Forecast Discussion: Current Conditions: As of 2 PM on Wednesday, mostly cloudy skies prevail over the region as a weak disturbance continues to swing through the New England states. Right now, strong westerly wind along with the light snow is reducing visibility while limiting temperatures to low 20s. The combination of the strong winds and the cold temperatures are helping to hold PM 2.5 levels near the good / moderate range. Expect the good air quality to persist into tomorrow as conditions remain cold and dry. *** Thursday's Forecast: So for Thursday, a mix of sun and clouds will persist during the day as the disturbance over New England continues to pull away from the region. At the same time, a new area of high pressure will build in over the Midwestern US. The combination of the departing storm system and incoming high will help to steer our flow out of the northwest. The northwesterly flow will, in turn, force colder, drier air to build southward over the region. Overall, temperatures will remain in the 20s. With strong winds allowing a continental Canadian air mass to build in, expect PM 2.5 levels to remain limited to the good threshold. --Nolan
