At least locally, it might be March 2014. There was a tornado on the 27th that touched down in VT, crossed NH, and touched down again in ME. And I think about a week prior there was a pretty decent sized snowstorm for Maine. They had a snowy month in general. Two weeks prior all of NNE got a big storm on the 12th and 13th.
Otherwise I'd probably go with somewhere on the front range or something.
