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.

Dry day expected. Peak chance of any rain: 11% at .
