Trader consensus on Polymarket heavily favors a high of 11°C (51.5% implied probability) in Warsaw on March 21, driven by the latest ECMWF and GFS ensemble forecasts projecting mild advection of Atlantic air masses into Central Europe, with daytime highs clustering at 10-12°C amid light southerly winds and partial cloud cover. Recent IMGW observations show Warsaw's temperatures rising from sub-5°C lows earlier in the week, aligning with a broader spring warming trend that has pushed anomalies 2-3°C above the 1991-2020 March average of ~9°C. Lower odds for extremes reflect low model spread and minimal risk of cold snaps or heat surges, with official airport measurements set to resolve the market.
