Current Conditions at 2 p.m. EST this Thursday afternoon: Skies are cloudy to at times partly sunny across the region as an Arctic cold front sweeps through central Pennsylvania. Fine particle (PM2.5) concentrations have dropped some over the past couple of hours, but overall averages today will remain moderate. Low moderate PM2.5 levels are likely Friday, then higher PM2.5 will occur over the weekend with slightly milder air and less mixing. Here are the forecast details: *** Friday’s forecast: Mostly cloudy and cold Friday. Low pressure tracking well to the south will not result in any snowfall locally as temperatures hold near the 30-degree mark. PM2.5 will average in the lower moderate range in parts of the area. *** Extended forecast: Light winds and morning inversions will contribute to higher PM2.5 readings Saturday and Sunday. Middle to upper moderate PM2.5 averages are likely, with the highest concentrations coming late Saturday night into early Sunday. It will be slightly milder over the weekend as highs move close to 40 degrees. The next cold front comes through Sunday night with a few snow showers, then another shot of cold air follows the front Monday and Tuesday. Good air quality will prevail.---McAuliffe
