Saturday brings us another round of clear air, one that looks as if it might stay around for a couple of days. PM2.5 levels should begin to drop early in the morning, but this clearing may be more gradual than others we've seen recently. We could be in the Good/Moderate range as early as 6AM or as late as 2PM, but we think it's most likely to arrive closer to 10AM. Once the air clears, it looks like we'll have a beautiful day. And SPOILER ALERT - Sunday is looking nice as well.
UPDATE – Our prediction with overlay of actual readings:
