Aviation 00z tafs
Vfr conditions will prevail through this evening with MVFR ceilings
developing around 05z for the san antonio terminals as a 25-35 knot
low level jet overrides the balcones escarpment. As was the case
last night, ssf appears to be on the southern edge of this deck and
current TAF may need to be amended to shorten the duration of MVFR
conditions as stratus straddles the san antonio metro. Lowered
ceilings are expected to spread into aus and drt closer to 10-12z
with all terminals returning toVFR 15-17z.
A few pre-dawn streamer showers associated with the low level jet may
reach the corridor between aus and Sat but have left the tafs dry for
now due to low confidence. However, did add a vcsh mention in for
the austin and san antonio terminals late Saturday morning as a few
showers are expected to develop once convective temperatures are
reached. Otherwise, gusty southeast winds in the 10-20 knot range
this evening should subside 02-04z as the surface pressure gradient

short term (tonight through Saturday night)...
isolated to scattered showers and thunderstorms continue this
afternoon for areas near the coastal plains. Deeper moisture along
with the sea breeze will favor rain chances for areas generally along
and east of the i-35 i-37 corridors through early evening. However,
we could see some isolated activity near i-35 and will keep a low
chance in the forecast through early evening. With the loss of
daytime heating, most activity is expected to decrease. For the
overnight hours, the strengthening low-level jet will promote the
development of a few streamer showers over the hill country, i-35
corridor and coastal plains. Overnight lows will remain well above
normal, given southerly flow in the low-levels. Most areas will
remain in the in the 70s, with a few readings in the upper 60s over
the hill country.
Little change in the overall pattern is anticipated on Saturday. We
could see some isolated to scattered showers and storms, mainly
during the afternoon hours for areas generally along and east of
highway 281. It will be warm again on Saturday, with highs generally
in the 90s. With humid conditions in place, afternoon heat index
values will rise to around 105 degrees along and east of i-35.
Long term (Sunday through Friday)... |
above normal temperatures will continue for Sunday into early next
week as a subtropical ridge axis anchored over the southeastern u.S.
Will extend westward into the eastern and southern portions of texas.
An upper level trough axis will pass to our north on Sunday, but will
likely not have an impact on our weather given the strength of the
upper level ridge. Temperatures through the middle of next week will
remain above normal with highs generally in the 90s and lows in the
upper 60s and 70s. We prefer to go with the warmer ECMWF guidance
numbers with respect to maximum and minimum temperatures. The upper
level ridge axis may weaken or re-center itself over the eastern gulf
of mexico as we head into the middle of the upcoming weak. This may
allow for deeper southerly flow in the mid-levels, which may bring a
slight uptick in precipitation chances. However, we prefer to keep
rain chances low at this time in case the subtropical ridge axis
remains stronger than anticipated.
For mid to late week, the medium range models continue to show an
upper low somewhere over the desert southwest or northern mexico. The
models do eventually lift this system into the southern u.S. Plains,
but at this time it is advertised to remain too far north to offer
a great opportunity for rainfall. However, given a slightly more
active flow aloft, we will keep low rain chances in the forecast for
most areas for the mid to late week period. As for temperatures, we
do not see much relief given a warm a humid air mass maintaining it's
grip across the region.

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.
