Yes, we've had hotter summers since with many more 90 degree days. The Dust Bowl era had some amazing and historic heat though, there are records from 1936 that still stand to this day, not just city records but state records from across the country. And 1931-32 is still considered one of our warmest winters on record.
My top heat summers in chronological order are 1944, 1955, 1966, 1977, 1980, 1983, 1991, 1993, 1995, 1999, 2002, 2010 (note how many of them are in the 90s lol.)
