Sunday will feature increasing cirrus, as high lvl moisture is drawn northward from ts bonnie. The increasing clouds will hold temps down a bit, but enough heating/destabilization is expected to lead to isolated/scattered pm convection popping off along the spine of the Alleghenies. All 00z guidance now pointing toward a dry day across the se counties beneath ridging and assoc lg scale subsidence.
