Forecast Discussion: Winds will drop to near calm on Saturday morning and stagnant conditions will continue through the remainder of the weekend and into Monday morning. Particle concentrations will begin to rise on Saturday but a clean start to the day will keep the daily average just within the good range. Extended Forecast: A further rise in particle concentrations due to stagnant winds will push air quality into the moderate range on Sunday. The day of most interest will be Monday as three days of light winds will allow particle concentrations to accumulate well into the moderate range. There is a chance of Code Orange air quality on Monday. This forecast will be updated over the weekend as necessary. -Ryan
