The Climate Prediction Center (CPC) announced Thursday that La Niña has returned. Below-average water temperatures were reported along the equator in the central and eastern Pacific Ocean, allowing for the CPC to upgrade the La Niña Watch to a La Niña Advisory.
A La Niña weather pattern usually means a drier and warmer weather pattern than normal for Texas. The cooler-than-normal waters along the equator in the Pacific Ocean allows for the jet stream to build farther north of Texas, limiting the frequency of the storm track to bring Texas rain and cold air in the fall and winter months.
The 8- to 14-day outlook, which takes us to Thanksgiving Day, shows above-average temperatures and below-average rainfall. The three-month (November, December, January) seasonal outlook also calls for warmer-than-average and drier-than-average conditions.
According to the CPC, there is a 65 to 75 percent chance that La Niña conditions continue through at least the winter months.
