Rain during the summer is very rare in the DL area. But it is hot. It's also been more humid than normal (for us) the last few weeks. Normal humidity would be under 20%, but it's been over that lately. The heat has been on for sure (a lot hotter already this summer than it was this time last summer). I'm guessing it's been low-mid 90s as a high in the last week (it's been over 100 in my area and DL is usually 10 degrees cooler). Normally, July is a bit cooler than August, with the first part of the month cooler than the latter part. August is our hottest month, July second hottest and September is actually third usually. Oth the 4th at DL I didn't even need to put my light jacket on in the evening and usually I do. On the 1st, though I did need it.
