short term (tonight through Wednesday night)...
a dry atmosphere continues to be in place across south-central texas
this afternoon with dewpoints in the 10-20 degree range. Temperatures
have warmed up into the 60s across much of the area and this is
leading to humidity values in the 15 to 20 percent range. Otherwise,
light winds continue with passing high clouds over the area. For
tonight, dry air, light winds, and mostly clear skies will allow
temperatures to drop into the 20s and 30s with another freeze
expected for the hill country and low-lying areas along the i-35
corridor. For tomorrow, light east northeast flow will continue and
highs will remain close to today's values, in the 60s across the
region. For tomorrow night, another night in the 30s is once again
Long term (Thursday through Tuesday)...
south flow will finally return Thursday as a shortwave approaches the
plains. This will allow for low-level moisture to begin to increase
and lows Thursday night will only be in the 40s to near 50 degrees.
As the low-level moisture increases, theta-e advection will lead to|
low chances of light rain showers for the eastern two-thirds of the
area Thursday night and Friday. On Friday afternoon, a large trough
axis will push the northern plains and this will send a cold front
south into the region Saturday afternoon. This front will keep the
chances for rain around and weak instability levels could lead to a
few thunderstorms as the front moves through in the afternoon hours.
There still remains differences between the gfs ECMWF on the
strength of the cold front. The ECMWF continues to be stronger with
the front and clears things out pretty quick while the GFS is a bit
weaker. The GFS has slightly trended towards the ECMWF and will
continue to favor that solution in the official forecast.
Temperatures on Sunday Monday will remain in the 60s with lows in the
30s and 40s. South flow should return Tuesday, leading to
temperatures being a few degrees warmer.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
