Is back. Welcome to our special 3 00 p. M. Edition of bay area news. The chiefs and texans kickoff at 35 30. Spare the air alert extends through tomorrow. Here is a look across the bay area. This is the view from all 20 of our live cameras. The eerie and orange color we saw yesterday, today a lot of smoky gray. The air quality is actually worse today. Most of the haze caused by several near by wildfires and just like yesterday we are seeing ash falling like snow in many parts of the bay area. Jeff is going to join us in a little bit.

We are still in the unhealthy range here for much of the bay area with that smoke and that haze staying pretty constant.
