Long Range Temperature Outlook Autumn-Winter 2010-2011

The long range outlook for October, November and December 2010 (OND 2010 on the map) is a forecast of a continuation of above normal temperatures for much of the Conterminous 48 states, including Nebraska.

The Climate Prediction Center is forecasting that a La Nina will be developing this Autumn into the upcoming Winter. La Ninas typically bring Winters of strong contrasts in the Great Plains and Midwest with large swings from warmer than normal temperatures to outbreaks of bitter cold Arctic air. The second outlook map, January, February and March 2011 (JFM 2011 on the map) has a forecast of colder than normal temperatures for the Pacific Northwest and across the far northern Great Plains. Nebraska is in a region of "EC" which means equal chances of it being Above Normal, Normal or Below Normal.
