Not sure what you mean by the “marine layer”, but it sure appears that there is a concentration of unusually hot water in the Chesapeake bay region.

The Chesapeake Bay area is actually very cold. They use the same color on both ends of the chart. Probably cooled from the Arctic Air. Just watch, that bright pink cold area will expand dramatically and may eventually show up in the Gulf. That is what happened in the Southern Hemisphere last winter. And the summer sun is not making those cold pink spots warm down there. Do not know what the heck is going on in that warm spot in the center of Southern Pacific Ocean. It developed after the cold spots now located near New Zealand and South America developed. Probably due to some very large current eddies. But as one famous scientists kinda once said, for every action there is an equal and opposite reaction.
