It is strange that a European location would not return metric data, I agree, but it does seem to happen.
I notice that there is no metric forecast for Split, Croatia, for example. I sent a direct request using the Weather Underground website's API console (
http://french.wunderground.com/weather/api/d/docs?d=resources/apigee-console), and the field for "fcttext_metric" comes back empty. Here is part of the data:
{

"termsofService": "http://www.wunderground.com/weather/api/d/terms.html",

},

{

"icon_url": "http://icons.wxug.com/i/c/k/chancetstorms.gif",

"fcttext": "Partly cloudy early with thunderstorms becoming likely during the afternoon. High 77F. Winds SE at 20 to 30 mph. Chance of rain 100%.",
"fcttext_metric": "",

},
This is the data that VC is accessing.
I'm glad you found another location that worked for you.
