This Week in Colorado Weather: September 15, 2025

September 15, 2025 / Ben Castellani

After a sunny and warm start to the week, the Front Range will trade blue skies for gray as a sluggish low-pressure system settles into northeast Colorado for several days. Rain chances build Tuesday and linger through Thursday, with well below normal temps and a few rounds of storms in the mix. But don’t expect a soaking: rainfall totals may vary widely, with the heaviest action likely landing northeast of Boulder and Denver towards Nebraska. The storm exits sometime Thursday leaving behind drier and warmer weather for the weekend.

The days ahead are shaping up to be much more pleasant with warmer temps, limited storm chances, and a break from the smoke (at least for now) under southwest flow. Read on for a full breakdown of this week’s weather, including when to expect the best shot at rain and whether any smoke may return in the extended.
