Short term (tonight through Wednesday night)
For the next few hours, the main area of concern will remain out west
along the rio grande and southern edwards plateau. Currently, we are
beginning to see the low clouds erode across the rio grande plains.

Several hi-res models suggest development is possible along this
differential heating zone and this area will need to be monitored
carefully through this afternoon. For the early evening hours, the
pacific cold front will overtake the dryline across west central
texas, including the edwards plateau. As this occurs, convection
should quickly develop, then progress eastward into the rio grande
plains, southern edwards plateau and western hill country between 9
and 11 pm. For the overnight hours, this line will move eastward and
impact the remainder of the hill country and i-35 corridor between
midnight and 6 am. We continue to expect damaging winds and large
hail to be the main severe weather concern for tonight as this line
of storms moves through the area. However, we can't rule out an
isolated tornado as well. As the line shifts east of the i-35
corridor after 6 am, most models indicate a weakening trend as this
line of convection moves east of the strongest upper level lift.

However, we will still need to monitor this line of storms carefully
as it will be moving into favorable moisture and low-level wind
shear. Given the speed of this system, the risk for heavy rainfall
appears rather low at this time. Storm total amounts will likely be
lowest (1/4 inch or less) along the rio grande, with amounts
increasing to 1/2 - 1 inch for areas north of a kerrville to cuero
line. Some spots could pick up around 1.5 inches north of this line,
but these amounts should be isolated. Areas east of i-35 can expect a
low chance of rain Wednesday afternoon, with the remainder of the
area remaining dry.

Long term (Thursday through Tuesday)
A relatively quiet weather pattern is in store Thursday and Friday
and this will lead to a dry forecast along with above normal
temperatures. The pattern is expected to once again become
increasingly active for the upcoming weekend into early next week as
another upper level storm system takes aim at the region. The medium
range models are starting to show a little better agreement with
regards to the mid-level flow pattern. This system should come across
texas at a lower latitude and this should bode well for a good chance
of rainfall and active weather across south central texas, especially
Saturday night and Sunday. This upper system moves to our east by
late Monday, temporarily leaving a dry forecast into Tuesday.

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.
