Fun meteorology lesson of the day:
When you hear “cold front” you assume it will get colder after it passes through. Yet, Long Island’s temperature *went up* after the cold front once the wind changed from SW to NW.
So how does it get *warmer* after a *cold* front?

Comments
The air mass aloft was very warm — but in Long Island, southwesterly wind is onshore flow, and water temperatures are still quite chilly. So the 0z sounding shows a near surface inversion:
This accompanied a change in wind direction to the NW, which is offshore flow.
Places like Long Island & Cape Cod can warm up behind a cold front thanks to their surrounding geography & proximity to the ocean.
