Marine Weather and Tides
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Short term (today through Sunday)
Continued influences of a stubborn hot air mass continue today and
tomorrow. Highs again right around 100 degrees for much of the i-35
corridor with heat indices ranging from 101-108. The higher end of
these values will be seen again in the southeast zones. Surface winds
are expected to remain southerly and southeasterly today as a surface
high is located over the louisiana coast.
Over the last couple days, isolated showers and storms have developed
despite all clear indications from cams and other short range models.
Again this morning the hi-res suite shows the area shower-less,
however GFS and ecwmf deterministic produce isolated showers again to
the northwest. Looking at forecast soundings across the area, parcels
will be struggling against a pretty dry column and an unfavorable
wind profile above 600 mb. As a result, still feel that a dry
forecast is the right call, but did include 10 pops along the
southeast and northwest zones for the afternoon.
Long term (Sunday night through Friday)
A pattern change looks to be on the horizon beginning mid week as a
tutt low traverses the gulf of mexico, moving west. This will bring
at first, welcome relief of 2-3 degrees in MAX t, then an uptick in
pop chances as the low pushes west of the cwa. This pattern has been
pretty consistently advertised now in mid range models.
The more notable feature comes late week as a frontal passage is
progged to push south and into texas Wednesday night through Friday.
At the moment, the 00z GFS deterministic solution is significantly
more dry than its ECMWF counterpart. With the ridge centered over
northern mexico, whatever convection occurs with the frontal passage
should be able to push far enough south to bring showers at least to|
the northern zones late Wednesday night into Thursday morning. The
question will be how far south? The GFS solution stalls the front
along our northeast border with hgx fwd but with 850 mb flow parallel
to the boundary, could result in some locally heavy rainfall.
Additionally, the nose of the 850 mb LLJ would intrude nicely into a
2+" pwat environment along the stalled boundary... So if this solution
comes to fruition, could result in some meaningful rain for the
northern i-35 corridor, perhaps extending as far south as williamson
Come Friday, gfs ECMWF canadian all develop some sort of tropical
disturbance off the yucatan and pushes it quickly north along the
mexican coastline, coming on shore just south of brownsville. If so,
this would put the southern half of the state under a very rich
moisture regime for next weekend, possibly leading to more heavy
rainfall chances. More to come on this with more model evolution.

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.
