National Weather Service guidance and 12z GFS/ECMWF ensemble means project a high near 62°F at Chicago O'Hare International Airport on March 29, fueling trader consensus with 62-63°F leading at 25% amid mild south-southwesterly winds around 10 mph advecting warmer Gulf-sourced air masses under partly sunny skies. This rebound from recent cool-downs—highs of 44-45°F on March 27 and 49°F on March 28—exceeds the late-March climatological average of 52°F during neutral-to-weak La Niña conditions. Tight odds across 58-65°F reflect uncertainty in boundary-layer mixing and low-level stratus persistence; fuller afternoon clearing could enhance solar heating to 64-65°F, while lingering clouds might cap peaks at 60-61°F. Traders eye 00z model runs and NWS updates for refinements before resolution.
