Recent NOAA and NWS guidance highlights a late-June heatwave building across the eastern U.S., with New York City overnight lows expected in the upper 60s to low 70s as warm, humid air advects northward ahead of stronger high pressure. Model consensus favors limited overnight radiative cooling under partly cloudy skies and light winds, keeping the daily minimum near 68–71 °F. Small differences among leading bins reflect uncertainty in boundary-layer moisture and any weak frontal timing that could enhance or suppress cooling by a degree or two. Updated 24 June outlooks reinforce above-normal temperatures, tightening trader focus on this narrow range while leaving room for minor forecast revisions before the 26th.
