From 1979 to 2001, the Northern Hemisphere's jet stream moved northward on average at a rate of about 1.25 miles a year, according to the paper published Friday in the journal Geophysical Research Letters. The authors suspect global warming is the cause, but have yet to prove it.

That potentially means less rain in the already dry South and Southwest and more storms in the North. And it could also translate into more and stronger hurricanes since the jet stream suppresses their formation.
