Latest National Weather Service guidance and GFS/ECMWF ensemble models project a high temperature near 62°F at Chicago O'Hare International Airport on March 29, aligning with trader consensus favoring the 62-63°F bin at 26.5% implied probability amid clustered 60-65°F outcomes. This above-normal outlook, exceeding the late-March climatological average of 49°F under neutral-to-weak La Niña conditions, stems from southerly winds advecting milder air masses beneath a developing upper-level ridge, following cooler 44-50°F readings on March 27-28. Key differentiators include boundary-layer mixing efficiency and mid-level cloud cover: robust insolation and strong vertical mixing could push toward 64-65°F, while increased clouds or delayed advection favor 60-61°F. Traders monitor today's 00Z model runs for refinements ahead of afternoon peak heating.
