Ensemble weather models from NOAA's GFS and ECMWF currently cluster forecasted highs for Chicago's O'Hare Airport on March 25 around 56-58°F, anchoring trader sentiment with 56-57°F leading at 26.5% implied probability amid tight competition from adjacent bins. Recent 00Z model runs indicate a weak upper-level ridge allowing southerly flow and mild advection early in the day, but a developing clipper low pressure system threatens afternoon cooling and clouds, capping peaks below 60°F per NWS Chicago's latest guidance projecting 57°F. Historical March 25 norms hover near 46°F, making this above-average outlook sensitive to boundary layer mixing and any convective interference, with upcoming 12Z updates pivotal for resolution odds.
