Trader consensus on Polymarket tilts slightly toward a 14°C high in London today, reflecting the Met Office's latest morning update forecasting 14°C at Heathrow under largely dry conditions with bright or sunny spells and lighter scattered showers than yesterday. BBC Weather models a 13°C peak amid light rain showers and north-north-westerly breezes, highlighting the razor-thin margin driven by cloud cover variability and shower timing—persistent morning overcast could cap temperatures at 13°C, while afternoon sun breaks enable 14°C. Northerly winds maintain cool air masses below May climatological norms of 17–18°C, with hourly observations from official stations determining resolution amid inherent short-range forecast uncertainty; monitor Met Office updates through afternoon peak heating around 3–5pm.
