Nice shots.
The only difference between those shots and a good lightning shot is some settings and a healthy dose of luck. I was standing out in my driveway clicking away with my camera for an hour before I got that one shot. One hour for one decent shot. If you get a good storm that rolls right over you and you have a chance to shoot it from the front or rear without getting wet, or a garage you can stay in and shoot from, you can probably have a much more productive time of it than I can.
Good luck!
