Synopsis for the middle texas coastal waters.. Moderate to occasionally strong winds will continue across the coastal waters tonight. Elevated seas will persist over the gulf waters tonight also. Winds are expected to restrengthen Wednesday to strong levels with advisory conditions likely to continue through Wednesday for both winds and seas. Small craft advisory conditions will likely continue through Thursday as low pressure persists out west with strong southeasterly onshore flow. Some improvement in winds can be expected this weekend. However, southeasterly swells will continue to be elevated. Little to no precipitation is expected through early next week.

area forecast discussion... Updated
national weather service corpus christi tx
952 pm cdt Tue may 21 2019

Discussion Low level moisture clouds continue to drift inland
over the coastal plains as the sea breeze boundary moves west
into the brush country. No major changes were made to the forecast
with a slight bump up in minimum temperatures tonight. See marine
section for adjustment to small craft advisory.

No changes will be made to the current coastal flood advisory. The
latest trend in tide levels continue to show a decrease in the
above normal tides. If this trend continues during the night, the
tide levels may not reach advisory criteria. Will let the midnight
shift determine if extension will be needed.

Marine Pressure gradient behind the sea breeze boundary appears
to be enough to keep winds close to SCA over the southern nearshore
water this evening. The low level flow will be increasing to 30-35
knots overnight as well. Winds are expected to remain close to sca
levels through 12z for this area. The SCA may need to be extended
further on Tuesday as pressure gradient strengthens with low
pressure area forming over the southern high plains.

Prev discussion issued 654 pm cdt Tue may 21 2019
discussion... See aviation section for 00z tafs.

Aviation... Dryline boundary moved as far east to just west of a
line from beeville to falfurrias this afternoon. Now, the sea
breeze boundary from vct-bea-ali was slowly pushing inland. The
visible satellite image shows the extensive smoke haze plume over
the northwest gulf of mexico into the coastal plains that will
limit vsbys to 5-6sm this evening into the overnight period.

Expect MVFR ceilings will develop over the coastal areas by 06z
and spread inland as low level south-southeasterly flow increases
to 25-30 knots. MVFR ceilings will reach the brush country 09-10z.

Tempo conditions of ifr ceilings MVFR vsbys will occur from
09-13z over the coastal plains. Southeast winds will become gusty
over the coastal region by 15z with MVFR ceilings persisting into
the afternoon.VFR conditions will return to the brush country by
early afternoon. Wind gusts will approach 30 knots in the southern
coastal bend as the gradient increases with a trough of low
pressure deepening over the southern high plains.

short term (tonight through Wednesday night)...

dryline boundary currently converging with the sea breeze boundary
this afternoon. However, due to a strong cap, convection is being
inhibited from developing. The cap is progged to remain strong
through Wednesday and Wednesday night. Moisture will also be
limited, thus am not anticipating any precip through the short term.

Kept silent 10 pops across the northeastern CWA tonight and the
northern tier of the CWA Thu night. This is where the cap is progged
to be weakest and could see a rogue shower. Also, some of the models
were showing light QPF and pops approaching 20 percent in these
areas. But given the cap, did not want to mention precip at this
time.

Temps across the western CWA will be very warm to hot with highs
around 100 along the rio grande plains. Humidity will also be
elevated and the combination may lead to heat indices of 105-109
across the western CWA Wed afternoon.

Breezy to windy conditions are expected once again wed, but not
quite as windy as today. Low pressure is progged to develop deepen
along the rockies and across W tx leading to a tightening pressure
gradient.

Will continue the coastal flood advisory through tonight as tides
continue around 1 foot inundation (2 feet above msl) during times of
high tide. Above normal trends have been decreasing this afternoon,
therefore tide levels are not expected to be quite as high as
today's values.

Long term (Thursday through Tuesday)...

dry and hot expected in the extended through memorial day weekend
and into next week. A ridge of high pressure will build westward
across south texas, with drying aloft. Expect to see afternoon highs
climbing into the upper 90s to around 100 degrees for the rio grande
plains through the period, with 80s to lower 90s elsewhere. Weak
waves in the southwest flow aloft out to the west could help
generate a few light showers, but confidence is very low based on
the strength of the ridge and dry air aloft. Will keep a dry
forecast through the extended. May have to watch heat index values
as low level southeasterly flow will continue to keep surface
dewpoints high through the period.

Marine...

winds have decreased this afternoon, but are expected to remain at
moderate levels through tonight. Large seas are expected to continue
overnight, thus maintaining the advisory conditions. Winds are
expected to restrengthen Wed and Wed night and the SCA may need to
be extended for both wind and seas through Wed night.

Adverse marine conditions expected to continue through the
weekend and into early next week. Strong southeasterly southerly
flow is expected to continue through the upcoming weekend as a
strong high pressure system sets up across the southeastern us.

Pressure gradient does somewhat relax by Saturday and Sunday, but
southeasterly swells will continue to remain elevated. This will
likely keep SCA conditions despite the slightly low winds. Winds
will begin to increase once again by Tuesday as surface
cyclogenesis develops east of the mexican plateau.
