A heat wave currently roasting the southeastern US is expected to spread into the country’s Midwest and northeast, potentially affecting nearly 250 million people, with temperatures up to 40C.
I remember as a kid during the summer in my area we would have maybe like a few days or a week of heat and that would be the heat wave for the year. Then it became 1-2 weeks of heat, then multiple heatwaves per year, and now it's just common for the heat to hang around all summer and then a solid 2ish months of high temps from like October to mid/late November. Last year I was wearing my summer clothes through early December. very cool and not concerning at all
