**Latest National Weather Service guidance and ensemble forecast models like GFS and ECMWF project Chicago's high temperature on March 29 clustering in the low-to-mid 60s°F**, aligning with trader consensus favoring 62-63°F (28.5% implied probability), 60-61°F (22.5%), and 64-65°F (20.5%). This above-normal warmth—exceeding the late-March climatological average of 48°F—stems from a warming trend following a chilly March 28, driven by southerly winds ushering a milder air mass amid neutral-to-weak La Niña influences. Differentiating factors include model spread on peak afternoon heating, potential for partial cloud cover limiting insolation, and diurnal temperature cycles, with genuine uncertainty reflected in tight odds; traders eye evening 12z model runs and NWS updates for refinement before resolution at Chicago O'Hare.
