The Climate Prediction Center has issued a La Niña Watch for winter 2021-22. There is a potential for La Niña to emerge this fall and last through the winter, with a 66% chance of La Niña conditions during the November - January time period.

La Niña is a seasonal cooling of water temperatures in the central Pacific, coupled with changes in atmospheric winds, which can affect weather patterns far removed from the tropics. In the lower and middle Ohio Valley La Niña tends to increase our chances of wetter and warmer than normal weather. However, it is very important to remember that La Niña is just one player on the vast team of factors that combine to produce our weather. La Niña/El Niño is one of the better understood signals and can have a significant effect on weather patterns, though, so it's definitely worth watching.
