vfr skies will continue through the evening hours at all TAF sites.
We will see continued south to southeasterly winds along the i-35
corridor through the period, with southeast to easterly winds at kdrt.
Low cloud development is forecast once again overnight around 08z.
We have gone with prevailing MVFR CIGS at ksat and kssf, but with
only a tempo group at kaus. Kdrt should remainVFR through the
entire time. Improving conditions will begin after 15z as low clouds
lift and scatter back toVFR cigs.

short term (tonight through Sunday night)...
elevated heat indices remain the short-term concern with most areas
seeing values approaching the lower end of heat advisory conditions.
A look at 24 hour comparisons would suggest not enough areas are
expected to reach our lower end threshhold of 108 to warrant new
product and will maintain the sps through early this evening. There
is still a chance that the Sunday morning assessment will warrant a
heat advisory for a part of the area, but will want to defer to the
early morning shift to make that decision.
Long term (Monday through Saturday)...
the h5 level ridge axis is overhead Sunday night but shifts NW to w
tx and into the red river valley by Monday evening. The h7 winds
become more sely and precipitable water should begin to rebound. This|
could allow temperatures to begin the gradually ease up while the
heat indices remain elevated Monday into Tuesday. A few afternoon
showers and thunderstorms could begin moving into the far southeast
counties as early as Monday with an isolated cell or two getting
close to the i-35 corridor by Tuesday afternoon. The h5 ridge axis
remains shifted west Wednesday but continues to extend an eastward
extention into north central tx and keeps most of south central tx
stable. An area of pooled higher precipitable water values over srn
la shown in the GFS is also confirmed with mid-level mesoscale
vortiticity pattern in both the GFS and ecm for Wednesday into
Thursday, but neither model is able to bring it west into the deeper
portion of the ridge over central tx. The overall shape of the ridge
would suggest some weakening toward the latter part of next week, but
deterministic models are to chaotic with the pattern for us to choose
the blended guidances with continued above normal temperatures and
rain chances mainly rooted over the coastal prairies.

The information on this web site has not been checked for accuracy. It is for entertainment purposes only and should be independently verified before using for any other reason. 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.
