When is WX captured?

When I look at a historic track I see the wx overlay. Obviously the wx moves during the flight. Is the wx depicted in the FlightAware track the wx current at the end of the flight or at some other time during the flight? It’s always interesting to review IFR flights vs. the radar data to see how I was vectored through/around wx, but I’m not sure how to view the data.
