Look at these wind gusts in the Front Range... up to 80 mph in the Foothills.
Bone dry relative humidities down to 8-10% will make for extreme fire danger.
If anything crops up in the mountains west of Boulder, it will be fanned east quickly. Please take this seriously.

I really hope that no fires occur. If one were too, we likely could get another Marshall fire type situation
