Why were you talking about April yesterday then?
The interesting thing about May is that yes, since 2015ish there have been a similar number of top tier warm ones to the summer months. The difference is that most of those were 2015-2019, and a good number of the other recent Mays have been quite seasonable (unlike July and August).
In addition, it's not a linear warming signal into the summer...at OLM, for example, there have been 4 top tier warm Mays since 2015, but only 2 Junes. But the clearest fact is that no other months can compete with the consistent increase in temperatures that July/August, the peak of summer, has seen.
Yeah, precip is still a wild card and there are some convective type scenarios where the month could still hit average there.
But temps are clearly going to be warmer than average, just a minor question of scale at this point.
