Trader sentiment clusters around 8-10°C for London's highest temperature on March 26, driven by the Met Office's latest forecast indicating a cloudy day with rain, capping highs near 9°C under persistent low pressure from the Atlantic. Ensemble models from ECMWF and UKMO show a tight spread of 7-11°C, reflecting uncertainty in cloud cover and frontal timing that could suppress or allow brief sunny intervals for slight warming. Historical March 26 averages hover at 11°C, but this year's jet stream dip favors cooler outcomes, with 9°C edging ahead as implied probabilities align with verified soundings and recent sounder data. Monitor hourly updates from Heathrow observations for resolution shifts.
