Recent National Weather Service and NOAA model consensus points to a mild overnight period across the New York City metro area on May 18, with light southerly flow and elevated dew points limiting radiational cooling and supporting a lowest temperature in the 66–67°F range. This aligns with the market’s strongest implied probability at 43.5 percent, as current atmospheric conditions favor warmer-than-normal minima compared with the mid-May climatological baseline of roughly 55°F at Central Park. Ensemble guidance shows limited spread, though any unexpected increase in cloud cover or wind could nudge readings slightly lower into the 64–65°F bin, which traders price at 16.5 percent. Official resolution will rely on verified observations from LaGuardia Airport, with final confirmation expected by midnight local time.
