* WHAT...For the Freezing Fog Advisory, visibility one quarter mile or less in freezing fog. For the Air Stagnation Advisory, poor air quality will continue. This is due to an inversion and stagnant air conditions near the surface that will continue to trap pollutants. * WHERE...Valleys in eastern Curry County and Josephine County and Jackson County. This includes, the Illinois, Rogue and Applegate valleys, including Grants Pass, Selma, Cave Junction, Applegate, Rogue River, Medford, Eagle Point, Jacksonville, Ashland and surrounding areas. * WHEN...For the Freezing Fog Advisory, until 10 AM PST this morning. For the Air Stagnation Advisory, until 10 AM PST Thursday. * IMPACTS...Low visibility could make driving conditions hazardous. Freezing fog may allow spots of ice to develop on roadways. Poor air quality may cause issues for people with respiratory problems. * ADDITIONAL DETAILS...Strong valley inversions, very shallow mixing layers of less than 1000 feet, and calm winds are expected throughout the advisory time, especially during the overnight and morning hours. A weak front on Thursday may allow for a brief period of improved mixing and particulate dispersion.
