The winter is not even close to being over if this becomes fact. It might make the early January outbreak look like chicken feed.
Is there a link to that or is it for paid subscribers only? I wouldn't exactly call what has turned out to be one of the two worst Arctic outbreaks since 1990 "chicken feed", but yeah it technically can get colder here by 5-10 degrees in the more extreme events.
Note though that since the close of January looks mild an extreme event would have to be pushed back into February, which makes it that much harder for a really bad outbreak to occur after a warm spell will have melted away much of the snow to our north. The early January event also came at the end of a long general pattern of below normal temperatures, and trying to get back into another nasty rut like that after weeks of improving winter conditions will make it even more difficult. Sure it'll get cold again, but unless some massive pool of cold weather starts building in Alaska a la January 1989 or 1951 I don't see an historic outbreak in the cards (and neither of those winters were El Niño years). Both of those winters, along with the textbook case of 1933, had very mild Januarys with no major cold discharges like what we just had. What grimly looked like was turning into a nasty late-70s type winter just a couple of weeks ago appears well on its way to self-correcting
We just emerged from some of the coldest weather in a generation, you have to go back to 1996 to find a comparable outbreak, expecting anything colder is probably unrealistic and something nobody is hoping for. Now next year may be another matter, severe winters often tend to come in clusters
