Aviation
Mostly all is quiet across the SE tx TAF sites this evening
besides a stray shower which went across iah and is now in the
vicinity of cxo, as seen via radar imagery. The occasional
streamer shower will be possible through the overnight hours and
into the morning. Still sticking to a persistence forecast, with
the main change being weaker winds across the area, though still
gusty at times, just not as strong. MVFR ceilings continue across
all terminals, with the occasional lift toVFR. MVFR ceilings
will continue through tomorrow mid morning. Gusty winds should
pick back up further inland and mostly west of i-45 my mid morning
tomorrow. Over this region winds should remain out of the
southeast and gust between 17-23 knots through the afternoon
hours. Ceilings should rise toVFR by early afternoon area wide,
before MVFR ceilings return once again tomorrow evening. Guidance
has backed off slightly on how early to bring MVFR ceilings
tomorrow night. Given the drier air ushering in with the ridge off
to our east, we could see the onset of high MVFR ceilings a touch
later tomorrow night.

discussion...

a weak upper level disturbance over SE tx will weaken and move off
to the east tonight. Showers are stubbornly holding on this
evening and will carry pops through 03z before the activity wanes.

Low level moisture will continue to stream into the area beneath a
capping inversion and would expect clouds to fill in as the night
progresses. Just like the past couple of nights, winds don't fully
decouple and the combination of clouds and winds will keep mint
above normal and probably in the mid upper 70's. Although the
disturbance weakens and moves east, streamer showers still look
possible later tonight and actually for the next couple of nights.

Will add isolated showers for the coastal counties and around the
bays from 09-12z. Looking ahead, no changes to the holiday weekend
forecast as upper level ridging begins to impinge on SE tx from
the east. Overall, the weekend looks warm and dry with just a few
streamer showers late at night. Tweaked hourly grids and raised
mint a degree or so. 43

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

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.
