You can simply set up a hidden Automator calendar—it’s ideal since it doesn’t add extra CPU load as the calendar service runs automatically. Another option is to run a cron job with a pre-built Automator or AppleScript application.
You can also add a script to launchd. A GUI exists to modify scripts for it, and it's called Lingon.
Use the Calendar event to start an Automator action that fetches weather data via OpenWeatherMap's free API.
It seems you're looking to transition into becoming a software developer, likely by exploring options related to AppleScripting. You mentioned wanting to find an app or setting that could help with this shift.
