunderstorms. The main
threats with these storms will be damaging wind gusts. The cold
front and the associated surface low moves offshore the lower Texas
coast Thursday morning and the 500mb low moves into southwest Texas
Thursday morning. Much cooler air filters into the northern
ranchlands and Rio Grande Valley in the wake of the front late
tonight into Thursday. Some elevated convection will be possible
behind the front during the morning but this is expected to quickly
end in the morning due to strong subsidence. Breezy to windy
conditions in the wake of the front may support Wind Advisories near
the coast on Thursday. Lows tonight, depending on the timing of the
front, will generally range from the mid 40s to upper 40s across the
west to the low to mid 50s near the coast. Highs on Thursday will
mainly be in the low to mid 60s.
LONG TERM (Thursday Night through Tuesday): Precipitation will
push off to the east by Thursday evening while the pressure
gradient across the CWA begins to weaken, allowing for winds to
follow suit. A chilly morning is then expected to start 2021 with
lows ranging from the middle 30s in the northern ranchlands to the
middle 40s in the lower RGV. Another quick-moving mid-level
shortwave will swing through the area on Friday afternoon and
evening, bringing another weak cold front across the area
overnight which will act mainly as a reinforcing shot of cooler
air. Rain chances look relatively minimal with the weaker Friday
night/Saturday morning front due to lack of moisture return flow.
Saturday night low temperatures will also be fairly chilly
especially compared to seasonal normals. By Sunday we will begin
to see return flow set back up across the area, allowing for
temperatures to warm back up to near seasonal normals to start the
new work week. From Monday evening onward there is a bit of
discrepancy between the models’ respective interpretations of
the mid-level patterns heading into the middle of next week. There
is some moderate agreement on increased rain chances for most of
the CWA Tuesday, with the timing of any precipitation very much up
in the air. Have increased some PoPs as a result, and will
continue to monitor for additional details.
MARINE (Now through Thursday): Radar images continue to indicate
a few streamer showers moving across the lower Texas Gulf waters
this morning. A strong pressure gradient will continue across the
western Gulf of Mexico today ahead of an approaching cold front.
Moderate to strong south-southeast winds will prevail across the
lower Texas coastal waters today with Small Craft Advisories in
effect for the Laguna Madre and the Gulf waters. Showers and
thunderstorms, some possibly strong, will develop across the
coastal waters tonight into early Thursday morning with the
approach of a strong cold front.
In addition, Small Craft Advisories are in effect for the Laguna
today and Gulf waters today and tonight due to the strong south to
southeast winds. Strong to very strong offshore flow will develop
across the marine area in the wake of the front. A Gale Watch
remains in effect for the lower Texas Gulf waters for Thursday.
Thursday Night through Tuesday: Strong winds will be ongoing over
much of the coastal waters in the wake of Thursday’s strong cold
front. Gale-force winds will subside Thursday evening, with Small
Craft Advisories likely needed through around midday Friday due
to elevated seas. Seas then briefly subside Friday before
northerly flow sets up behind another weak cold front. Persistent
northerly flow will favor some building seas before the surface
flow weakens later Saturday night into Sunday. Onshore flow then
sets in for Sunday and remains in place through the end of the
period. Persistent southerly to southeasterly flow may favor some
building seas early next week.
