Over the Cascade Range in the Pacific Northwest, where unusual atmospheric conditions create a striking visual composition. The extremely low pressure (855.9 hPa) with steep gradients demands tightly packed undulating lines, while the moderate wind from the southwest (230°) creates diagonal wave patterns that flow across the canvas. The anomalously cold temperature of 7.5°C calls for Riley's stark black-and-white optical approach, with the high humidity and light precipitation adding subtle variations in line weight and spacing.
