"The jet stream has been flung all the way north across central and eastern Canada," AccuWeather.com Expert Senior Meteorologist Alex Sosnowski said, when explaining why warmth has been so widespread this March.
"At least two-thirds of the nation could wind up with above-normal temperatures [this spring]," Paul Pastelok, expert long-range meteorologist and leader of the AccuWeather.com Long-Range Forecasting Team, said late in February. He forecast that there could be the most widespread warmth this spring since 2004.
The warmth and humidity have been fueling an active start to the severe weather season, including rare tornadoes as far north as southern Michigan.
