Most weather systems move west to east so it's not rocket science to see what's coming even a couple days out.
You can burrow into each region for local real time info

For instance heading to PA you might reconsider.
Ontario Radar

Is part of the national radar network
so to see what's enroute you might go to a Sudbury radar

Judging the speed of a system is something you learn
Nature of the system....the sharper drawn the line ....the rougher the weather is coming
You would not want to be riding in front or through that front unless necessary to punch through.
Generally it will hot and muggy on the side it's moving to and cooler on the other....riding behind such a front is generally what you want.
Most weather you can ride around on long trips.
Ontario ....not so much but you can time within a 1/2 hour when a shower is coming...thundercells pop very quickly and then you just check often and look at the sky.
The hotter it is, the worse the Thunderstorms will be and it can be dangerous not just unpleasant to be in one on a bike.
The good thing ...you can see them coming.
Being behind one is really cool especially at dusk
Rode home from upper Michigan last year with a continous light show ahead of me. 975 interesting KM.
