Trader sentiment on Chicago's highest temperature March 22 heavily favors 63°F or below at 59% implied probability, driven by the latest National Weather Service forecasts and ensemble model outputs from GFS and ECMWF predicting mild highs in the upper 50s to low 60s amid a cool post-frontal air mass. Recent 12z model runs show convergence on partly cloudy skies with northwest winds capping warmth, reducing odds for 64-65°F (22.6%) while extreme outliers like 82°F+ (0.8%) reflect rare historical warm anomalies but clash with current jet stream patterns favoring cooler Canadian air. Historical March 22 averages hover near 48°F, reinforcing model conservatism against upside risks from any unexpected ridging. Key watch: evening forecast updates could shift probabilities if southerly flow strengthens.
