Forecast Discussion: Monday will be an Air Quality Action Day! Particle concentrations are at the upper end of the moderate range this afternoon (Sunday) and light winds overnight will allow these high concentrations to linger into Monday morning. There will be very limited vertical mixing and an increase in humidity on Monday with light rain likely late in the day. These weather effects, coupled with high weekday precursor emissions, will allow particle concentrations to increase to the Code Orange (Unhealthy for Sensitive Groups). Extended Forecast: A pulse of strong onshore winds early Tuesday, along with continued rain, will drop particles into the upper Moderate range Tuesday. Strong southerly winds Wednesday will drop concentrations a bit further on Wednesday. -Ryan
