weather loading into FSX, weather following the aircraft

[AceHigh]

Is their a way for the weather to load into FSX on the free flight page ,, so the weather is already current when the flight is loaded ? ( I hope that makes sense to you)

and

If I do not do a flight plan/ route and I take off from KJFK and just fly North ,,, will the weather load as I fly along ,,, in other words do I need a start point and end point for the weather to follow me to where ever I fly to?

Thank You
