I actually read something wonderful in The New York Times. About the change from summer to fall, the feeling of it in the air:

“In the cocoon of the home, in the unaccustomed silence lately filled by the air-conditioner, the air flowing in feels, smells, tastes different — not just because it is cooler, but also because it is different air, hailing from a different part of the planet. Sultry summer nights are made of stiflingly hot air from Southwestern deserts simmered with emanations from the Gulf of Mexico into a thick gumbo. But now the jet stream, the ever-flowing border zone between hot and cold air masses, is making its tentative, give-and-take pilgrimage southward, and on cool nights, the air is fresh from the pine forests of Canada.”

Inhale deeply. This is magical sleeping weather.
