This Week in Colorado Weather: August 28, 2023

August 28, 2023 /

A very typical, though somewhat boring late-summer week will unfold across the Front Range as the monsoon wraps up and we await the seasonal arrival of the polar jet stream. Our best chance of rain this week comes immediately on Monday as afternoon thunderstorms rock the area. Drier and hot weather will return in the days to follow, however.

Hot and dry conditions will take over today and continue the rest of the week as a mid-level ridge develops over the central Rockies forming a long ridge axis from Texas, through Colorado and across the Pacific Northwest --- as shown below.
