Forecast Discussion: Temperatures and humidity will continue to rise on Memorial Day. It will be mostly sunny with breezy afternoon winds. Ozone and particles are on the rise across the region the weekend and this trend will continue on Monday. Ozone will reach the top of the Moderate range; a clean transport pattern and afternoon atmospheric ventilation should keep ozone below the Code Orange range. Particles will respond to higher humidity by increasing into the low Moderate range. **Extended Forecast: Hot and humid weather will continue on Tuesday and Wednesday. Increased chances for afternoon clouds and a clean transport pattern will allow ozone and particles to persist in the Moderate range. -Huff
