Aviation
Clouds are breaking over south central texas and partly cloudyVFR
skies are expected for the afternoon hours. Southeast winds will
continue through the afternoon around 10 knots across the i-35
corridor, but could gust to as high as 25 knots across the rio grande
plains. While an isolated shower is possible through the late
afternoon hours, chances are the terminals are low enough that they
do not warrant a mention in the tafs at this current time.

Will go with a persistence forecast for the next round of morning
stratus and take all of the i-35 sites fromVFR to MVFR to ifr
between the 07z and 09z hours. There will be slow improvement through
the morning withVFR CIGS returning by 17z Sunday. Drt will also see
a reduction in CIGS around 08z to MVFR levels for most of Sunday
morning. Winds at drt will pick back up Sunday afternoon gusting to
around 20 knots.

12z tafs
cigs are expected to be between MVFR and ifr categories along the
i-35 terminals for the next several hours before they lift toVFR
late this morning. Patchy to areas of fog have developed to the south
and east of the i-35 sites this morning and expected to lift within
the next couple of hours. Wind should stay from the southeast at 8 to
12 knots with gusts up to 25 knots along the rio grande. Isolated
showers and storms are expected east of the i-35 with no impact to
the area terminals.

short term (today through Sunday)...

early morning surface observations show plenty of low-level moisture
in place with dewpoint temperatures currently in the upper 60s and
lower 70s for most areas. Winds are also fairly light east of i-35
and this has allowed some patchy fog to develop. The fog will
continue through mid-morning, then dissipate quickly as daytime
heating and mixing commence. We will likely see a few showers early
this morning given plenty of moisture along with the presence of a
low-level jet. The texas tech WRF and hrrr models are consistent in
showing the better rain chances this morning along highway 83. For
the afternoon hours, look for high temperatures near climatological
normals along with a low chance for showers and thunderstorms. Any
showers and storms should dissipate fairly quickly with the loss of
daytime heating. The one exception to this could be out west along
the rio grande where some convection across the lower trans-pecos may
impact western val verde county. The weather pattern will change
little on Sunday and we should see another round of mainly isolated
afternoon convection across the region along with near normal
temperatures.

Long term (Sunday night through Friday)...

early next week, a broad upper trough will gradually approach from
the west. Ahead of this trough, we will continue to see a strong
southeasterly flow in the low-levels and this will help maintain or
increase moisture levels across the region. In the mid and upper
levels, we will continue to see an increasingly active southwest
flow as an upper trough remains to our west. In addition, a cold
front will move in either late Tuesday or Wednesday. The GFS and
ecmwf are beginning to show some agreement with regards to timing,
with the GFS trending toward the faster ECMWF solution with the
front. The cold front is expected to slow it's southward progress or
perhaps even stall over the region Wednesday or Wednesday night.

This pattern still remains favorable for a heavy rainfall event
across portions of south central texas. At this time, it appears
areas along the rio grande and southern edwards plateau will see the
heaviest rainfall totals late Tuesday and Wednesday. However, the
potential for heavy rainfall could persist well into Thursday. Model
qpf amounts are quite impressive along the rio grande. While these
totals are likely too high, am still concerned about the heavy
rainfall and flooding threat along the rio grande and southern
edwards plateau during the middle of the upcoming week. The gfs
ensemble plumes along with MOS guidance numbers continue to show
good confidence for some heavy rainfall and we will continue to
mention this in the hazardous weather outlook. For the remainder of
south central texas, we do expect a decent chance of rain, but should
see lesser amounts as the main source of lift should remain focused
along the rio grande.

Some drier air is expected to move in behind the front on Friday and
we will see decreasing rain chances.

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.
