Wider weather episode

Monsoonal moisture pushed northward across western Colorado as the ridge of high pressure tilted eastward. As a result, precipitable water values exceeded an inch over the southern and central zones. Given the increase in midlevel moisture, scattered to numerous showers and thunderstorms developed over the region. Some storms produced heavy rain which led to localized debris flows including across portions of the Grizzly Creek Fire burn scar.
