Could Record-breaking Rainfall End California's Drought?

One of the wettest Decembers in state history has left behind about twice the amount of water considered normal for this time of year in the snow pack high up in the Sierras. So come spring, a lot of water should come down from the mountains into the reservoirs of drought-plagued Southern California. We get a progress report from Frank Gehrke, chief snow surveyor for the California Department of Water Resources, and from Bill Patzert, a climatologist at the Jet Propulsion Laboratory.
