Localizing weather by post location

I would recommend making a custom template and pulling in the custom fields into the ‘awesome_weather_shortcode’ function.

For example if you use ACF:
echo awesome_weather_shortcode( array( 'location' => get_field('location') ) );

Here is a list of the shortcode parameters:
