Latest Met Office and BBC Weather forecasts project a high of 14-15°C at London City Airport on April 1 under overcast to light cloud conditions with light north-westerly winds, driving the near-even trader split between these outcomes on Polymarket. Ensemble model consensus from ECMWF and GFS centers probabilities in the 13-15°C cluster, reflecting yesterday's sunny intervals on March 31 transitioning to increased cloud cover that tempers solar heating. Differentiating factors include potential afternoon brightening for a 15°C peak versus persistent overcast holding at 14°C, against early-April climatological averages of ~13°C boosted by urban heat island effects. Resolution hinges on finalized Wunderground observations by evening, amid inherent short-range forecast uncertainty.
