I grew up in the tropics. The coming rain is easily sensed -- there's so much rain falling that at actually drives air from the upper atmosphere downwards ahead of it. A blast of cool, sweet air is a sign that the rain drops will be arriving in a minute or two.
When I had a motorcycle I could tell when rain was on the way using a similar method.
Most of the time I could be home by the time the rain started.
If you live in a cold climate you may notice the smell of snow before it snows especially the very first snowfall of winter. Maybe I'll create my own word and call it pnemakruos or "ice breath"
God I miss it.
