The station, and what usual means
The numbers come from NOAA’s daily record for the volunteer rain gauge 3.0 miles south-southwest of Maria Stein (gauge ID US1OHMC0007), 13 miles from the middle of Mercer County. It reported 283 of the 286 days from Jan 1 to Oct 13; the 3 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 gauge, added up over the same 283 days the gauge reported, so a missing day counts on neither side. The volunteer gauges started in 1998, so none has 30 years of its own; NOAA estimates the rest from long-record stations nearby.
Why this gauge: it is the only one inside Mercer County that reported at least 90% of the days in 2026. Your own rain gauge can read differently a few miles away.
