Marine layer keeps most of Jersey Shore cool and cloudy today

    If you’re inland, it’s sunny and warm.

    At the coast? Cool, damp, and cloudy. 

    What gives?

    It’s the result of the onshore flow delivering a marine layer, which is defined as “an air mass which develops over the surface of a large body of water such as the ocean or large lake in the presence of a temperature inversion.”

    Coastal residents know that as temperatures warm during the afternoon, marine layers are usually “burned off.”

    Current satellite imagery indicates that layer near the coast has been slowly diminishing this afternoon.
