Boston, Massachusetts: stratus, maybe cumulo-stratus when I first walk outside, looking up. It’s humid, warm, high 20s, little to no wind on the so-called Charles River. I walk along the water’s edge, all brown and slowly going, towards the Longfellow Bridge. I make my way gradually, pondering the slow pondering of rivers. Then, eventually, reaching a kind of narrowing of the path by a road’s edge, I turn back and see a large, black-grey cumulonimbus rolling over Cambridge from the north west. The wind whips in first, the air is cooler, dust blows up, trees begin to lose leaves and small branches. The rain is light at first, then larger drops. People begin to scurry; then they start running. I head back to a café near the hotel, rain beginning to increase; I go in, order at the counter, then turn to see torrential rain outside; lightening and thunder; people scurrying, running. Someone walks undeterred, drenched, without shoes. I sit by the window and watch, eating, waiting it out for about half an hour; lighter drops eventually. I begin to walk back. Some people are very wet. A small finch—or more likely what they call a house sparrow—appears under a curbside tree, hopping on his two little stick legs.
