Booyah!! Here is what NOAA is saying about the possibility of another La Niña winter in 2011/12:

Combined with the recent weakening of the positive subsurface ocean anomalies and the lingering La Niña state of the atmosphere, the possibility of a return to La Niña during the Northern Hemisphere fall 2011 has increased over the past month.”
