Latest National Weather Service and AccuWeather model runs position Chicago’s August 25 high near 78–81°F, aligning with the market’s dominant 80–81°F (51%) and 78–79°F (32%) bands. Cooler-than-normal air behind a weak frontal passage and lingering cloud cover have lowered afternoon temperatures several degrees below the 81.5°F climatological normal, while light southwest winds limit lake-breeze moderation. Ensemble guidance shows only modest warming potential if skies clear earlier, supporting the smaller 82–83°F probability. Updated short-range forecasts tomorrow morning and any revisions to boundary-layer moisture will be the next key data points traders monitor before resolution.
