The Weather Channel has issued its winter forecast for 2014-2015, and it looks a bit different from last winter.
Compared to 2013-14, which was one of the coldest winters in recent memory in the Upper Midwest, this winter the chill looks to be more focused on the East Coast and Gulf Coast, according to the winter forecast prepared by WSI, which along with The Weather Channel is part of The Weather Company.
The forecast, which looks ahead to temperatures from Dec. 1, 2014 through Feb. 28, 2015, is based on an analysis of several large-scale factors in the land-ocean-atmosphere system.
One factor is, as you might expect, the presence or absence of El Nino -- an area of warmer-than-average water in the eastern Pacific Ocean near the equator.
While El Nino has not developed yet, WSI forecasters expect a weak to moderate El Nino to emerge over the winter months and potentially persist into the spring.
