Pressure patterns could portend heat waves
Signals in atmosphere may help scientists forecast temperature hikes 15 to 20 days out

High-pressure patterns in the atmosphere could allow scientists to predict U.S. heat waves five to 10 days sooner than is currently possible with traditional methods.
Right now, scientists can forecast a heat wave about 10 days before it hits. Haiyan Teng of the National Center for Atmospheric Research in Boulder, Colo., and colleagues suggest that an atmospheric pattern of five high-pressure systems spanning the Northern Hemisphere could signal a heat wave is on its way in 15 to 20 days.
