Trader consensus on Polymarket tilts toward a 5°C overnight low at Paris-Le Bourget Airport on May 15 (35.5% implied probability), driven by Météo-France's latest guidance projecting 4–7°C minima amid persistent northerly winds, cloudy skies, and light showers suppressing daytime highs to 13–16°C. This anomalously cool mid-May pattern—well below the 9–10°C climatological average—stems from a stalled low-pressure system over northern France, enhancing radiative cooling potential under partial clearing. Differentiating factors include ensemble model spreads: ECMWF leans cooler at 4°C with drier conditions overnight, while GFS holds nearer 6°C with lingering clouds; urban heat island effects may nudge urban readings higher. Watch 12z model runs today for refinements ahead of resolution.
