You bring up an interesting/extra point in saying extreme, all time...at least the way I read your post. Summer heat has been extreme for much of the country and locals in each area have certainly taken notice but I feel like as a whole we are in this mode of hyper drama where daily extremes are almost expected now. Not just in weather but in all phases of life. It has been something coming on for years but the daily covid updates and people sitting at home seemed to to really stoke it. I believe that 20 years ago the Palouse and Mid Central heat waves would be constant headline news now you have to search to find them on a typical news web site. Another example would be the US Basketball team. That loss to Nigeria was SUPER historic on several levels. One of the biggest upsets in sports history. Yet its just a news item that comes and goes with the daily drama.
