I think the larger part of the poster’s hypothesis is based on the fact that this year, vs last year, the cold has lingered much later into the season. That is surely true in this area (NOVA), where we rarely see 40 degree temps in mid-May, yet last week our temps ranged from 41 (overnight) to one day hitting 82, which is a more typical daytime temp here by mid to late May.
It sure doesn’t feel like Summer. It doesn’t even feel like Spring some days. This year our mid-day high temps have ranged primarily in the 60s. Throw in a couple extra hours of daylight, and the hypothesis isn’t so far out.

Do not confuse weather with climate.
There are very complex reasons why a “hurricane/tornado season” emerges (none based on AGW), but extended daylight is not one of them (any more than in any other year).
