According to the weather boys at the National Oceanic and Atmospheric Administration (NOAA), there is increasing confidence that La Nina conditions are weakening and that neutral conditions between La Nina and La Nino will prevail by this summer.
Even if that’s correct, La Nina will have plenty to say about conditions in the meantime. According to NOAA, “Expected La Niña impacts during March-May 2011…in the U.S. include an enhanced chance of below-average precipitation across much of the southern states and the Central Rockies and Central Plains. An increased chance of below-average temperatures is predicted for much of the West Coast and across the northern tier of states (excluding New England). A higher possibility of above-average temperatures is favored for much of the southern half of the contiguous U.S.
