Recent National Weather Service and ensemble model guidance points to a mild overnight period over the Northeast with southerly flow and partial cloud cover limiting radiative cooling, which underpins trader preference for the 66-67°F bin as the most likely minimum in New York City on May 18. Key variables shaping outcomes include boundary-layer moisture levels that could trap heat, sustained wind speeds preventing sharp drops, and any subtle frontal influences that might shift the low by a degree or two. Historical mid-May climatology shows typical overnight minima near 55°F, yet current conditions favor a warmer departure from that baseline. Updated GFS and ECMWF runs expected later today will clarify whether cloud trends or moisture advection strengthen the current consensus or open lower bins.
