Recent National Weather Service and global model guidance indicate that a cool northeasterly flow will bring the lowest temperature in New York City on May 24 into the low- to mid-50s°F range, with ensemble means centered near 53–55°F. This pattern stems from a passing upper-level trough that has replaced the prior warm, southerly regime, allowing maritime air to advect southward while increased cloud cover limits daytime heating and subsequent overnight radiative cooling. Historical May climatology places typical minimums near 58°F, so the current setup represents a modest negative departure. Traders are therefore balancing the tight spread between 52–55°F outcomes against the small but non-zero chance that clearer skies or a slight model shift could push readings into the upper 50s, keeping probabilities closely clustered across the middle buckets.
