Is there not a government run forecasting service where you are? In the UK the Met office is the only source of whether information I will trust. The rest is click bait.
And no ads, because our taxes pay for it. I'm not sure why anyone uses any other website at all. Maybe it's because of the conspiracy to privatize forecasting and extract rent from it.
I'm in the US, and use both http://weather.gov and http://windy.com. I think they complement each other.
weather.gov is best for the "forecast discussion" page, which often gives backstory on which parts of the forecast are certain and which are speculative.
windy.com gives multiple forecasts from different agencies, which also helps calibrate confidence. They also have some great visuals, and a very good interface.
