Synopsis for the middle texas coastal waters.. A moderate to strong onshore flow will continue into early this afternoon over the gulf waters and linger over the bay waters south of port aransas through late afternoon. A weak to moderate onshore flow is expected tonight into Saturday. Higher moisture moving into the region Saturday will lead to a chance of showers and Thunderstorms. Rain chances will increase Sunday into early next week as moisture increases and an upper level trough moves across the area. A frontal boundary will move close to the waters on Monday, resulting in a weak easterly flow. Rain chances will gradually diminish through the middle of the week.

Discussion
The small craft advisory for the northern nearshore gulf waters
was allowed to expire as the winds have decreased enough and the
seas continue to subside.

18z aviation cycle discussion is below.

Aviation
Today...VFR. Winds continue to back towards the southeast around
15 knots with gusts upward of 25 knots. High confidence.

Tonight...VFR MVFR. We lose the gusts but keep the onshore flow
going around 10 knots. Plenty of low-level moisture to go around
so expecting an area of stratus to develop and move inland around
midnight or shortly after. Medium to high confidence.

Saturday...VFR. Morning stratus lifts and scatters out leaving a
broken deck of stratocu. Could see some late morning showers and
thunderstorms develop near the coast and push inland as the sea
breeze circulation gets going. Added a prob30 for -tsra at kcrp
at this time. Medium confidence.

Previous discussion issued 1147 am cdt Fri jun 23 2017
discussion...

a few updates this morning, mostly to our headline products. One
of the biggest concerns today is the dangerous heat index values
we expect, this time area-wide. With onshore flow prevailing today
afternoon temperatures may be tempered a bit from 24 hours, but
with warm gulf and bays temperatures our dew point readings should
be 4 to 7 degrees warmer than yesterday. Just plain oppressive out
today. Kleberg county was upgraded to an excessive heat warning
due to the fetch off baffin bay where dew point temperatures may
near 80 degrees during peak heating. We could see heat index
values in and around kingsville exceed 115 degrees, possibly push
close to 120 degrees, so very dangerous conditions expected. Heat
advisory for the remainder of south texas remains in place.

Upgraded the rip current risk to high with long period swells
still traversing the gulf waters. As the afternoon winds back more
southeasterly the strength of the wind waves will increase making
for rougher conditions. Also cancelled the coastal flood advisory
as tide levels are well below our 2.0' msl threshold and the
tidal departures are now less than a foot. Now there could be some
very isolated pockets of better wave run- up today with the long
period swells in place but area webcams so a lot of the beach
roads are passable.

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.
