A storm system brewing in the Rockies today might trigger an outbreak of deadly tornadoes in the nation's midsection on Friday, according to meteorologists. In case you missed it, read PopSci senior editor Seth Fletcher's piece about how tornadoes form — and how climate change may be making them worse.
The midwest already suffered plenty of severe weather this week, with 30 tornado reports and 12 deaths Tuesday night and into Wednesday. Is 2012 shaping up to be another 2011?
