While there are no weather widget elements in the ShortPoint Page Builder (yet), you can easily embed a weather report (or forecast) into your page by using the SharePoint Script Editor web part. You can insert a script editor into your page among ShortPoint elements and other web parts.

Step 2: Search for a Weather Widget Embed Code.

Step 3: Insert Weather Widget Embed Code.

In the inserted Content Editor, please click EDIT SNIPPET.

Next, please paste the code you retrieved in Step 2 into the script editor, press OK to save the changes and switch to render mode. 

This is how our result looks like on a page:

That's it!
