This morning we had a nice growly rumbly dark sky and suddenly it was all flashing thunder and big bangs and hard wet big-drop downpour. It reminded me of a thunderstorm that came through this weekend, on Sunday afternoon. We'd finished racing for the day and had rafted up the race committee boat in the Benjamin River (actually a cove, not much of a river) alongside one of the competitors. My dad and I were scoring the races, down below, but I could hear everyone remarking on the thunderstorm moving towards us. When I came up on deck and looked at it myself it was truly impressive. I've seen sudden storms before, but this was something new. The front was moving through and pushing clear blue sky out of its way. The sky just in front of the storm was bent sort of a pale yellowish blue, and the storm clouds themselves were amazing. It should have been the illustration in an atmospheric sciences book. The front was thick and black grey, with a remarkably sharp boundary, and the amazing thing about it was that, although most of the front was straight, there was a distinct part that curved, like a circle. Like someone was pushing a plate along through the sky. And the clouds that formed the curving front themselves were textured -- they were bent and contorted into the bend. You could see the rolling and the turmoil of the air. I've forgotten the little atmospheric science I ever learned but the sky has never looked to me more like an illustration of fluid dynamics, the mixing of air with different pressures and moisture contents. It was beautiful. And in the belly of the storm it was of course thick and grey with rain, with big flashing lightning and enormous drops hurtling down on us and turning the gravel roadbed into streams and sluices.
It might be my favorite rainstorm yet. My other favorite was in 1989, sailing in Newport, when a front came through that had an edge to the rain so dramatic that, from my place on the deck, I could count down the seconds until the rain would be at us just like counting down the seconds until a puff of wind would hit the boat. Usually, you know, you sort of gradually enter a raincloud, a few drops here and there, gradually thickening up as you move into its center. This wall of rain arrived with an edge as sharp as if it had been cut with a razor, so there was a moment or two when the port side of the boat was being showered with rain, while the starboard side was still dry. Sitting there on the dry side, listening to the dramatic rattling of the rain moving across the deck to me, knowing that in half a breath's time I would be drenched, was an unforgettable moment. I had never seen rain like that and loved the fact that the weather has so many forms.
I know it's dorky but I've decided to add a category to this blog for writing about the weather.
