National Weather Service forecasts for Chicago point to a high temperature of 78°F or warmer on May 18, driven by southerly flow advecting warm, moist air from the southern Plains beneath a strengthening high-pressure ridge. Multiple model runs, including the latest GFS and ECMWF guidance, show minimal cloud cover and daytime heating pushing readings into the upper 70s to low 80s, well above the city’s historical May 18 average near 70°F. This consensus supports the market’s dominant implied probability for the upper bracket while leaving room for minor revisions if overnight model trends shift. Traders will watch the next official forecast update for any changes in the thermal profile or wind direction that could alter peak readings.
