Recent early June rainfall in London has pushed monthly totals toward or slightly above the 43–60 mm historical average, yet a shift toward settled high-pressure conditions and reduced Atlantic low activity is now favoring drier outcomes for the remainder of the month. Met Office and other model guidance point to a northwest-southeast split with limited showers, lowering the chance of heavy accumulations while still allowing variability from lingering fronts. This equilibrium among the 50–60 mm, 60–70 mm, and 70–80 mm buckets reflects trader assessment of forecast uncertainty in jet-stream positioning and precipitation efficiency over the final two weeks. Positive NAO-like patterns historically correlate with below-normal totals, but any model shift toward stronger westerlies could add 10–20 mm and favor the upper buckets.
