Short term (today through Tuesday)
The cold front has moved east of the i-35 corridor and will continue
through the remainder of the southeast CWA before sunrise. Sunny
skies with dry northwest wind today. Elevated to near critical fire
weather conditions are expected today. Highs in the low to mid 60s
across the hill country and upper 60s to around 70 elsewhere. Clear
skies and light winds tonight should for a freeze tonight across the
hill country and some drainage areas near and east of i-35 north of
i-10. Highs rebound back into the low to mid 60s Tuesday under
mostly sunny skies.

Fire weather
A dry northwest flow is expected today. 20-foot wind speeds will be
10-15 mph. However a 20-30kt 925mb flow will be in place through
midday, before weakening late afternoon, and momentum transfer
downward should allow for some surface gusts to around 20-25 mph
late morning through early afternoon. Wind speeds will gradually
decrease late afternoon through early evening. A window will occur
early afternoon where wind gusts are still occurring and rh values
are beginning to bottom out in the teens along and west of i-35 and
i-37 and low to mid 20s east. Given the fuel dryness across the hill
country and western CWA and forecast fire danger map from tfs will
word fire weather conditions as near-critical along and west of i-35
and elevated elsewhere.

Long term (Tuesday night through Sunday)
An increase in moisture will take place across the region Thursday
and Thursday night as southeast flow resumes and strengthens. This
could lead to patchy drizzle and isolated showers Thursday night into
Friday morning. Better chances for showers will come Friday into
Friday night as moisture deepens and forcing strengthens with
approach of upper level trough. That trough is forecast to send a
cold front through the area Saturday.

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.
