Did it seem cooler this past month? Many locations will end September with below average temperatures. In fact, it's been about 7 years since our last below average September, temperature wise. The last time NW Oregon observed below normal temperatures in Sep was back in 2019! pic.twitter.com/oz35XrVqFG
