Warmer than average weather is the main message in the autumn outlook issued by the Climate Prediction Center. Most of the nation is expected to see above normal temperatures, covering the period from September to November. Only the Southeast is expected to see near average temperatures, where wetter than normal weather is anticipated. The Southwest may also see above normal precipitation. The Northwest is the only area with a drier than average prediction.

The drought forecast, covering the same time range through the end of Novembe, looks for improvement in the Southwest. Drought development or persistence is expected in the Northwest, Upper Midwest, and over most of Texas.

The Climate Prediction Center states “the temperature and precipitation outlooks are consistent with the elevated probability of El Nino development and its impacts, with adjustments related to model forecasts and decadal timescale climate trends.” El Nino has yet to develop in the Pacific Ocean, but an El Nino Watch has been issued. The strength of the upcoming El Nino is still uncertain.

El Nino (translated from Spanish as “little boy”) is a natural ocean-atmospheric phenomenon producing warmer-than-average sea surface temperatures in the central Pacific Ocean near the equator. It is usually marked by a warmer than average winter in the northern tier of the nation, with most of the southern sections of the country seeing above average precipitation.
