National Weather Service point forecasts for Chicago's O'Hare International Airport project a high of 62°F on March 29 under partly sunny skies with south-southwest winds gusting to 25 mph, aligning with GFS and ECMWF ensemble consensus for low-to-mid 60s temperatures that drive the tight race among 62-63°F (26.5% implied probability), 64-65°F (20.5%), and 60-61°F (17.5%). This above-climatological average (~49°F late March norm) reflects southerly warm air advection amid a developing upper-level ridge during neutral-to-weak La Niña conditions, following yesterday's 12Z model runs that trended warmer. Key differentiators include boundary-layer mixing efficiency and mid-level cloudiness: strong insolation and shear favor upper-end outcomes, while increased cloud cover or delayed warming tilts lower; monitor evening 00Z updates for refinements ahead of peak afternoon heating.
