You might have wondered -- as you gazed out your sunny window and listened to news of record cold and snow sweeping the midwest and East coast -- is there a connection?
Yes, there is.
"Our weather often is the just the opposite of what it is in the eastern part of the united states," says Cliff Mass, professor of Atmospheric Sciences at the University of Washington.
"When we are cold, like it was just before Thanksgiving, they tend to be warm," says Mass.
The reason we're yin when they're yang, and vice versa, has to do with the jet stream and "ridges" of high and low pressure in the sky, as Mass explains it.
