September Weather Review

September of 2024 followed the last few months of summer, in which a meandering ridge of high pressure across the Rockies brought periods of very warm temperatures, as well as allowing for a few passing weather systems and fronts to bring brief cool downs and rain and higher mountain snow across the region. For the month of September as a whole, above normal temperatures and generally below normal precipitation was experienced across region, save for above normal precipitation for portions of south central Colorado into the southeast mountains and far southeast Plains.
