Official observations from New York City reporting stations, including LaGuardia Airport, recorded a daily minimum temperature of 60–61°F on June 16, 2026, aligning precisely with the market's resolved bracket and reflecting clear overnight conditions that promoted efficient radiative cooling under a stable air mass. This outcome fell slightly below typical mid-June climatological lows near 62–64°F, driven by lighter winds and reduced cloud cover that allowed surface temperatures to drop more readily after sunset. Forecasters from NOAA had highlighted these factors in preceding model runs, with limited spread among guidance supporting the tight temperature range. While post-event verification leaves little room for revision, any discrepancy in station data or measurement timing could theoretically have shifted resolution, though historical consistency in official reports makes such adjustments improbable.
