Forecast Discussion: The presence of weak winds in the Valley led to a strong increase in ozone yesterday. In addition, clear skies allowed for an increased production of this pollutant. Looking ahead, it seems stable conditions are here to stay. The high pressure system overhead will establish a southwesterly flow with weak surface winds. Therefore, atmospheric movement will be fairly low and keep ozone in the Moderates. Without gusty winds in the afternoon to clear out the air shed, pollutants will likely pool in the Valley. Focusing on PM-10, it seems the risk of dust activity will be low for the next few days. We had a dust storm move through the Valley on Friday followed by strong rain showers. As a result, soils have stabilized once again. With several days of afternoon heating, moisture should evaporate and dust activity can return to the region given the right wind speeds. In the meantime, expect quiet conditions in the Valley with ozone being active for this week. Check back tomorrow for more. Until then, have a good day! -P.Patel
