Thursday's air quality will almost certainly be a disappointment compared to Wednesday's. We are expecting increasing PM2.5 levels overnight, bringing us to Unhealthy or Very Unhealthy conditions. We will likely see a reduction in the pollution between about sunrise and noon, and we could see our lowest pollution levels of the day at that point. Then we should see increasing pollution for the remainder of the day, likely moving us up to Very Unhealthy conditions.
EXTENDED FORECAST
FRIDAY, January 3: There is a good chance of clearing skies in the morning leaving us with Good/Moderate air quality before lunch, then likely deteriorating air quality in the evening.
SATURDAY, January 4: From this far out, Saturday’s air quality is difficult to predict. But from here, it looks most likely that we will see air quality at Unhealthy or worse, possibly with significant increases in pollution in the evening.
SUNDAY, January 5: Look for somewhat improved air quality in the morning as compared to Saturday, then deteriorating conditions in the afternoon and evening.
