Forecast Discussion: Warm and sunny on Sunday with increasing humidity as winds back to the southwest. Air quality will be in the Moderate range with ozone as the leading pollutant. Particle concentrations will reach the Moderate range along the I-95 Corridor For Monday, mostly sunny, hot and humid although increasing winds will allow for good ventilation and keep air quality within the Moderate range. A weak cold front is expected early Tuesday with improving air quality in its wake although locations along the I-95 Corridor will see peak ozone concentrations reaching the low Moderate range. - MDE/PSAQFO
