Meridian Environmental Technology President Leon Osborne said that the possibility of an exceptionally cold winter is about 90 percent. He said it could be the coldest in the past 40 years.
Osborne said part of the reason for his forecast is a change in ocean currents that’s melting more north polar ice than usual. He said that has created an above-average amount of open water, which in turn affects the jet stream.
Osborne said another reason for the strong likelihood of a cold winter is La Nina, a weather phenomenon involving the cooling of tropical Pacific water.
