Fireworks and distant wildfires are showing up in the air above Omaha.
The Douglas County Health Department is forecasting moderately elevated levels of particulate pollution today and Tuesday, due to smoke from fireworks.
For most people, the air quality is acceptable, according to the county. Individuals suffering from heart or lung diseases, or who are older or very young may want to limit outdoor activity, according to the county.
Typically, air quality drops during the July 4th holiday and in certain weather patterns can drop significantly on the night of July 4th.
Hazy skies across the region Sunday were due related to wildfire smoke drifting southward from northwest Canada and Alaska, according to the National Weather Service.
In satellite images of North America, the smoke appeared as a faint cloud above Nebraska, Iowa, Kansas and South Dakota on Sunday.
The same weather pattern bringing cooler than normal weather to the region has ushered in the smoke, said Rick Chermok, meteorologist for the National Weather Service.
A large dip in the jet stream is allowing Canadian air to flow southward into the central U.S. The smoke is dispersing today, Chermok said, but another batch along Minnesota-Canada border could flow southward into our region, he said. Smoke from the fires is too high in the sky to be related to local issues with air quality, he said.
