Storm Update – Mon 05/18/26 8:00AM | Rain and higher elevation snow ramp up through the day, freezing temperatures unlikely tonight

A fresh surge of moisture, lift and colder air are flowing into the Front Range today, with rain, high‑elevation snow, and even a few rumbles of thunder unfolding before the storm finally winds down Monday evening. The highest terrain could quietly overachieve on snow, while the Boulder-Denver area stays mostly just rainy. We also check in on the declining chance for sub-freezing temperatures Monday night.
