Vfr ceilings will transition to MVFR between 08-12z at all terminals
with low level moisture advection from the gulf underway. Mid and
upper level moisture streaming in from the pacific is already
producing widespread bkn-ovc altostratus around fl200 and the
presence of these higher clouds may affect the coverage of the lower
MVFR stratus deck this morning, possibly resulting in more temporary
ceilings than prevailing. Due to low confidence in this scenario have
continued with prevailing MVFR in the tafs but amendments may be
needed later this morning based on trends. Otherwise, heating will
allow for ceilings to lift toVFR by midday with a possible return of
MVFR early Friday morning. South to southeast winds in the 6 to 12
knot range are expected through the period. Breaks in the clouds this
afternoon may encourage a few stronger wind gusts in the 15-20 knot
range.

Early morning water vapor imagery shows a mid-level weakness
rotating over the san antonio terminals this morning and this is
producing light shra south and west of Sat ssf. Aircraft soundings
out of Sat earlier this evening indicated saturation between
fl025-065 and expect at least some of this to reach the ground
through 09-10z as shra drifts towards the northeast. Increasing
moisture combined with daytime heating will allow for scattered tsra
to develop near the terminals this afternoon and persist into the
early evening hours.

For the extended aus Sat tafs... A disturbance arriving after 06z is
expected to result in shra spreading across the i-35 terminals early
Saturday morning.

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.
