well this is what I did:
open weather application
push "plus sign" (bottom right corner)
push "my location"
your location will be showing on the googlemap and you see red pin.
zoom out and find your desirable location on the map.
drag the red pin to this location and push "Done"
you get the text "finding location", then you will have this location name and coordinates displayed... now just add this location and... you have it on the weather. then update the weather and it displays your custom weather conditions with others.
... at least it works for me.

I don't want to add another application.
You know what I mean?
