How does a winter snow storm or nor'easter affect Long Island differently by region?

Why does islandwide weather vary between the North Shore, the Hamptons, and Nassau County?

Islandwide weather on Long Island is shaped by surrounding maritime waters. Long Island Sound moderates North Shore towns like Port Jefferson, the cold Atlantic Ocean cools the Hamptons and Montauk, the Central Pine Barrens creates extreme radiational frost hollows in Westhampton, and western Nassau experiences urban heat island effects from NYC.
