Smoke from wildfires in Canada is moving into parts of the central US and could linger in the days ahead, health and weather officials warned Thursday. Air quality alerts have been posted as of early Friday across several states, including Nebraska, Washington, Montana and Wisconsin, with a special weather statement about air quality in Wyoming. The heaviest smoke concentrations should shift further east into the Midwest later in the day, affecting major metro areas including Chicago, Indianapolis and St. Louis. …In Nebraska, “Canadian wildfire smoke is going to move through the area today through tomorrow morning, resulting in potentially dangerous air quality and poor visibility across eastern Nebraska and Iowa. Limit outdoor activities if possible when the air quality is poor!” the National Weather Service in Omaha tweeted Thursday.
