Convective available potential energy
Some may be stuck in the clouds for much of the day. On the Cape there is sunshine! A gorgeous morning. I do expect a gradual thinning and lifting to the clouds for partial sun to emerge by the late morning into the early afternoon. I think we are looking at a decent beach day for sky conditions, once the clouds burn off, but wind and waves may be another issue. Any emerging sun will help to fuel the development of afternoon storms.
