National Weather Service forecasts project a high temperature near 56°F at Chicago O'Hare International Airport today under partly sunny skies, with northeast winds around 10-15 mph moderating lake influence after a recent cool front. This model consensus from short-range guidance like the High-Resolution Rapid Refresh aligns morning observations in the low 50s°F with expected peak afternoon heating, yielding 99.5% trader-implied odds for 56°F or higher. Historical May diurnal swings of 8-12°F from similar starts bolster confidence, far exceeding the 70°F climatological normal amid lingering cool-season patterns. Scenarios challenging this include unforecasted marine stratus persistence or gusty cold advection, though current satellite imagery shows clearing trends; monitor hourly updates through 4 PM CDT for resolution.
