La Nina Returning; 2nd Warmest Summer On Record For U.S.

La Nina is returning, and will continue through this coming winter season. See the story below:

For south central and southeast Wisconsin, this may bring increased chances for below normal temperatures and above normal precipitation (and snowfall). However, the correlation between La Nina and winter temperatures and precipitation in south central and southeast Wisconsin is not as robust as it is with El Nino.

The latest long range temperature forecasts from the Climate Prediction Center suggest equal chances for above, near and below normal temperatures for south central and southeast Wisconsin for meteorological winter (December 2011, January and February 2012):

The latest long range precipitation forecast from the Climate Prediction Center suggest increased chances for above normal precipitation for southeast and parts of south central Wisconsin for meteorological winter, with equal chances for above, near and below normal precipitation elsewhere across the area:
