Short term (tonight through Tuesday night)
The main concern in the near term will be monitoring a retreating
frontal boundary for possible convection this afternoon and evening.

Chances are fairly low, but we have included a slight chance for
areas along and north of a lexington to burnet to fredericksburg
line. Any convection that develops is expected to decrease with the
loss of daytime heating. For the overnight hours, south to
southeasterly flow in the low-levels will increase, bringing an
increase in moisture to all areas. Some models show some light
showers developing overnight across the coastal plains and hill
country areas. We will leave this out of the forecast for now as
overall confidence is low. Attention will then turn to an upper level
trough set to impact the region beginning Tuesday afternoon. Several
hi-res models show potential for convection to break out during the
late afternoon hours across the rio grande plains, southern edwards
plateau and hill country. If convection does manage to develop,
storms would likely become severe fairly quickly given good cape
values along with adequate vertical wind shear. By early evening,
the dryline located across west central texas is expected to become
increasingly active. As dryline storms propagate eastward,
thunderstorm chances will be on the increase for areas along and west
of i-35 during the overnight hours. Some of the hi-res models show
the line of storms could weaken as they approach the i-35 corridor.

I'm not completely sold on this solution as we should still have some
good lift across the region with the upper low to our west.

Long term (Wednesday through Monday)
Early Wednesday morning, we expect showers and thunderstorms to be
ongoing across much of the hill country and i-35 corridor. For the
afternoon hours, convection should move east of the i-35 corridor as
the cold front shifts east. We will need to monitor the front during
the afternoon hours on Wednesday as this may provide a focus for
convection. The upper level trough axis moves east of our region
Thursday afternoon as dry, northwest winds spread over the area. Dry
weather continues on Friday, but southerly winds will quickly return
to the area ahead of the next upper level system. There is some
disagreement among the extended models with regards to the timing of
the next upper trough. The ECMWF remains faster and shows a more open
wave, while the GFS and canadian show more of a closed upper low. We
will continue to monitor and for now will show rain chances for most
areas Saturday through Monday.

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.
