National Weather Service forecasts indicate a high near 50°F for Chicago on March 28 under mostly sunny skies with northwest winds of 10-15 mph, anchoring trader consensus around the closely matched 48-51°F range at over 47% combined implied probability. Recent model runs from GFS and ECMWF show minimal spread, with peaks between 48-52°F, reflecting a building upper-level ridge moderating earlier-season chill but capping significant warming. Differentiating factors include potential afternoon cloudiness reducing peak insolation and exact timing of diurnal heating at O'Hare International Airport, the market's measurement site—late-day gusts could trim 1-2°F from maxima. Late March climatology averages 46°F highs, making this mild but uncertain outlook hinge on final hourly observations.
