Marine Weather and Tides
Sunset Valley, TX

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Short term (tonight through Friday night)
The weather is mostly quiet across south-central texas at the present
hour. Temperatures are in the middle 80s to middle 90s with several
more hours of heating still in store for today. Skies are partly
cloudy with some afternoon cumulus with only a few showers so far in
the extreme southeastern cwa. Any additional shower or storm activity
this afternoon should remain confined there. Most or if not all
remaining activity should be over by 00z and will not mention any
precip in the forecast for the evening hours. Any activity in west
texas should also remain out of the CWA and will not mention anything
in our western counties. Evening shift will monitor and update as
necessary. There could be some more patchy fog for the southeast
counties by morning, but not expecting it to reach as far north as
previous nights.

For tomorrow, isolated shower activity will be even less than today
as the atmosphere continues to dry out as a ridge begins to build
east. Highs will top out in the lower 90s to upper 90s or about 2-3
degrees higher than today. Lows tonight and Friday night will be in
the upper 60s to lower 70s.

Long term (Saturday through Thursday)
The long-term forecast is expected to remain rain free across south-
central texas as high pressure continues to build into the area from
the west. This same high will ensure that the area of disturbed
weather and potential alberto will remain over the eastern gulf of
mexico this weekend and away from the western gulf. Highs through
Wednesday look to be in the upper 90s to 102 with the 100 degree
values in the western and southwestern cwa. The GFS then GOES kind of
bonkers with temperatures Wednesday and Thursday with its raw model
output Thursday showing highs in the 100-109 range across much of
the CWA while the ECMWF still shows persistent temperatures in the
upper 90s to 102 range. In addition, low level flow is from the
south southeast which also does not fit the normal conceptual model
for a record breaking heat wave. We normally would need a down-
sloping W SW wind to promote compressional warming. For the official
forecast will show highs Wednesday and Thursday remaining in that
upper 90s to 102 range with lows throughout the long-term forecast in
the 70s for much of the region. Heat index values will remain below
105 over the next 7 days with afternoon dewpoints remaining below 70
degrees.

GOES Local Image of SouthCentralPlains    EDIT
NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

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.
