Colorado weather forecast warns of heavy rain and flash flooding

A significant storm system is expected to bring heavy rain and potential flash flooding across Colorado this week. The weather pattern is transitioning from mild conditions to stormy skies, with moisture being pulled into the region from a Pacific storm system and the remnants of Hurricane Polo.

In southern Colorado, a Flash Flood Watch is anticipated as multiple rounds of heavy rain move through, particularly in areas along and south of Highway 50 and the Eastern Plains. The most active weather is forecast for Tuesday through Thursday, with Wednesday expected to be the wettest day.

In the central and northern mountains, the weather will bring increased cloud cover, rain, and the beginning of the season's snowpack. While much of the precipitation is focused on the southern half of the state, mountain towns like Aspen may see up to an inch of rain. Temperatures are expected to drop, with highs ranging from the mid-50s to the 60s in many areas, though the Eastern Plains may remain warmer.
