I just found this and wanted to share it with the community: https://www.codecademy.com/en/skills/make-an-interactive-website/topics/your-first-program/jquery-introduction.
The next challenge I need to clear is the Weather App challenge. I am a bit daunted by the amount of JS required but think this website will make things easier.
I completed the introductory course above and am now up to Dynamic HTML in the follow-up course: https://www.codecademy.com/learn/jquery. I think I will be more fully prepared to take on the Weather App challenge after this.
