Moderate onshore flow is expected tonight through Sunday night with small craft exercise caution headlines in place for the bays and gulf waters, especially for areas south of port aransas. Weak to moderate onshore flow is expected Monday through Wednesday before becoming weaker Thursday.

Updated for 00z aviation discussion.

Aviation
Vfr will again be the prevailing conditions for the period, with
the possibility of some MVFR cig vsby in the morning hours.

Confidence in this is low in vct and crp, so left the mention out
of those tafs, but did include this in the ali TAF as confidence
is a bit higher. Winds will likely remain light to moderate for
the majority of the period with winds slightly stronger than
usual for much of the period, particularly along the coastal bend
and coastal plains. Precipitation is not a factor for the area
tonight through Sunday, with very little chance of showers or
thunderstorms over land.

Prev discussion issued 350 pm cdt Sat aug 17 2019
short term (tonight through Sunday night)...

midlevel ridge situated across texas will continue hot conditions
through the weekend. Moisture in the lower levels will continue
humid conditions at the surface, as well as slight chances for
showers to develop mainly across the gulf waters during the
overnight and early morning periods. Heat indices over 100f
degrees are expected across south texas, with a heat advisory
currently in place for the southern coastal bend this afternoon.

Will likely see another heat advisory for Sunday, although there
may be a bit more coverage than today. The only relief will be the
breezy conditions that develop in the afternoon as the thermal
gradient sets up.

Small craft exercise headlines will remain in place for portions
of the bays and gulf waters, especially for areas south of port
aransas, as moderate onshore flow develops this afternoon due to
the thermal gradient and then overnight from mixing with the low
level jet.

Overnight lows will continue to run above seasonal normal with
lows in the upper 70s across much of the inland areas to low to
mid 80s. Along the coast and rio grande.

Long term (Monday through Saturday)...

the upper ridge is expected to gradually move westward during the
period, resulting in a weakening of the upper geopotential height
field over the ern CWA msa. The GFS and ECMWF deterministic predict
greater moisture to advect onshore early in the period, with pwat
values above normal over the ERN cwa. Deterministic and ensemble
output suggest that a surface trough will enter the bay of campeche
Tuesday Wednesday and influence the msa Thursday Friday. Anticipate
that the combination of even greater moisture surface trough will
contribute to scattered convection Friday Saturday. Expect maximum
heat index values to fall below advisory criterion by Tuesday.

Marine...

hot and mostly dry conditions are expected across the middle
texas coastal waters Sunday. A few streamer showers will be
possible tonight and then again Sunday night across the gulf
waters. Moderate onshore flow is expected tonight through Sunday
night with small craft exercise caution headlines in place for the
bays and gulf waters, especially for areas south of port aransas.

Increasing moisture and weakening upper geopotential heights will
contribute to isolated scattered convection during the period,
with the greatest probability Friday Saturday owing to greater
moisture proximity of a surface trough. Persistent onshore flow
during the period, owing to a surface ridge over the NRN gulf of
mexico surface low over west texas Monday Tuesday, and due to the
proximity of the surface trough higher surface pressure to to the
n NE afterward.

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.
