Trader consensus overwhelmingly favors a Chicago high of 70-71°F on March 20, driven by high-resolution forecasts from NOAA's GFS and ECMWF models converging on peak afternoon temperatures in this narrow band amid a persistent upper-level ridge amplifying warm southerly flow. Verified short-range guidance from the National Weather Service Chicago office reinforces this, with deterministic runs showing minimal spread and dewpoints supportive of highs just shy of advisory thresholds. Historical March norms hover near 45°F, underscoring the anomaly, yet ensemble probabilities exceed 90% for this outcome. Realistic challenges include a late-developing cold front or amplified lake-effect moderation from Lake Michigan, though current soundings suggest low likelihood before midnight resolution.
