Forecast Discussion: Current Conditions: As of 2 PM on Tuesday, mostly cloudy skies prevail across the region as a cold front makes its way through western PA. Right now, winds continue to blow out of the west, resulting in an influx of warmer air into the region. In fact, temperatures are rising into the upper 60s. There is even a line stronger storms making their way into the region just in advance of the front. The influx of warm and moist conditions into the region earlier today helped to drive PM 2.5 levels into the moderate range. Expect a cleaner air mass to move in tomorrow as cooler, drier air returns. *** Wednesday's Forecast: So for Wednesday, partly sunny skies will persist across the region as the cold front which pressed through the region on Tuesday, continues to move off to our east. On the backside of the front, winds will remain relatively strong as they turn more out of the north. The northerly flow will tap into the air mass which has been over Canada. Therefore, expect temperatures to be cooler and the air mass to be drier. High temperatures are only expected to make their way into the low 50s. The combination of these factors (along with the winds) are likely to keep PM 2.5 levels from rising out of the good category. *** Extended Outlook: Over the coming days, expect to see temperatures remain at to below normal as a series of storm systems push through the region. Here is how things are shaping up... For the second half of the week, expect a warm up to occur as a ridge of high pressure tries to reestablish itself over the eastern US. At the same time, a new storm system will begin taking shape over the Plains. This system is slated to slide east during the week and is likely to impact our area on Friday. As it passes through, expect rain to develop over the area. Once it passes off to our east, drier weather will settle in for the weekend over our area. On the other hand, the Plains will once again be wet as a new storm system begins to develop. Like its predecessors, this storm system is slated to push east. In fact, it is likely to impact our area in the Monday / Wednesday time frame. As it moves in, expect rain to develop over the region (and it is likely to continue off and on early in the week). Once it does make its way through, expect cooler and drier air to settle back into the region. Overall, air quality levels during the period are expected to remain in the good range. Brief periods of moderate conditions are likely when the temperatures warm and the air is humid (like the Saturday / Sunday time frame this weekend). --Nolan
