Once again, fog will form overnight and stick around Thursday morning. Give yourself a few extra minutes as I'm tracking a slow-going, soupy commute in Eastern Washington and the Columbia Basin. Fog stays through mid-day before making way for partly cloudy skies. Areas south could see a good deal of sunshine and blue sky. Daytime highs will climb to the upper 20s Thursday.
The Air Stagnation Advisory is in effect for most of Eastern Washington through Friday afternoon. It could stick around through the weekend as well. Low clouds and fog will trap pollutants in the lower levels of the atmosphere, so folks with respiratory problems beware!
We could see a few showers by the middle of next week -- still just a slight chance!
Slow your roll on the roads! -DG
