If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket. The resolution source for this market will be the Met Office, specifically the figure for April 2026 under "rain mm" at the https://www.metoffice.gov.uk/pub/data/weather/uk/climate/stationdata/heathrowdata.txt link once the Provisional figure for the whole month of April 2026 is released. If the relevant data is not available by June 7, 2026, 11:59 PM ET, another credible resolution source will be chosen.
