About this Sioux Falls forecast
Updated 2026-10-03 10:56 UTC, and refreshed automatically every few minutes. Forecast data is provided by Visual Crossing; radar frames from RainViewer; the 20-year normals and records from the ERA5 reanalysis archive. No national weather service publishes point alerts here, so only computed watches are shown.
Watches labelled computed are worked out on this site from forecast thresholds and are not official warnings — always defer to your national weather service. Need help reading a number? See the sourced weather guide.
