If it makes any difference, the current weather patterns for the Southwestern U.S. have meteorologists stumped. The El Nino/La Nina factor isn't even predictable. This was supposed to be a very dry winter, not one with a lot of snow pack, which we got in a La Nina year. It became a La Nina despite neutral predicted conditions, and we still get moisture from the south Pacific.
Last summer was the hottest one I can remember. Odds of repeating it are declining.
La Nina conditions weakened quite a bit in March. We're expected to get 3 more months of La Nina and we could be heading into a completely neutral pattern for the summer, which really jacks up the weather patterns ... last year under El Nino-neutral conditions hurricanes were driven far south into Mexico and Central America. Who knows what happens in a La Nina-neutral pattern.
