Current precipitation totals in London stand well below the long-term May average of 45–55 mm, with only around 5 mm recorded through mid-month amid persistent high-pressure dominance and limited frontal activity. Ensemble forecast models from the Met Office and ECMWF show mostly dry conditions through the final two weeks, with scattered showers possible but low probability of widespread rainfall exceeding 10–15 mm. This setup keeps the 25–30 mm and 15–20 mm bins nearly tied in trader sentiment, reflecting genuine uncertainty over whether late-month instability will deliver enough additional accumulation to reach the higher range or leave totals in the drier 10–20 mm cluster. Updated model runs and any shift toward Atlantic low-pressure systems could quickly alter the distribution before month-end.
