Forecast Discussion:
Thick clouds have enveloped the Valley this morning and you may be wondering, "when is it going to rain?" Well, some lucky areas have already seen light rain, but those areas are in the minority. As the day progresses, rain chances will gradually increase for the Valley; rain should be mainly light. Then by early Wednesday morning, a cold front will cause heavier rain. Rainfall totals through Wednesday morning could end up between 0.15" and 0.50".Air quality-wise, this morning is great. Southerly winds, and possibly rain, are helping to keep local PM10 (dust) and PM2.5 (smoke) levels low. Breezes later this morning may result in pockets of dust from dust-prone areas, but for the most part, PM10 and PM2.5 are expected to remain low. Ozone will also be a non-issue as clouds prevent its formation (ozone needs sunlight to form).
Tomorrow morning should be edition #2 of great-air-quality mornings. This time, winds will be stronger and rain heavier, an effective combination to stamp out local PM10 and PM2.5. Later in the afternoon, winds will weaken substantially, rain chances will depart, and skies will start to thin out. Ozone should remain in the Good Air Quality Index (AQI) category however, given the low pressure pattern overhead.
For Thursday into the weekend, PM10 and PM2.5 should trend upwards again. However, PM2.5 will have a greater potential at rebounding, especially given the cooler mornings. Both pollutants are forecast in the Good AQI category each day, though.
Lastly, ozone may be able to squeeze its way into the Moderate category on Friday. But an active weather pattern and periodic clouds will help to limit it on other days.
Tune in tomorrow for the next air quality forecast!
