What's New / NOTES
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Cigs vary fromVFR to ifr this morning. We think they will settle at
MVFR across the region within the next hour or two. The should
rebound toVFR by around noon at all area airports. Showers and
thunderstorms are possible this afternoon and early evening. Most
likely time looks like between 18z and 22z in austin and san antonio.

Chances are lower at drt. CIGS should stayVFR overnight.

short term (today through Tuesday)...

a moist southeasterly lower level flow was across south central texas
early this morning with pws little changed from this past weekend and
ranging from 1.5 inches edwards plateau to 2 inches east of i-35 to
the coastal plains. This is feeding a band of showers in a convergent
zone from the middle texas coast into central texas. Other showers
are trying to develop over the edwards plateau to rio grande plains.

Meanwhile, a linear MCS is moving across the permian basin. Showers
will continue to develop this morning from the coastal plains into
central texas in this flow, and over the hill country due to upslope
flow there. As heating destabilizes the airmass and with surface
boundary collisions, thunderstorms will also develop. After sunset
with loss of heating, showers and thunderstorms will tend to wane.

However, the MCV or its remnant surface boundary generated by the
permian basin MCS will likely be approaching the edwards plateau.

This should be enough to keep showers and thunderstorms going or
redeveloping over the hill country and edwards plateau this evening
into the overnight. Later tonight into morning, streamer showers are
expected again moving further inland from the coastal plains. Little
change in airmass is indicated on Tuesday with a similar pattern to
today. However, the mcv, possible mid level shear axis, may enhance
shower and thunderstorm development. The main threat in the short
term remains locally heavy rains that may cause some minor flooding.

Some minor stream flows or rises were noted from locally heavy rains
this weekend. Cannot rule out wind gusts to 30 mph with the stronger
storms. Temperatures continue below normal due to clouds and rain.

Long term (Tuesday night through Sunday)...

subtle changes take place mid to late week as the subtropical ridge
weakly builds into our area with a mid level shear axis along or just
off the texas coast. The moist airmass shifts to the east with lower
pws, near 1 inch, moving into the edwards and the 1.5 to 2 inch
range shifting to the i-35 corridor to coastal plains closer to the
mid level shear axis. Chances of showers and thunderstorms continue
for the central and eastern parts of south central texas with most
activity during the early morning to evening hours and enhanced by
the seabreeze. Most models build the subtropical ridge a little more
over our area next weekend, effectively ending the rain chances.

However, the ECMWF show the shear axis moving west across southern
texas maintaining at least slight rain chances. For now, the forecast
has followed the model consensus. A very slow warming trend develops
Wednesday and continues through Friday, then more stable
temperatures next weekend.

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.
