Strengthening high pressure along with the increasing daylight hours of May will facilitate elevated Ozone values for the next several days. In fact, peak 8 hour average Ozone readings are anticipated to be just within the Unhealthy for Sensitive Groups range today through Sunday. And thus, a High Pollution Advisory is in effect. Anticipate only very subtle improvement early in the next workweek.
Daily average PM10 is expected to reach the low Moderate range today followed by improvement to the Good range over the weekend. Values trend upward during the early part of the next workweek with low Moderate conditions anticipated by Tuesday (close on Monday). Daily average PM2.5 will follow a similar pattern with highest values expected today and lowest on Sunday before trending upward again.
