The first day of September marks the beginning of climatological fall, but it certainly won’t feel that way with a stretch of 90s coming up. Tuesday starts this streak, with highs expected in the low 90s after a low-to-mid-70s start. Ridging aloft will continue to build over the area, and that should suppress much in the way of shower and thunderstorm development in the afternoon, though a stray popup isn’t out of the question.
