Recent forecasts from the National Weather Service and AccuWeather point to a post-holiday cooldown in Chicago, with northerly flow and increased cloud cover limiting daytime heating after earlier heat. Model consensus favors a daily maximum near 77–80 °F on July 6, consistent with July climatological normals around 84 °F being tempered by the recent frontal passage. Trader emphasis on the 78–81 °F brackets reflects tight model agreement on modest insolation and boundary-layer mixing, while lower bins account for possible persistent stratus or brief showers. Higher outcomes remain low-probability tails tied to faster clearing or stronger southerly return flow. Short-range ensemble spread at this lead time centers on these narrow ranges, with resolution hinging on afternoon observations at official reporting sites.
