Polymarket traders assign a 47.5% implied probability to a 10°C high in Paris on March 26, with 35% on 9°C, driven by the latest ECMWF and Météo-France ensemble forecasts converging on 9-10°C amid a high-pressure ridge ushering cool, stable continental air from the north-northeast. Recent 48-hour model runs refined this outlook, incorporating increased low-level cloudiness and light winds that cap daytime heating, shifting odds away from prior 11°C scenarios (now 14.5%). Spring's low solar angle and shallow boundary layer further constrain warming potential, aligning with climatological March highs near 11°C but tempered by current jet stream positioning. Daily forecast updates from European models tomorrow could adjust these trader sentiments given inherent short-range uncertainties.
