ST. LOUIS, MO (KTVI)- Notice that haze? Well, that's smoke and it's getting thicker over the central United States.  The smoke is coming from wildfires in Alaska  and the Canadian provinces of Alberta and Saskatchewan and being carried southward on upper level winds.

Many noticed the red appearance of the moon overnight and the sun Tuesday morning. The particles of smoke in the air scatter the light, allowing the longer red wavelengths to be seen more than the typical, shorter blue.
