New 30-year climate normals

Oregon State University’s new maps of 30-year U.S. climate “normals” show the area east of the Rockies is getting wetter, the Southwest is getting drier, and temperatures are inching upward – with daily lows rising faster than daily highs.

“When we publish the new normals every 10 years, we’re taking away one decade from a 30- year period and adding another, which means the changes we see are subtle,” said Chris Daly, professor of geospatial climatology and the founding director of Oregon State’s PRISM Climate Group.
