Despite heavy, flooding-producing rains at the beginning of October, 99% of Texas remains under severe drought conditions, Think Progress reports (and kudos to them for continuing to stay on top of this one). Check out the drought map (below) from Drought.gov to see the overwhelming and continued extent of the record-breaking dry conditions gripping the state:
As for why the rains of a couple weeks ago didn't much help to alleviate the situation, the intensity of the rain is important. Several cities actually set new daily records for rainfall: Waco (5.83"), Houston (5.11"), Dallas (1.37"). In such dry conditions, especially, that much rain just causes flooding and runs-off.
Several weeks ago the National Weather Service said there was no end in sight for the Texas drought; and here's the kicker quote from climatologist John Nielsen-Gammon on the potential durations of all this:

The move prompted the scientists producing the report to demand their names be taken off it.
