I think @andyhb might be a little gun shy after starting this thread for 2020 on the first of the year, lol. Early indications are the typical La Nina duality of things looking rather ominous for Dixie Alley and perhaps the Ohio Valley and Lower Mississippi Valley, but less clear for the better chase country further west/north especially in the traditional chase "season" of May and the first half of June.
Some thought 2007-'08 might be a good analog for this winter, which had already featured two fairly large outbreaks by this point in February which obviously hasn't happened, but all it takes it one as we saw in Alabama a couple weeks ago.
Andy's posted some good analysis here and on other forums about why 2021 might favor the more active analogs (1999, 2008, 2011*) more so than the "dud" ones (2006, 2012, 2018, etc) but all we can do at this point is wait and watch. Won't be anything anytime soon with all the cold air dominating everywhere east of the Rockies, lol.
*The usual caveat that the one day in particular we all remember that year for was so extreme it is HIGHLY unlikely to recur anytime soon, but never say never when it comes to the weather.
