National Weather Service forecasts and ensemble guidance from GFS and ECMWF models indicate a high temperature near 62°F at Chicago O'Hare on March 29 under partly sunny skies with light southwesterly winds of 5-10 mph, driving trader consensus toward the closely bunched 60-65°F outcomes amid warm air advection ahead of a developing upper-level ridge following March 28's cooler 49°F maximum. This setup exceeds the March 29 climatological normal of 52°F during a neutral-to-weak La Niña pattern, but inherent short-range uncertainty—stemming from variable cloud cover timing, precise ridge amplitude, and boundary-layer mixing—differentiates the leading 62-63°F (28.5% implied probability) from slightly warmer 64-65°F or cooler 60-61°F bins. Traders eye evening 00Z model updates and morning observations for potential shifts before resolution.
