Latest National Weather Service guidance and ensemble model runs point to a high near 79–80°F in New York City on July 23, supported by mostly sunny skies, light northwest flow, and limited moisture return behind recent frontal passage. Traders assign nearly 70% combined probability to the 78–81°F bins because short-range models show only modest afternoon warming before any sea-breeze or thin cloud deck develops. Historical July climatology favors highs around 82°F, yet the current pattern’s cooler mid-level temperatures and drier boundary layer keep readings below seasonal norms. Key uncertainties remain the precise timing of any late-day increase in cumulus and the strength of onshore flow, both of which could shift the daily maximum by 1–2°F and explain the tight spread between the two leading outcomes.
