Morgan Meis defends the most banal of conversation topics:
The weather is superficiality at its essence. Except that the weather matters. It is the fundamental tool by which nature adds flavor, color, mood to the variety of our daily experience. Nature is mechanistic in its functioning, tied to the laws of physics that give it rules. But it speaks to us in feelings. The light of a day is "like this." The shadows of winter make the world one way: brittle maybe, precise. The angle of the sun makes the world of summer another way entirely: smeared across the afternoon, vibrating.
That's why so many Romantic artists like the weather. They know that the weather does not make the world, but it does make the world "what it's like." So, the Romantics enjoy writing about the weather, and they enjoy painting the weather. They are cloud watchers and rain walkers. They wait for the light to be just so.
