Damn that's cold. Saw KBOI at M40 a few weeks ago when a nice area of cold air was moving in across the area. I don't know how people can live in such cold places.

The National Weather Service in Portland/Gray, Maine, said an unusual phenomenon for its area of responsibility is possible Friday night as the tropopause – the boundary between the troposphere, where our weather occurs, and the stratosphere, the layer of the atmosphere above the troposphere – could dip below the peak of Mount Washington.
