Updated for 06z aviation.

Aviation
MVFR ceilings have developed at ali crp vct this evening and will
move into lrd within a few hours. Some ifr ceilings and MVFR vsbys
may be possible at times as well. These conditions should persist
into the morning hours before improving back toVFR levels mid to
late morning. Southerly to southeasterly winds will gust between
20 and 25 knots again during the afternoon and then subside around
00z 01z. As with the last several evening, MVFR stratus will build
back in after 00z at ali crp vct. Chances for showers and storms
will then improve towards the tail end of the forecast.

Previous discussion issued 937 pm cdt Sat may 27 2017
discussion... Convection over the higher terrain in northeast
mexico has diminished as it approached the rio grande this evening
where an axis of decreasing low level moisture and increasing
convective inhibition remains in place. Increased sky cover for
tonight as convective debris clouds cover the region at this time
and then the low stratus over the coastal areas is expected to
move inland overnight. No other changes were made to the
forecast.

Previous discussion... Issued 642 pm cdt Sat may 27 2017
discussion... Scattered convection over coahuila continues to
advance to the east-northeast at this time. Models depict an 85h
theta-e ridge axis along the rio grande into the far western brush
country through the evening hours with activity possibly being
sustained as it approaches the border. But will have to overcome
increasing convective inhibition in place over south texas. Will
monitor progress of storms over the next couple of hours. May
have to include slight chance pops for webb and la salle counties.

See aviation section for 00z tafs.

Aviation... Cirrus shield was in place over the coastal plains
with cirrus increasing from the west from convective activity over
mexico.VFR conditions will continue early this evening but low
stratus MVFR ceilings should develop in 02-03z period this evening
over the coastal plains and spread inland. MVFR ceilings will be
possible at lrd by 08z. Ifr ceilings MVFR vsbys in fog will be
possible over the coastal areas in hours before daybreak. Ceilings
will be lifting through 1500-2500 feet range by mid morning with
clouds scattering out from south to north between 16-18z. Gusty
south-southeast winds expected for coastal areas Sunday afternoon.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
