Forecast Discussion: Fri : PM2.5 readings are in the teens through much of the Midwest. A low pressure system will track from the Florida panhandle to off the North Carolina coast tonight then race up the coast Saturday. A slight amount of various precip types will fall over Kentucky Friday. A clipper system may bring a little rain and as much as an inch of snow to central Indiana Sunday/Monday. A ridge over the west and a general trough across the eastern US will put us under a strong northwesterly pattern into next week, however that does not always translate into good air quality.
