Don't all those apps just get their data ultimately from the NWS?

- brootstrap 8y agoYes this is truth to some degree. However, you dont know what you are getting with an app. If you go to read the official NWS page, the forecasts are human curated by a pro. Apps likely are just taking model output directly and feeding it to you as gospel.
- PopePompus 8y agoSome commercial forecasters have a "wet bias" (https://en.wikipedia.org/wiki/Wet_bias https://en.wikipedia.org/wiki/Wet_bias). They intentionally overestimate the odds for precipitation on the theory that people are happier if it doesn't rain when they were planning on rain than they would be if it rained when they did not expect it.
