88° was also the high at my house, but we had a lot of cloud debris all day. Never really had sun for more than 20 minutes at a time. Didn’t get a drop of rain which I’m happy about.
I’m cautious and a bit paranoid, so I wouldn’t necessarily use them in a closed wall, but “shark bite” fittings make home plumbing so much more of an enjoyable task.
Weekend looks warm but Sunday is the interesting day. Is it mid 80's or mid 90's in the hot spots? Sunday has gotten progressively warmer with modeling. Looks like precipitation chances are minimal, so maybe this is the weekend that breaks the streak!
