Forecast Discussion:
An upper level low pressure system off the southern California coast this weekend will help usher in atmospheric moisture and bring chances for showers and perhaps a thunderstorm or two. Have increased Saturday's and Sunday's PM10 forecasted values a bit and added a mention of blowing dust as there is a slight chance for some pop-up thunderstorms and associated localized outflows. Even though the forecasted PM10 levels are elevated a bit over the weekend, they are still in the good AQI category (i.e. low dust risk). The chances for showers remain for Monday, though in areas to the south and east. The longer range forecast has high pressure building into the area for the second half of next week.- S.DiBiase
