Warmer Weather Coming to the U.S.

Thank you, weather gods. After a brutal winter, warmer temperatures are finally coming to the United States. An El Niño watch was issued Thursday, with one expected to hit by this summer. Its arrival means fewer Atlantic hurricanes and a milder winter for the north next year. But it also augurs a hot year coming up. El Niños arrive every few years, shaking up the global climate patterns.
