Northwest areas of the state continue to dry out, where conditions range from extreme to exceptional drought, amid the high fire danger.
Critical fire weather conditions are likely to push into Wednesday with winds gusting up to 25 miles per hour and low humidities lingering over high mountain valleys. Showers and thunderstorms will also be possible, mainly over the high country.
Warmer and drier weather will continue again on Friday, with chances of thunderstorms rolling back into the mountains on Saturday.
For September, the latest outlook from the Climate Prediction Center (CPC) calls for the likelihood of warmer than normal temperatures across northwest Colorado with below normal precipitation. This could impact the timing and intensity of fall colors.
