Northern Allegheny County had a deficit carbon balance early in the week, most likely due to clouds with rain showers, but looks to get to a surplus in projected reports with increasing sun the next two days. Juniata County also had a deficit although not very deep with a projected surplus through the next few days. Southeastern Berks did not have the deficit that other areas had this week and also looks to have a surplus heading into the weekend. Erie has been running surplus carbon all week and is projected to continue.
