If there aren't any climate researchers looking into this now, I'm sure there will be some soon! The hardworking forecasters at NOAAs Climate Prediction Center produce timely and accurate seasonal outlooks and short-term forecasts year-round, said Michael Farrar, Ph.D., director of the National Centers for Environmental Prediction. Transcript (PDF): October 20 virtual media briefing on Winter Outlook 2022, National Centers for Environmental Prediction, National Integrated Drought Information System. December is favored to be the chilliest month on the Eastern Seaboard, with lower-than-normal temperatures expected from the Great Lakes down into parts of the Mid-Atlantic and Northeast.

As its normally colder higher up in the atmosphere, when the air rises up a hill, it becomes colder, and condenses to form cloud and precipitation. If we were to zoom into the tropical region, where sea surface temperatures have the greatest global climate impact, we would see some sea surface temperature differences of up to 0.2 C in the tropical Pacific and Indian Oceans. Typically, the first influence of these ocean anomalies can be seen in the jet stream patterns changing. As we discussed in this post, La Nina typically causes a reduction rather than increase in western U.S. atmospheric river activity. In the SPEAR simulations, I examined the relationship between the ensemble mean Southwest U.S. precipitation anomalies and the La Nina SST anomalies.

My conclusion: the chaotic weather variations are about 14 times more important than the variations in La Nia amplitude or flavor for Southwest U.S. precipitation, which is consistent with the figure above. But if these big picture findings hold up to further scrutiny, then it means that the typical or averaged La Nia precipitation pattern still may be the most reliable guide for seasonal predictions of Southwest precipitation in early winter, but we may have to rely on subseasonal and weather forecasts rather than seasonal outlooks to anticipate the sort of soaking that occurred in December and January of this winter. How harsh will winter be? I am no scientist. Less snowfall is forecast in the eastern half of the United States for the month of January. Next, I tackled the noise part of the calculation, which represents the Southwest precipitation variations that are unrelated to the sea surface temperature patterns. Below-average temperatures are forecast in the northern contiguous United States, stretching from northern Michigan to northern Washington state.
