Forecast Discussion: A warming trend will begin on Saturday and will continue through Monday, bringing some respite from the recent mid-winter-like weather. It will still be colder than average on Saturday, but a shift to southwesterly flow will pump warm and humid air into the Philadelphia metropolitan area, bringing temperatures to about average on Sunday and to near 70 °F on Monday. The arrival of warm air aloft will inhibit atmospheric mixing and allow particle concentrations to rise to the mid-Moderate range over the weekend. Rain associated with the arrival of a warm front will overspread the area from south to north overnight Monday into Monday morning. This precipitation will reduce particle concentrations but they will remain in the Moderate range. **Extended Forecast: A cold front will arrive on Tuesday. Particles will linger in the low Moderate range until the new air mass is able to fully build in behind the frontal passage. -Huff
