Forecast Discussion: Current Conditions: As of 2 PM on Tuesday, mostly cloudy skies prevail over the region as an upper level trough remains entrenched over the Northeastern US. Right now, a surface area of high pressure continues to reside over the Plains / Midwestern US region. The clockwise flow around the high are keeping our winds northwesterly today. Therefore, cooler and drier air continues to infiltrate the region. Temperatures are currently hovering in the low to mid 60s. The cool and dry conditions along with the cloud cover are holding air quality levels back in the good range. Expect the good air quality to linger into tomorrow as a weak disturbance swings through the region. *** Wednesday's Forecast: So for Wednesday, mostly cloudy skies will continue to persist over the region as a disturbance swings through the Great Lakes region and toward our area. By the afternoon, this disturbance will trigger shower development over portions of western PA. Westerly winds will prevail for much of the day. Even with the cloud cover and afternoon rain chances, high temperatures are expected to reach into the low 70s. The clouds and rain will limit ozone formation to the good range. PM 2.5 levels should remain in the upper good range as moisture levels begin to increase. *** Extended Outlook: Over the coming days, expect temperatures to remain below normal as the overall weather pattern remain more wet than dry. Here is how things are shaping up... On Thursday, expect cloudy skies to persist over the region as the core of the cold air, which has resided over the Northeastern US since the frontal passage late on Sunday / early on Monday, will begin to track back into eastern Canada. At the same time, our winds will swing more out the south and west. The southwesterly winds will tap into more moisture residing over the southeastern US. Peaks of sunshine during the day should help trigger instability during the afternoon hours. Therefore, expect the chance for showers to persist over our area from Friday through Monday. The cloud cover and rain showers should limit ozone formation but should be very conducive for PM 2.5 formation. Therefore, expect PM 2.5 levels to creep into the moderate range as early as Thursday (and likely extending right through the weekend). Expect some clearing toward the middle of next week, which could force ozone back into the moderate range as well. --Nolan
