Hot this weekend, a little cooler early next week, then hot again as we go into the 4th of July weekend. Only real chance of rain in late Sunday into early Monday.
It's been an odd season - I think the thing that stands out from perhaps "normal" years is the amount of days that have been downright pleasant. Perhaps that leaves some people feeling like it's been cooler than normal overall, that just isn't the case. If I didn't know better I'd have guessed that we were running a little below normal for met summer...and I've had 8 days of temps at or above 90.
Edit: Not all of those 90 degree days have been during met summer.
