NWS saying 64, TWC saying 55.
Models tend to treat Long Island as if it’s a buoy in the Atlantic so I trust the NWS here, the only time Long Island doesn’t keep pace with NYC/NJ is when it’s socked in with clouds/fog.
It’s already 50 under cloudy skies, even if we somehow managed to stay under cloudy skies the whole day we’d likely still go beyond 55.
