The station, and what usual means
The numbers come from NOAA’s daily record for the station in Clark (station ID 391740), 2 miles from the middle of Clark County. It reported 284 of the 286 days from Jan 1 to Oct 13; the 2 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 284 days the station reported, so a missing day counts on neither side.
Why this station: 2 stations inside Clark 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.
