Daily Air Quality Forecast for Unionville, Pennsylvania

Current Conditions: At 3 p.m. EST this Wednesday afternoon, skies are mostly cloudy with fine particle (PM2.5) concentrations well down in the good range. The pattern will be an active one over the next several days as a couple of systems are expected to affect the area, one tonight into early Thursday, and the other over the weekend. Here are the forecast details: *** Thursday's forecast: Precipitation will end early Thursday as a bit of rain as low pressure moves off to the east. Lighter surface flow will allow for a PM2.5 increase, but air quality should stay in the upper good range. High temperatures will reach the middle 40s. *** Extended forecast: Breezy and colder Friday with times of clouds and sunshine and lowering PM2.5 values. Highs will struggle in the upper 20s. The next system affects us late Saturday and Saturday night with a mix of snow, sleet, freezing rain and plain rain. High pressure builds in with seasonably cold conditions Sunday into Monday, then another system may track just to the southeast to bring a bit of snow by the middle of next week. Air quality will be in the upper good to perhaps lower moderate range over the weekend into Monday.---McAuliffe
