The National Oceanic and Atmospheric Administration recently released their outlook for the upcoming winter season. Several things impact our winter weather patterns. Over the next few months, La Niña may have the biggest impact. La Niña is a cooling of the waters in the equatorial Pacific. These cooler than average sea surface temperatures can cause a ridge of high pressure to develop further north, ultimately influencing how the jet stream sets up over the U.S. La Niña often brings more storms to the Midwest, making for more wintertime precipitation. Meteorologist Rob Lydick takes a closer look at the full outlook in the video above.
