Weather Story
Created by the NWS Grand Junction WFO
A shift in the weather pattern will bring cooler more seasonable temperatures to the area this week. This pattern will also be favorable for pulling moisture into the central Rockies and leading to a daily shower and thunderstorm threat, with storms lingering into the early morning hours. Though welcome some storms could lead to excess runoff, especially over recent burn scars.
