It has all the data. It's the data almost all other weather prediction services use anyway. Weather.gov gang raise up. I love spending hours on there digging through historic data too. Of course usually that just makes me since climate change is so apparent even in the basic data. But it's fun anyway
I am a huge fan of weather.gov. I can get all the data and forecasts I want without a single ad. All the other weather services use the same data, so there is no huge benefit to using anything else.
