The rain is cooling down the air.

It is raining today.
Japan is in summer (Better to say, "It is summertime in Japan") and everyday we say " It is too hot, isn't it?" to each other.
But today we said, "Thanks to the rain, it is cool today!"
The rain cooled down the air.
Now, the thermometer which in my room is showing 27.5°（82℉).
How do you feel it? (You could say, "How's the weather on your end?" to sound informal, or "What's the temperature like where you live?") Hot, cool or proper ("normal" or, "normal as usualy" sounds better than "proper")?
Maybe the answer depends on your country's season.

The weather news says, "Maybe tomorrow, typhoon will come to Japan.(You could say, "The typhoon might come by Japan tomorrow." Or, "The typhoon might hit Japan tomorrow.") Be careful!"
I hope we can escape damage from it. (Another phrase you could use is, "I hope nobody gets hurt from it." Or, "Hopefully it doesn't do any damage."
