What: Decreased air quality is likely to develop Friday morning. This is due to an inversion and stagnant air conditions near the surface that will trap pollutants within the valleys of Klamath and Lake counties.
Where: Valleys in Klamath and Lake counties.
When: From 10 AM Friday to 10 AM PST Sunday.
Impacts: Poor air quality may cause issues for people with respiratory problems.
Additional Details: A strong area of high pressure will build in through Saturday, then weaken slightly on Sunday. This will lead to poor mixing of the atmosphere and the trapping of pollutants. The high is likely to strengthen again early next week.

Persons with respiratory illness should follow their physicians advice for dealing with high levels of air pollution during periods of stagnant air.
