Check out the replies to the tweet. One notes that Alaska is usually cool. Also note that, surprising, La Nina stops at the US-Canadian border. If you find any patterns, let us know.
So far, this autumn has been a moderate La Nina. Generally that means depressed global mean surface temperatures, so 2020 may not quite surpass 2016 as the hottest year.
A moderate to strong La Niña is now likely for the upcoming winter. While this pattern is warm for most of the Lower 48, there is a lot of variability. This map set shows temps during the 14 strongest La Niña's since 1925. [Corrected a title mistake on a previous post.] pic.twitter.com/Pxk5mDXk8z
