Latest National Weather Service forecasts for Chicago's O'Hare Airport, the probable measurement site, project a high near 42°F on March 27, fueling trader preference for 42-43°F (24%) over 40-41°F (21.5%), with ensemble models like GFS and ECMWF converging on mid-40s amid lingering cold air and light southerly winds. Key differentiators include timing of diurnal heating and cloud cover: earlier clearing could push peaks to 42-43°F by allowing stronger insolation, while persistent low stratus might cap at 40-41°F, consistent with 3-5°F spreads in late-March historical analogs averaging 41°F. Odds remain tight pending 00z model runs and any pre-dawn observations.
