The station, and what usual means
The numbers come from NOAA’s daily record for the station in Allison (station ID 130157), 2 miles from the middle of Butler County. It reported 263 of the 282 days from Jan 1 to Oct 9; the 19 days with no report count as unknown, not as dry. Rain here means everything the gauge caught: rain, and snow melted down to water. A trace counts as zero. It is read once a day, usually in the morning, and each reading is filed under the day it was read, so an evening storm can show up on the next day.
Usual means NOAA’s 1991 to 2020 daily normals for this station, added up over the same 263 days the station reported, so a missing day counts on neither side.
Why this station: it is the only one inside Butler County that reported at least 90% of the days in 2026. Your own rain gauge can read differently a few miles away.
