The NY Times has an Accuweather database that shows the daily high and low temperatures for 2019 (and monthly accumulative rain) for many small and large cities. The article was more about comparing 2019 average temps to long term temps. Still interesting to see. I know you can find such graphs elsewhere, but this is an easy site to use. (Wasn't sure which, if any, forum this thread is most appropriate. It's good for thinking of heating needs.)
