If this is the solar minimum where is the cooler weather? I’m not a globull warming acolyte but I do wonder what happened to the colder and wetter fall and winter weather of my younger years some 40 years or more ago? We used to have consistent wet and cool falls. What Dad called tree planting weather. Days on end of overcast skies with steady drizzle and temperatures never over the 50s in the daytime.
Last fall and this one it has been blue bird days, warm and NO rain. We had almost no rain at all for the entire winter last year and only one brief period of cold weather in December and January.
When I was a kid we sledded often in winter. We bundled up for foot ball games in late September. Not now and not for many years.
What area of the country are you living in. I have noticed similar trends over 60 years in the mid-Atlantic area, especially regarding temperature.
