are the stations that collect data proprietary? And do different people have different information? Or do they use different type of analysis to come up with a degree or two of difference/different ideas about precipitation.
Edited to add an example:
I use the Wewow app and it lets you choose from different weather services and shows forecasts for each of them. For 11 PM tonight here’s a sample is what’s forecasted (c = degrees celsius, pop= probability of precipitation).
World weather online 10c 75pop
AccuWeather 12c and 48pop
Aerisb13c and 0pop
Thanks!

I find that they don’t vary very much.
But sometimes there is a band of bad weather coming though, and one service will predict it’s arrival 6 hours earlier than another. Or that it will pass 50km further north or south.
So if you look at the prediction for one town at one time it could breed very different. But if you look at the bigger picture you are just seeing a small difference in the predictive model.
