are showing the return of low clouds overnight in austin and san
antonio with MVFR CIGS developing around 09z and lasting until late
morning Sunday.

short term (today through Sunday)...

as an upper level low centered over far eastern oklahoma moves
further to the east, a weak cold front surging south has pushed off
the escarpment. It will exit to the southeast of our area by around
sunrise and cannot rule out an isolated shower or two along it near
the coastal plains. Surface high pressure briefly builds into our
area this morning maintaining a dry airmass, then moves off to the
east this afternoon into evening as an upper level trough over
coastal southern california approaches the four corners region
causing surface pressure falls in the southern plains. Southerly
winds return this evening into tonight with increasing lower level
moisture leading to stratus by Sunday morning. The upper level trough
moves out into the central and southern plains on Sunday with a
stronger pressure gradient causing some locally breezy winds and
mixing out the stratus by midday.

Long term (Sunday night through Friday)...

the upper level trough continues moving east across the plains.

Moisture convergence along and just east of the dryline may allow
for showers and thunderstorms across the eastern hill country to
along the i-35 corridor Sunday evening. However, a strong capping
inversion with dry air above will inhibit convective development and
only isolated coverage at the most is expected. Another strong upper
level low moves across the southern plains during the middle of the
next week. Upward forcing increases with isolated to scattered
showers and thunderstorms developing on Tuesday and becoming more
numerous Tuesday night into Wednesday. There is still a potential for
strong to severe storms and locally heavy rainfall with this system.

A recent trend in the gfs, has troughing hanging back until Thursday
into Thursday night while the ECMWF keeps the low intact moving
across Wednesday into Wednesday night. For now, have ended pops from
west to east Wednesday into Wednesday night with lingering slight
pops along the highway 77 corridor on Thursday. Fair weather is
expect on Friday. Other upper level systems are expected beyond this
forecast for next weekend into the following week with additional
rounds of showers and thunderstorms.

Fire weather...

periods of elevated fire weather conditions are expected for the next
several days with the greatest chances out west Sunday, Wednesday,
and Thursday.

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.
