Discussion
Updated for 06z aviation.

Aviation
Weak frontal boundary will move through south texas overnight with
winds shifting around to the northeast. Low clouds and some showers
may accompany the front and have included MVFR ceilings and vcsh
remarks at ali crp lrd. The northeast winds will become gusty (in
excess of 20 knots) later this morning and continue into the
afternoon hours. The winds will diminish late in the afternoon to
10 knots or less and will remain relatively light through the rest
of the period. Ceilings will improve during the day withVFR
conditions expected by the afternoon hours at ali crp lrd. Vct
should remain atVFR levels through the period.

Previous discussion issued 920 pm cdt Wed apr 18 2018
discussion... The weak frontal boundary that was from victoria to
laredo has stalled with the boundary back north of victoria again.

Will have to wait for the next surge to arrive later tonight. Will
remove slight chance pops for rest of this evening and keep the
isolated showers in the forecast overnight as the front moves
through. Appears the stronger winds will have a later arrival into
the coastal waters. Winds may increase to SCA over the gulf waters
by 15z but confidence not strong at this point. Will let the mid
shift pinpoint the timing of the stronger winds.

Previous discussion... Issued 650 pm cdt Wed apr 18 2018
discussion... See aviation section for 00z tafs.

Aviation... Cold front is slowly sagging south through the region
at this time, along a line from south of victoria to beeville to
just north of laredo. The front will be near the coast by midnight
with northeast winds increasing during the overnight as high
pressure builds into the area. Ceilings in the 4-5 kft range this
evening will lower to MVFR behind the front with the possibility
of isolated showers across the area. Drier air will arrive behind
the front in the vct area first with conditions improving toVFR
late tonight and skies clearing by 18z Thursday. Ceilings will
lift toVFR over the coastal bend by 16z with scattered clouds
prevailing by the afternoon. MVFR ceilings will hold on a little
later for the lrd area through 21z before lift toVFR levels.

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.
