I don't think you could have beat last weekend for low humidity and warm temps as well as a breeze. I was at a HS graduation this past Saturday for one of my nieces that was held at Millersville U in Lancaster County and it was a gorgeous day for it.
But that weather is all history now.
Started off today with a low of 65 and reasonable dews in the low 60s but even that is also history. I expect 88 will be my eventual high for today.
It's currently the triple Hs - a hazy, hot, and humid 87, with lots of cumulus and a dp of 72.
