Discussion 12z crp sounding indicated very warm temperatures
of 22 degrees c around 85h. Southwesterly flow at this level will
continue to increase warmth at this level close to 25 degrees c
this afternoon. Forecast of well above normal temperatures is
still on track for today. Stratus has persisted over the brush
country a little longer than expected but satellite imagery shows
a rapid decreasing trend in the past hour. Visible images show an
influx of moisture/clouds moving northward over the gulf waters of
the middle and lower texas coasts. Southerly flow will bring this
area of cloud cover into the mid-coast and victoria crossroads
this afternoon. Will hold on to cloud cover over this region for
most of the afternoon. This will lead to slightly lower high
temperatures from rockport to goliad and eastward. Breezy conditions
will continue for the coastal plains with windy conditions for
the southern coastal bend.

Marine Southerly winds have been a little slower to increase
mainly over the offshore waters. Wind speeds have already
increased to SCA along the coast from port aransas southward.

Expect wind speeds will continue slow to SCA over the offshore
gulf waters by this afternoon. Made no changes to current sca.

Aviation...

goes-r fog imagery is showing the clouds with CIGS between 1500
and 2500 feet (mainly) to be moving or already over the eastern
terminals. Thus, have MVFR CIGS going eastern terminals but some
breaks possible kcrp as there are some thin-ness in the cover
here. Farther west, will keep the tempo MVFR CIGS as last couple
of fog imagery shows some clouds developing along the rio grande.

Vsbys are 10sm, so removed any mention of fog. Winds increase as
MVFR clouds dissipate and/or raise during the day over the eastern
terminals, with winds diminishing by early afternoon at klrd with
passage of surface boundary. Winds also weaken later in the
afternoon at kali for the same boundary. Should haveVFR all
terminals AOA 19z (kvct last one to goVFR) with breezy south
winds. Except at kvct where temp/dew point depressions are
expected to not be large after sunset (like other terminals), will
delay the MVFR CIGS until after 06z (it will be before 06z at
kvct). Winds stay up too, delaying MVFR conditions. Winds taper
off late, with winds shifting west at klrd before end of terminal
forecast.

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.
