Trader consensus on Polymarket closely mirrors the latest Environment and Climate Change Canada (ECCC) forecasts for Toronto's March 28 high temperature, with ensemble model runs from GEM, GFS, and ECMWF showing a tight 2–4°C range amid lingering late-winter chill. A deep upper-air trough over central Canada is funneling polar air masses across the Great Lakes, capping highs below seasonal norms of 5–7°C, while variable low-level cloud cover and urban heat island effects in Toronto create the fine differentiation between leading outcomes at 3°C (26.5%) and 2°C (24.5%). Light southerly winds could boost peaks slightly above model means near 2.5°C, but genuine uncertainty persists until 00z updates refine boundary layer forecasts and lake-influenced moisture. Hourly observations will resolve the market as the date unfolds.
