Weather Network is innacurate

Last month I’m noticing that weather network option gives rather inaccurate historical data, which in it’s turn results in suboptimal flex daily schedule decisions. For example, it was a heavy rain in our area yesterday, and all local stations including national and personal shows between 0.2" and 0.45", while Weather Network confirms that it was rain but estimates it as 0.0". Does anyone had the same experience recently?

I know that I can switch to some nearby weather station, but I assumed that Weather Network is supposed to provide some more balanced experience than individual local stations(s)?
