Recent National Weather Service and AccuWeather guidance projects Chicago’s overnight low for August 23 near the 1991–2020 normal of 64 °F, with model ensembles clustering between 62–68 °F. This consensus underpins the tight market distribution around 58–63 °F bins. Primary drivers include clear to partly cloudy skies favoring radiational cooling after sunset, light northwesterly flow limiting warm-air advection, and Lake Michigan’s moderating influence on boundary-layer temperatures. Minor differences among leading outcomes hinge on forecast timing of any weak frontal passage, variations in low-level moisture and mixing depth, and localized urban heat-island effects, all of which can shift the minimum by 2–4 °F. Updated model runs and NWS evening discussions will refine these variables ahead of resolution.
