perhaps look at alternatives services i can honestly say wunderground has become the most unreliable api service over the last year .
dark-sky …not so good in accurate forecasting outputs not good outside of USA/Uk s . is highlighted in there data sources used .
apixu … goes a bit awol when using geolocation script based on lat lon returns a forecast from a location some 120km from here in istanbul, but works when using city option but may be an issue for those outside of larger city areas.
accuweather comes at a cost but good for specific location
ive tried some other services but restrictions in place and comes at a cost after a short period.
all,above are easily adapted based on they use the common json output .
