Given the time of year, and our luck/history with these rain-making systems as of late, I am siding with the GFS.
Given that, I hope the GFS is wrong, and the ECMWF verifies!

.SHORT TERM (Tonight through Thursday Night)...
The subtropical ridge will continue to dominate over South Central
Texas during this period. This will mean mainly dry weather for most
of the region. Southerly to southeasterly low level flow will
continue to pump moisture in from the Gulf. There may be convective
development along the seabreeze Thursday and this may move up into
our southeastern counties. Temperatures will be above normal.
&&
.LONG TERM (Friday through Wednesday)...
The upper pattern will change very little over the rest of the week
and weekend. An upper level ridge will continue to dominate and this
will suppress any chance for rain. Temperatures will continue above
normal through this period. Next week models are beginning to show
some changes, bur are not in good agreement. Both the GFS and ECMWF
develop an easterly wave in the Gulf and move it toward Texas. The
ECMWF develops this feature into a significant rain producing system.
The GFS weakens it as it moves into Central Texas bringing much lower
precipitation amounts. Given that this is the day seven forecast and
we are in the middle of a very dry period, we have sided closer to
the GFS with lower POPs and QPF. We will see how these forecasts play
out.
