Aviation
Scattered to numerous shra tsra continued across the hill country,
central texas, and the austin area. These will gradually push to the
e SE across the remainder of south central texas as a surface trough
currently developing between san antonio and del rio shifts e. Have
gone with tsra at kaus to start the TAF period, tempo at kdrt for
00z-02z, and ksat kssf for 02z-06z. After that chances are uncertain
as surface trough focuses best chances southeast of i-35.VFR cigs
will prevail, except brief MVFR CIGS vsbys in shra tsra. Some areas
of MVFR ifr CIGS may develop overnight into Monday morning. CIGS will
lift toVFR midday on Monday. Wind gusts up to 60 kts and gr gs are
possible in the strongest tsra, otherwise winds will be 10 kts or
less.

short term (tonight through Monday night)...

upper air analysis this morning showed west-southwesterly flow over
tx with a trough from central canada to the four corners. At the
surface, a cold front was moving into our northwestern counties.

Winds ahead of the front were from the east to southeast and dewpoint
temperatures were in the lower to middle 70s. The upper level trough
will move across tx during this period. With the upper flow nearly
parallel to the front, it will move slowly through the area tonight
and Monday. This will mean showers and thunderstorms will be likely
tonight and Monday. At the start of the period, model soundings show
cape around 4000 j kg, but with 0-6 km wind shear only 20-30 kts.

This could produce strong to severe thunderstorms with large hail as
the mostly likely threat this evening. Atmosphere is fairly uniform
across the cwa, so where storms are worst will depend on how things
develop with small scale features that are not well resolved now.

Storms should weaken below severe strength by midnight. Expect
convection to continue overnight and during the day Monday. Monday
night chances will decrease with slight to low chance pops.

Long term (Tuesday through Sunday)...

the pattern will remain unsettled through the week with west-
southwesterly flow aloft. A series of short wave troughs will move
through the pattern bringing chances for convection. Wednesday night
and Thursday a stronger short wave will bring a better chance for
showers and thunderstorms and some higher rainfall totals. The
overall pattern will change little toward the end of the period and
low chances for convection will remain in the forecast until the end
of 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.
