The December temperature outlook favors well above average temperatures across most of the country, with the exception of much of California, the Southwest, and Maine, where equal chances (EC) of above-, near-, or below-normal temperatures are predicted. Since the MJO is expected to remain active and progress towards the Maritime Continent and then the west Pacific, forecasters also considered potential MJO impacts. But the Madden-Julian Oscillation (MJO)-a conjoined area of heavy rains and clear, calm skies that travel the tropics together as a couple-was active over the Indian Ocean at the end of November. El Niño continued to strengthen during November across the tropical Pacific and was again considered as a dominant teleconnection for the outlooks during December. Other tools that forecasters considered this month were various longer-range forecast models such as the Global Ensemble Forecast System (GEFS), the Climate Forecast System (CFSv2), and products derived from these models. The updated outlooks were produced considering the Week 1 forecast from the Weather Prediction Center (WPC), and CPC’s own Week 2 and Week 3-4 outlooks. More details about interpreting the outlooks can be found here. And before we dig into the specifics of the outlooks, just a gentle reminder that the colors on the temperature and precipitation outlook maps only provide information about the most likely outcome, but other outcomes are always possible, just less likely to occur. I’ll also discuss the current state of drought, how it changed during November, and the drought outlook for December.

White areas indicate that there are equal chances for a wet, dry, or near-average December. precipitation outlook for December 2023 (view Alaska), showing places where a much wetter than average December is favored (greens) and where a much drier than average December is favored (browns). The precipitation outlook favors well above average precipitation (rain and/or snow) in the Pacific Northwest, in parts of the central and southern Plains, in the Southeast, and along much of the Eastern Seaboard, with well below average precipitation only favored in parts of the northern Plains. The temperature outlook favors well above normal temperatures across much of the nation, with the exception of the Southwest. On November 30, CPC released its updated monthly climate outlooks for temperature, precipitation, and drought across the United States for December 2023.
