NWS Forecast Office Flagstaff, AZ

It will be a warm weekend, especially on Sunday when mountain highs will be in the 80s and lower valleys will reach to around 105. There is a slight chance of a few thunderstorms on Saturday over Coconino County as well as the White Mountains. The morning hours are best on Saturday for that long hike or other outdoor activity, as there will be a lightning risk during the afternoon. Sunday should be great for outdoor activities, other than the heat at lower elevations. Take precautions in you plan to be outdoors in those areas.
