Thank you, I was able to follow the able link to get county level plot. In the same way, city level is also possible but the geoJSON data does not have border and shows as a pin.

On another topic, was anyone able to add hover information and filter for above county level plot?

Cleaned things up a bit so that the maps load faster and the rough edges on weather map are trimmed:
