The MJO "stall" could be artifact of the models and it's a known bias of the models to be too slow moving convection across the Maritime Continent. The current MJO has been on the faster side of what is typically expected, so a stall would certainly break the tendency over the past few months.
Tropical forcing (MJO) place a role in modulating the PSV and one of the ways is by driving heat flux and the models are currently seeing that.
Now beyond that, there is no guarantee of a SSW and the results are uncertain. Maybe some other posters that know more about SSW will chime in.
Winter time post are almost exclusively focused on the DFW area.
