Andover, MA , Sept 20, 2011 - The Weather Channel, based on a forecast powered by WSI (Weather Services International), expects the upcoming fall period (October-December) to average cooler than normal in all of the northern and eastern US, with above-normal temperatures confined to the southwestern US.
On The Weather Channel : Can Seasonal Outlooks Help the Economy?
"The primary ocean signals suggest the late fall and early winter period will resemble those of the last three years, with an early start to winter in the eastern US. While October should be relatively mild across much of the US, below-normal temperatures will become more common in the eastern US in November and across all of the northern US by December," said Dr. Todd Crawford, the chief meteorologist at WSI, a sister company to The Weather Channel. "The combination of the newly-emerging La Nina event and the continued trend towards North Atlantic atmospheric blocking support both support this hypothesis."
In December, The Weather Channel and WSI forecast:
Northeast - Colder than normal
Southeast - Colder than normal, except FL
N Central - Colder than normal
S Central - Colder than normal, except TX
Northwes - Colder than normal
Southwest - Warmer than normal
