The station, and what usual means
The numbers come from NOAA’s daily record for the volunteer rain gauge 5.3 miles north-northwest of Vienna (gauge ID US1ILJH0004), 4 miles from the middle of Johnson County. It reported every one of the 286 days from Jan 1 to Oct 13. 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.
This gauge has no NOAA normal, so this page gives no usual year or percent for it.
Why this gauge: 2 stations inside Johnson County reported at least 90% of the days in 2026. Mountain snow sites, and stations far above the rest in the county, come last, since their rain is not what the farms below get. Then the pick goes to one with NOAA normals, then the most days reported, then the one nearest the middle of the county. Your own rain gauge can read differently a few miles away.
