Weak El Nino conditions favor relatively mild winter temperatures across Minnesota, the Upper Midwest and much of the rest of the country, the National Oceanic and Atmospheric Administration said Thursday in its annual winter outlook.
The tropical Pacific has gradually warmed recently, leading to the expectation that an El Nino will develop and affect weather during December, January and February, the federal agency said.

Around 75 percent of the United States is more likely to be warmer than average, and no part of the U.S. is favored to see below-average temperatures for the winter, NOAA added.
Federal weather forecasters also see above-normal temperatures coming in November for nearly the entire country.
