Forget the five-day forecast.
There's a forecast out for the next century.
And it's got some extreme predictions blamed on global warming.
A federal government study predicts more extended droughts, longer heat waves and heavy rainfalls.
And among the places researchers consider at particular risk is the western U.S.
The study's lead author says it's among the "hot spots" that will see the worst extremes, along with Brazil and Mediterranean countries.
She predicts "a wild ride."
Researchers say the West will be affected by changes caused by the world getting warmer.
But it's not all bad news.
The study also predicts fewer freezes and a longer growing season.
