Traders' close split between 40-41°F and 42-43°F reflects National Weather Service forecasts showing Chicago's high temperature hovering near 41°F on March 27, driven by a cool post-frontal air mass from recent Midwest low pressure systems, partial cloud cover limiting solar heating, and light southerly winds capping highs below 45°F. Ensemble model runs from GFS and ECMWF indicate low confidence in fine-scale differentiation, with spread due to varying cloud timing and boundary layer mixing over urban O'Hare International Airport, the resolution site. Climatologically, late March averages 44°F, but this system's subsidence suppresses warmth; watch afternoon NWS updates and 12z model refreshes for shifts ahead of the event.
