Recent National Weather Service and model guidance highlight increased cloud cover and thunderstorm chances as the main driver keeping Chicago's August 13 high temperature outlook centered in the mid-70s. A pattern favoring rounds of showers has reduced daytime heating potential compared with seasonal normals near 83°F, with consensus forecasts clustering around 76–79°F. This aligns closely with market-implied odds favoring 76–77°F at 29% and nearby bins, reflecting traders' assessment of ensemble spread and the narrow window before resolution. Key variables include steering flow strength and any late-day clearing that could allow brief warming spikes into the low 80s. Updated NWS briefings and model runs expected overnight will provide the final calibration ahead of the daily maximum.
