Current Conditions (Friday afternoon, 11/6/2026): A reinforcing cold front is currently located in central Pennsylvania. It will pass through eastern Pennsylvania by this evening, bringing much cooler air with increasing winds out of the west. This should bring good air quality for fine particulate matter (PM2.5) tonight. *** Saturday’s Forecast: Saturday will be breezy and much cooler with a mixture of sunshine and clouds. Westerly winds may occasionally gust to 20 mph. This wind in the lower levels of the atmosphere will prevent pollutants from building up, leading to good air quality. *** Sunday’s Forecast: Expect sunny and breezy conditions. The wind may occasionally gust 10 to 20 mph. The air quality should remain good. *** Monday’s Forecast: Sunshine and a breezy westerly wind will continue Monday with good air quality for PM2.5. *** Extended Forecast: Dry weather is anticipated through the middle of next week with mainly good air quality for PM2.5. The steady wind will prevent pollutants from building up each day. – Curtis
