La Nina is weakening, but that is what it does in the spring and summer months. Will it be back for the winter? Some are thinking that it will. The big question is will another dome of high pressure form over West Texas, Mexico, AZ, and NM like it did last spring/summer?
I am not sure where in Texas you are Sue, but from research that I did last fall, the DFW area's water problems were due to human mismanagement as well as lack of rain. DFW was more than 18 inches short of normal going into Jan 2012 and that area has not be effected as severely as the rest of the state.
