Trader consensus on Polymarket tilts toward a high of 11°C (30.5% implied probability) in Paris on March 28, closely trailed by 12°C (23.5%) and 10°C (22.5%), reflecting the latest ensemble forecasts from ECMWF and GFS models, which cluster daytime highs around 10-12°C amid a stable high-pressure ridge over Western Europe. Météo-France's most recent guidance points to mild spring conditions with light southerly winds and partial cloud cover limiting extremes, following a pattern of near-normal temperatures after recent Atlantic frontal passages. Key differentiators include potential for brief afternoon clearing boosting 12°C odds versus increased overcast capping at 10°C; daily updates from European model runs expected within 24 hours could refine this tight race, underscoring inherent short-range forecast uncertainty.
