There will end up being 6 days of 70+ at Detroit which is a November record, breaking the 2015 record of 4. Several sites in Southeast Michigan had 6 or 7 days of 70+ in November 1975 but DTW officially only had 3 (several 69s). Today's high of 77, by far the warmest of the stretch, is the warmest this late in the season, beating 75 on Nov 9, 1999. An impressive stretch of Indian summer but with sunny skies, rapidly cooling nighttime temps, and the time of year it is, its a stretch that won't stick in the memory bank like other warm or cold spells do.
