Trader sentiment clusters around 15°C (30.5%) and 14°C (26.0%) for London's highest temperature on March 24, propelled by the latest Met Office and ECMWF ensemble forecasts indicating peaks of 14-16°C under a developing high-pressure ridge ushering mild southwesterly flows from the Atlantic. This edges out 16°C (19.5%) and cooler options amid low model spread for mid-teens highs, contrasting historical March 24 averages near 12°C, with minimal risk of Arctic air per current jet stream undulation over Scandinavia. Subtle cloud cover variability and urban heat effects could tip outcomes, but 76% market-implied odds favor 14-16°C; monitor noon model refreshes for shifts in convective potential.
