It seems that we're getting an increased number of cool season setups and it also seems like we're getting lower-end setups to actually produce. This gets into the EF-0 stuff but given the warmer waters we're seeing increased llvl CAPE values with higher shears in place. I think dual-pol has also helped sizably in identifying quick spinups but as "garbage" as those seem they are still important to identify.
But I really do miss the 90's. I know sometimes our perception is far different than reality but it seemed we used to get several solid squall lines every summer. I always used to get pissed though b/c these things would get to Hartford, completely fall apart, and then sometimes rebuild east. But those years not only had solid squall lines...but we would also get some decent nocturnal events too (especially August). August 9, 2000 was wild.
