Short term (today through Sunday)
Goes 16 IR imagery shows high clouds traveling from west to east
across the area while nighttime microphysics channel captures
low level moisture pushing to the north across the coastal plains
early this morning. Surface dewpoint depression values ranging from
0 to 3 degrees have been observed across the coastal plains and parts
of the southern counties of south central texas for the past few
hours. Area forecast soundings, rap13 visibility product and GFS lamp
guidance suggest for the formation of patchy fog along and east of
interstate 35 this morning. Fog should lift by 8 am most areas.

A nice warm up is expected this afternoon with partly to mostly cloudy
skies and highs in the upper 60s across the hill country and low to
mid 70s elsewhere.

A cold front is forecast to push across our area Sunday morning.

Scattered to numerous showers are expected mainly along and east of
highway 281 through the forecast period. Rainfall amounts could range
from few hundredths to three quarter of an inch. Can't rule out one
to two inches of rainfall over few places near the coastal plains.

Long term (Sunday night through Friday)
Shower activity continues Sunday night into Monday as the cold front
stalls across the coastal plains and meet up with a surface inverted
trough across the deep south. Precip comes to an end from west to
east late Monday morning into the afternoon as an upper level short
wave axis moves across the area and forces the coastal trough to push away
from our area. Tuesday looks relatively dry. By Wednesday, the
coastal trough manages to return to the middle texas coast while an
upper level short waves pushes from the southern plains into the
lower mississippi valley. Scattered showers are expected across the
eastern two-thirds of south central texas through this forecast
period. Isolated thunderstorms can't be rule out across the northeast
part of the hill country Wednesday afternoon ahead of the upper
level short wave axis, where better lift could be found.

Showers will be around Wednesday night mainly over area along and
east of highway 77. However, a dry forecast is anticipated for
Thursday thanksgiving day with highs in the 60s. Dry weather
conditions continue Friday into next weekend.

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.
