Right now the wunder map layers support below types,
Radar + Satellite
I wanted to know if Map Type ' Temperature' is supported, something as in this URL http://www.wunderground.com/US/Region....
No, it is not. If you looked at the documentation, and the documentation says that it has three available types why would you come to the support forums and ask if there is also a fourth? This isn't even hidden in the docs anywhere, it is very clear that there are only three.
