Discussion
Note aviation discussion corresponding to the 00z tafs.

Aviation
Predominate breezy windy andVFR conditions this evening will
transition to predominate MVFR and a gradual decrease in onshore
wind tonight early Thursday morning. Low level jet overnight yet
anticipate wind shear below the llws threshold. Expect a
transition to breezyVFR conditions from late morning to early
afternoon Thursday.

Prev discussion issued 356 pm cdt Wed may 22 2019
short term (tonight through Thursday night)...

satellite and upper air analysis shows a strong ridge over the
southeastern us and a deepening longwave trough over the
southwest. At the surface, a tight pressure gradient continues
over south texas between a lee trough to the west and a ridge over
florida. Winds will continue to remain a concern through the short
term, with speeds of generally 15 to 25 mph with gusts over 30
through this afternoon into tomorrow. Heat will also be a problem
through tomorrow, with plenty of low level moisture being pumped
in from the gulf, and warm afternoon highs due to the influence
of the ridge. Heat index values will continue to hover a little
below advisory criteria tomorrow. Drier air aloft will continue
to limit precipitation chances.

Long term (Friday through Wednesday)...

not much change with the extended forecast. S tx will remain between
an upper level high located over the southeast u.S. And a trough
across the western u.S. Through at least the weekend. The trough
begins to shift east the first part of next week, but overall a
south to southwest flow aloft will persist. Some models show light
qpf at times through the weekend, however the moisture is progged to
limited and confined to the lowest levels. The cap also is progged
to persist through Monday. By tue, models show sufficient moisture
in place as pwats increase to around 1.6-1.8 inches and the upper
trough approaches W tx. Thus, included 20 pops Tue Wed across
the eastern CWA where the highest pwats are expected to be located.

Otherwise, partly cloudy skies with humid conditions are expected
through the period. Temps will be slightly above normal along with
breezy to windy afternoons.

Marine...

a moderate to at times strong onshore flow is expected to persist
through the period. Advisory conditions will be possible at times.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
