Trader consensus favors a high of 56°F or higher in Chicago on March 24 at 43% implied probability, driven by the latest NOAA Weather Prediction Center guidance and model ensembles like GFS and ECMWF, which project mid-50s peaks amid a building upper-level ridge ushering warm air advection from the south. This marks a recent upward shift from earlier cooler outlooks, fueled by March 22 model runs showing reduced cold air influence and strengthening southerly winds. Historical March norms hover around 45°F, but current soil temperatures and minimal snow cover support faster warming; official NWS point forecast aligns at 55°F, with 54-55°F bins at 22% reflecting ensemble spread and typical diurnal variability at O'Hare. Uncertainty persists from potential cloud cover modulating insolation.
