It spurs the potential for more winter storm systems, but also elevates the chances of cold arctic air breaking off and moving further south called the polar vortex.<img src="https://img.particlenews.com/image.php?type=thumbnail_580x000&amp;url=3nkqJx_0wBWCJXn00" alt="https://img.particlenews.com/image.php?url=3nkqJx_0wBWCJXn00" width="648" height="365" ><img src="https://img.particlenews.com/image.php?type=thumbnail_580x000&amp;url=1ktuiq_0wBWCJXn00" alt="https://img.particlenews.com/image.php?url=1ktuiq_0wBWCJXn00" width="648" height="365" >We're looking at a weaker La Niña signal this winter, and because of that, the likelihood for these cold air outbreaks will be influenced by other factors that may help to keep the polar vortex from meandering too far south.The seasonal outlooks show higher chances of above-normal temperatures along the southern U.S. and colder conditions for much of the northern Great Plains.A higher chance of seeing above-normal precipitation for our area and our neighbors in the Great Lakes region.<img src="https://img.particlenews.com/image.php?type=thumbnail_580x000&amp;url=1YUf6N_0wBWCJXn00" alt="https://img.particlenews.com/image.php?url=1YUf6N_0wBWCJXn00" width="648" height="365" >You can check out NOAA's full outlook here.</div></body>
