Forecast Discussion: Current Conditions: As of 2 PM on Wednesday, overcast skies continue to persist over the region as a frontal system remains draped across the Mid-Atlantic. Right now, temperatures have cooled into the mid 30s as rain continues to filter in from the west. Expect this rain to change over to snow later in the day as even colder air filters in. Air quality levels have lowered into the good range as the colder air begin to filter in earlier today. As even colder air moves into our area tomorrow, expect air quality levels to remain within the good threshold. *** Thursday's Forecast: So for Thursday, mostly cloudy skies will continue to persist as the frontal system, which slowly dragged off to our south and east on Wednesday, continues its lethargic progression eastward. As a result, we could see some linger snow early in the day, before conditions begin to clear during the afternoon. A consistent northwesterly wind will keep afternoon highs near the 20 degree mark. In addition, an increasingly dry air mass will build in during the second half of the day. As a result of the colder and drier air mass building in (along with the moderate northwesterly flow), PM 2.5 levels will stay confined to the good category. *** Extended Outlook: Over the coming days, expect temperatures to remain cold early in the period thanks to an area of high pressure moving in over the Plains. This high will gradually shift east over the weekend. By the end of the weekend, the high will begin to position itself across the Mid-Atlantic. This will lead to lighter winds, warmer temperatures and deteriorating air quality over our area. A seasonably warm air mass will finally move during the first half of next week. As it does, expect PM 2.5 levels to remain elevated in the moderate range. --Nolan
