This page demonstrates the possibility of OWM Weather to show the weather conditions for multiple cities. We defined one Weather Post with the display and layout option. Then we used the same shortcode for all of them but changed the city id with the shortcode parameter id_owm. For example, the shortcode for the second city looks like this:
[owm-weather id="1003" id_owm="5128581"/]
Each city could also have its distinct formatting layout or map.
