Have fun getting snow if this happens. Looks like a familiar path too.
Indeed, the last 10 years have had a significant increase in the average # of days/winter in Maritime Continent phases 4 and 5 vs what the 1980s had. Just looking at warm phase 5, during 1981-1990 the highest # of days for any one year in DJF was only 11. But during 2009-2018, the highest was 21 and 7 of the 10 years had 14+ days! So, it really looks like there is something to this research that may help explain a major reason for the SE US' warmer winters recently.
I discovered this just last month after reading what this link said:
