Trader consensus on Polymarket overwhelmingly favors a high temperature of 56°F or higher in Chicago on May 14 (99.5% implied probability), driven by the National Weather Service Chicago's latest forecast discussion issued early May 13, which projects highs in the 60s to low 70s inland and 50s to near 60°F along Lake Michigan shores under a moderating airmass following a recent cold frontal passage. Model consensus reflects a building surface high-pressure ridge promoting light winds, clearing skies, and radiational warming after yesterday's cooler conditions, aligning with May 14 climatological normals of 69.9°F high. Easterly onshore flow may cap lakefront readings near 60°F, but scenarios challenging 56°F—like unexpectedly stronger lake breezes or persistent low clouds—remain low-probability per current guidance. Next NWS updates this afternoon could refine details ahead of resolution at official observing sites.
