Daily changes in weather from day to day in 2022 were more varied from the Southwest United States to the Midwest and Northeast than they were in 2020, while variety decreased from Texas into the Southeast, as well as southern and southeast Alaska. Interestingly, these changes were generally seen across high temperatures, low temperatures, and precipitation. So daily variety increased between those two years where it already is typically higher, and decreased where it already is typically lower. This could indicate that 2022 was more of a “typical” year variety-wise than 2020 was.
These were determined by calculating the accuracy of persistence “forecasts”; that is, assuming the weather would stay the same from one day to the next. The less accurate those were, the more the weather varied from one day to the next.
