December 1989, ranks as one of the most historic months with regard to
temperatures across much of the eastern half of the country. Locally,
it was one of the coldest months on record...and coincidentally was
followed by one of the warmest January's on record.
In recognition of the 20th Anniversary of this amazing feat by Mother
Nature, Forecasters Pete Banacos, Brooke Taber and Eric Evenson have
put together an excellent in-depth analysis of the atmospheric patterns
responsible and the resulting temperatures observed in the region. I
thought you folks may find it interesting as well.
