The National Weather Service's latest forecast pins Chicago's high temperature on March 20 at 70-71°F, aligning with ensemble model outputs from GFS and ECMWF that show consistent mild conditions driven by a ridge of high pressure over the Midwest and southerly winds transporting warmer air from the Gulf. Historical March data supports feasibility, with rare but precedented warm outliers amid a warming climate trend, though baseline averages hover near 45°F. Trader consensus at 100% reflects this convergence, with minimal volatility in recent runs. Realistic challenges include a sudden shift in the jet stream ushering Arctic air or model overestimation of cloud cover, potentially dropping highs to the 60s°F.
