2018 was wild...especially the tornado events we got in September. Severe climo across the country in general though has been a bit off the past several years...hell, this past May I think was historically low in terms of tornadoes.
I still remember that day like it was yesterday. The period between 05/29/1998 - 06/02/1998 I bet would be the most active 5-day period of severe in the Northeast on record.
