U.S. weather can often be like a seesaw: when temperatures rise on one end they fall on the other side.
That’s the case now, with an Arctic chill that grips New York and the Northeast pushing temperatures well below freezing while California is dry and mild. It’s a turnabout from December, when the eastern U.S. enjoyed almost spring-like conditions with record-high temperatures and outbreaks of tornadoes, while California and the Rocky Mountains were buried in snow.
