Forecast Discussion: Current Conditions: As of 2 PM on Tuesday, overcast skies prevail over the region as a cold front continues to advance to our east. The frontal system actually passed through our region earlier this morning. The daytime high will likely be in the low to mid 60s but that is not indicative of the temperatures right now. Temperatures have fallen close to 30 degrees from 1 AM this morning thanks to the frontal passage. Right now, strong northwesterly flow is not only dropping temperatures into the 30s but is also creating light snow showers over the area. Needless to say, the strong winds and the influx of cold air into the region are keeping PM 2.5 levels within the good threshold. Expect the good air quality to persist into tomorrow as colder and drier air continues to flood the region. *** Wednesday's Forecast: So for Wednesday, mostly sunny skies will persist throughout the day as an area of high pressure builds in over the Northeastern US. This high will allow the winds to die and temperatures to rebound. Winds will be turning easterly during the day. These winds along with the sunshine are likely to keep temperatures in the upper 40s. The combination of the cool and dry conditions over the region should force PM 2.5 levels to remain within the good category. *** Extended Outlook: Over the coming days, expect to see temperatures remain closer to seasonable levels as a few more disturbances swing through the region. Here is how things are shaping up... On Thursday, expect warmer temperatures to return to the region as the high pressure system, which was over the Northeastern US on Wednesday, moves offshore. The warm conditions will linger into Friday as a new cool front begins to make its way through the Great Lakes / Ohio Valley region. This frontal system is likely to press through later in the day on Friday into Saturday. As it does, we could see a light shower. Otherwise, we will just see cooler and drier air build in for the weekend. Temperatures begin to rebound early next week ahead of a new disturbance over the Ohio Valley. This system could trigger another shower or two late Monday into Tuesday. Overall, air quality levels are expected to remain near the good / moderate threshold. --Nolan
