I feel winters in our region took a different path after the Super Nino in 2015-16. Think about it.
2014-14 was the last widespread cold and snowy winter. Since then we've barely managed to get a decent winter. 2015-16 and 2016-17 were warm. 17-18 had that mid-late Dec - early Jan and 2 week Feb period of winter. 2018-19 lasted 6 weeks (mid-Jan to late Feb) and then the last two including this winter have been crap.
Prior to 2015-16 we had longer lasting winters with more phased storm potentials. For example, 2013-14, 2012-13, 2010-11, 2009-10, 2007-08 etc. Just a personal opinion.
