Marine Weather and Tides
Palacios, 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]
Current radar imagery shows scattered thunderstorms further
inland this afternoon from burleson east into walker county, while
remnant showers remain situated further south to along the coast.

Occasionally, an isolated shower or thunderstorm has developed
over the gulf waters before pushing inland, and expect this trend
to continue into the evening. Overall motion of the precipitation
is towards the northwest. A consensus of the short term model
guidance hints at most of the precipitation dissipating shortly
after sunset. The upper-level disturbance that has remained
situated over southeast texas today will translate eastward
through the overnight hours. Winds will become light and variable
tonight as a region of surface high pressure builds in. Upper-
level ridging will also shift east into central texas Thursday
morning. This will help to lower precipitable water values (pws)
Thursday and into the beginning of the weekend, with pws falling
to between 1.4-1.6 inches. This will allow for less overall
coverage of showers and thunderstorms for the remainder of the
week, though the chance for precipitation will still be possible.

Long term [Saturday through Wednesday]
The main weather threat heading into the weekend will be
abnormally warm conditions. The upper-level ridge that nudges
into the region earlier in the week will push overhead into the
weekend. Therefore, as we move into the holiday weekend, conditions
will become very warm for this time of year. Relative humidity
values should reach into the 90s and high temperatures are
forecast to be in the mid to upper 90s. Sunday apparent temperatures
should range between 98-103 degrees. The apparent temperature or
"heat index" is defined as an approximation of how hot it "feels"
for a given combination of air temperature and relative humidity.

Expecting apparent temperatures to remain high between 98-103
degrees through the middle of next week. As a result, these
unseasonable warm conditions will flirt with record high
temperatures. Record high maximum temperatures for this weekend
are listed in the climate section below.

Marine
Light to moderate southerly winds along with low seas will continue
through the end of the week. Light southwest to west winds are
anticipated over the weekend. Showers and thunderstorms will
continue to be possible. Boaters with interests in the central and
eastern gulf of mexico should monitor the forecasts for possible
storm formation at the end of the week or over the weekend. 42

Climate
Abnormally warm weather will flirt with record high temperatures

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.
