"with all the intensity of a summer storm"

I've decided that perhaps nothing is more ominous and deliciously visceral as hearing the low murmerings of thunder in the distant and waiting, as it grows louder--closer-- stronger until--- 

Now, it is just the pause before the downpour, the anticipation of drenching rains, the slight breeze through the leaves--flashes of lightning but still no rain.  

And now-- stronger breezes, louder rumblings, ----and the break!  Rain comes pouring down, in waves, tossed and turned by the wind, thunder louder, above our heads -- everyone is seeking shelter, and---

--I look out, from my now rain-soaked window, into the green grass, listen to the constant stream of water onto the ground.  Quiet.
