Last week’s Arctic outbreak brought some of the coldest air in decades across the U.S. Midwest and South. But interestingly, it didn’t last as long as historic cold waves of the late 20th century.

In parts of California and Oregon, 2013 was the driest calendar year on record, with no sign of relief on the horizon. NCAR scientists are examining how water and energy use intersect across this drought-prone region and how the nexus could evolve in a future climate.
