PM2.5 - 4 Good
Enjoy your outdoor activities.
Current Conditions: At 3 p.m. EST this Friday afternoon, a cold light rain is falling across the area with a brisk westerly wind as low pressure is centered over eastern Pennsylvania. The low will move off the east coast tonight into Saturday, but our skies will remain mostly cloudy with a couple of showers. Good air quality is expected to continue into Sunday, then turn moderate Monday out ahead of the next cold front. Here are the forecast details: *** Saturday’s forecast: Mostly cloudy and breezy Saturday with a couple of rain showers likely. Good vertical and horizontal mixing will create an atmosphere that will inhibit fine particle pollution (PM2.5) formation, so concentrations will be on the low side. *** Sunday’s forecast: PM2.5 will be a little higher Sunday with a lighter westerly flow, but with the lack of a strong inversion, concentrations will only average in the high end of the good range. A little sunshine will occur by the afternoon with the mercury flirting with the 50-degree mark. *** Monday’s forecast: A stronger morning inversion Monday may send PM2.5 averages to the moderate threshold. Air quality will improve some during the afternoon as southwest winds increase, and there will be a couple of showers move in as well. *** Extended forecast: Mostly cloudy and breezy Tuesday with a couple of showers still possible but good air quality will return. High pressure brings clouds and some sun Wednesday, then the forecast becomes uncertain for Thanksgiving Day as low pressure may track close enough to us to bring a period of snow turning to rain. Good air quality is likely during the mid-week period, with a possible below normal temperature regime over the remainder of the holiday weekend.---McAuliffe
