What is the barometric pressure for today and was the pressure rising or falling?

Question

like the pressure of the air

Answer 1

Barometric pressure is different everywhere on the globe.  You must specify exactly where you are in order to get a reasonable answer to your question.

However; here is how you can tell very quickly what is going on with the barometdic pressure where you are:

If it is clear and sunny where you are, the pressure is high.

It it is cloudy and stormy where you are, the pressure is low.

If it was clear and sunny and is starting to cloud up and get stormy, the pressure is falling.

If it was cloudy and stormy and it is starting to clear up, the pressure is rising.
