National Weather Service forecasts from NOAA position Chicago's highest temperature today around 48-49°F, aligning with the market's leading 35.5% implied probability as traders aggregate the sunny conditions and north-northwest winds of 5-10 mph ushering in cooler post-frontal air following recent severe thunderstorms on Thursday. Model consensus from recent runs shows limited daytime heating under mostly clear skies, with overnight lows near 28°F capping peak warmth in the upper 40s, consistent with March 28 climatological normals of 52°F but moderated by the current continental polar air mass. Uncertainties remain in exact boundary layer mixing and urban heat effects, with official observations from O'Hare or Midway resolving the market; hourly updates could refine trader sentiment as the day progresses.
