Trader sentiment on Chicago's highest temperature April 1 heavily favors 42-43°F at 55.5% implied probability, closely tracking the National Weather Service's latest forecast for O'Hare International Airport projecting a high near 42°F under mostly cloudy skies with a 30% chance of morning showers and light breezy conditions. Persistent overcast cover and northerly winds capping daytime heating, following a cold frontal passage yesterday, have suppressed maxima well below the 53°F climatological normal, with AccuWeather aligning at 43°F high. Ensemble guidance from NOAA models shows minimal divergence, though slight afternoon clearing could nudge toward 44-45°F (10.5%); observations will refine through evening resolution.
