La Niña is expected to continue into Northern Hemisphere spring 2008.
Edited on Fri Dec-07-07 07:51 AM by Gman
La Niña reached moderate strength during November 2007, with below-average sea surface temperatures (SSTs) extending from 160E to the South American coast

The recent SST forecasts (dynamical and statistical models) for the Niño 3.4 region indicate a continuation of La Niña into Northern Hemisphere spring 2008 (Fig. 5). Over half of the models indicate a moderate-to-strong La Niña through February, followed by a gradual weakening thereafter. Current atmospheric and oceanic conditions and recent trends are consistent with the model forecasts.

For the contiguous United States, potential impacts include above-average precipitation in the Northern Rockies, the Pacific Northwest, the Ohio and Tennessee Valleys, and parts of the Great Lakes region. Below-average precipitation is expected across the South, particularly in the southwestern and southeastern states.

-------------------------------------

Looks like it's going to stay dry in the South until at least the spring. Everything's drying up here in South Texas. Please note this has nothing to do with greenhouse gas enhanced global warming, but it sure doesn't help the effects of greenhouse enhanced global warming.

1. There was a major drought in the SouthEast and West before La Nina conditions
La Nina will mean the pattern will continue for the winter months;
but GW will likely mean it continues beyond La Nina months
