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

The back of my envelope tells me that to exceed the GISS 2016 temperature record (1.02C) the average temperature anomaly for October,November and December must exceed 0.93C.
Since the average for the last four months was 0.90C, a new record is looking less likely
