Today was day #16 here to reach the 90 degree mark, and it's the 4th hottest day of the year. Assuming that the next 4 days reach the 90s, that would make an even 20 for the year. My highest temp for the year currently is 97 and any of the next 4 days could reach or exceed that.
It still hasn't been a bad summer for heat but I imagine we're going to build up a huge positive departure for September this week.
