Denver in 2018 (Oct.), Chicago in 2009 (Dec.), Foxboro in2001 (Nov.). Hottest or so it seemed was LA in 2017 opening day. It was snowing in Denver, snow on the ground in Foxboro, and the wind was ripping off the lake in Chicago, but sunny. Funny thing about weather, when you w are winning the temps don't seem so bad, when you are losing the temps are miserable. So Denver was the coldest, but the most miserable cold was Chicago.
