Aviation
Sticking close to a persistence forecast through the TAF period.

MVFR ceilings continue across SE tx terminals this evening and
will hold through early morning. Moderate southeasterly winds
continue and will increase in speed again by early morning,
helping to mix out MVFR ceilings across most TAF sites. Drier
conditions should work in over the region by tomorrow morning,
besides a tongue of moisture anticipated to pool over our
southwestern zones, potentially impacting sgr and lbx. Some of the
short term guidance such as the SREF and arw are developing some
showers over this region in the early afternoon hours, but kept
all TAF sites dry through the period for now.VFR ceilings look
likely for the northern and metro terminals by mid morning, with
the coastal terminals potentially holding on to high MVFR decks
through the afternoon. These sites may too scatter out by the mid
afternoon hours. With the pressure gradient remaining rather tight
over the region, expect gusty conditions to continue into
tomorrow evening. MVFR ceilings look to return once again by the
early evening hours across SE tx.

discussion...

at 7 pm, low pressure was located over SW tx. The pressure
gradient across the state remains tight and winds will remain
breezy tonight. Low level moisture will continue to stream into
the area beneath a capping inversion. Low temperatures will not
cool much overnight and bumped temps up a degree or so in places.

Houston may once again endure a minimum temperature near 80
degrees. A weak upper level disturbance will undercut the upper
level ridge centered over the SE us and this feature could trigger
a few showers late tonight near matagorda bay. If any showers
develop, they'd likely move north across the western half of the
cwa. 43

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.
