Forecast Discussion: Current conditions: At 2 p.m. EST this Friday afternoon, high pressure to our north has driven colder air southward into Pennsylvania, with temperatures 20 degrees colder than Thursday's readings. Mixing has also increased from the north and northwest, leading to good air quality. Tonight will start out clear, but clouds will increase and thicken later on. *** Saturday's forecast: Overcast and cold for the day Saturday with a stationary front located just to the south. Snow, sleet, and light freezing rain will break out across our area Saturday afternoon and evening. A coating to as much as an inch of snow and sleet will accumulate from this event. High temperatures will struggle to reach the freezing mark, and with little mixing, fine particulate will increase to moderate levels. Turning out partly cloudy Saturday night with lows falling back to the middle 20s. *** Sunday's forecast: Seasonably cold with some sunshine returning on Sunday as the nearly stationary frontal boundary creeps further southward into Virginia. Temperatures will max out close to 40 degrees, and with a little more wind blowing, PM2.5 will improve to the good range. *** Monday's forecast: More clouds will move back in for the day Monday with a bit of sleet and freezing rain possible. *** Tuesday's forecast: Turning a little milder Tuesday with a more humid southerly flow along with a couple of showers late in the day and at night. Temperatures could rise to the lower 40s by nightfall, but light mixing and high moisture content may spell another day of moderate PM2.5. *** Extended forecast: The middle to latter part of the week will be a mostly dry and mild one, with temperatures averaging several degrees above normal. Increasing westerly winds Wednesday into Thursday will bring back good air quality with perhaps some sunshine each day.---McAuliffe
