1246 pm cdt Sat mar 23 2019

Discussion A little more sunshine over the coastal bend has
provided a little more mixing with stronger winds occurring with
breezy conditions over the inland coastal bend. Adjusted wind
speeds accordingly for this afternoon. See aviation section for
18z tafs.

Aviation MVFR ceilings will continue into mid afternoon over
the brush country. Otherwise,VFR ceilings are expected for most
of south texas through the afternoon into early evening. Gusty
southeast winds will occur over the inland coastal plains this
afternoon with gusts above 25 knots at crp. Expect MVFR ceilings
will redevelop late this evening between 04-06z over most of
the region. The ceilings will lower to ifr between 08-11z with
patchy fog over the inland coastal plains. The best chance for
fog will be in the victoria crossroads where MVFR vsbys could
occur from 10-14z Sunday. The ceilings will lift to MVFR from
15-16z over the entire region with southerly winds developing.

Prev discussion issued 1011 am cdt Sat mar 23 2019
discussion... 12z crp sounding showed a strong inversion just
below 700 millibars. Forecast soundings show this strong inversion
will remain over south texas through the afternoon. There will be
just enough warm air advection within the moist layer below the
inversion to provide a slight chance of showers, mainly over the
inland coastal plains into the brush country. Most of the hi-res
models depict some light showers from late this morning into the
afternoon. But removed the mention of thunderstorms from the
forecast. Adjusted the wind speeds up slightly for today. But no
changes were made to the current temperature forecast.

Marine... A moderate southeast flow is expected today. The winds
may approach scec levels over the southern bays and the offshore
waters. Removed the mention of slight chance of rain for today.

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.
