Not sure if this applies to this year, but if Bolshaya Udina erupts, it might mean a pretty inactive couple of years for severe weather coming up. Large volcanic eruptions spew a lot of sulfur dioxide and sulfuric acid into the atmosphere, which has a sort of "reverse greenhouse effect", increasing the albedo of the atmosphere and causing less energy from sunlight to reach ground level. This could throw a major monkey wrench into any severe weather setups.
Then again, 1981 and 1992 were both fairly active years for severe weather, and were right after the eruptions of Mt. St. Helens and Mt. Pinatubo, so an eruption isn't necessarily a guarantee of a dead season or seasons afterwards.
Ensembles picking up on a possibly very active late June mostly across the northern plains and maybe Ohio Valley; we are well above 75th percentile for tornadoes this year so this could keep us above average for a while to come.
