How to get weather data?

Is there a ready solution to get the data about current temperature in the street? Yet, the simple thought of an idea to parse the website Gismeteo, Yandex weather, openweathermap.org a script in Python (but this solution might stop working if you change the design of the site). Ideally I would like multiple data sources.
You need to control the microclimate in the premises, not to put the sensors outside temperature in every home or building, based on outside temperature is formed, the temperature of the coolant. Climate controllers are gradually moving online, and the temperature sensors need to pull sometimes over 100 meters and location may be unsuccessful ("fiercely" or periodically servicewave the sun to unrealistic conditions).
Actually the question boils down to the fact that maybe there is a site that gives prepared data and are not need to parse. And maybe there is ready solution, the program / script did pull weather data and represent in a convenient form.
Something similar was discussed already here

But the decision is not published.
