Short term (tonight through Saturday night)
Hot and humid conditions continue across south central texas this
afternoon. Given recent observations and short term model guidance,
the current heat advisory is in good shape and will continue until 8
pm. Southeast winds remain intact this evening and cooling after
sunset will be rather slow given plenty of low-level moisture in
place. Rain chances for tonight will remain low and generally
confined to areas north of a del rio to austin to la grange line. The
hi-res models continue to show convection developing across west
central texas this evening, with some of this activity possibly
reaching the southern edwards plateau and western hill country around
or shortly after midnight. This convection is expected to weaken as
it moves southward into our region. Elsewhere, the hi-res models also
show convection developing across north texas early Saturday morning
as a cold front moves southward. We should see enough convection to
help usher the cold front southward during the morning hours on
Saturday. The front will likely halt it's southward progress during
the afternoon and should remain north of the highway 90 corridor.

However, we should see enough convergence along the front and outflow
boundaries to initiate scattered shower and thunderstorm development
on Saturday. Temperatures will cool given the expected increase in
cloud cover and precipitation. However, areas south of the front
could still see highs in the mid 90s to near 100.

Long term (Sunday through Friday)
A reinforcing shot of high pressure moving into oklahoma and
arkansas early Sunday morning should be enough to help the front
slide a little farther southward on Sunday. We should continue to see
a chance for scattered showers and thunderstorms, with better coverage
in the afternoon and evening during peak heating. As we head into
early next week, the frontal boundary will continue to weaken and
become ill-defined. A fairly active northwest flow aloft is still
expected to continue into early next week and we'll continue a
chance for showers and storms across south central texas. We should
see enough influence from a subtropical ridge building in from the
west toward the middle of the upcoming week for a return of warm
temperatures and dry weather for most areas. We can't rule out some
sea breeze convection near the coastal plains and highway 77 corridor
and will mention a low chance in the forecast.

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.
