F22 Raptor in the Mach loop

I live in the Mach-loop training area and understand that the F22 Raptor has recently started flying through the ''Machloop''.
How can I find out when the F 22 will be flying?
Is there a site that gives which specific Military Aircraft are flying

I know when the F 15's,Tornado's & Hawks Jets are about as I can see and hear them, also Flight Radar also show airlines flight paths avoiding mid-wales on the days that training occurs.
Or is my best bet just to look out the window and try to identify them when there about?
