Recent atmospheric conditions over southern England, including persistent high pressure and limited Atlantic moisture transport, have produced mostly light or negligible daily precipitation totals in London through mid-October, with only isolated events exceeding 8 mm. Official Met Office guidance and ensemble forecasts indicate continued dry-to-settled patterns over the next 10–14 days, reducing the likelihood of accumulating the 70–90 mm climatological average. These factors have driven trader consensus toward the <35 mm bin as the dominant outcome, while wider ranges reflect uncertainty in late-month frontal systems or any model shifts in steering patterns. Updated National Weather Service and UK Met Office runs expected in coming days will further refine monthly accumulation probabilities.
