1.   Distant thunder rumbled over the mountains.

2.   In the distance, thunder rumbled across the sky.

3.   Thunder rumbled in the distance.

4.   As if on cue, the thunder of shelling rumbled in the hills.

5.   Across the West, afternoon thunder will once again rumble from the Southwestern deserts northward through the Rockies.

6.   Lightning zigzagged on the horizon and thunder rumbled and shook the panes of glass.

7.   The whole time, thunder rumbles incongruously in the distance.

8.   Thunder rumbles in the distance, and birds of prey circle the sky.

9.   Thunder was rumbling outside, and the Weather Channel was showing a lot of green for East Texas, a lot of rain.
