Page Counties…UNHEALTHY TO HAZARDOUS AIR QUALITY WILL LINGER UNTIL 9 AM ON SUNDAY…

Unhealthy to hazardous air quality has developed over much of eastern Nebraska and southwest Iowa early this morning, and these conditions will likely linger until around 9 AM. The poor air quality is the result of lingering smoke from Saturday evening fireworks activity which has become trapped near the ground by a
temperature inversion and stagnant air flow pattern. Conditions are expected to improve after 9 AM as increased atmospheric mixing allows for the dispersion of the smoke.

Those with respiratory concerns should avoid outdoor exposure until conditions improve later this morning.
