A Pacific weather system will move through the southwest states tonight through Saturday. This will bring a chance of light rain to the forecast area Friday along with cooler temperatures and some minor breeziness at times. An unsettled weather pattern continues next week with the next opportunity for light rain in the Monday-Tuesday time frame.
Daily average PM10 levels are expected to see an improving trend due to improved ventilation at times and some modest precipitation (nudging back to the Moderate category Monday). Daily average PM2.5 however will not see the same kind of improvement due largely to residential fireplace activity having an offsetting effect and thus it is expected to remain in the Moderate range. Average Ozone is expected to remain in the Good range thanks in part to the time of year as well as above average cloudiness over the next several days.
