Strengthening high pressure along with the increasing daylight hours of May will facilitate elevated Ozone values for the next several days with readings expected to be in the upper Moderate range. In fact, peak 8 hour average Ozone readings on some days (most likley today and Monday) will be pretty close to the threshold for Unhealthy for Sensitive Groups.
Daily average PM10 is expected to reach the low Moderate range most days of the forecast period except for Sunday (Good range) due to reduced commercial activity.
Daily average PM2.5 is expected to remain in the Good range through the forecast period with the best day being Sunday (reduced commercial and transportation activity) and then trending upward during the early part of the next workweek (approaching the Moderate threshold on Tuesday) as commercial and transportation activity trends upward.
