Effects of La Niña on Tahoe/Truckee Snow Uncertain for Upcoming Winter

While other parts of the United States may be in for some extreme temperatures this winter due to La Niña weather patterns, the effects on Tahoe are uncertain.

La Niña is associated with cooler-than-normal water temperatures in the Equatorial Pacific Ocean and can bring extreme temperatures and precipitation.

While the National Oceanic and Atmospheric Administration reports the Northwest may experience a wetter and colder winter than normal, and the Southwest and South may experience a drier and warmer winter than normal, Lake Tahoe falls into the “equal chances” category.

Lake Tahoe has a 33 percent chance of receiving more perception that normal, a 33 percent chance of average precipitation and a 33 percent chance of having less than average perception. As for temperature, the region has a 33 percent chance of warmer than usual weather, a 33 percent chance of average temperature and 33 percent chance of colder temperatures.

In other words, Tahoe's in no man's land when it comes to long-term forecasting, said Jan Null, a certified consulting meteorologist with Golden Gate Weather Services.

“It's a non-forecast,” Null said.

Last year the country experienced an El Niño, which is associated with warmer than normal water temperatures.
