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 11Z .
Hour-by-hour distribution below.
