The station, and what usual means
The numbers come from NOAA’s daily record for the station in Alexandria (station ID 390128), 2 miles from the middle of Hanson County. It reported 281 of the 291 days from Jan 1 to Oct 18; the 10 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, too little to measure, adds nothing to the totals, but it ends a dry stretch: something fell that day. 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 281 days the station reported, so a missing day counts on neither side.
Why this station: 2 stations inside Hanson 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. Where snow is normal, a station that keeps a full record of both rain and snowfall comes next, over a nearer one whose snowfall record has gaps, if it is no more than 10 miles farther or twice as far. 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.
