Real time weather

I have always wondered why an integrated weather alert system couldn't be applied. For example, last summer I was on a long road trip driving west across Tennessee. The clouds ahead were very dark so I asked my son to check the weather app. Sure enough we were under a severe thunderstorm earning with high wind and hail. We pulled over to a safe location. Had we not looked, we would have been in the middle of it. I get the community reported weather, but if it knows my route and there is a warning issued for something, it would be very helpful to be warned.
