short term (today through Friday)...

other than few to scattered upper level cirrus clouds across the
eastern counties early this morning, expect dry and hot weather
conditions as the day progresses. Chances for rain are confined to
areas along and east of highway 77 as tropical storm cindy makes
landfall near the louisiana-texas border later this morning. Dry
weather conditions are anticipated later this evening into Friday as
moisture associated with cindy pushes to the northeast and away from
south central texas.

Today's high temperatures are forecast to reach the upper 90s across
much areas and up to 104 over parts of the rio grande plains. Heat
indices are expected to range from 100 to 106 mid-afternoon through 6
pm.

Southerly flow returns this evening as cindy circulation moves to the
northeast. This translate into higher temperature dewpoints and
warmer temperatures on Friday morning. This trend continues
throughout the day on Friday with high temperatures expected to
reach the 100 degree mark for much of the area with upper 90s across
the hill country. Heat indices are anticipated to range from 104 to
110 degrees in the afternoon period. If this trend continues, a heat
advisory will likely be issued for Friday afternoon during the
overnight weather package on Friday.

Long term (Friday night through Wednesday)...

chances of rain will be increasing over the weekend into early next
week as several outflow boundaries are expected to push from west
texas into our area and combine with a weak frontal boundary and
remnant moisture of cindy. Medium-range models are having
difficulties handling the position of the weak frontal system and the
strength of the subtropical upper level ridge across the desert
southwest. However, later in the week, the subtropical ridge is
expected to further push to the east and into our area to mark the
end of rain chances across south central texas.

Will get a bit of a break from the upper 90s and near 100 degree days
over the weekend through early next week due to cloud coverage and
chances of rain.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
