Membury village — best estimate of rain at the village (EA gauge forecasts × on-site calibration)

Weighted composite of the three gauge forecasts above: 0.51·Goren + 0.31·Chards Snowdon Hill + 0.13·Raymonds Hill, fitted 2026-06-10 against the village's own daily gauge (42 months). The village receives ~7% less rain than the raw gauge average. Band edges assume the gauges co-vary (they correlate at r ≈ 0.95); no exceedance table here because threshold probabilities don't combine across gauges.

5.5 mm total (sum of hourly medians) · wettest hour : 0.2 mm/h (80% band 0.0–1.0) · 36% chance of any rain in the peak hour
