I fear the same thing, too. Sensible weather wise, this late spring/early summer reminds me of 2002. (This is all from memory, so I could be way off--too lazy to look at the almanac.)
I think we had an early heatwave in May 2002 around Mother's Day. June and early July were pleasant with some heat spikes like this year, but nothing sustained. Around July 4th, we had a big cold front push through keeping our temp and humidity in check until about July 10th or so. Then we were off to the races.
The remainder of July, August and the first half of September were scorching and dry. I think we had some tropical remnants come through mid/late September that finally flipped the pattern.
The big difference between now and summer 2002 was we were heading into an El Nino that year. Just curious to see if this summer follows a similar course (cause we know how winter 2002-03 turned out.) .
