Met Office forecasts indicate sunny conditions for London on April 7, with highs clustering around 18-20°C under building high pressure following Storm Dave's clearance, driving trader sentiment toward these outcomes at 32%, 27.5%, and 17.5% implied probabilities respectively. Ensemble model consensus from ECMWF and GFS supports warm sunshine after a chilly start with patchy frost, but differentiates the leaders through subtle variations: 18°C reflects potential thin high cloud muting peak insolation, 19°C aligns with baseline clear-sky heating, and 20°C accounts for urban heat island amplification at key stations like Heathrow. Early April climatology averages 13°C highs, marking this as anomalously mild; new model runs overnight and hourly observations will refine the peak before resolution.
