Without really doing research, drought doesn’t seem to have a great effect on tornadoes.

1988-1990, for example, were drought years in much of the Midwest. There was not not a particularly low number of tornadoes.

Low tornado numbers in 2000 and 2001. Closest noticeable droughts were 1999 and 2002.

Winter 2011 into 2012 was really warm for us, then spring in 2012 was really warm, and then summer laster year was brutally hot and we had a massive drought.
This Winter 2012 into 2013 was mediocre, then spring has been brutally cold and just a lot of rain so far.
I'm don't know much more than a layman when it comes to weather, so I'm not sure how winters & springs almost complete opposites of each other equals the same result (brutally hot summer with drought).
I'm betting on a mediocre summer that isn't anywhere near as hot as last years was, and a normal amount of rain throughout the summer months.
