The National Weather Service forecast drives trader consensus toward a Chicago O'Hare high temperature of 48-49°F (37% implied probability), reflecting sunny conditions and light north-northwest winds around 10 mph following a post-frontal cold air mass with overnight lows near 28°F. Clear skies enable solar heating from sunrise at 6:41 AM CDT, but persistent cool upper air limits peaks below the March 28 normal of 51.7°F, with model ensembles like GFS clustering tightly nearby. Adjacent outcomes at 46-47°F (21%) and 50-51°F (21.5%) capture uncertainty in afternoon maximums around 2-4 PM, as real-time ASOS observations at KORD track progress toward evening sunset at 7:13 PM CDT.
