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.

Please see the 12z aviation forecast discussion below.
Vfr conditions will continue at area TAF sites through the current
forecast period. Only high clouds are expected today as light and
variable winds this morning transition to a more east to
southeasterly direction this afternoon.

short term (today through Thursday)...
we'll see a continuation of mostly uneventful weather with dry air
and near to just below seasonal normal temperatures through tonight.
A weak mid level low hangs up in light steering flow aloft and
remains nearly stationary over NRN mexico for the next day and begins
lifting NE toward ok Thursday. Light easterly surface winds are
sustained through tonight to keep the temperature trends flat through
Thursday. Southerly winds developing toward Thursday morning will
show a minimal impact on overnight dewpoints, leading to a warming
trend on min temps that will be only a degree or three over the lows
of this morning. Increasing moisture and some mid level clouds
spilling into our western and central counties should curb high temps
for Thursday afternoon.
Long term (Thursday night through Tuesday)...
rising dewpoints will have mixed out leveled off somewhat for late
Thursday afternoon, leading to a rapid rise in low level moisture by
late Thursday evening. Given that nighttime winds may still decouple
some, a few areas may see min temps around midnight with a steady or
slow warming trend early Friday morning. Patchy fog is suggested for
central and eastern counties per MOS guidances, but am less eager to
add fog in some of the higher terrain areas where the higher wind
speeds overnight could generate light rain showers or perhaps
A comparison of the deterministic model qpfs over multiple runs
suggest a solid low cloud layer and little or no chance for deeper
convection for Friday into Friday evening. A few solutions depict
some more concentrated QPF over the hill country Saturday morning as
the weak front reaches central tx. Model trends continue slowing the
front and show a light wind field ahead of the front in part due to
some coastal troughing to the SE and a flattening with each run in
regards to the upper trough. This has translated to a decreasing
trend of QPF for daytime Saturday with higher amounts backing up into
n-central tx and along the upper coast. Then, Saturday evening,
model consensus brings a more aggressive frontal surge with
developing subsidence aloft further hindering Saturday night rain
chances. Similar to the past trough and cold front, chances for
deeper convection this weekend look increasingly bleak with each new
set of model runs.
The cold front has trended much weaker over the past several runs,
so highs Sunday may wind up being the same or warmer that on Saturday
due to the increased sunshine. Near normal temps are forecast in a
mostly zonal flow pattern aloft through Tuesday with temps and
dewpoints surging high Tuesday night. A higher amplitude trough is
forecast to take shape over the NRN us next Wednesday, signaling the
potential for more freezing temps possible late next week.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
