Tempest

Current conditions, an hourly forecast, a seven-day forecast, a 24-hour meteogram, weather alerts, and air quality — in the panel and a tabbed popup. Location resolves by IP, city search, or manual coordinates, and you can bookmark up to eight and switch from the popup header.

The data comes from public APIs through weathervane, the library the weather logic was pulled into back in 2.6.0. Open-Meteo by default. In Japan the current temperature comes from JMA's AMeDAS ground stations, because the blended model runs cold in East Asia. Alerts come from NWS, ECCC, MeteoAlarm, and BOM. No account, no API key.

It's self-distributed — on the AUR, from my own Flatpak remote, and from my own APT and RPM repos. It's not in the COSMIC Store.
