I think we will get cold periods during future winters, what ive learned with low minima sun, is weather patterns can get stuck in a rut due to amplification of the jetstream, instead of our normal westbto east jet flow, the jetstream meanders around like its no particular place to go. I do believe there is a lag effect too, so i would expect winter 2019/2020 to be particularly severe. As for spring and summer...roll the dice, either droughts, or floods or maybe both.
