Forecast Discussion: Current Conditions: As of 2 PM on Monday, mostly cloudy skies prevail over the region as a cold front begins to push eastward toward our area. Right now, very strong southwesterly flow is helping to drive unseasonably warm air into our region. In fact, readings are ranging into the mid to upper 60s across southwestern PA. The wind continues to be the driving factor to high PM 2.5 levels rise. With winds gusting to 50 miles per hour, PM 2.5 concentrations have struggled to make their way out of the good range today. With colder air filtering in tomorrow, expect good air quality to continue to be the rule. *** Tuesday's Forecast: So for Tuesday, a mix of sun and clouds will persist over the region as a cold front pushes through the region early in the day. Prior to the frontal passage, winds will remain out of the south, allowing temperatures to rise into the 40s. Once the front moves through, colder and drier air will begin to drive into the region. As a result, expect afternoon highs to be lower than the morning (with readings probably hovering in the 30s). This new air coupled with the continual strong winds will help to keep PM 2.5 levels confined to the good category. *** Extended Outlook: Over the coming days, expect to see temperatures range much closer to normal early in the period as a result of the col front passage on Tuesday. First, we will have to contend with a winter storm making its way up the eastern seaboard on Wednesday. This system could dump at least a couple inches of snow on the region (more in the more mountainous areas) as it makes its way northeast along the East Coast. Once through, the skies will begin to clear as a new area of high pressure builds in over the northern Plains. This high will swing our winds out of the northwest and drive some colder and drier air into our direction. These conditions are likely to linger through the first half of the weekend as the high shifts east. By the end of the holiday weekend, expect the high to shift out into the Atlantic. As a result, winds will turn southerly and allow temperatures to warm. Overall, air quality levels are expected to remain in the good to moderate threshold during the period. The combination of the area of high pressure moving through the region and a return to southerly flow by the start of the new week will likely force PM 2.5 into the moderate range for a period of time during the next week. --Nolan
