Daily Air Quality Forecast for Unionville, Pennsylvania

Current Conditions: At 3 p.m. EST this Friday afternoon, areas of rain are moving through the area. A light south wind along with the rain has kept fine particle (PM2.5) concentrations down inside the good range. Good air quality continues Saturday, then turns into the moderate threshold Sunday into Monday as milder air makes inroads into western Pennsylvania. Here are the forecast details: *** Saturday's forecast: Turning out partly sunny Saturday with a cold north wind keeping temperatures from rising out of the middle 20s and wind chills down to 10 above. On the plus side, air quality will be in the good range. *** Sunday's forecast: Mostly cloudy Sunday and not as cold but with a couple of rain and snow showers as low pressure passes just to the north. Lighter surface flow will cause PM2.5 to rise to low moderate. *** Monday's forecast: Moderate PM2.5 concentrations will continue Monday with a mostly cloudy sky, light southwest winds, and highs in the middle 40s. *** Extended forecast: Colder Tuesday with times of clouds and sunshine--air quality will improve to the good range. The pattern turns unsettled during the middle of the week with rain and rain showers. Temperatures may reach near 50 degrees Thursday out ahead of the next cold front. Air quality will range from the upper good to lower moderate range during the mid-week period. Turning colder once more by week's end.---McAuliffe
