Of note we have not had a 90+ day in May since May 3, 2018. In that year we ended with 4 days above 90 that summer. The last time we had earlier 90+ temps (April/May) was on April 26 and 27, 2009. In that summer we never again saw a 90+ day as those 2 were the only times we were able to crack 90 that year and 1 day was 89.5. Before that our last 90 in May was on May 4, 2001.
