Both smoke and haze are visible today across Colorado from a wild fire burning in central/northeast Arizona. The Tinder Fire, which started on April 27th, has grown to an estimated 8000 acres. Strong southwesterly flow aloft in the atmosphere has swept the smoke up from Arizona into Colorado. The smoke has mixed down to the lower levels near the surface which is why we can see and smell the smoke.
A cold front tonight and northerly winds tomorrow will help to clear any smoke and haze from the skies through Tuesday.
