Normally quiet and reserved WeatherBell senior forecaster Joe D’Aleo (co-founder of the Weather Channel with John Coleman) almost never writes (email subject lines) like this. When he does, it gets my attention. A new forecast shows the cold blast in the eastern half of the USA extending well past Groundhog Day, Feb 2nd, according to their models. WeatherBell has had an excellent track record this winter so far. He says he hasn’t seen anything like it since 1918 when the big flu pandemic hit the USA.
