Quiet, not stormy, weather for US this year so far
After a couple years of wild, deadly and costly weather, the United States is mostly getting a lucky break this year. So far.
Hurricane and tornado activity in 2013 has been flirting with record low levels, while heat waves are fewer and milder than last year.
Meteorologists credit a combination of luck, shifts in the high-altitude jet stream, and African winds and dust.
